REPLACE THE MONO VALVE AND SMALL WATER PUMP AND FAN CLUTCH DIY AND HEAD BY PASS SMALL LINE ON FRONT OF HEAD TO BLOCK 5 IN. LINE REMOVE AND CLEAN, YOUR HEATER IS SLOW TO INCREASE HEAT
I haven't done anything with the monovalve or aux pump, I'll remove them and check them.
I thought that when the monovalve was OFF (12v applied to its coil), the coolant was blocked from the aux pump and heater core.
