Timing Components: Testing and Inspection

TIMING BELT INSPECTION





NOTICE:
- Replace every 60,000 miles.
- Do not bend. twist or turn the timing belt inside out.
- Do not allow the timing belt to come into contact with oil, water or steam.
- Do not utilize timing belt tension when installing or removing the mounting bolt of the camshaft timing pulley.

If there are any defects found, check the following points:





1. Premature parting.
- Check the proper installation.
- Check the timing cover gasket for damage and proper installation.





2. If the belt teeth are cracked or damaged, check to see if either camshaft or water pump is locked.





3. 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.





4. If there is wear or damage on only one side of the belt, check the belt guide and the alignment of each pulley.





5. If there is noticeable wear on the belt teeth, check the timing cover for damage, correct gasket installation, and for foreign material on the pulley teeth.

If necessary, replace the timing belt.

Free length: 35.3 mm (1.390 in.)

If the free length is not as specified, replace the tension spring.

2. Measure the tension of the tension spring at the specified installed length.

Installed tension: 58 N (13.0 lbf) at 50.5 mm (1.988 in.)
