My coolant light comes on every so often while I am drving. The water temp doesnt go past half way, so my engine is not getting hot as far as I can tell. I want the damn thing to go off and stay off.. Also I am going to flush my raiator when I get a chance, by putting redline water wetter in it what will that do, and what kind of coolant do you guys recomend?
why is the coolant light on???

could be a slight clog cause a sensor is prolly reading that u ahve no coolant
i used a mix of water and gm syncromesh, and a touch of either purple ice or redline water wetter...of course in my 98 GT

I can't say I've ever heard of using gear oil as coolant??? Or do you mean Dexcool?

The float sensor. Try moving it up and down a little to see if it starts floating again.
If not you need a new tank. I just took mine out though

You might just need to top of your antifreeze. My coolant light is VERY sensitive. If the level is just a little low it will cause it to come on if I park my car on a hill.
My coolant level is where it should be. It comes on when I drive sometimes, and back in the summer when it came on and I had the AC on it would blow out in the floor board on the pass. side and drip water a little bit.. 
I think I am goign to flush the rad. and clean the tank real good in the next couple of weeks when it is nice.. Cause I dont have a garage and I live on a hill
Anymore clues about this problem I have seen other 2000 GT owners post the same question and never answered...

any fix to this yet?
i just got the same light today.
i took the tank out and when i filled it with just water, the white floating thing just stayed on the bottom. i cleaned around that area where the floating thing is cause it was dirty. i took out the sensor on the bottom, but that looked clean.
i put some new coolant in and it looks like the floating thing is floating a little. i didn't buy enough coolant, so it didn't fill up the tank. will buy another bottle of coolant tomorrow.

My light would do this but I think I found my problem the ****ty plastic wire plug that hooks to the sensor outside the tank broke a clip off so it was getting a bad connection. So check the connection.
mine is still on 
i think i need a new resevoir tank. the floaty thing in the tank doesn't float all the way to the top. it stays like in the middle or something. if i move up the floating thing to the top and start the car, the light won't come on, but as i'm driving, the light will come on again. the floating thing will start to float towards the bottom and thats why the light comes on. at least thats what i think

The water that is coming out on the pas. side is condensation from the Ac, not the coolant unless you have a bad heater core.

When I changed the coolant, this happened to me. You might have air in the system, I loosened the coolant reservoir cap and ran the engine for a few mins then filled the coolant all the way up and it went away.

Yep, mine used to come on once in a while and I just topped the coolant off and it never came on again.
