I searched, found nothing.

My coolant warning comes on when I hit running temp for about 10 seconds, then shuts off almost every time I drive my car. My tank is full and Ive toped it off many times. Anyone know why?

Im going to change my Thermostat and coolant sensors weds. think that could solve my problem?

Thanks

might have a leak... if you keep having to top it off, you have a leak somewhere, after you turn off your car, listen for pops, crackles, hissing..

 

When you open the filler neck to top it off, is the coolant up near the top or is it empty?

 

Its almost always full. thats why im confused. I dont have to put much in there, like only a few ounces and its full.

That help any?

 

could have a small leak. That coolant level sensor is very sensitive. If it goes a little low then it will sound.

Whats happening probably, is you start your car, some air gets pumped up, displaces the coolant, ur sensor sounds, then the car warms up, the coolant expands, and silences the sensor.

 

thats preaty much what i figured. Well, ill keep checking things. Thanks everyone.

 

Get the system pressure tested. I had a similar problem to yours and bought a mityvac with the universal adapter (a must have piece of equipment) and was able to determine that there was a small leak in the system. I repaired the leak and now I have a full fill tube every time.

 

Did you replace the coolant level sensor itself.
That might me your problem.
