heater hose routing
For the heater to work correctly you need coolant to come out the fitting on top of the intake manifold, which is below the thermostat. That is important. That is where the coolant from the engine is hottest and it is available when the thermostat is closed. It goes from the intake through the heater core and back to the fitting on the water pump, which is the suction side of the water pump. That way the coolant can circulate through the heater and the engine with the thermostat closed or open.
I still can not tell where the heater hose on the engine is connected. I have no idea why somebody would connect a heater hose to the radiator like that. Ask yourself, how is the coolant going to flow through the heater with the hoses connected the way they are without being cooled by cold coolant in the radiator? If it can circulate at all when the thermostat is closed.
I'm trying to get a new radiator for the Dart and it seems that it may be an oddball? I understand that on most of these the heater hoses come from the block and return to the water pump. Mine appear to go from around the pump and return to the radiator on the passenger side of the upper tank(see 2nd pic) Any idea's on what to replace this with? Gary is working on it too but I'm a GM convert with my first Mopar and it seems that at some times, sister cars from Mopar were even put together differently!
Nothing personal, but this looks like another hack-up from somebody who did not understand the theory of what they were working on. If it was you, deny everything.
