I bought the Gates timing belt kit, and it came with a water pump that wouldn't fit on my 2006 PZEV 2.5i. I used the rest of the components, but they wouldn't take just the pump back. It sells for around $50 if you don't buy the kit. I'm listing it here for $45, shipping included. Here's a picture of the stock one on the left, and the Gates on the right. Obviously, they are not the same, but I suspect it has something to do with the PZEV engine, and the extra cat in the exhaust manifold.
Includes rear metal gasket, and thermostat ring gasket.
