I have a 1993 Clubwagon with the 7.3 diesel. For routine maintenance, I want to back flush the cooling system using the Prestone flush kit. It seems as if there are two inlet and two outlet hoses on this model. The van does have rear heat & A/C. Does it have two inlet hoses? If so, would I have to use two flush tees? If not, which inlet hose should be fitted with the flush kit. Thanks much.

Inlet to what? Heater core, water pump? If you want to flush it I would disconnect each heater core separately and flush them. Reattach, replace all coolant with water and some ford vc9 iron cleaner. Run vehicle get it hot. Then drain the system again plus the block refill and top off.
