2. Check that the timing marks of the camshaft timing pulleys and timing belt plates at aligned.
If not, turn the crankshaft 1 complete revolution (360°).
3. Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approximately 50°.
NOTICE: If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to
come into contact with each other when you remove the camshaft timing pulley and camshaft, causing damage. So always set the
crankshaft pulley at the correct angle.
c. Alternately loosen the 2 bolts, then remove the bolts, the belt tensioner and dust boot.
d. Using a SST, release the tension between the camshaft timing pulley (RH bank) and crankshaft timing pulley by turning the camshaft timing
pulley (RH bank) counterclockwise slightly.

e. Disconnect the timing belt from the timing belt idler No. 1 and remove the timing belt.
22. INSTALL TIMING BELT
a. Check the timing belt idler No. 1 and No. 2.
1. Visually check the seal portion of the idler pulley for oil leakage.
If leakage is found, replace the idler.
2. Check that the idler turns smoothly.
If necessary, replace the idler.
b. Check the water pump.
1. Visually check the air hole and water hole for coolant leakage.
If leakage is found, replace the water pump and timing belt.
2. Turn the pulley, and check that the water pump bearing moves smoothly .
