Heater Mod, which valve?
I am looking at doing the AC heater mod. I have a valve from a newer F250 that only shuts off the supply line to the heater core. I noticed that most guys have gone with the Ford Ranger style valve that allows the coolant to return to the in line of the waterpump. Is the single style okay to run on the Powerstroke or do I need to get the style with the return. I noticed on Dieselsite the one they sell is the single valve style but I was worried this might restrict coolant flow from the head. Any thoughts on this would be helpful.
