Coolant temp sensor?

[Jean-François Roldan]

Hi all,

last weekend, the coolant temp light came on beeping in my car. When I got home, I rechecked the level in the subtank and all was fine, I added a little bit in it but there was no reason to trigger the dash light.

Since then, every time I use the car, I get the beeping after a few seconds of running.

Car heats normally, no coolant smell, but the gauge that was not moving a lot before is now totally dead.

Could the dead gauge trigger the dash light, or it is really the sensor at the bottom of the subtank?

It was too cold to check it out yesterday, but today is quite warm...

Thanks all
