Happened to me too. Water Pump belt was slipping and it only overheated at high RPM's. Russ

It may go to 200 deg F on the gauge Once we hit 1000 RPM or more it quickly drops down to steady 190 degree range where it has always been. I changed the impeller and installed a new raw water pump, but it didn't help Next I was thinking checking the heat xchanger (once I remove the end- cap, will I need new seals?) or replacing the thermostat. Is it easy to replace a thermostat and could that caiuse the engine to run warm at idle? The risers/manifolds are 4 years old --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "UnifliteWorld" group.
