Timing Belt - REMOVAL & INSTALLATION

2.8L SOHC (AFC) V6 Engine

1. Note the radio security code and disconnect the negative battery cable.
2. Place the (hood) lock carrier in the service position. For additional information, please refer to the following topic(s): Body And Trim, Service Position, Front Bumper, Hood Lock Carrier.
3. Remove the engine accessory drive belt. For additional information, please refer to the following topic(s): General Information And Maintenance, Routing Maintenance And Tune-up.
4. Turn the engine by hand to Top Dead Center (TDC) on the firing stroke for cylinder No. 1.

1. Remove the Crankshaft Position (CKP) sensor from the lower left side of the engine block. Make sure the engine is at TDC and install the threaded crankshaft holding pin Tool No. 3242 and lightly tighten.
2. Remove the upper timing belt covers, the crankshaft vibration damper and then the lower timing belt cover.
3. Loosen the camshaft sprocket bolts slightly and use a suitable pulley to release the sprockets from the tapered ends of the camshafts.
4. Loosen the tensioner roller and remove the drive belt.

1. Install the timing belt over the sprockets, then the idler rollers and lastly over the tensioner.
2. Install camshaft alignment tool holder Tool No. 3243 into the camshaft alignment flanges.
3. Check and adjust the cam belt tension such that the upper left portion of the belt between the tensioner and the left cam gear can just be twisted 90° ( 1 / 4 turn).
4. Tighten the cam belt tensioning roller to 33 ft. lbs. (45 Nm), and the camshaft sprocket bolts.
5. The balance of the installation is in reverse order of removal.

1. Note the radio security code and disconnect the negative battery cable.
2. Place the (hood) lock carrier in the service position. For additional information, please refer to the following topic(s): Body And Trim, Service Position, Front Bumper, Hood Lock Carrier.
3. Remove the engine accessory drive belt. For additional information, please refer to the following topic(s): General Information And Maintenance, Routing Maintenance And Tune-up.
4. Turn the engine by hand to Top Dead Center (TDC) on the firing stroke for cylinder No. 1.

1. On the cylinder block near the crankshaft, remove the sealing plug from the lower left side of the engine block. Make sure the engine is at TDC and install the threaded crankshaft holding pin Tool No. 3242 and lightly tighten.
2. Remove the upper timing belt covers, the crankshaft vibration damper and then the lower timing belt cover.
3. Loosen the camshaft sprocket bolts slightly and use a suitable pulley to release the sprockets from the tapered ends of the camshafts.
4. Using a 8mm Allen® wrench, rotate the timing belt tensioner roller clockwise until the tensioner is compressed; then, insert a 2mm spring pin through the tensioner housing and tensioner plunger to secure it in place. When the plunger is secure, release the wrench tension.
5. Remove the damper-to-crankshaft bolts and the damper.

1. Remove the serpentine belt idler and the crankshaft damper guard.
2. Mark the running direction of the timing belt and remove it from the pulleys.

1. Make sure that the camshaft pulleys and the crankshaft pulley are in alignment with TDC of the No. 1 cylinder's compression stroke.
2. Install the timing belt; make sure the timing belt is installed in the correct running direction from which it was removed.
3. Using a 8mm Allen® wrench, rotate the timing belt tensioner roller clockwise until the tensioner is compressed; then, remove the 2mm spring pin from the tensioner housing. Slowly, release the tensioner spring pressure to put pressure on the timing belt.
4. Install the crankshaft damper guard and the serpentine belt idler pulley; torque the idler pulley bolts to 33 ft. lbs. (45 Nm).
5. Install the crankshaft damper and torque the damper-to-crankshaft bolts to 15 ft. lbs. If the damper-to-crankshaft center bolt was removed, torque it to 147 ft. lbs. (200 Nm) plus 180° 1 / 2 turn).
6. Remove the Crankshaft Holder tool No. 3242 and install the sealing plug.
7. Replace the remaining components by reversing the removal procedures.
8. Refill the cooling system and the automatic transaxle. Connect the electrical connectors. Install the negative battery cable last.
9. Test drive the vehicle.
