Photos of that strange water pump.

[R STARR]

Hey ya folks here are a few photos of the water pump that I had installed on my 2002 GTP, Has anyone seen this
before?
I have no idea what the "R" is for stamped on one of the blades? Maybe for re-manufactured? Could a pump just have corroded away down to this?

Your water pump veins are destroyed. Im amazed more people dont see this when they are changed. GM actually redesigned the Water Pumps in the later years
