What does this light mean?
 

The light all the way on the left looks like a raditior or some type of a filter the light goes off when the car warms up.Thanks for the help guys!!!

mine is almost always on. i think its a sensor of some sort for the radiator what is does i dont know. i also would like to find out what its for

Pretty sure that's the engine coolant light, when that reserve fills up it will go off which usually happens after your car has been warm for a little bit. Mine goes on everynow and then but after running it goes off as well.

its the good ole birdcage! you are low on coolant in your radiator.

well thats what i thought so i filled up my radiator with water but it still comes on. maybe it needs coolant? i have a new thermastat so i know its not that

just make sure that your resevoir tank is filled up to the "FULL" line that it has marked on the side. and that when you open your radiator cap, you can see coolant in the radiator. you could possibly have a leak as well. causing you to lose your fluid.
i know right now i have a small leak somewhere. still working on finding it. but its just a miniscule amount every day or so.

thanks guys!!!
