Sounds like the w/p is not efficient at low rpm. Had a previous(metal) w/p failure gouged out the crankcase half and caused excessive clearance between the impeller blades and the housing?
Have plastic impeller fragments from a previous failure blocked the system? Try looking in the heat exchanger.[/QUOTE]
The water pump that came out was the original water pump and all of the impellers were perfectly intact. So I can't think that the previous water pump cause any problems. I'm going tobleed the system again with the u view And see if that makes any difference.
