Removal & Installation
- Before servicing the vehicle, refer to the Precautions section.
- Remove all necessary components for access to the timing belt covers.
If equipped with an air bag, be sure to disconnect the negative battery cable and wait at least 90 seconds before proceeding.
- Remove the lower timing belt cover by removing the four bolts.
Remove the No. 2 timing belt cover as follows:
- Remove the bolt and disconnect the engine wire protector from the No. 3 (rear) timing belt cover.
- Disconnect the engine wire protector clamp from the No. 3 timing belt cover.
- Remove the five bolts from the No. 2 timing belt cover.
- Remove the No. 2 cover from the engine.
- Remove the right engine mounting bracket by removing the nut and two bolts.
- Remove the crankshaft timing belt guide.
- Temporarily install the crankshaft pulley bolt.
- Turn the crankshaft and align the crankshaft timing pulley groove with the oil pump alignment mark. Always turn the engine clockwise.
- Ensure the timing mark of the camshaft timing pulleys and rear timing belt covers are aligned. If not, turn the engine over an additional 360 degrees (one revolution).
- Remove the crankshaft pulley bolt.
If the belt is to be reused, align the installation marks on the belt to the marks on the pulleys. If the marks have worn off, make new ones.
- Alternately loosen the two timing belt tensioner bolts. Remove the tensioner and dust boot.
- Remove the timing belt.
- Remove any oil or water from the pulleys.
- Align the front mark of the timing belt with the dot mark of the crankshaft timing pulley.
- Align the installation marks on the timing belt with the timing marks of the camshaft pulleys.
Install the timing belt in the following order:
- Crankshaft pulley.
- Water pump pulley.
- Left camshaft pulley.
- No. 2 idler pulley.
- Right camshaft pulley.
- No. 1 idler pulley.
- Using a press, slowly press the timing belt tensioner until the holes of the pushrod and housing align. Insert a 0.05 in. (1.27mm) hexagonal Allen wrench through the holes to preserve the setting position.
- Install the dust boot to the tensioner.
- Install the tensioner with the two bolts. Alternately tighten the bolts to 20 ft. lbs. (27 Nm). Remove the Allen wrench.
- Turn the crankshaft clockwise and align the crankshaft timing pulley groove with the oil pump alignment mark.
- Ensure the camshaft timing marks align with the timing marks on the rear timing belt cover.
- Install the timing belt guide.
- Install the right engine mounting bracket and tighten the bolts to 21 ft. lbs. (28 Nm).
- Install the upper timing belt cover with the five bolts. Tighten the bolts to 74 inch lbs. (8 Nm).
- Install the engine wire protector clamp to the No. 3 timing belt cover.
- Install the engine wire protector to the No. 3 timing belt cover with the bolt.
- Install the lower timing belt cover by installing the four bolts. Tighten the bolts to 74 inch lbs. (8 Nm).
- Install the remaining components. During installation be sure to tighten the crankshaft pulley bolt to 159 ft. lbs. (215 Nm) and the No. 2 alternator bracket nut to 21 ft. lbs. (28 Nm).
Remove or disconnect the following:
RH front fender apron seal
Remove the timing belt
WARNINGIf the timing belt is disengaged, having the crankshaft pulley set at the wrong angle can cause contact of the piston with the valves, causing damage to the valves. Always set the crankshaft pulley at the correct angle.
NOTEDo NOT reinstall the timing belt tensioner with the plunger extended.
Set the No 1 cylinder to TDC/compression
Remove timing belt tensioner
Remove the timing belt in the following order.
No 1 idler pulley
Inspect the timing belt
NOTEDo not reuse the timing belt if there is evidence of fraying, oil contamination, cracking, tooth damage or wear, or belt distortion. If there is any doubt in the belt condition, replace the belt.
After inspecting the pulleys for wear and checking for oil leaks install the timing belt using the following procedure.
Temporarily install the crankshaft pulley bolt
Install the timing belt tensioner using the following procedure
NOTEKeep the tensioner in an upright position
Slowly depress the push rod and align the hole with the hole in the housing
- Slowly turn the crankshaft 2 revolutions clockwise.
- Check to see that all timing marks are in alignment.
- Remove the crankshaft bolt
- Install the timing belt guide
- The remainder of the installations is the reverse order of removal.
- Start the engine and check for leaks.
