REMOVAL & INSTALLATION
2.0L and 2.3L Gasoline Engines
See Figures 1, 2 and 3

-
Rotate the engine so that No. 1 cylinder is at TDC on the
compression stroke. Check that the timing marks are aligned on the
camshaft and crankshaft pulleys. An access plug is provided in the cam
belt cover so that the camshaft timing can be checked without removal of
the cover or any other parts. Set the crankshaft to TDC by aligning the
timing mark on the crank pulley with the TDC mark on the belt cover.
Look through the access hole in the belt cover to make sure that the
timing mark on the cam drive sprocket is lined up with the pointer on
the inner belt cover.
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.
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.
-
Loosen and position the power steering pump mounting bracket and position it aside.
-
Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
-
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.
-
Remove the timing belt.
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.
-
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.
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.
-
Install the crankshaft pulley and belt guide.
-
Install the timing belt cover.
-
Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
-
Position the alternator and drive belts, then adjust and tighten it to specifications.
-
Start the engine and check the ignition timing. Adjust the timing, if necessary.
