Car Doctor Show 8-12-24 recirculation in AC, alignment, hurricanes, thermostats
It's the Car Doctor with Kevin Raywinkle and Tom Klexton on FM Talk 1065 called Kevin and Tom Nell at 3430106 with your car maintenance and repair questions. The Doctor is in. Well you heard the story of the hot rod race that fatal day when the Ford and the Mercury went out to play. And welcome to the Car Doctor Show with Kevin Raywinkle and Tom Klexton 3430106. If you have any questions, show us brought to you by UJ Chevrolet, Servin Mobile since 1939. Alabama Piping Supply and Ed Seaboo-Jid. And fabulous Seaboo-Shid, yes, on the hill in Spanish Fort. They do sleep with some good groceries, man. I stepped over there, I guess it was nice Friday. And had me some fish and some fried oysters and some of that cold slaw. I started to get me some fried dream tomatoes, but I swear I wouldn't have to play for them. I didn't want to break these like dogs, except what was in my belly. Right, right. I understand. Well I hope everybody's trying to stay cool somewhere. It's been pretty brutal here in the last week or two. I mean even today, good lord, it was tough. But we see as much as our air condition complaints with this 100 degree depth here, 120 degree. You know, not as much as you would expect, to be honest with you. Really? I don't know if it's the people that are realizing that the car can only do so much, or if the cars are doing better than what they used to. I know that they bought a car that I'm more familiar with, don't claim to know it that much about the newer cars, but the older cars, we have the recirculate factor on our air condition. Do you have that with the newer cars? Oh yeah. So you have a recirculate button, and if you don't hit that, you're not going to get the maximum cooling power of the unit or not. Yeah, it's still the same way, you know, what you get is, you know, the unit will only put out so much, and basically it's cooling the air that comes down, and it's able to drop it, I don't know, I think it's 40 degrees, 45 degrees. But if you can cool that air down that it's getting, and it can still drop it down, it's way more efficient. Because if you keep feeding it 100 degree air, your best you're going to get is maybe 70 degree air. Well, okay. Let me ask you a question somebody asked me a few months ago. If you just keep recirculating that air, what happens to the oxygen content? Well, that's why the cars are not 100% sealed up. Most of the cars, even when the fresh air doors close, still lead about 10 or 15% air in. Okay, okay. Yeah. Well, it's not 100% cut off. No, it's not. But you were recirculating, say, the majority of the air so that it will be better. Yeah. You know, it's keeping fresh air in the car because if not, people will be, if they're on the road for a long period, they'll just go to sleep and roll through. That's what I'm talking about. Yeah. Well, one more run that off, and I've got it rolling winder down, you know? Yeah. You know, all these cars have some kind of vents in the back part of them usually. That's letting air out of the car and the air condition is drawing air into the car. So it's constantly pulling, you know, pulling air into the car. Okay. Keep it fresh. Yeah. Well, you know, if it was a danger, we would already know about it here. You know, 100 years, 110 years of the car, 120 years of the cars, you know? Right. Well, back then, they wouldn't sealed up enough to worry about it. Right. Yeah. Well, they didn't have air condition. Anyway, we had the full winders open, you know, for about an hour air conditioner. Well, even in the winter time, I wouldn't shield it out. Yeah. Even winter time, when you got your winders rolled up and got a heater on, you know, that's, this car still weren't sealed up enough to for it to be a real issue. Sure. Okay. You know, now the cars are sealed up way better, you know. You can tell just by driving them how much quieter it is inside the car, but they still have to circulate some, some fresh air into the car. It is, my car has, I will always talk about my list, but my car has no road noise whatsoever. Yeah. Yeah. Except if I put 40 pounds of air in those tires, rather than 32 pounds of air, then I get a little bit of road noise, but that has to do with the sightness of those sidewalls on the tires, you know? Yeah. Yeah. That's like putting bigger springs in it. Right. Like cars. Well, you know, in this, like a town car, it's insulated quite well. Oh, yes. You know, everywhere, you know, the, the firewalls and back, back firewall and all the doors and, and all the body panels, the floorboard, the roof. Everything's got insulation in it and, you know, it, it keeps it quiet. It does. Well, I enjoy it. Yeah. Listen to my tapes or listen to my, my phone or, you know, what I, I don't have Bluetooth in my car. All right. So I have both Bluetooth speakers and then I can use Pandora or whatever, whatever I want to listen to on my phone and pick all of it. But I, you know, the sound system is good anyway, but it's, you know, it's, it's nice and