In-Vehicle Repair: Camshafts: Installation

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If new parts are installed, transfer the reference marks made during disassembly to the new parts.

If necessary, position the camshaft in a soft-jawed vise and install the camshaft phaser and sprocket and the bolt.
- Align the reference marks on the camshaft phaser and sprocket and the camshaft. Tighten the bolt to 72 Nm (53 lb-ft).

NOTE: Install the camshafts with the alignment slots in the camshafts lined up so the Camshaft Alignment Plate can be installed without rotating the camshafts. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the removal procedure. Rotating the camshafts when the timing chain is removed, or installing the camshafts 180 degrees out of position can cause severe damage to the valves and pistons.

NOTE: Lubricate the camshaft journals and bearing caps with clean engine oil.

Install the camshafts and bearing caps in their original location and orientation. Tighten the bearing caps in the sequence shown in illustration in 3 stages:
- Stage 1: Tighten the camshaft bearing cap bolts one turn at a time, until finger-tight.
- Stage 2: Tighten to 7 Nm (62 lb-in).
- Stage 3: Tighten to 16 Nm (142 lb-in).

Position the exhaust camshaft drive gear in the timing chain and install the gear and bolt on the exhaust camshaft.
- Hand-tighten the bolt.

NOTE: Releasing the tensioner arm will remove the slack from the timing chain.

Remove the M6 x 30 mm bolt from the upper front cover timing hole to release the tensioner arm.

NOTE: The Camshaft Alignment Plate 303-465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
