Temp Guage

[Guest topcarp2]

noticed today that the temp guage was not reading owt although i had done about 10 miles...switched the heaters on to hot and fan on to max...plenty of hot air and then the guage needle moved to its normal position...switch off the fan and turn the heater dial to cold and the guage drops back down and resisters nothing...any ideas???

Temperature gauge has become fan speed indicator. Could be an earthing fault.

Hi, sounds like a faulty wire on the temp thermister, its in an awkward spot on the right hand side of the head about 6 - 8 inches down, swine to get at. This happened to me i got intermittent readings, but mainly nothing and then sudenley it would shoot to normal and back again.

 

Hope this helps

I had this years and years ago on another car and the problem was the water (coolant) level had dropped and the sensor was out of the water, when the water level rose or moved in a different path with the heater on it reached the sensor and got a reading. Have you checked your levels and for an air lock in the cooling?
