Timing Belt Removal, Inspection, and Installation

[SteveSter]

Installation[/b]

1. Place timing belt auto tensioner in a press using a flat washer to prevent damage to the auto tensioner. See fig. 5. Using no more than 2200 lbs. of pressure, compress tensioner rod until the holes in the rod and housing are aligned. Install a .055" (1.4mm) diameter pin through holes in housing and the rod to hold it in place.
2. Install timing belt tensioner on cylinder block with the upper retaining bolt only; do not fully tighten upper bolt.
3. Ensure crankshaft and camshaft timing marks align. See fig.2. Install timing belt on sprockets in order. See fig. 6. Ensure tension exist on belt between crankshaft pulley and camshaft pulleys. While applying pressure on timing belt install No. 1 idler pulley.
4. Push outward at bottom of timing belt tensioner, and install lower retaining bolt in timing belt tensioner. Tighten both timing belt tensioner retaining bolts to spec. See torque specs. Remove pin from timing belt tensioner allowing tension to be applied on the belt.
5. Rotate crankshaft 2 full revolutions clockwise (as viewed from timing belt end of engine) from TDC to TDC. Ensure timing marks on camshaft sprockets and crankshaft sprockets are properly aligned. See fig 2. If timing marks are not aligned, remove and repeat entire timing belt installation procedure.
6. Install right (timing belt side) engine mount. Install timing belt covers using NEW gaskets. Tighten retaining bolts to spec.
7. Install dipstick tube with a new "O" ring. To install remaining components, reverse removal procedure. Tighten fasteners to spec. Adjust drive belts to proper tension.
8. Check crankshaft position sensor air gap. Gap between center of senor and outer edge of rotor tooth should be 0.020-0.059" (0.5-1.5mm). If not check for damaged components. Air gap is not adjustable.
