Does anyone have any diagrams on how to route the heater hose in the engine bay? I recently swaped a four core radiator in and it has an extra nipple for a heater hose. I also am putting in a new engine and need to decide where the outlet should be on the manifold or water pump or should I have one go to the radiator and one go from the top of the pump to the manifold and then from the manifold to the heater box?
