'84 T25 - Temp warning light

[gmc]

Hi,

My temp gauge works fine, but the warning lights flashes constantly.

I'm new to T25's, so just wondering what the problem is......faulty sensor maybe? If is is, whats the sensor called?

Cheers.

could be the plug on the expansion bottle or bad earth??

Checked the coolant level? Not the expansion bottle just inside the catflap, but the main one in the corner under the engine lid.

If that's right up to the brim, and the expansion bottle is to the mark (with the engine cold), then you'll probably need to take the level sensor out of the main bottle and give it a damn good clean.

I had the same problem, after checking all other things were correct, I found that the connector on top of the bottle was slightly corroded so just undid it and cleaned it with some WD40, Bingo-- Job Done! (for Me anyway) best of luck.
