Hey everyone I have a 2001 deville and I have had it for a year and when I first bought it it was losing coolent and the dealer put a new water pump in. (They said that if any 01 devilles come in losing coolent they are to switch out the water pump) any way now about a year later I started the car in the morning and the coolent light comes on, I check it and it is just barely below the line so I fill it up and it doesn't appear to be losing any fluid now. I have been looking for a leak but have been unable to find anything, no bubbles in the overflow tank no coolent on the ground. Just water I assume from the ac(Passenger side towards the back of the motor.)

It was chilly in the morning if that has anything to do with compressing the coolent.

Ps getting new tires put on that are supposed to ride like a dream. Goodyear Comfortread I will let you know what I think.
