Radiator Warning Light

[91TSiPower]

Whenever my car is turned on and is not warmed up, the radiator warning light stays on until the car is nice and warmed it. This just started happening a few days ago. Nothing seems to be wrong with the car but this stupid light stays on for like 10 minutes or so before it goes away. Any suggestions? Thanks

If you mean the coolant reservoir warning light, which is yellow; you just need to make sure that the overflow bottle is up to the cold line when the engine is cold.
As the engine gets warm and "pressurizes" the cooling system it will let a little coolant out and back in to the bottle, turning off your light. As the engine cools, it will suck coolant back into the engine from the bottle, lowering the coolant level enough; in your case, to trigger the light.

Van is right, you need to add some coolant to your reservoir.

Oh it looked light a train light to me... doesn't it kinda look like a trolley?

Lol! You are right...The first time I saw it, I thought WTF does that mean! I had to look in the owners manual to decipher that "trolley car." Lol
