loosing coolant

[michaelh305]

Hello I have yet another problem.

Well I have been loosing coolant lately. Pulled up to a buddies house today turned off the car went inside and returned to a puddle of coolant in his driveway. I could not see where it is coming from. My light inside the car does come on. I only notice it leaking while the car is off. I dont see coolant on the ground while the car is sitting in the driveway running. I know there are a few things it can be Cracked Expansion tank, bad cap, hoses, Secondary water pump(coolant pump), or seals on the pipe going from either side of the motor. Any help in how to check these would be great. By the way my friend sells Audi's so I called him and he put me on the phone with one his techs and he said it is probably the pump os those seals. But I donkt know. Any input would help.

I had the same issue and it was a cracked expansion tank. I could see the dried coolant on the hoses under the tank. Wouldn't leak while the car ws running but left puddles after sitting.

Hope that helps.