quiet, man. I love it. Yep. Yep. It makes a big difference when you run running down the road is to have the, you know, get rid of some of that road noise. Yeah. You know, but what you're going to always have a little bit, but yeah, I'm not much. Yeah. But not much anymore. Yeah. Well, you know, everybody thinks that you put a thermometer in the, in the vents on your dash and you should, should be getting 40 degrees or 45 degree temperature. Yeah. Well, it's the right time of the year and the winter, you can do that or at night when it goes down a little bit. Yeah. But normally the, you know, you've got to go off at, what is it called, ambient temperature or the outside temperature, right? Right. The low air is the ambient air is, it's only going to pull that down like 30 something degrees. Yeah. Yeah. I've heard that figure before. Is that still a good figure? Right. Right. Yeah, it's 30, 35 or so. So if it's 100 degrees, if you get 70 degree air, right, you're getting 65 to 70 degree air blowing out of the vents, right? You're doing pretty decent. It's working. Yeah. But that being said, if you, if you recirculate that air, then you can, it can, it'll drop a few degrees. It's not going to just get it to 60 and then all of a sudden it's going to be blowing 30 degree air air out, you know, that would take a while for it to ever, ever cool it down that much. But, you know, you got to remember you've got so much infrared heat that's heating up those body panels and the windshields and side glasses, even though they are tinted and insulated a little bit. Do we, do we see a lot of cars coming now that have some, what they call factory tint? Most of them have some kind of UV tint in it. It's not really a, not really a tint as such, it's not like we would call tint, that we are accustomed to over the last 30 years or whatever. It probably darkens it 5% maybe, but it does block a lot of the UV rays coming through. Well, you know, they've got this, they've got this new ceramic tint now that, oh, seems to be working real good and they say that'll pull it down about 18 to 20 degrees. Yep. It does a good job. I had my old truck, you know, you got a back glass right behind your head and windshield the side glasses. Oh, yeah, yeah. The back glass sure were. They're not sealed up very good. So, the air really wasn't working that well and I had the windows tinted and it made a huge difference. Oh, cool. Okay. Let's get a shower. The collar on mine, so the collar you with us? I was thinking to call you on a break because we have it hurt from you and I was getting to the point where I was worried about my boot. Well, do not worry because my hair is not growing. So, all right, all right, all right. Well, well, you've been cold man, up whip, I guess we're doing right. We're doing? Yeah. We walked in here to get. Mr. Engineer, you're doing okay, sir. I'm doing fine, doing fine. That's good. That's good. Glad to hear all y'all tonight. I'm ready for a good, good show. Yeah. What here did they put the first power stern pump in the car and what car was it? Power steering pump. Yeah. Hold on, let me Google that. Get it on that, right quick. I'm going to take a wild guess and say it's Chrysler back in the early 50s. 1961 Chrysler Imperial. Whoa. Well, I know they had it before then. Because... It didn't work out, though. Well, it worked. It wasn't the best. It wasn't the best. It worked. It worked. It worked. It worked great. Yeah. Because I know some of the 55 Chevrolet you could get with power steering. It was pretty rare, but you could get it and the Cadillac's in that. Yeah. But, like I say, I can't remember exactly when. I think there's one Chrysler in period. Yep. Yep. They had it. You've got a question. What size motor was in there? Probably... You get one in period. What size motor was in there? Probably the 4-13. I think so. Full barrel carburetor. Oh, yeah. Yeah. Yeah. Yeah. It's a time you crank it up and there's three gallons of gas gone. If you were lucky. Of course. Yeah. Hang on. Hang on now. Yeah. Sound like it's time for us to take a break and let you hear from our sponsors and we'll be back. Well, all right. It's the Car Doctor with Kevin Raywinkle and Tom Klexton on FMTalk1065 called Kevin and Tom now at 3430106 with your car maintenance and repair questions. The Doctor is in. And welcome back to the Car Doctor show. This is Car Doctor Kevin Raywinkle along with Tom Klexton. You have any questions? Give us a call. Send us a text 3-4-3-0-1-0-6 but I believe we do still have Marcus on line with us, Marcus you with us. I am Kevin. Do you work every weekend? No. I thank God I only have to work once every fourth. We can. Well, Tom is going to plan and we're all going to get together including the engineer. We're going to all go eat lunch one day. All right. Tom is going to work on that. Well, when you ready? Listen, we're going to take John here with us. All right. Yeah. Yep. Yeah. Thank we can get him to pay. Tom's going to do that. We can do that. We can make it work out. Yeah. All right. Well, you'd