To install:

1. Install the camshaft sprockets and tighten the center bolt to 65 ft. lbs. (90 Nm).
2. Align the timing mark of the silent shaft belt sprockets on the crankshaft and silent shaft with the marks on the front case. Wrap the silent shaft belt around the sprockets so there is no slack in the upper span of the belt and the timing marks are still in line.
3. Install the tensioner initially so the actual center of the pulley is above and to the left of the installation bolt.
4. Move the pulley up by hand so the center span of the long side of the belt deflects about ¹ / ₄ in. (6mm).
5. Hold the pulley tightly so it does not rotate when the bolt is tightened. Tighten the bolt to 15 ft. lbs. (20 Nm). If the pulley has moved, the belt will be too tight.
6. Install the timing belt tensioner fully toward the water pump and temporarily tighten the bolts. Place the upper end of the spring against the water pump body. Align the timing marks of the cam, crankshaft and oil pump sprockets with the corresponding marks on the front case or head.

NOTEIf the following steps are not followed exactly, there is a chance that the silent shaft alignment will be 180 degrees off. This will cause a noticeable vibration in the engine and the entire procedure will have to be repeated.

1. Before installing the timing belt, ensure that the left side silent shaft is in the correct position.

NOTEIt is possible to align the timing marks on the camshaft sprocket, crankshaft sprocket and the oil pump sprocket with the left balance shaft out of alignment.

1. With the timing mark on the oil pump pulley aligned with the mark on the front case, check the alignment of the left balance shaft to assure correct shaft timing.

1. Remove the plug located on the left side of the block in the area of the starter.
2. Insert a tool having a shaft diameter of 0.3 in. (8mm) into the hole.
3. With the timing marks still aligned, the tool must be able to go in at least 2 ¹ / ₃ in. (59mm). If it can only go in about 1 in. (25mm), turn the oil pump sprocket one complete revolution.
4. Recheck the position of the balance shaft with the timing marks realigned. Leave the tool in place to hold the silent shaft while continuing.

1. Install the belt to the crankshaft sprocket, oil pump sprocket and the camshaft sprocket, in that order. While doing so, be sure there is no slack between the sprockets except where the tensioner will take it up when released.
2. Recheck the timing marks' alignment.
3. If all are aligned, loosen the tensioner mounting bolt, and allow the tensioner to apply tension to the belt.
4. Remove the tool that is holding the silent shaft in place and turn the crankshaft clockwise a distance equal to two teeth of the camshaft sprocket. This will allow the tensioner to automatically tension the belt the proper amount.

WARNINGDo not manually apply pressure to the tensioner. This will overtighten the belt and will cause a howling noise.

1. First tighten the lower mounting bolt and then tighten the upper spacer bolt.

WARNING If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.

1. To verify that belt tension is correct, check that the deflection of the longest span (between the camshaft and oil pump sprockets) is ¹ / ₂ in. (13mm).
2. Install the lower timing belt cover. Be sure the packing is properly positioned in the inner grooves of the covers when installing.
3. Install the water pump pulley and the crankshaft pulley(s).
4. Install the upper front timing belt cover.
5. Install the power steering pump, alternator, air conditioning compressor, tension pulley and accompanying brackets, as required.
6. Install the radiator, shroud, fan and accessory drive belts.
7. Install the spark plug wires to the tree on the upper cover.
8. Refill the cooling system.
9. Connect the negative battery cable. Start the engine and check for leaks.
