Camshaft Phaser and Sprocket: Installation

WARNING: This page is about a different variant/trim than selected.

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

Position the camshaft in a soft-jawed vise. 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 intake camshaft 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 intake camshaft journals and bearing caps with clean engine oil.

Install the intake camshafts and bearing caps. Tighten the intake camshaft bearing caps in the sequence shown in illustration in 3 stages:
- Stage 1: Tighten the intake camshaft bearing cap bolts until finger-tight.
- Stage 2: Tighten to 7 Nm (62 lb-in).
- Stage 3: Tighten to 16 Nm (142 lb-in).

NOTE: The timing chain must be correctly engaged on the teeth of the crankshaft timing sprocket and the intake camshaft drive gear in order to install the exhaust camshaft drive gear onto the exhaust camshaft.

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 (1.18 in) bolt from the upper front cover timing hole to release the tensioner arm.

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