2001 Pontiac Grand Am water pump

This is a very involved job that is best left to the professionals. If you want to attempt it yourself, start by reading through the pages of instructions. You can buy a subscription to an online service manual, but I prefer a paper copy of the manufacturer's service manual. EBay is a good place to find them. Don't look for a Haynes or Chiltons manual. They leave out a lot of stuff, and they only cover things do-it-yourselfers can handle. The water pump procedure might be included, but it's still a pretty big job.
