Question about 1991 Pontiac Sunbird
Location of the water temp guage sensor?
When in Run the needle comes off the peg, but does not read any temp. Found the coolant sensor and it checked ok according to book. The relay checked bad and was replaced, but the fan (checked good) still won't come on. Are these the same sensor? Is it possible the engine is not getting hot enough? There is no indication of overheating. Do I have two seperate problems?
Temp sensor is located under the air intake near the thermostat housing. No signal from there and fans would not know if needed.
