Quick Question:

I know this may sound like a silly question, but lately I'm hear'n a metalic sound from the front of the engine and I'm wondering if the water pump has bit the dust....did have an aftermarket temp. gauge....I put a thermastate (SP) in and it quit working I think... I know the engine is supposed to run alittle hot... just wondering if that's what it might be or is it something more serious.
