I have a 83 280 ZX .With a digital Insterment cluster.

My Coolant temp gauge is not working.

My Guess is that the sending unit is not working.

I see 3 possible units on my engine

One at the front of the thermostat housing the others

on the passenger side of engine one in the block the other

in line with the heater hose

Witch one controls the temp gage

Thank you very much:classic: :classic:
