my temp gauge works but it will climb and then suddenly drop a few notches. gradually climb again then drop.
ive also got a prob with the fan only working when the ignition is off which is pointless. ive had the temp gauge up the top of scale cos of this. turned the eng off and the fan kicks in?? ive been told this is the fan switch in the rad but how can this be if the fan works. could it be the relay and what would be causing the fluctuating gauge??
