I have an 01 with the 4.0 and im having a problem when its cold outside the car leaking coolant but i cant see where its coming from and its not a very big leak it only seems to do it when its very cold outside doesnt do it when its hot outside.... any ideas????

 

Have the same problem in my 01. I think my leak may be coming from the radiator. Will take it to the shop to check it out. Heard several complaints about a mystery loss of coolant in the aurora as well as the 2000-2003 caddy seville.

 

i have found that if i dont drive my 95 aurora for 2 days it leaks coolant on the 2nd day. i have to add coolant once every month to month and a half. its like the coolant system has some sort of reversal of coolant after sitting.
