I'm very happy with this part. It was identical to the original part. Much less expensive than going through the dealer, of course. It certainly isn't an "easy fix" but it's a very do-able DIY job to replace a water pump. It was one of those very rewarding fixes because of the dramatic change in engine noise, and coolant leakage.
