does any body knows the direction of flow of the coolant on both m42 and m44 cars, like i mean the whole system, im trying to make all my m44 stuff work on the m42 motor but the m42 head doesnt have that plastic fitting at the back of the head so that deletes 2 houses and one of them goes to the heater core so i dont wanna just conected somewhere else and make the flow all messed up
