coolant low ???

[eespidie]

my coolant low light in my 1992 p.a. pops on occasionally... however my coolant is not low. i recently had to change the petcock... and after that used some sealer for a crack in my radiator... do i have a problem ??? or is my light just screwed up ???

thanks

well, if the coolant isnt low, and the light comes on.... then theres a problem with either the sensor or the circuit that lights the light.

If you put sealer in the system , the sealer could have the sensor sticking causeing the light to come on.. flush out the tank and you should be ok.

I will check the sensor and the circuit...

mine does that to.. where is the sensor? i didn't see it on top on the expansion tank...i wanna clean mine to.. if that doesn't help, i pulling the bulb out.. it's useless anyway with a temperature gauge in the car.

i know nothing about bulbs or temperature gauges... but a guy told me if i have wires running to my plastic tank i'll have a sensor there... and he said something about one on the outside of the radiator...??? i just know what i'm told.
