Hi,
REMOVAL & INSTALLATION
2.0L and 2.3L Engines

2.0L and 2.3L engine

1. 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. To remove the timing belt, first rotate the engine and align the
timing marks to TDC
Remove the camshaft gear alignment inspection plug . . .
NOTE: 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. . . . and ensure that the marks are
aligned. If not, rotate the engine one complete turn
Loosen the engine cooling fan attaching 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. . . . then remove the fan from the vehicle
Loosen the accessory drive belt tensioner bolts . . .
. . . then remove the belt (or belts if equipped with air conditioning)
Once the belts are out of the way, remove the water pump pulley . . .
4.Loosen and position the power steering pump mounting bracket and
position it aside.
5. Remove the four timing belt outer cover
retaining bolts and remove the cover. Remove the crankshaft pulley and
belt guide. . . . as well as the tensioner pulley which may be in the
way of the front cover
Remove the upper belt cover retaining screw - 1989 shown, earlier models
use two screws
Remove the lower belt cover retaining screw - 1989 shown, earlier models
use two screws
6. 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. Loosen
and remove the crankshaft pulley retaining bolts . . .
. . . then remove the pulley from the crankshaft
Disengage the plastic lock tabs on the outer timing belt cover . . .
. . . and remove the cover from the engine
Mark the direction of rotation on the old belt, in case you need to
reinstall it
7. Remove the timing belt. Loosen the tensioner pulley adjusting bolt . . .
. . . then loosen the pivot bolt. Rotate the tensioner to relieve the
pressure . . .
. . . and tighten the adjuster bolt then remove the belt from the cam
and crankshaft pulleys
- 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. NOTE: 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.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
