Just passed 124,051 miles (appropriate for my 124.051 chassis!).
I only have PO records back to 87745, the only thing I see regarding the water pump is replacement of the water pump pulley at 87745. I do see a little dried coolant on the water pump housing just below the really short 2" hose leading left to the block from the water pump.
Don't know if I'll be able to handle the pump too at this time. I'm gonna study my manuals now!
