Title: temperature gauge
Post by: PEZ_MK2GOLF on 12 February 2013, 23:28

Hi guys my 8v temp gauge seems to work but the rad fan only kicks in when the gauge reaches max is this normal or shouid it kick in around half way?

The red sensor light flashes when it reaches half way and then again when on max, would be greatfull for any help cheers chaps.

Does it have a 2 speed fan? ie, are there 3 wires going into the motor earth, speed 1 and 2

If so it might be the first speed is dud, and only kicking in on full speed when really hot. There is a sensor down the side of the radiator, check the wires are clean/connected tightly.

You could try powering up the fan with some wire, check both speeds to check the fan works ok.

Yeah, it will most likely be either a duff connection on the sender unit on the side of the radiator, or the sender itself that is duff.