like to go to Saturday? Is that what you're saying? Yeah. All right. Well, you'd like to go to Saturday? Yeah. I'm a Saturday. All right. Well, you'd like to eat that? Wherever you go I go. I'm not a big seafood guy. Okay. Now, oh, oh, oh, on top of the hill, they got, they got, they got everything you want. Well, you said it is? Yeah. Yeah. Okay. You can get hamburger, you can get chicken. Oh, yeah. You can get alligator if you're stronger than that. Yeah. Yeah. Yeah. Yeah. Yeah, you get alligator bait too. Yeah. Yeah. Yeah. We make that work do it up, man. Yeah. We're going to take care of it number one. We make it work maybe in a couple of weeks. Yeah. We make that work. All right. Well, listen to everybody enjoy themselves now. All right, brother, man. You do that too. I'll stand you large. A little sweetie on there. No, I'll go. No, that was my niece. Oh, yeah. Okay. Okay. Okay. All right. All right. Keep it clean. Keep it clean. Yeah. All right, brother. Take care. Appreciate your call. All right, buddy. I was good to hear from you. And it looks like we've got another color online. If we can get them on there. Call you. Hey, guys. Hey, guys. Good to hear from Marcus again. I was starting to worry about him too. Yeah. He's going to have to call a little bit earlier, because he's cutting into my time now. Oh, okay. Yep. Yep. You just got an invitation to go eat with us. Well, yeah. That sounds like a good idea to me. Yeah. Yeah. I can't believe he don't like seafood, though. I mean, I'm not a big seafood eater, but I can eat some shrimp. You can't fish like nobody's been in. Oh, yeah. I know that feeling. I know that feeling, buddy. Yeah. Me too. I like me some shrimp. But, you know, guys, before I get to the meat of my question, this is a little deal. I caught on YouTube the other day. Have you ever lined your tires up or done a front end alignment with a piece of string? Yep. Oh, yeah. Yep. I still do it. Running all the way around a car, but doesn't that only work for tow? That doesn't work for camera and caster, right? Right. Yeah. It doesn't work for camera and caster. You know, the other shortcut you can use is a tape measure and a framing square. That was the old school. That's why we used to do it. Yeah, I've lined up on many rides car that way. Well, I've actually seen them goofballs on TV that they call an ass car. I've seen them do that on occasion. But I've also done it with a broomstick. Yeah. Yeah. I mean, you can get it pretty close. The caster is the hardest thing to come up with unless you use a framing square because you've got to check it and then turn the wheel and check it again and come up with your caster that way. I mowed the '68 truck. It hadn't been on the alignment machine. I rebuilt the whole front end and all that. But I did it just sitting there in the shop. Yeah. You know, which brought friends square out and got it all where I wanted it and it drives as straight as it can be. Well, we used to use the strings and jack stands. They use lasers down it, you know? Yeah. Yeah. When you actually do the camber with like a little torpedo level or something like that, just to kind of get it close. You could? Yeah. You could. You know, and you can even do the caster that way if you know what you're doing with it. You know, there are ways around some of the have to put it on the alignment machine. You know, of course your average person is not going to be able to do that. Right. But it's... Well, you know, we used to tape measure it back in the day and you could even use your framing square that you use to check your camera caster and if you had a big enough one, you could cut slots in it and use it to check your tooling it. Yep. Yeah. You used like toe plates. You know, you used two tape measures and you used some framing squares for toe plates. Yep. And you could do it that way. But am I right or am I wrong? The toe is what usually wears out your tires the most. That would, if it's off, yes. Yeah. It will wear the tire more than camber will. Right. It feathered off really. Yeah. Because at that point, the tire is dragging across the asphalt. Yeah. If the toe is off, if you've got your camber off, it's just leaning on one portion of the tire harder than the other. It's not actually dragging it. Right. You know. The toe is dragging, but the camera caster, it's just you running on lesser patch tire. Right. You're like running with lower air on your tires. Yep. Yep. Well, yeah. That's the same principle as the toe in. That's going to cause it to scuff the deal. And you can actually run your hand over it, over the tire. And if you feel that, it's like running over your hand over fish scales. Mm-hmm. You know, it's got the little ridges and all that. You should feel ridges when you run your hand over your tires. Yeah. Slide it across one direction and it'll be feel smooth. Right. The other way you'll feel like sharp edges. Right. Right. Yeah. And that's because of the wear. Now, I actually, my old Ford F-150 that I had years ago, I used to drive that thing down the road and