- Do not utilize timing belt tension when installing or removing the mount bolt of the camshaft timing pulley.
- If there are any defects, as shown in the illustrations, check these points.
a. If there is premature parting,
- Check for proper installation.
- Check the timing cover gasket for damage and proper installation.
b. If the belt teeth are cracked or damaged, check to see if either camshaft is locked.
c. If there is noticeable wear or cracks on the belt face, check to see if there are nicks on the side of the idler pulley lock and water pump.
d. If there is wear or damage on only one side of the belt, check the belt guide and the alignment of each pulley.
e. If there is noticeable wear on the belt teeth,
- Check timing cover for damage.
- Check gasket has been installed correctly.
- Check for foreign material on the pulley teeth.
If necessary, replace the timing belt.
15. INSTALL TIMING BELT
a. Remove any oil or water on the pulleys, and keep them clean.
NOTICE: If adherence of water and/or oil to the timing belt is found, restore the leakage and install a new timing belt. Wipe only the pulleys; do not use any cleansing agent.
b. Inspect the idler pulleys.
1. Check that the idler pulley turns smoothly.
2. Visually check the seal portion of the idler pulley for oil leakage.
