I have a 98 Deville and it leaks coolant after it sits about 4-5 hours after driving. I do not see it leaking around the water pump. and I have checked the top hoses and the bottom hoses (from above). Does anyone else have a suggestion?? Could this still be the water pump?? Thanks for the help!!
Dried Dex leaves a whitish residue. Check the surge tank fittings. They have been known to crack. Also, move the air filter box out of the way and run your fingers along the bottom of the water pump cover. That gasket also is known to leak, enough so that it has been redisigned.
