Removal the engine damper
Removal the rear timing belt cover fastening
Unscrew the fastener (1). Loosen the tension belt nut (4).
Loosening the timing belt tension
Turn the tension roller as far as possible with a screwdriver (1) to the right and tighten the tension roller nut (2).
Installing the suspension
Install the engine mount, tightening (A) to 115 N·m and nut (B) to 90 N·m.
Timing belt wear
Setting the valve timing should usually be done after repair work that involved removing the timing belt or disassembling the engine. When checking the valve timing, all steps must be completed except replacing the timing belt.
Removal
1. Disconnect the negative ground cable from the battery.
Caution! This will erase the contents of electronic memory devices, such as the engine fault memory or the radio code. Before disconnecting the battery, please read subsection 2.11.
2. Raise the vehicle and remove the right front wheel.
3. Remove the lower engine cover in the right wheel arch.
4. Remove the V-belt.
5. Block the engine. To lock the engine, engage 5th gear and have an assistant press the brake pedal. Loosen the crankshaft belt pulley mounting bolts.
6. Remove the crankshaft pulley.
7. Remove the glow plugs.
8. To turn the engine crankshaft, apply the handbrake and set the gearbox to neutral. Using a ratchet and socket, turn the crankshaft from the right wheel arch side.
Caution! Never turn the crankshaft using the camshaft sprocket via the timing belt drive.
9. Loosen the tension roller bolt and use a screwdriver to push the tension roller away from the timing belt until the timing belt tension is released. Retighten the tensioner roller bolt.
10. Remove the right and left timing belt covers.

11. Remove the timing belt. After this, do not turn the gears.
Caution! Before removing, double-check that the mark on the camshaft gear matches the edge of the cylinder head; adjust if necessary.
Caution! If the camshaft needs to be rotated with the timing belt removed, make sure none of the pistons are at TDC. Otherwise, serious damage to the pistons and valves may occur.
12. If it is necessary to turn the camshaft, set all pistons to half their stroke in advance. To do this, use chalk to mark the top of the crankshaft wheel.
13. Before applying the mark, set cylinder 1 to the TDC position. To do this, rotate the crankshaft until the mark (1) on the camshaft gear (2) aligns with the mark on the front plate. Then turn the crankshaft wheel 1/4 turn (90°) left or right. The mark should now be facing left or right.
Installation
Caution! Do not bend or twist the timing belt. Be sure to replace belts that are dirty, damaged or worn. Check that the tension roller moves smoothly and easily.
1. Check the belt wear.
2. Apply the timing belt. When applying the old belt, apply it in accordance with the arrow marked in the direction of rotation.
Caution: Make sure the belt grips the rollers securely and does not sag.
Tension
1. Loosen the tension roller bolt enough to allow the roller to move toward the timing belt under spring force.
2. Turn the crankshaft two turns clockwise until the marks on the camshaft and front plate align. Double check that all the marks match.
3. Tighten the tension roller bolt to 45 Nm.
4. Turn the crankshaft two revolutions in the direction of engine rotation and check the adjustment again.
5. The section of the belt between the water pump and camshaft rollers should deflect by 10.5–12.0 mm under a force of 10 kg (strong finger pressure), if this is not the case, loosen the tension roller bolt and tighten the belt again.
6. Install and tighten the right and left timing belt covers to 10 Nm.
7. Install and secure the engine shock absorber.
8. Install the crankshaft pulley with the washer and tighten the mounting bolts to 30 Nm.
9. Install glow plugs.
10. Install and tension the V-belt.
11. Install the cover in the right wheel arch.
12. Connect the negative ground cable to the battery.
13. If you have a clock, set the time and enter the security code into the radio.
