Removal and Installation

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.

All camshafts

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.

Rotate the crankshaft counterclockwise until the crankshaft dowel pin is in the 9 o'clock position.
NOTE: The crankshaft must remain in the freewheeling position (crankshaft dowel pin at 9 o'clock) until after the camshafts are installed and the valve clearance is checked/adjusted. Do not turn the crankshaft until instructed to do so. Failure to follow this process will result in severe engine damage.

LH camshafts
Position the camshafts onto the LH cylinder head in the neutral position as shown in illustration.
NOTE: The camshafts must remain in the neutral position during installation or engine damage may occur.

NOTE: Coat the camshafts with clean engine oil prior to installation.

Install the 8 camshaft caps and the 16 bolts.
- Tighten in the sequence shown in illustration to 10 Nm (89 lb-in).
NOTE: Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.

RH camshafts
Position the camshafts onto the RH cylinder head in the neutral position as shown in illustration.
NOTE: The camshafts must remain in the neutral position during installation or engine damage may occur.

NOTE: Coat the camshafts with clean engine oil prior to installation.

All camshafts
Using a feeler gauge, confirm that the valve tappet clearances are within specification. If valve tappet clearances are not within specification, the clearance must be adjusted by installing new valve tappet(s) of the correct size. For additional information, refer to VALVE CLEARANCE CHECK .
NOTE: If any components are installed new, the engine valve clearance must be checked/adjusted or engine damage can occur.

NOTE: Use a camshaft sprocket bolt to turn the camshafts.

LH camshafts
Rotate the LH camshafts to the Top Dead Center (TDC) position and install the Camshaft Holding Tool on the flats of the camshafts.
NOTE: Use a camshaft sprocket bolt to turn the camshafts.
