My 97 GTP has the Low Coolant Light on all the time. I flushed and filled it to the factory specs. Still no help. Ever so often it will go off for like a couple mins then it is right back on. Is it the sensor or what? Thanks for the help.

more than likely is the level sensor on the radiator

My money's on a faulty sensor. The coolant sensors are prone to failure.

My 98 had a Coolant light on at random, replaced sensor and it still did it sometimes. never low never ran hot never leaked or nothing. i eventually ignored it and made sure to check it like you normal should and make sure its all there.

Okay, I know this is an OLD thread, but figured better to add to this one than to start another... I am having the "low coolant light" problem, just started yesterday and after thoroughly checking system and confirming that no, I don't have low coolant. How difficult/expensive is the sensor replacement? And where abouts in the coolant system is the sensor placed?

Wow I'm not kidding.. I had the same problem before my water pump failed and was told it was a sensor problem. I made sure the coolant was full and it always showed full in the radiator as well as as the overflow tank. Guess what.. it hasn't done it again since I had the cooling system properly flushed. There's probably air pockets in the cooling system (or might be caused by sludge build-up on the sensor itself) from Dexcool related problems. Feel free to read this thread about a recent coolant flush.
