Classic Car Engine Overheating | Problem & Solution

in texas we have to worry a lot about engines overheating because when it's 107 like it's supposed to be today an engine can run 225 degrees which is way too hot in my opinion for a classic car so we start looking for ways to try to cool that engine down one of the things that we do is to make sure that it has the right degree thermostat in it in texas i try to run 160 degree thermostats and thermostats go right in that hole right there they attach to the hose that goes to the radiator the upper hose and the thermostats look like this there's one way that they need to go in as you can see and they have temperature readings on the top so if you look at this one you can see that it is i can get a good picture of it that's a 160. the other one that we took out as you'll see that's a better picture is a 180. on a fuel injected system they want you to run a 195 but in texas in the summer time it's not hard to get a car up to 195 degrees so a cooler thermostat's a good idea the thermostat housing is what this goes in and it bolts up right here you put the thermostat in and it opens when the engine water temperature gets up to 160 or 180 degrees to begin circulating inside the radiator which cools down the water and you can see the way that it's done is it has a big fan on the back side that pulls the air across the radiator now one of the things that people tend to do is put the fans in front of the radiator and they are not as efficient as one on the back side that's pulling the air across so always add your fan to the back now the other thing that we found out was that if you use the right set of relays on it the fan speed will actually pick up and we have those relays here in stock if you also buy a fan that doesn't have a high enough cfm it won't pull enough air across the radiator to keep the radiator cooling the water down to the temperature that we'd like so that the engine will run smoothly and under and under really i like a lot of mine to run 160 but that's pretty hard to do when it's 107 degrees outside but i over 200 you know you start worrying about whether you're going to do some damage to your engine if you want more information on how to take care of your car go to my website wilsonauto.com i'm barry wilson with wilson auto repair
