Does anybody have a diagram showing the correct routing of the heater hoses from the egine/radiator to the heater core. I do have the rear heater also. Looking in the repair manual it looks like the one that is connected to the radiator comes from the right hand side of the core and the one from the thermostat housing comes from the left side. Mine are hooked up ackwards from that and the heater is not working. 1995 C2500 Suburban. Thanks in advance.