just let go of the steering wheel and see which way it would pull and would adjust my toe. And when I finally did take it and had the alignment done on, dude said I had it within the 30 seconds of an inch. So I think I did pretty good on that one. Well, yeah. That scenario will work if you're sincere about it. Yep. I mean, it's like you can't have it due to it. Yeah. Well, you know, guys with the little storm that blowed up in the Gulf last week, you know, I know this is a car show, but and one of the questions is what can we do to get our cars ready for in case we do have a big old hurricane coming this way? Big things get them out and get them away from the coast. Yeah. So that's the safest bit, but. Away from trees. Yeah. Away from trees. You know, it's really all about, you know, me personally, if we have a big storm coming the only thing I'm worried about my car is I'll keep it away from trees. If I have somewhere covered to put it, that's where it'll be and it'll be full of fuel. Right. Right. And what about our equipment, say our generators that if we lose power, we're going to have to have them bad boys and now I was a friend of mine that used to work up at this Alabama power company place up the road there. He told me, you know, everybody knows you need to go out there and start the generator and let it run every once in a while. Right. But he told me, if you don't put it on load, you ain't doing no good. All you're doing, just making sure the motors run it. Right. If you don't put it on load, your magnets are going to lose their magnetic ability to generate electricity. Yeah. I mean, at least take and put a fan or something on it that'll draw some current so you know that it's generating power. You know, that is a good point. You know, you do want to crank it and run it, check your oil, all that stuff. At least once a month, you really need to fire it up and let it run a little while. You're doing that, like I say, put something on it to give it a load, that way everything is working. You know, the worst thing you can do for anything like that is just let it sit. Right. Yeah. Well, you know, one thing that I found out that you can do, and if it's not real fun at this time of the year, is put a base heater on it, and put it on wide open. Yeah. Because if you're going to put a load on one, that's going to do it. It'll definitely do it. It'll definitely do it. It'll definitely do it. It'll definitely do it for sure. All right, guys, y'all have a great night. I'm going to continue listening, and you don't have a good evening, and we'll talk to y'all next week. We'll make sure your name is old and dinner lit. There you go. Thank you, Dario. Have a good five. Have a good five. Have a good five. Have a good five. And we'll be back after these messages and let you hear from our sponsors. It's the car, Doctor, with Kevin Ray Winkle and Tom Klexton on FM Talk 106-5. Call Kevin and Tom now at 3-4-3-0-1-0-6 with your car maintenance and repair questions. Now, Doctor, he is in. And welcome back to the Card Doctor show. This is the Card Doctor, Kevin Ray Winkle, and along with Tom Klexton. You have any questions? Give us a call or send us a text, 3-4-3-0-1-0-6. Well, we got through our normal crowd of listeners there this evening, so if you have any questions, please give us a call and let's see what we can do for you. I know there's got to be some people having some overheating problems or some AC not cooling problems. There's no way it can't be happening right now with a 100-degree heat we got. Oh, yeah, yeah. You know, and it's so hard on the cars anyway. Yeah, I just had a problem with my car here about what, three weeks ago, running hot on me. Something happened to my cooling fan. Yeah. You know, the cars don't have a fan on them anymore that's running by a belt or anything. Very rarely. Yeah. There you live. It does a little electronic motor running. Right. Off of some juice or something. Yep. And my fan didn't lock up. The fan blade was still free to turn in, but something happened in the motor. All right. Only in the motor locked up, so the cars run hot. But as soon as I found it, I shut it off, because I didn't want to set my motor up anything. Yeah. And so I shut it down, and man, it kicked all the water out of it. What the heck? Yeah. I found that rock, so I went ahead and changed that fan out and got, you know, and that's another thing. You know, there you are. Check with, uh, tried to get one for my car through the forward, and they were going to have to order it. It was going to be a week. Yeah. Then I said, "Yeah." Well, but I said, uh, so I had to go ahead and check with Billy. My old buddy, Billy Jones, done a car quest. Yeah. There's not a car quest. And now it's, uh, advanced. Yeah. And, uh, he said, "Well, we haven't seen to have a problem." I said, "What are you talking about?" He said, "We have about four grades of those fans." I said, "Well, I want the best one I've made, because I don't want it to go down on me on the roads." Right. You know? Right. So it was only like $25-$30 