Ok, so I know there is alot about this problem on the fourm, only thing is I have tried most of the recomended fixes. My coolent light came on so I pulled over and checked the levels everything was ok. I then noticed that the nipel on the AST was broken. I bought and Installed my new AST, then burped the system. I also checked the wires to the senser and there are no leaks anywere. I have ran the car up to temp then burp the system 4 times now. Light is still on, dont know were to go from here. Getting pissed!

 

hmm. so you checked the coolant sensor... and the buzzer just goes and goes??? does the system pressurize?

 

you may have air in the coolant line causing it to go off like that

 

does it stay on even when filling the cooling system with the car on and radiator cap off?

 

jus a quick question, wen u put the key to on, the coolant lights suppose to come on, but is it suppose to buzz too or not?

 

its not supposed to buzz, if it buzz's for a minute and goes off its possible that your low and when the thermostat opens it goes off.

 

You may simply have a bad sensor. Had one that came with a new remand motor. Drove me nuts trying to figure out what was wrong. I finally swapped in my old sensor and the problem was solved.

 

yea i suppose its juppose to come on for a couple secs only to let me know its working but it shouldnt buzz, i jus gotta replace the damn thing

 

screw drive and a couple hard whacks with a hammer will take care of that.

 

Ok, figured it out, I was under there checking things out and my coolent level sensor wire was, broken in two but I it was blocked by the intercoller piping, pulled the piping off and discovered the problem. Fixed the wire and the light and buzzer has stoped, this was are real pain in the ***. Thanks for all the trouble shooting. My car has some seriously shity wiring.
