Replacement Interval Guide

• Vauxhall recommend replacement as follows:
• 95MY – replacement every 36,000 miles or 4 years, whichever occurs first.
• 96MY – replacement every 40,000 miles or 4 years, whichever occurs first.
• 97MY→ – replacement every 40,000 miles or 4 years, whichever occurs first (tensioner pulley must also be replaced).
• Z22XE – guide pulley(s) must also be replaced.
• 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.

Removal

WARNING: Certain engines require modification to tensioner pulley/guide pulleys due to possible failure. Refer to dealer.

1. Mark direction of rotation on auxiliary drive belt with chalk.
2. Turn auxiliary drive belt tensioner clockwise to release tension on belt [1] .
3. Remove auxiliary drive belt.
4. Turn crankshaft clockwise until timing marks aligned [2] .
5. Omega: Reposition pipes and wiring adjacent to timing belt cover.
6. Remove:
   • Engine undershield.
   • Crankshaft pulley bolts [8] .
   • Crankshaft pulley [3] .
   • Timing belt cover.
7. Turn crankshaft clockwise until timing marks aligned [4] , [5] & [6] .
8. Lock camshaft sprockets. Use tool No.KM-832/853.
9. Slacken tensioner bolt [7] .
10. Turn tensioner clockwise until pointer on LH stop. Use Allen key.
    • Type 1 – [10] .
    • Type 2 – [14] .
11. Lightly tighten tensioner bolt.

Installation

1. Ensure lug on water pump aligned with corresponding lug on cylinder block [9] .
2. Ensure timing marks aligned [4] , [5] & [6] .
3. Ensure locking tool located correctly.

   NOTE: Sprockets fitted to inlet camshaft (CA1) and exhaust camshaft (CA2) have similar timing marks. If camshaft sprockets have been removed: Ensure correct dowel location of sprockets on camshafts and timing marks aligned with ‘INTAKE’ [5] and ‘EXHAUST’ [6] marks respectively.

4. Fit timing belt in anti-clockwise direction, starting at crankshaft sprocket. Ensure belt is taut between crankshaft sprocket and exhaust camshaft sprocket (CA2).

   NOTE: Belt adjustment must be carried out when engine is cold.

6. Turn tensioner anti-clockwise until pointer on RH stop.
   • Type 1 – [11] .
   • Type 2 – [15] .
7. Lightly tighten tensioner bolt [7] .
8. Remove locking tool.
9. Turn crankshaft two turns clockwise. Ensure timing marks aligned [4] , [5] & [6] .
10. Slacken tensioner bolt [7] .
11. Turn tensioner clockwise until pointer aligned as follows:
    • Type 1:
    • New belt – ‘V’ notch in bracket [12] .
    • Used belt – LH edge of ‘V’ notch [13] .
    • Type 2:
    • New belt – ‘NEW’ notch in bracket [16] .
    • Used belt – ‘USED’ notch in bracket [17] .