difference. Right. But, you know, but I noticed the sound of the fan at all now. It's a little bit different. Yeah. It's a little stronger than the factory one, but I'm sure the factory one had been injured for quite this year. Right. And it may have been slowing down a little bit over years. Yeah. Um, so it's, uh, as quiet as the cars are anyway, you know, you don't really hear the fan once you close everything up. No, you don't. I don't hear it in the car. Um, so. But when I shut down, I closed, shut my car off, and I opened the door real quick, it's still running some. You know? Right. It hasn't stopped yet. Right. Yeah. A lot of times it'll run for just a, I don't know, a few seconds. Yeah. Whatever. Um, after you shut them off, so it kind of helps cool down the engine compartment and the radiator and everything else. Yeah. Well, there's, there's an area I'd like for you to cover. Thermostats. Mm-hmm. When that car was running a little hot like that, I told the mechanic just to make sure that we changed the thermostat. Yeah. And we also checked the switch for the, the, for the fan. Right. To make sure that that's something wrong with the switch. Mm-hmm. But the switch was all right, but didn't even check the thermostat. We just arbitrarily changed that. Right. Now, I understand that there's something inside of a thermostat, and they call it wax. So you'll, they call it two or three different names in the industry. Said that it melts it down when the car runs really hot, so that it opens the thermostat up and it won't close again. Yeah. Well, it has a, a piece inside, and I'm going to draw a blank on what it's called, but the, it does have a thermal expansion component in there that expands and it will push the thermostat open. So it's, some of them did use wax of some sort at one time. I don't think that's what they use anymore. Right. But, you know, it's, the thermostats are so much better than what they used to be. We still have some problems with them once in a while, but they've actually gotten smart and they've figured out a way to make them fail open. Okay. You know, where they used to fail closed, it was quite often. Right. Right. But now when they fail, they fail open and the worst thing that happens is it doesn't run warm enough to run all the tests and, and get the emissions clean as clean as clean as they should be and all that. But at least it doesn't push down on the side of the road. Right. Yeah. But it does warrant you to make sure that if you have to ever replace that cooling fan. Yeah. Make sure that they, they do check the thermostat and make sure that's another component. And don't ask if it's good, just say replace it with a good one. Yeah. Yeah. Don't, I don't want none of the cheap stuff on my car. Right. Right. You know? Yep. They say three different grades apart. Oh, yeah. Yeah. You can pay less for it, but it's going to be a lesser part. Right. Well, the stuff don't last. It's going to put you down somewhere. Exactly. And my thought was, you know, here as much as I run the roads, I'm going to really go halfway to Jacksonville. My car goes bad. Tallahassee. I don't know about it. Tallahassee. Right. You know, I can't call my buddy and come get me with a record. Yeah. I can't go to a shop where I know the guy that I go in there and stand there and watch him work on it. You know? Right. Exactly. Well, I'm trying to repair my car when it needs repair to, you know, make sure that I don't break down on the road. Yeah. Exactly. It looks like we've got a couple of callers who better get the answer in here. Tallahassee. All right. Which one are you going to? We're going to eat. All right. Well, getting you, you kind of killed my thunder there because what Tom was talking about was what they call a fail to open thermostat. But if you can buy them now, if you'll look at them real close, they've got a little, about an eighth of an inch hole in them. Yep. That it's going to flow a little bit of water, even if that thing fails close. Right. Right. So we're going to get a little flow of water and it'll get you to where you can get some cool water and that thing. Yeah. And really, what that's for is it's not big enough to cool the car, really. But it's big enough to let the air pockets pass through. So you don't get an air pocket because one of the things that happens with a thermostat is it won't work with air temperature. It has to have water on the thermostat part of it for it to function properly. So if it doesn't have a way to pass some air through there to let the water get all the way to it, it will not function properly. So it's, go ahead. Just a little old school, does anybody remember how to check a thermostat to make sure it's working? Well, if you want to take it out and put it in the pot with the thermostat with a thermometer in it, you can. Or put it in the pot of boiling water and see if that rascal is going to open up. Yep. Yep. And that's one way to check it. Of course, you know, the problem is we don't have anywhere to boil water at the shop. So that's a little