I have a 1986 Ford excort.
I seems to me that the heater should be putting out more heat.
So I put a thermometer in air coming out of the vent.
The temperature read about 85 degrees F when driving.
I parked and reved the engine and the temperature went up to
95 and then went down.
I don't know if these temperatures are normal.
Dose anybody know what they should be?
If they are not normal what would be some of the causes
for the temperatures to be low?
