Removal
1. Using a marker or chalk, mark the direction of travel of the accessory drive belt.
2. Remove the cover from the tension roller (A) using lever movements as shown in the figure below.
3. Using a Torx 50 key (B), tilt the tension roller (A) in the direction of the arrow until it stops and remove the poly V-belt, as shown in the figure below.
Note: The tension roller can be locked by installing a suitable pin.
Installation
Note
- Before proceeding with the installation of the poly V-belt, it is necessary to check the strength of the installation of all units (alternator, liquid cooling system pump and air conditioning compressor).
- Check the ease of movement of the tension roller pulleys and guide roller.
- Ensure that the correct direction of movement of the already used poly V-belt is observed.
1. Install the poly V-belt on the pulley and guide roller
2. Fold the tension roller (A) in the direction of the arrow using a Torx 50 key (B) until it stops, and put the poly V-belt on the tension roller, as shown in the figure below
3. Press the cover onto the tension roller (A) shown in the figure below.
4. Start the engine and check the operation of the accessory drive belt.
