'94 Acura Integra LS, Overheating Problems

Q: Hi, I have a “94 Acura Integra LS, I just replaced the radiator and my car is still overheating like crazy. The fan won’t come on and I had the thermostat and fan sensor changed. Do you know what could be wrong??

- Kathy

A: The cooling fans on your vehicle are controlled by a fan control module. This little computer uses information from the coolant temperature sensor, A/C pressure switch and oil temperature to determine when the cooling and A/C condenser fans should turn on. If the fan control module is operating correctly, the cooling fans will operate at different fan speeds as the coolant temperature climbs, A/C request is made and/or when the engine oil temperature is above 221 degrees when the engine is turned off. The quickest check of cooling fan operation is with the engine running turn the A/C system on. The cooling fan on the A/C condenser should turn on shortly after the A/C system is activated. A word of caution: the engine in your Acura does not like being overheated. It is too easy to cause damage to the head gasket and checking account if the engine is overheated too much or too often. Before you drive the vehicle anymore you should have the cause for the overheating problem diagnosed and repaired. Failing to do so is only going to drive up the cost of repairs.
