WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.

With the vehicle in NEUTRAL, position it on a hoist. REFER to JACKING AND LIFTING .
Remove the valve tappets. Refer to VALVE TAPPETS .

NOTE: Use compressed air at 7 bar (101 psi) to 10 bar (145 psi). Do not disconnect the compressed air from the cylinder until the valve spring, valve spring retainer and valve collet is installed. Any loss of air pressure will allow the valve to fall into the cylinder.

Connect a compressed air supply to the cylinder that is being serviced.
NOTE: Place all parts in order to one side.

Apply compressed air to the cylinder and remove the valve spring.
