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 wont come on and
I had the thermostat and fan sensor changed. Do you know what could
be wrong??

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.
