Replacement Interval Guide
- Vauxhall recommend replacement as follows:
- →95MY – replacement every 54,000 miles or 6 years, whichever occurs first.
- 96-98MY – replacement every 60,000 miles or 6 years, whichever occurs first.
- 98½MY→ – replacement every 80,000 miles.
- The previous use and service history of the vehicle must always be taken into account.
Check For Engine Damage
CAUTION: This engine has been identified as an INTERFERENCE engine in which the possibility of valve-to-piston damage in the event of a timing belt failure is MOST LIKELY to occur. A compression check of all cylinders should be performed before removing the cylinder head.

Special Tools
- None required.
Special Precautions
- Disconnect battery earth lead.
- DO NOT turn crankshaft or camshaft when timing belt removed.
- Remove spark plugs to ease turning engine.
- Turn engine in normal direction of rotation (unless otherwise stated).
- DO NOT turn engine via camshaft or other sprockets.
- Observe all tightening torques.
Removal
- Remove:
- Air filter and hose.
- Upper radiator shroud.
- Lower radiator shroud.
- Cooling fan and viscous coupling.
- Auxiliary drive belt(s).
- Cooling fan pulley.
- PAS pump pulley.
- Auxiliary drive belt tensioner.
- Oil cooler hose.
- Crankshaft pulley bolt [1] .
- Crankshaft pulley [2] .
- Timing belt RH upper cover [3] .
- Timing belt LH upper cover [4] .
- Timing belt lower cover [5] .
- Temporarily fit crankshaft pulley bolt [1] . Turn crankshaft clockwise until timing marks aligned [6] & [7] .
NOTE: Some engines have alternative location for timing marks of camshaft sprockets [7] .
- Early engines with eccentric tensioner pulley:
- Slacken tensioner pulley bolt [10] .
- Turn tensioner clockwise away from belt.
- Lightly tighten bolt.
- Remove:
- Automatic tensioner unit bolts [11] .
- Automatic tensioner unit [12] .
- Timing belt.
Installation
- Ensure timing marks aligned [6] & [7] .
NOTE: DOHC: Due to uneven gear ratio between camshafts and sprocket idler shafts, correct camshaft alignment may have been lost if engine has been overhauled or timing belt was broken.
- Fit timing belt in anti-clockwise direction, starting at crankshaft sprocket. Ensure belt is taut between sprockets on non-tensioned side.
- Ensure marks on belt [8] & [9] aligned with marks on sprockets [6] & [7] .
NOTE: Letters on belt should be readable from front of engine [13] .
- Slowly compress pushrod into tensioner body [12] with a force of approximately 100 kg until holes aligned.
- Retain pushrod with 1,4 mm diameter pin through hole in tensioner body [14] .
- Install automatic tensioner unit to cylinder block. Tighten bolts [11] . Monterey →1998: 19 Nm. Monterey 1999→/Frontera: 25 Nm.
- Early engines with eccentric tensioner pulley:
- Slacken tensioner pulley bolt [10] .
- Turn tensioner anti-clockwise to tension belt.
- Tighten bolt to 42 Nm.
- Remove pin from tensioner body to release pushrod.
- Temporarily fit crankshaft pulley [2] .
- Turn crankshaft slowly two turns clockwise. Ensure timing marks aligned [6] & [7] .
- Check extended length of pushrod is 4,0-6,0 mm [15] .
- If not:
- Slowly compress pushrod into tensioner body [12] with a force of approximately 100 kg until holes aligned.
- Retain pushrod with 1,4 mm diameter pin through hole in tensioner body [14] .
- Install automatic tensioner unit to cylinder block. Tighten bolts [11] . Monterey →1998: 19 Nm. Monterey 1999→/Frontera: 25 Nm.
- Early engines with eccentric tensioner pulley:
- Slacken tensioner pulley bolt [10] .
- Turn tensioner anti-clockwise to tension belt.
- Tighten bolt to 42 Nm.
- Remove pin from tensioner body to release pushrod.
- Temporarily fit crankshaft pulley [2] .
- Turn crankshaft slowly two turns clockwise.
- Check extended length of pushrod is 4,0-6,0 mm [15] .
- Install components in reverse order of removal.
- Tighten crankshaft pulley bolt [1] . Tightening torque: 167 Nm.
