Does the airconditioner in a cavalier help control engine temperature?

Okay lets set straight some wrong info that I see. Your Cavalier DOES NOT have a clutch fan. It has an electric fan controlled by the computer via a relay.


What you are noticing is most likely that the temp gauge seems to run hotter when you have the AC off and are in traffic.


Your Cavalier has a thermostat that controls coolant flow to the radiator. The thermostat is set to open at 195*f.


If you have the AC off then the electric cooling fan is normally off also. As the engine reaches 195* the thermostat opens and allows coolant to flow through the radiator. If you sit long enough the temperature of the coolant int he radiator will reach 195*. Since no more cold coolant will be entering the engine from the radiator, the engine temp begins to rise above 195* At a preset temp usually 225* the computer will command on the cooling fan and the temperature of the coolant will drop quickly. When the engine is back to 195* the computer will turn off the fan and the cycle will repeat.


When you have the AC turned on, the computer will turn on the electric fan all the time. The engine will never go above 195*





Hope that explains it.Does the airconditioner in a cavalier help control engine temperature?
Although the other answers so far are ultimately correct about your question. The fan on every cavalier I've seen, it is electrical (no clutch fan) however, If you have an actual issue and can give more details, that may help. There is a second fan for the air condensor that will spin up when the air conditioner is on to cool the extra heat produced by the air conditioning. Unfortunately, it is only about sufficient, not enough to pull more heat than the a/c is producing. If you want to help the heat, turn the heater on full with the vent fan on high...not a big help, but its some.Does the airconditioner in a cavalier help control engine temperature?
Unfortunately not. It actually makes the engine hotter as it creates more stress on the engine. It will also lower your fuel economy and decrease your horsepower. If it is an older cavalier the fuel economy and hp will be worse than if it is newer (the air conditioning compressor is more free running now). If is is a newer car, you probably won't even notice the fuel and hp.





I got this answer from my husband who is a mechanic so I hope this helps.
it doesnt cool the engine but it can surely make it run hotter.....the main thing controling the temperature of the engine is your clutch fan(the big fan in front of the radiator)....and the radiator.....
-No...but if you run it in stop%26amp;go traffic it may run hotter,but it doesnt control it.
