Low Coolant Light

I reciently noticed my low coolant light was fading on and off.. I decided it had been forever since I had Flushed and changed my coolant, so I did that.. Now the Low Coolant light is still fading on and off. I have checked the levels several times and everything is fine. Ive also bled the system and there is no air that i can find.. Any ideas???

Re: Low Coolant Light

The sensor in the radiator is bad. Everyone has that problem.

Re: Low Coolant Light

Yeah, after about 5 times of checking to make absolutely sure it wasn't really low, I finally just unplugged the sensor.

Re: Low Coolant Light

It's a low cost sensor, just replace it and have the protection of the sensor function.

Re: Low Coolant Light

just an FYI, the sensors are pieces of crap (like someone said earlier) mine did that a long time ago and after checking it a couple times i just unplugged it. From then on out i just made sure i checked it everytime i washed the car (same time i check all fluid levels).......so i wasnt worried about it, but i did just now replace it. (after a year and half or 2 years without it i believe....haha)

I think i got mine for $30 shipped from jason chromer. for how cheap they are i would just go ahead and replace it, but i am **** about things on the car. So ya know

But b4 you do unplug it MAKE sure you dont have a tear or a spot in one of the coolant hoses that has dry rotted. That would be a huge problem.

Re: Low Coolant Light

Was happening to me, then I overheated and blew a headgasket and warped a head. Always be very wary about your coolant.

Re: Low Coolant Light

Hmm you guys are spoiled by modern technology.
My sensor went bad and turned the lite on so I pulled the bulb out of the cluster.
My feeling is if my old musclecars didn,t have it then my new musclecar don,t need it either.
No airbags, no 4 speed electronically controlled transmission, no coolant level sensor.
I cheat sometimes though.......I am keeping the fuel injection.
