Installing
Installation is the reverse of removal, noting the
following:
- Install V-belt and loosely bolt both halves of belt
pulley to coolant pump.
- Slowly bring belt pulley halves together by
turning coolant pump and tightening bolts for
belt pulley in stages.
While tightening pulley halves, the V-belt must
move outward and sit correctly on belt pulley.
- Tighten bolts to 25 Nm (18 ft lb).
Note:
Adjustment of V-belt tension for coolant pump is
not possible.
- Install ribbed belt and release tension on
tensioner.
- Start engine and check running of belt.
- Check tightening torque of bolts for coolant
pump belt pulley.

Installing (adjust valve timing)
Note:
Use the following procedure to adjust toothed
belt, even for repairs that only require removal
of toothed belt from camshaft gear.
Adjustments can be made on a hot or cold
engine.
CAUTION!
When turning camshaft, crankshaft may not
be at TDC for any cylinder. Valves and/or
piston heads may be damaged.
- Align marking on camshaft gear to marking on cylinder head cover.
- Place toothed belt on crankshaft gear noting direction of rotation.
- Install lower toothed belt cover.
- Using a bolt, secure vibration damper/belt pulley (note locating point).
- Set crankshaft to TDC Cyl. 1 position.
- Place toothed belt on belt tensioner and camshaft gear.
