1991 Trailboss 350L 2x4 Overheating
My fan motor was not working so I thought this was the problem, so I hard wired the motor and it now works, but the bike is still overheating. The fluid is coming out of a small hose located behind the pull start rode. I think that might be the water pumb assembly. Does anyone know what might be wrong now. Thanks, Bob

Sounds like w/p seals and bearing out,allowing coolant into counter balancer cavity and pumping out vent tube.

Better if you have a manual as there are critical items such as not blocking oil hole in water pump housing when installing seals and bearing,plus not one of my more pleasant jobs to do! BUT dont let me discourage you, just takes a little time to do. Recoil,stator,inner cover has to come off to access w/pump.
