Try looking for the switch in either the water neck for the upper radiator hose or more likely on the side of the head, probably drivers side. It will have either one or two wires connected to it using maybe blade connectors with a push on plug. This is from memory so don't hold me to it.
I will doubt the connection or the sending unit. Hope this will help.
Your fuel sending unit is in the gas tank, mounted from the top.
Which sending unit? Oil or temperature? Or ?????
The temperature sending unit for a 1995 Chevy Beretta is on the front of the engine. It is between the front of the engine and the radiator inlet/outlet.
Check the emissions label. Failing that (if not legible) you can get a new label from the parts department or get the specs out of SI.
It is inside of the fuel tank. You will have to remove the tank to service it.
where are the temperature sending unit located on a 1990 Chevy engine 5.7
It is inside of the fuel tank, and mounted on the fuel pump sending unit.
Bad temperature sending unit? Bad gauge?
