| CAUTION | This application is an interference engine. Do not rotate camshaft or crankshaft when timing belt is removed, or engine damage may occur. |
- Remove all accessory drive belts. Remove pulleys from crankshaft and water pump.
- Remove timing belt covers and gaskets, noting bolt length and location. Rotate crankshaft clockwise to align timing marks on crankshaft and camshaft sprockets. (Scheme 1)and (Scheme 2).
- If reusing old belt, place mark on belt to indicate direction of belt rotation. Move tensioner inward toward water pump, and temporarily tighten bolt in slotted side of tensioner. Remove timing belt.
Scheme 1
Scheme 2
Inspection
Check timing belt for cracks, cracked or missing teeth, and separating canvas. Inspect timing belt tensioner for worn bearing.
Installation
- Ensure camshaft and crankshaft timing marks are still aligned. (Scheme 1)and (Scheme 2). Move timing belt tensioner toward water pump and tighten bolt.
- Install timing belt on crankshaft and camshaft sprockets. Make sure there is no slack in belt. If reusing old belt, ensure belt is installed in original direction of rotation.
- Apply counterclockwise force on camshaft sprocket to apply tension on tension side of belt. Ensure all timing marks are aligned. (Scheme 1)and (Scheme 2).
- Loosen timing belt tensioner bolts to place tension on timing belt. (Scheme 3) Tighten timing belt tensioner bolts to specification. See «TORQUE SPECIFICATIONS»(ref-156674-S38847313812003072400000).
- Smoothly rotate crankshaft clockwise for one full revolution. Realign crankshaft and camshaft timing marks. Loosen pivot-side bolt, and then slot-side bolt. Tighten slot-side bolt, and then pivot-side bolt to specification. See «TORQUE SPECIFICATIONS»(ref-156674-S38847313812003072400000).
- To check belt tension, hold belt tensioner and timing belt together and apply slight thumb pressure (about 11 lbs.) at center point of belt tensioner. (Scheme 3)
- Ensure belt cog will reach half the width of timing belt tensioner bolt on slot-side of belt tensioner. Install timing belt cover. To install remaining components, reverse removal procedure. Adjust drive belts to proper tension.
