Timing Drive Components: Installation

Install the LH and RH camshafts.
- Lubricate the camshaft and camshaft journals with clean engine oil prior to installation.

NOTE: LH shown, RH similar.

Install the LH and RH camshaft bearing caps in their original locations.
- Lubricate the camshaft bearing caps with clean engine oil.
- Position the front camshaft bearing cap.
- Position the remaining camshaft bearing caps.
- Install the bolts loosely.
- Tighten to 10 N.m (89 lb-in) in the sequence shown in Fig 1.

Install the VCT phaser sprockets and new VCT phaser sprocket bolts finger tight.

CAUTION:

Damage to the camshaft phaser sprocket assembly will occur if mishandled or used as a lifting or leveraging device.
Only use hand tools to remove the camshaft phaser sprocket assembly or damage may occur to the camshaft or camshaft phaser sprocket.

NOTE: LH shown, RH similar.

Using the special tool, tighten the LH and RH camshaft phaser sprocket bolts in 2 stages.
- Stage 1: Tighten to 40 N.m (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees.

CAUTION:

Timing chain procedures must be followed exactly or damage to valves and pistons will result.
Prior to installation, inspect the tensioner-sealing bead for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner or engine damage may occur.

Position the timing chain on the VCT phaser sprocket with the timing mark positioned between the 2 copper (marked) chain links.

NOTE: The LH timing chain tensioner arm has a bump near the dowel hole for identification.

Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner and bolts.
- Tighten to 25 N.m (18 lb-ft).

CAUTION: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into the original locations. Failure to follow these instructions may result in engine damage.

CAUTION: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed. For additional information, refer to Cylinder Head .

NOTE: It may be necessary to push the valve down while compressing the spring.

Using the special tool, install all of the camshaft roller followers.
- Lubricate the camshaft roller followers with clean engine oil prior to installation.
