How to Replace Valve Cover Gasket in a Ford Explorer

by Contributor

Your Ford Explorer may be reliable for traveling to work, school and running errands, but if the appropriate maintenance isn't performed regularly, your vehicle will start to experience problems. One form of upkeep is to replace the valve cover gasket when the time arises.

Step 1

Remove the air duct from the MAS to the throttle on the driver's side of the vehicle. Remove the throttle, the belt, the AC compressor and the hose around the intake manifold.

Step 2

Remove the wiring from the compressor and the valve cover. Disconnect the vacuum hose on the carbon canister from the throttle. Remove the PCV valve and hose, the power brake vacuum hose and the remaining two hoses that are attached. Remove the bolts and the valve cover.

Step 3

Disconnect and remove the battery. On the passenger side remove the alternator and drain the coolant. Remove the top radiator hose and heater hose. Remove the spark plug leads and the coil module, unplugging the low-voltage connection from the coil. Remove the bolts and the valve cover gasket.

Step 4

Remove the old gasket and clean the seating area with automotive engine cleaner and a brush. Place the new gasket into the gasket seating area. Replace the bolts and tighten them. Be sure not to tighten the bolts too much or the gasket will not fit properly.

Step 5

Replace the valve cover. Reconnect the low voltage connection to the coil, the spark plug leads and the coil module. Reconnect the top radiator hose, the heater hose and the alternator.

Step 6

Reconnect the power brake vacuum hose, the two hoses and the PCV valve and hose. Reconnect vacuum hose on the carbon canister from the throttle and the wiring from the compressor and the valve cover.

Add oil to the engine and start the car. Allow the car to run idle for about 10 to 15 minutes. This will allow for the oil to flow back through the motor, lubricating the parts.


  • Drive the car for a short distance of about 15 to 20 miles before you revert back to your normal driving patterns. This will allow you to check to ensure that you performed the maintenance accurately.
