93 RRC heater core question
Does anybody know which hose is the inlet and which hose is the outlet on a 93 RRC heater core? There is one hose which comes out of the back of the water pump and one hose which originates just below the thermostat housing.
I need to back flush my heater core and want to make sure I flush it the right direction. I have spent a couple hours looking on line and can't find it...
Thanks in advance.
