It stays attached, but the impeller wears off and can't move coolant.


Is it metal or plastic? You telling me the fins wear off and all that shit circulates through the entire cooling system? I've never heard of this so please excuse my questions on this.

Hmmm, I'm not sure if it's plastic or not. In the next few weeks I'll be tearing my L9H down, I'll try and sneak a peak inside if I can

No one ever updates after the finish a repair , if anyone searching for the same issue . Water pump has cured all my issues at 123k. Towing my trailer today with the new 45 gallons fuel tank underneath didn't go over over 198 coolant temp . Trans stayed 127 up and down hills to west virginia from pa .
