Tensioner, Lower

The servicing process of the right-hand hydraulic timing chain tensioner requires starting with hydraulic chain tensioner removal. When installing this component keep its torque at 44 Nm (32 ft. lbs.). Start by uninstalling the current washer which should later be disposed of. Follow the opposite installation procedure while putting in a fresh hydraulic tensioner washer.

The repair process for servicing the timing chain tensioner begins with removing parts according to the illustration and table that shows the right-hand side hydraulic chain tensioner. You should reverse the removal steps during installation to achieve correct reassembly.

The IService process for timing chain tensioner begins by taking out the RH hydraulic chain tensioner. Apply a torque of 44 Nm when installing the fresh tensioner. Apply clean engine oil to the new O-ring seal before installation while disposing the worn-out O-ring seal. End the installation process by doing the opposite of what was done for removal.

The procedure for servicing the timing chain tensioner starts with removing the RH hydraulic chain tensioner. You should tighten the new tensioner to 44 Nm (32 lb-ft) during installation. Engine oil must become clean before using it to lubricate new O-ring seals during application and all old seals need disposal. The service process concludes with a reverse order of the removal procedures.

Before starting to service or repair the timing chain tensioner always position the vehicle in NEUTRAL on a hoist. First remove the engine front cover and proceed to detach the crankshaft sensor ring before disconnecting the 8 ignition coil electrical connectors. Then uninstall the bolts alongside the ignition coils. Clear away any well debris inside the 8 spark plugs by using compressed air during removal. Set the camshaft lobe to an upper position before inserting the Valve Spring Compressor Spacer as a protective shielding for valve stem seals. Start by marking each component for its original position to prevent engine harm before putting the Valve Spring Compressor to work in removing the camshaft roller followers. Set the keyway of the crankshaft at 12 o'clock before removing all parts of the timing chain tensioning system including bolts, tensioners, tensioner arms alongside both timing chains and crankshaft sprocket. Uninstall the timing chain guides through the removal of their bolts and guides. Mount the Camshaft Position Aligner while you detach the camshaft gear bolt. Workers should squeeze each timing chain tensioner plunger into a vise before they hold back the ratchet mechanism with a small screwdriver then lock it using a paper clip. The sealing bead of non-ratcheting tensioners should be checked for integrity before deciding on replacement. Place two Hydraulic Chain Tensioner Retaining Clips onto the tensioner plungers before compression. The visible colored links should be marked for timing if they become invisible to the eye. You should install camshaft sprockets using new bolts which require a two-step tightening procedure starting at 40 Nm (30 lb-ft) and continuing with an additional 90 degrees rotation. Position the crankshaft using the Crankshaft Holding Tool at Top Dead Center (TDC) before you install the crankshaft sprocket whereas its flange faces forward. Tighten both timing chain guides to 10 Nm (89 lb-in) after proper positioning. Hold the RH camshaft sprocket at 11 o'clock marking as the position while positioning the LH sprocket at the 12 o'clock position. The colored links of the LH timing chain should point toward the timing mark at the crankshaft sprocket before installation of the chain followed by its tensioner arm and tensioner with 25 Nm (18 lb-ft) torque setting. The paper clip on the LH tensioner needs to be extracted. For the RH timing chain follow the same installation procedure with correct alignment before final tightening. Before inserting the Valve Spring Compressor Spacer check that the colored chain links match the sprocket dots then direct the camshaft to the UP position before attachment. Apply clean engine oil to the camshaft roller followers before placing them correctly and installing the 8 spark plugs which you should tighten to 18 Nm (159 lb-in). Drill the 8 ignition coils into their positions by tightening all bolts to 6 Nm (53 lb-in). After that, reinstall ignition coil electrical connectors and place the crankshaft sensor ring on top of the engine front cover.

Service of the hydraulic timing chain tensioner on the left-hand side starts with removing the hydraulic chain tensioner. Follow up installation of the tensioner by tightening it to 44 Nm (32 lb-ft). Clean engine oil should be used for lubricating the new O-ring seal during its installation process. Reinstall the parts while following the reverse steps of removal and discard the old O-ring seal before installation.

Beginning the service on the left-hand hydraulic timing chain tensioner requires removing the hydraulic chain tensioner. Secure the installation of the hydraulic timing chain tensioner with 44 Nm (32 ft. lbs. torque. The following step involves removing along with disposing of the present washer piece. Follow the installation procedures to reverse removal steps by using a new hydraulic chain tensioner washer.
