Alright guys, Im a bit confused...

My low coolant light came on the other day when I started the car. I checked the radiator and reservoir. The radiator was fine with fluid, and the reservoir was only a bit below the full when cool mark. I added a bit more fluid, but did not want to overfill it. I started it and let it ran and the light went off. I figured all was good so off to training I went. about halfway there it flickers on and off the rest of the way. when i leave training, it comes back on and stays on. i pull over and the fluid levels are right where they were after I added fluid. Everything looks fine, but that freaking light wont go off. Any ideas?

Your sensor is probably dirty or bad. My coolant light is always on even if my radiator and resivoir are full, I wouldnt pay attention to it, just always keep an eye on the temp gauge and if it starts overheating Id go ahead, and look to make sure your fluids are full, and if their low then start checking maybe for a leak, but if it keeps coolant full, and the light is on, either unplug the sensor or ignore it.

I'd pull the sensor and clean the prongs.

Good luck.

Thanks guys!

Ill try and take a look at it tomorrow. The temps are staying right where they always have. Guess this gives me more reason to get my autometer gauges installed so I know exactly whats what now!

Yep, clean the prongs, replace the thing, or do what alot do and just unplug it. If you go for the latter make sure to regularly check your coolant!
