2002 trailblazer-water pump replacement

need somewhat step by step for water pump replacement account apparent need for fan, shroud, etc. removal. thanks

Before doing this yourself, might want to check on parts availability, then head to the local dealer and talk to them. Depending on your mileage they may get some factory repayment and do it really reasonably for you. These water pumps (and the fan clutches) are failing early and I've heard they are backing them. Depends on whether you have a dealer, or "stealer" locally. Most seem to be the latter these days, but wouldn't hurt to try.

tom3-----thanks for your advise. I will try the dealer on this one.
