Want this question answered?
needs a thermostat
My fuel gauge, odometer and radiator gauge isn't working and my radio says locked. How can I fix this?
We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
sticking float on the fuel pump, or malfunction in the float
220.
on the side of the radiator
Head gaskets!!
1990 Chevrolet Lumina temperature sender is located on the back side of the thermostat housing. The sender has a wire that goes to the temperature gauge.
Chevy sells a tank additive that removes corrosion from the sending unit that uses resitance to gage how much fuel in tank. Check your local dealer for the additive, the gage usually shows an erratic reading due to corrosion, bad fuel quality at the pumps.
Bad temperature sending unit? Bad gauge?
210 to 220 is a safe range.
you can buy the gauge at any auto store or even walmart and there are directions with the gauge.
