Re: Water pumps - anybody else?
GM does have a problem with water pump gaskets on certain aluminum water pump / aluminum block engines. Most notable is an issue with the 5.3L V-8 which is found in the Silverado pickups, Chevy Suburbans and GMC Yukons. Gasket failures are extremely common with these. The gaskets went on my 2003 Suburban at around 120K. There were a few drops on coolant on the garage floor in the morning but I was loosing all of it while driving. I replaced the water pump along with the gaskets at the same time since I had everything off. I spent about $160 on a new pump and gaskets, the dealer gets around $600 - $700 for this job.
I wouldn't be surprised if the Cadillacs see the same issue with the aluminum pump / aluminum block combination.
