Evening all,
I seem to have a temperature issue with the car?

I don't know if its the guage (Std Sierra NORM temp guage) or I hav a real issue.

Symptoms:

Car runs from cold ok guage never starts cold always at the bottom of the NORM range.

I had it running stationary fro about 5 minutes and guage comes up slowly. I did about 1 mile around the "private" road at the back of my house ( I was actually checking the self centreing which was the job I was doing today). So going very slow.

Temp guage rose to top of NORM section and stayed there. I switched the fan on and it made no difference. Even now some two hours later and the engine is cold the guage it still up at the top of NORM.

I checked for air locks, I didn't see any bubbling in the header tank. My real problem is I don't have any baseline data to work with as its the furthest I've run the car.

I suspect the guage but I would appreciate some wisdom if possible.

Thanks.......Neil

Think I'd try a new temp sender just because it's so cheap and easy to change.

Think I may have a spare temp gauge too, will have a look in the shed if you want?

Those gauges need a voltage regulator, should be part of the dash setup, without temp and fuel will read very high on battery voltage, and go up even more when the alternator is pushing additional volts in.

Quick test, engine hot and turned off. Gauge high now turn on all lights etc and see if it drops a little, voltage regulator shot.

I really would not worry about it, my old Rv8 rover had an oil light on idle and displayed low oil pressure but went on for years. Guages are there to scare you!!!

There are several different ford temperature senders. Vital that you get the one that matches the gauge, not the engine. i.e. if the gauge was from an 87 cvh sierra then you want a sender for an 87 cvh sierra, even if you have now fitted a zetec or pinto.

temp sender sounds like its failing
