During a timing belt servicing, refer to the following service procedure for details.
Note: To achieve proper timing belt tension, the camshaft sprocket
bolts should be loosened enough to permit the sprockets to turn freely
on the camshafts. With cam sprocket bolts loosened and cylinder #1 at
top dead center (TDC), crankshaft must be rotated to TDC in clockwise
direction (install camshaft alignment tool in the camshaft slots).
1) Back out the tensioner bolt four (4) full turns and position the
tensioner so the locating tab is at approximately the 4 o’clock
position. Line up the hex key slot in the tensioner adjusting washer
with the pointer that is located behind the pulley (Figure 1).
2) Working counterciockwise from the crank sprocket, install the timing belt.
3) Rotate the tensioner locating tab counterclockwise and insert the locating tab into the slot in the rear timing cover (Figure 2).
4) Position the hex key slot in the tensioner adjusting washer to the 4 o’clock position (Figure 2).
5) Tighten the attaching bolt enough to seat the tensioner firmly
against the rear timing cover, but still allow the tensioner adjusting
washer to be rotated using a 6mm hex key (Figure 2).
6) Using the hex key, rotate the adjusting washer counterclockwise
until the notch in the pointer is centered over the index line on the
locating tab (the pointer will move in a clockwise direction during
adjustment) (Figure 3).
7) While holding the adjusting washer in position, torque the attaching bolt to 18±2 ft.lbs. (25 ± 3 Nm) (Figure 4).
Note: If the pointer does not remain centered over the index line
during final tightening, loosen the bolt and repeat the procedure
beginning with step 4.
