2. Loosen the toothed belt tensioner mounting bolt 1 or 2 turns.
3. Turn the crankshaft 2 turns clockwise.
4. Tighten the timing belt tensioner mounting bolt.
5. Install the cover you removed earlier.
Belt tension adjustment
1. Check that the belts are not damaged and that they lie correctly in the pulley grooves.
Warning:
- 1. When installing a V-ribbed belt, make sure that its V-ribs are correctly located in the grooves of the pulleys.
- 2. If the belt is noisy or slipping, check for wear, damage or breaks on the pulley contact surface, also check the pulleys for striated wear.
2. Apply a force of 100 N to the middle part of the belt between the pulleys as shown in the figure and measure its deflection.
Normal values:
Note:
- 1. Belt tension should be measured between the marked pulleys.
- 2. When installing a new belt, adjust its tension to an average value «New». Then let the engine run for 5 minutes or more and check the value.
Alternator Drive Belt and Power Steering Pump Adjustment
1. To increase belt tension, slightly loosen the idler pulley mounting nut. Turn the adjusting bolt, which has a left-hand thread, in the direction clockwise and blind, slide the idler pulley.
2. Tighten the mounting nut.
- Tightening torque: Alternator drive idler pulley nut - 39-60 Nm.
Note. Insert the adjusting bolt into the cutout into the recesses.
Check belt deflection. Re-adjust if necessary.
Note. Rotate the crankshaft one or more revolutions before checking.
A/C compressor belt adjustment
1. Loosen bolt A of the idler pulley.
2. Adjust belt deflection with adjusting bolt B.
3. Tighten fixing bolt A.
4. Check belt deflection and readjust if necessary.
Note. Rotate the crankshaft one or more revolutions before checking.
