  Q: How to service and repair the heater control valve on a 4.0L engine with an oil cooler on Ford Explorer Sport Trac?

  A: The initial step in servicing the heater control valve of 4.0L vehicles with oil cooler and no auxiliary climate control requires hoisting the vehicle in NEUTRAL position. Draining the engine coolant is the first step before disconnecting the two inlet and outlet heater hose clamps and the heater control valve vacuum hose. The two steps for removing the heater control valve involve first removing the bolt and then extracting the valve. The coolant hoses require lubrication with plain water for proper installation. The reverse order of uninstallation should be used to install the new valve followed by engine cooling system filling.
