For years now my 92 RS has had a temperature problem. The car does not over
heat however. The gauge in the car will always show the car running hot. I
replaced the water pump, thermostat, hoses, fan switch, and cooling water in
system. I just do not get it. Sitting at idle the gauage will go into the
red. ANy ides or any body else had this problem. Car has 305 TBI engine.
First, is the fan on at about 236F?
If not, then you have a problem.
Second, have you replaced the temp sending unit? The CORRECT one? There are
two...three actually, as one is for the fan..the bastard on the passenger
side under the manifold...
Ones for the ECM, and ones for the guage.
Barring that, you have a bad cluster...