tough for us. You can go out there and sit it on the sidewalk right now. Oh, I know. I'm roughly boiled. Yeah. Yeah, it wouldn't take long. It wouldn't take long. Well, you know, y'all talking about thermostats. Do we have another caller? Yeah. I'll let y'all get on to your next caller. Yeah. I'm going to ask you about it. I'm going to break up something here about a 100-degree thermostat in a minute. Okay. All right. I'll just hang on there. All right. Hang on. Down three. Call you, Willis. Hey. How y'all doing? How y'all doing? Oh, we're hanging in there. How are you? All right. Listen. How long? Two questions. Oh, how long can you get away without changing your cooler? And when you finally do change it, you say, "Go ahead and get a thermostat when it's working or not." You know, a thermostat can last a long time, actually. But your coolant should be every, I believe. And I'm drawing a little blank spot there, but it's, I think it's every three years or two years. They want you to change the coolant. It'll be in, it'll be in your owner's manual. Right. And it'll tell you when you should change it. And some of the different manufacturers will, you know, give you an extended period of time. You're going to see two years, three years, five years. Right. And like a dummy, I'll let mine run for ten years. Yeah. Okay. It better take it to the gorilla. Oh, you know, of course. It'll be too expensive to get your coolant changed, eh? It's not, it's not terrible, but it's not cheap either. I mean, because most of the time they're going to do what you call a coolant flush where they're going to run a machine on it that actually flushes, power flushes through the, through the coolant system. It does a better job. So, you know, it's, it's worth it. It's worth it. You know, in a lot of, in a lot of places, otherwise, we'll just do what they call a draining fill. We're basically all they're going to do is drop the water out and maybe put a hose in there and kind of flush it out a little bit. The flush, the flush deal with a machine on it is the best if you go to keep the car. Yeah. Yeah. Yeah. All right. Have a stay working. Don't bother. If it's ten years old, don't bother. Just leave it long. If it's working, you know, if it ain't broke, don't bother. If it ain't broke, don't fix it. You know. You don't have to worry about changing that. No. If it's still functioning properly, then, you know, it should be fine. Mine would probably still work, but I didn't want to take a chance on it. All right. That's the reason I just went ahead and I knew that the cars, my car was, you know, it's got 15 years on it. So, '07. And I'm sure it had never been changed. So, I said the heck with it. I'm going to change it because I don't want it running hot on me and I don't want to lose my motor. All right. Okay. Okay. All right. That's just cheap and short. Okay then. Thank you, bro. All right. And I appreciate you. So, I'm like it's time for us to take a break. And we're going to let you hear from our sponsors, and we'll be back. All right. That's just cheap and short.

But we still have Jarhead online with Jarhead. - Yep, I'm here. - Okay. - Yeah, let me ask you. - Probably. - You're down. - Car guru. (laughing) - What? - Go for it. - What heat-range thermostat do you put in a marine automobile type engine, combustion engine, that is running the water out of the bay or whatever, salt water, whatever's running through there and cooling the motor? - Well, just tell the truth. I didn't even think they've had thermostats in those motors. - Yep, yep, they do. - They do? - Well, I know, you know, water bowls at, what, 212, 214? - 212, yeah, without pressure on it. - Without pressure on it. - Without pressure on it. And in the old power generating industry, the more pressure you got, the higher the boiling points. - Right. - So, and what most thermostats are set, what, 30 to 40 PSI? So you got a very low boiling point? - Well, most cars are set, and actually about, most of them around 13 to 15 pounds. - Okay, well, that's even lower than what I thought. - Yeah. So, I mean, if you look at the top of your radiator cap, it'll usually have like a 15 to 17 pound cap on it. You know, we get on our round track stuff, you know, race car, we go as high as like a 30 pound cap, right? Just for a simple fact that we're not supposed to run any kind of antifreeze, anything like that. We can run something they call water wetter that will raise the boiling point some, but you know, we get, our cars get fairly hot sometimes, and the worst thing you can do is have it get hot and bowl of water out of it, because... - Well, that was my question was, if you being us down here in this hot weather, if you've got a thermostat or a cap that has a higher pressure rating, doesn't that help your car a little bit? Because the boiling point is a little bit higher than what normally would be with a 10, 13, 15 pound cap. - Well, you know, the first thing is, well, yes, that is true, but our cars are all supposed to be running antifreeze in them year round, so