Timing Drive Components: Installation
WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
- Compress each tensioner plunger, using an edge of a vise.
- Using a small screwdriver or pick, push back and hold the ratchet mechanism.
- While holding the ratchet mechanism, push the ratchet arm back into the tensioner housing.
- Install a paper clip into the hole of each tensioner housing to hold the ratchet assembly and plunger in during installation.
- Remove the tensioner from the vise.
- Inspect the RH and LH timing chain tensioners.
- Install new tensioners as necessary.
- Compress each tensioner plunger, using a vise.
- Install a retaining clip on each tensioner to hold the plunger in during installation.
- If the copper links are not visible, mark one link on one end and one link on the other end, and use as timing marks.
- Install the camshaft sprockets and new bolts. Tighten the bolts in 2 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees (1/4 turn).
- Using the special tool, position the crankshaft so the No. 1 cylinder is at top dead center (TDC).
- Install the crankshaft sprocket, making sure the flange faces forward.
- Install the timing chain guide.
- Position the LH timing chain guide.
- Install and tighten the LH bolts to 10 Nm (89 lb-in).
- Position the RH timing chain guide.
- Install and tighten the RH bolts to 10 Nm (89 lb-in).
- Rotate the RH camshaft sprocket until the timing mark is approximately at the 11 o'clock position. Rotate the LH camshaft sprocket until the timing mark is approximately at the 12 o'clock position.
- Position the LH (inner) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.
- Install the LH timing chain on the sprocket, aligning the copper (marked) link with the timing marks on the sprocket.
- Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner.
- Tighten to 25 Nm (18 lb-ft).
- Remove the retaining clip from the LH timing chain tensioner.
- Remove the retaining clip from the LH timing chain tensioner.
- Position the RH (outer) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.
- Install the RH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.
- Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner.
- Tighten to 25 Nm (18 lb-ft).
- Remove the retaining clip from the RH timing chain tensioner.
- Remove the retaining clip from the RH timing chain tensioner.
- Make sure that the copper (marked) chain links are lined up with the dots on the crankshaft sprocket and the camshaft sprockets.
- Rotate the camshaft until the lobe is in the UP position.
- Install the special tool between the valve spring coils to prevent valve stem seal damage.
- Install the camshaft roller followers.
- Install the special tool.
- Compress the valve spring.
- Install the camshaft roller followers in their original locations.
- Install the 8 spark plugs.
- Tighten to 15 Nm (11 lb-ft).
- Install the 8 ignition coils and bolts.
- Tighten to 10 Nm (89 lb-in).
- Connect the 8 ignition coil electrical connectors.
- Install the crankshaft sensor ring on the crankshaft.
- Install the engine front cover. For additional information, refer to ENGINE FRONT COVER .
- If equipped with fire suppression system, repower the system.
Engines with ratcheting timing chain tensioners
CAUTION:
Timing chain procedure must be followed exactly or damage to valves and pistons will result.
CAUTION:
Do not compress the ratchet assembly. This will damage the ratchet assembly.
NOTE:
LH shown, RH similar.
Engines with non-ratcheting timing chain tensioners
CAUTION:
If one or both tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. Any cracks, tears, cuts or separation from the tensioner body or permanent compression of the seal bead, will require replacement of the tensioner.
CAUTION:
The timing chain procedure must be followed exactly or damage to valves and pistons will result.
NOTE:
LH shown, RH similar.
All engines
NOTE:
The LH timing chain tensioner arm has a bump near the dowel hole for identification.
Engines with ratcheting timing chain tensioners
Engines with non-ratcheting timing chain tensioners

NOTE:
Lubricate the camshaft roller followers using clean engine oil.
WARNING:
If equipped with fire suppression system, repower the system. For important safety warnings and procedures, refer to FIRE SUPPRESSION SYSTEM
