I'm new here and may be in the wrong forum. My 2003 DeVille has been losing coolant for some time now and after adding antifreeze I now see a small puddle near the pump housing on the left(driver's) side of the engine. Gasket failure or pump problem? Thanks for your help.

Okay, so none of you have any comment on this. I took my '03 DeVille to my local garage, not the ripster dealer, and for $450 they are replacing the water pump, belt, and a couple hoses. Hopefully that's the end of the problem. Why would a Northstar engine with 48000 miles develop a faulty water pump. I've had two DeVille's before this that I drove over 100000 miles without a problem.

Welcome to the forum, I have moved your thread to the appropriate area. Coolant loss at 48000 miles on a Northstar car is definitely suspicious, however the good news is that you do see an actual leak, and you don't mention any overheating or engine error codes. I would suspect the gasket before the pump itself.
There is plenty of more experienced techs here that should be able to help.
