Thread: Cooling temp gauge works intermittently

I am tending to think it is the sender.
may possibly fit after market gauge in as I don’t think I can trust the gauge all so will fit run dry warning system.

Cheers

Well it's either....
1: Electrical problems with the car ... Have you got other electrical issues??

2: Temp sensor itself

3: Lack of coolant ( water then air ... water then air) ... have you changed coolant or been loosing coolant lately??

Earth out the wire at the sensor unit and see if the gauge stays "Hot"



Mike

thanks for the reply

there are no other eletrical probs, not lossing coolent and have not changed it either all though i will be doing it soon when I fit the run dry gadget, will try the earthing thing on my 4 days off.

Cheers

I'm inclined to think that the Temperature gauge itself is OK ... I would work on a lousy wiring issue or the sensor unit at the thermo housing is no good
