2. Remove timing belt covers and gaskets, noting bolt lengths and locations. DO NOT rotate engine counterclockwise, as viewed from timing belt side of engine. Remove timing belt tensioner pulley.
3. Rotate engine clockwise to align all timing marks so No. 1 cylinder is at TDC of compression stroke. See Fig. 1 . If reusing belt, place mark on timing belt to indicate direction of belt rotation. Remove timing belt.
Inspection
Check belt teeth for cracks, damage, and oil contamination. Inspect all sprockets for damage. Check tensioner pulley and idler pulley for grease leakage and worn bearings. Replace components if damaged.
Installation
1. Ensure camshaft and crankshaft timing marks are still aligned. Outer marks on sprockets should be aligned with rocker cover surface. Verify timing chain timing mark alignment, if necessary. See Fig. 2 . Install timing belt tensioner pulley. Install timing belt. If reusing old belt, ensure belt is installed in original direction of rotation.
2. Loosen timing belt tensioner bolt, allowing tensioner pulley to contact belt. Tighten timing belt tensioner pulley bolt. Rotate crankshaft one turn clockwise. Realign camshaft and crankshaft timing marks. Download File PDF
