I replaced head gaskes, water pump, thermostat, hoses and radiator cap. Had radiator flushed out. ar runs smooth after inital warm up, but then goes into overheating and no heat comes in the passenger compartment. Haven't verified fan operation or not. Is there a test that I can perform on this? Additionally the left heater hose toward the front of the engine is connected to the forward water pump inlet tube, the other water pump connection is going to the intake manifold.. I had labeled them but tagging had worn off for their location. Is this correct?
