Cylinder Head - RH: Material

WARNING: This page is about a different car, the 2010 Lincoln MKZ and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

ITEM SPECIFICATION TABLE

Item	Specification
Motorcraft® SAE 5W-20 Premium Synthetic Blend Motor Oil XO-5W20-QSP (US); Motorcraft® SAE 5W-20 Super Premium Motor Oil CXO-5W20-LSP12 (Canada); or equivalent	WSS-M2C930-A

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.

NOTE: On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.

All vehicles

Install a new gasket, the RH cylinder head and 8 new bolts. Tighten in the sequence shown in illustration below in 5 stages:
- Stage 1: Tighten to 20 Nm (177 lb-in).
- Stage 2: Tighten to 35 Nm (26 lb-ft).
- Stage 3: Tighten 90 degrees.
- Stage 4: Tighten 90 degrees.
- Stage 5: Tighten 90 degrees.

Using new gaskets, install the lower intake manifold and the 10 bolts.
- Tighten in the sequence shown in illustration below to 10 Nm (89 lb-in).
NOTE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

Install new fuel injector O-ring seals.
- Remove the retaining clips and separate the fuel injectors from the fuel rail.
- Remove and discard the O-ring seals.
- Install new O-ring seals and lubricate with clean engine oil.
- Install the fuel injectors and the retaining clips onto the fuel rail.
NOTE: Use O-ring seals that are made of special fuel-resistant material. The use of ordinary O-rings can cause the fuel system to leak. Do not reuse the O-ring seals.

NOTE: The upper and lower O-ring seals are not interchangeable.
