Harper Posted June 26, 2010 Share Posted June 26, 2010 Was it overheating prior to the work, or did you do the work because of the pump seal was leaking fluid, or what? Link to comment Share on other sites More sharing options...

October_V Posted June 26, 2010 Share Posted June 26, 2010 Does it have the overheat light or temp gauge, could it be the sending unit? I changed mine from a light to the full gauges, got a cheap sending unit from a chain parts store instead of the dealer and mine reads in the red all the time.
