Temp gauge etc

Hi guys,

Been having an issue with the old temp light flashing.
So went for a spin in the car today, light on then it went off eventually and te temp needle in the gauge was half way?

So decided to change the sensor the single pin one with the red and yellow wire it has the black shroud. The light comes on for a few secs then goes off even if I don't start the engine.
Is this the feed to the gauge eyc or is there another plug somewhere?


Is thus something to do with it as well?



Cheers

If it flashes then goes off after a few seconds I think that is normal as mine does it and sure my last one did aswell. I've had a few probs with mine lately and there is another sensor that will get the light flashing and thats in the top of the expansion bottle.

Cheers Dan,

It's just I don't appear to have temp gauge now.
Even when the engine gets up to temp and the fan kicks in.
It boiled over yesterday. Will give it a try today from cold.

Cheers

been out to her this morn after reading a few posts.

Whether I connect the sensor or not on turn of the key it flashes 10 times then goes out. Even shorting to the block did nothing?

So started engine and left to warm felt the bottom rad hose  was cold for a while, after 10-15 mins it started to warm up. So presume thermostat is working, checked feed back to header tank flowing beautifully so no issues there. A couple of mins later cooling fan comes on so all good there.

I am thinking if I have made the new spade connection properly as I took the old one off.

I am leaning towards the Dash coming out and having a look see.

Is there a seperate sender for the actual temperature gauge as the needle isn't moving at all?

cheers

Reading another post it mentions a sender via a black plug with red/yellow and brown.

I have located similar at the back left hand side of the block which connects to the pipe work that runs found the back.
Mine is black plug red/white and brown.

Is this the same thing the post refers to shorting the pins so the gauge should go up Indicating a faulty sensor

the post about the red/yel and brown is refering to later models which used a 2 pin temp sender, so dont worry about that. all you need to do is earth that red/yellow wire, if gauge doesnt go up to full then you have a wiring problem somewhere, or a loose copnnection to the dash.

look at the relay 43/42 above the fusebox, this is the coolant level control unit. if this goes faulty it can mess up the dash temp, yank it out and see if that helps. look in the back of the socket for any yellow/red or yellow/blue wires, trace them as far as you can see if there are any snapped wires

the yellow/red wire from the sensor should be joined to a wire from the level sender control relay. sometimes the sensor wire goes to fusebox and a wire comes out from the same pin to relay, sometimes sensor wire goes to relay first then another wire from there goes to the fusebox. hope that makes sense!

Cheers fella, as per the Pm you sent lol…..

Tapped the binnacle a couple of times and it came right …oohh the shame.

Gonna take the clocks out and place some tape under the blue connector, for better contact and give the contacts a clean.

Plus will investigate the other points..

That should help..

cheers

coolness, hopefully an easy fix then!

Never usually is lol..

Ahh finally found this thread as I'm having the same problems! Gonna sort this out today!
