I'm thinking the water pump is the prime suspect and the radiator is an accomplice.

I think I'll start a new thread from this point forward with any new information related to the radiator or pump.

If anybody has more pictures of a new water pump impeller, or can definitively tell me what's what with my impeller, please post the pics and let me know the straight dope.
