LT500 cooling probs
#1
I have a 89 500 Quadracer that has a cooling problem. While running the cylinder gets hot but the hoses and radiator don't.
While running I pulled off the return hose(head to top of radiator) and water was just dribbling out.
I ran water through the system via a garden hose and the water was coming out good.
I pulled off the side case and inspected the waterpump. The impeller looked perfect and doesn't spin w/o the motor turning over.
So what do you guys think is the problem?...air in the system and the impeller is cavitating?..any ideas on a fix?...Could it be the radiator cap?
The bike has seized before because of this problem and it is getting expensive to fix.
Thanks

By the way, I love this new UBB
