1. Tension roller; 2. Belt pulley crankshaft; 3. Cooling compressor belt pulley (with air conditioning only); 4. Belt pulley of the three-phase current generator; 5. Power steering pump belt pulley; 6. Coolant pump belt pulley
Lengths: 2040 mm and 2140 mm (air conditioned)
1. Support; 2. Stretching sleeve; 3. Tension roller; 4. External bolt E10
All additional engine units are driven by a ribbed V-belt. It is wider than a conventional V-belt and has many ribs on the inside.
The automatic tensioner keeps the V-ribbed belt evenly tensioned for a long time.
The belt must be checked for damage as part of regular maintenance. Depending on the equipment of the car, V-belts have different lengths.
Removing
1. Remove the hydraulic fan clutch.
2. Place the socket wrench for the E10 bolt on the tension roller and loosen the belt (11) turning clockwise.
Installation
1. Check the profile of the belt pulleys and the tensioner for damage and dirt, clean or replace if necessary. At the same time, pay attention to the embossed places for installing the supports of the tensioner and the holes on the belt pulleys.
2. Ribbed V-belts with dirt deposits between the ribs, cracks, fringes and broken ribs must be replaced.
3. Apply the V-belt, starting with the tension roller, according to the numbers in the figure.
4. Release the tension roller (see picture). Marking (IN) should only be in the workspace (A). If this does not happen, then either the belt is of the wrong length, or the tensioner is faulty.
5. Visually check belt fit on belt pulleys.
6. Install the hydraulic fan clutch.
