2001 VMAX 200 OVERHEATING

[REWJR]

The water pump impeller was in excellant shape, nothing clogging water passages but no water pressure on the guage and pee hole very little pressure??????

If the water pump impeller, housing and gaskets are ok then check thermostats, pressure control valve to see if closing completly and working properly.

I did replace the temp sensors and cleaned the pressure control valve, then put it in the water and got it hot found the big problem an exhaust leak, somewhere near the upper casin gasket or exhaust gasket so now try to fix that and hopefully this will solve my problems of overheating.
