I'm half way through replacing my water pump. I figured 12 years is probably pushing it. It's not that hard to take off with the car on jack stands. I pulled it out through the opening in the passenger compartment.
What I found was that the bearing feels nice and tight, no play at all, but it looks like the little finger of the gasket was bent into the impeller and scraped away the outer edges of the blades. I thought this was interesting enough to share.
Don't freak out that my coolant is green. I put in an additive that turned the pink to green so that I could track down leaks with a black light.
Scraped Blades
Bent Gasket, I didn't bent the finger out, it was like that
New water pump
Question: the idler pullys has a slight bit of rock to them. They don't grind or squeak at all. How much play is in a new idler?
