Timing Belt & Balance Shaft Belt: Inspection

1. Inspect timing belts for damaged teeth and cracking. Ensure belts are not contaminated with oil. Check tensioners for free rotation and grease leakage. Replace components if damaged or if grease leakage exists.
2. Check timing belt auto tensioner for leaks. Hold timing belt auto tensioner upright. Measure rod protrusion above edge of housing. See Fig 1. Length should be .47" (12 mm). Apply 22-44 lbs. (98-196 N) of force to end of rod. If auto tensioner rod moves more than .039" (1 mm), replace the auto tensioner.
