Removal & Installation
- Disconnect the negative battery cable and remove the accessory drive belts, crankshaft pulley and the timing belt cover(s).
- Temporarily reinstall the crankshaft pulley bolt and turn the crankshaft to TDC of No. 1 piston. The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head.
- With the distributor cap removed, the rotor should be pointing toward the No. 1 mark on the rim of the distributor housing. On 8 valve engines, the notch on the crankshaft pulley should align with the dot on the intermediate shaft sprocket.
- Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt.
- Slide the timing belt from the sprockets.
- Check the alignment of the timing marks. On 16 valve engines, the mark on the tooth should align with the mark on the rear belt cover.
- Install the new timing belt and tension the belt so it can be twisted 90 ° at the middle of it's longest section, between the camshaft and intermediate sprockets.
- Recheck the alignment of the timing marks and, if correct, turn the engine 2 full revolutions to return to TDC of No. 1 piston. Recheck belt tension and timing marks. Readjust as required. Torque the tensioner nut to 33 ft. lbs. (45 Nm).
- Install the belt cover and accessory drive belts.
- If the belt is too tight, there will be a growling noise that rises and falls with engine speed.
