Title: Wter Temp Reading
Post by: Martz on 20 September 2006, 12:02

I recently replaced the temp switch (screws in the rad with two wires) and used a German Swedish part. It occasionally fails and the reading on my dash board does not register. Has anyone else experienced this problem? I am going to get a genuine one from the main dealer.

Cheers

i dont think this switch controlls the dash gauge. it simply tells the rad fan when to come on. on a valver the sensor for the gauge is on the head.

i have a tempramental water temp gauge also. though i believe the fault in my case lies with the actual gauge in the dash

On the 8v the temp sender for the dash sits in the water pipe.  There are two, a black one (for the dash temp gaugue) and a blue one (for the ECU?)

Any pics of where I should look?

Looking at the engine from the front on the right hand side there is a Black plastic elbow bolted to the block with a hose attached.

Sitting in the top of the elbow are a Blue and a Black sendor each of which has a plug attached to it.

To remove the plug you need to depress the metal clip and pull it off.

The Black sendor does the gauge, it is held in place with a metal horseshoe clip.

There is a rubber O ring to seal it.

Buy the sendor, the O ring and another horseshoe clip as you will probably drop the old clip and lose it in the depths of the engine bay.

The clip pulls out of its slot (self explanatory when you see it) sideways, have the new sendor ready fitted with its O ring and lubed with a bit of washing up liquid, remove clip, pull up old sendor, discard it, position new sendor in hole, hold in place with one hand and re-fit clip with other.

Re-connect plug, top up coolant and you should be good to go.

Only do this when engine is cold.

I could send you a photo but unfortunately I sold the car to Gibby as you know.

Cheers
