On a 97' vmax 600 twin which way does the coolant flow? The belt for the water pump is working so i think its pumping. Where could the coolant possibly be plugged or could there be air in the system somewhere? If so how do you bleed it?
the coolant should exit the engine through the cylinder head, to bleed the system you may have to raise the front of the sled higher than the rear bumper where the heat exchanger is.Some models even had a bleeder in the rear exchanger.Take the highest point in the cooling system and crack it open and let the air escape there,it may take a couple times but that should do it.If the sled continues to overheat check the t stat by putting it in boiling water to see if it functions.if everything is working you should feel heat in the rear heat exchanger after a few minutes of idling.
