Chevy Camaro Is Overheating Q. Vince, I have been having a problem with my car for a while and hopefully you can help me. I have a 1994 Chevy Camaro, standard model, 3.4 liter V-6. Automatic transmission, fuel injected, ABS, P/S, and about 110.000 miles on it. My problem is with the cooling fan. The fan seems to never kick on. I only can run the car for a few minutes before the coolant starts to overheat and run out of the radiator.

I have replaced the fan motor and Engine Coolant Temperature switch. I have switched out the relays at the fuse box and still nothing. I don't know what else to check.

If it matters, just before this problem I had to replace the EGR valve, O2 sensors and the catalytic converter. This car is becoming a huge headache! Any help you can pass on is greatly appreciated.

A. In the real world, one of these cars should be able to run from a cold start-up for at least 15 to 20 minutes without the fan being needed. Maybe even longer. My guess here is a bad thermostat or a water pump that is not pumping coolant.

Even a misrouted serpentine belt causing the pump to spin the wrong direction could be a cause. The fans can be checked with a scan tool. They can be commanded on/off.
