Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing
belt to jump time, due to the arrangement of the belt tensioner.
Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water
pump pulley bolts. 2.
CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are
quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless
it is contaminated or several years old.
Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water
pump pulley. 3.
Loosen and position the power steering pump mounting bracket and position it aside. 4.
Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft
pulley and belt guide. 5.
Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P−6254−A
or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt.
Tighten the adjustment bolt to lock the tensioner in the retracted position. 6.
Remove the timing belt. 7.
To install:
Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and
camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the
pulleys. Be careful not to rotate the pulleys when installing the belt. 8.
Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring
does not have enough tension to move the roller against the belt (belt hangs loose), it might be
necessary to manually push the roller against the belt and tighten the bolt. 9.
The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.
Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the
slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the
necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks
are still in alignment when No. 1 cylinder is again at TDC/compression. 10.
Install the crankshaft pulley and belt guide. 11.
Install the timing belt cover. 12.
Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the
cooling system. 13.
Position the alternator and drive belts, then adjust and tighten it to specifications. 14.
Start the engine and check the ignition timing. Adjust the timing, if necessary. 15.
