It's very expensive and a huge pain to replace!!! It's about $1500 at a dealership to have this done. Some here will tell you they've had it done for less then $800, but that's because they went to a dealer that had ZERO clue what was all involved and didn't know how to quote a job correctly.
I'm sure as hell ain't taking it to a dealer, my regular ole' mechanic will have to do the job, but having the right information beforehand to guide him will certainly make the process easier and cheaper.
That said, WHAT exactly is involved in the water pump replacement?