during the, it's an antifreeze coolant, then what it is, is it will raise that boiling point quite a bit, now don't ask me exactly what it is, I think it's round 250-ish, I think, for the bowl. With coolant, and instead of the 212, so you have a lot better chance of keeping the car cool, because the actual temperature doesn't typically do the damage to the motor, what happens is, you boil the water out, and those air pockets in the motor is what does the damage, because it can no longer cool that part of the motor, and you'll have hot spots in there. - Your steam won't remove the motor, it won't absorb the heat from the internal components of the motor. - Yeah, and it'll just start building temperature from there. - That's where the air pockets will mess you up. - And your oil can only do so much. - Sure. - Right, right. It's just, I mean, it's just like with our round track stuff that we do, with our race motors, if we get a spring leak or it gets hot and it spits water out of it during the race, if I'm gonna have a failure, it's gonna be on that left cylinder head, because we have such a centrifugal force on that car, all the water's gonna tend to run to the right side, the left head is gonna have an air pocket in it. - Right. - And we had that happen earlier this year, and we got, we got. - Seize the, the valve is up the guy. - Seize the guy in the head, because that left head got hotter, yeah. The car never really overheated, it was running 260, but it was not, you know, what I would call extremely hot. - Right. - You know, if it hadn't pushed any water out of it and was running 260, I would never, never thought about slowing down and coming in. - Well, we say, yeah, we say I'm running 260, 270, even at night. - Oh, yeah. - Now when they're showing the gauges at all. - Yep. - It's not the best thing for it, but it'll run. - You know, and the other thing is though, if you start adding into your cooling system, it's supposed to have seven pounds, and you run, say, 12 or 15 pounds on it, then we have to consider the age of the components that this is running through. Will the components, the hoses, will the radiator and will the other things that the water and pressure is running through, will it sustain that different pressure? - Right. - Right. - But we have to consider that, Joe, here. - Well, there's a, like, there's a lot of things there. - I thought you was this though. Or a boat that's running salt water to cool it through the motors, and normally they run out the exhaust. So it's running into the cast iron exhaust or some of them have stainless exhaust now. The, I don't know what it is, I'm not a chemist, but if you run a car thermostat, let's say it's got a 180, 195 degree thermostat in it, in that those manifolds will rust out and deteriorate within a matter of a couple of years. If you run a 160 degree thermostat in it, then it won't, they tell me that 160 degrees water, salt water, the salt will not drop out of 160 and accumulate on the components and pieces that it's running through. But the same water, for the same water, same circumstances with a 180 degree thermostat, well, the water will drop out, the salt will drop out of the water. - Well, you know, maybe that has something to do with the heat of the water and it's dissolving that salt. Now, that might be something that you could ask Sean and call in on Saturday when he's in here doing his little show with, you know, when they didn't speak. Yeah, with Mike Ward, because they were talking about it, about flushing your motor and you have got to flush it and get all that salt out there because it's gonna sit up in there and it's gonna corrode and the temperature may have something to do with dissolving that salt. - Well, if it's dissolved and it's not sticking to the components, so I'm not worried about that. - Yeah. - Well, it goes right on out the exhaust. - Yeah, well, when the salt drops out of the water, though, and sticks to the side of whatever passage way it's going through is what's causing the damage. - Right. - Well, that's just like I was watching a little video the other day about why they paint the bottom of boats red because you too, when the old boats, you know, when they were sitting in salt water, when they made out of wood, the salt water would corrode them. Well, so they started painting them red, but then they had particles sticking to them and it kind of slowed everything down and corrode everything so they come up with a special paint that eats the barnacles off of the stove. - Yeah. (laughing) - Now, hey, America ain't gonna do anything. - So, yeah. - America ain't gonna do anything, babe. Good, good talk with your head. Who rock? - Yup. - All right, who rock? Have a good night, guys. - It's up, bye, brother. - Sounds like it's time for us to give it up and go home for tonight. I want to thank everybody for listening to the Car Doctor show, and I won't be back next week, but, yeah, so we'll do a best stove show. So, but we'll be back the week after that. - All right. - Come on, stick it to the ground.
