Toothed Belt, Without A Divided Toothed Belt Guard

WARNING: This page is about a different variant/trim than selected.
NOTE:

Vehicles from 01.06 have a new toothed belt guard. Identification: The upper toothed belt guard does not have a cover TOOTHED BELT, WITHOUT A DIVIDED TOOTHED BELT GUARD and the guard is divided in the engine mount bracket area. Toothed belt, with a divided toothed belt guard removing and installing. Refer to TOOTHED BELT, WITH A DIVIDED TOOTHED BELT GUARD .

Special tools and workshop equipment required 

NOTE:

In order to be able to remove the engine mount bracket, the engine must be lifted quite far using the engine support bridge -10-222 A-. To prevent damage to the drive axles from bending significantly, it is necessary to disengage the drive axles from the transmission.

Removing 

-- Remove the engine cover/upper air filter housing. Refer to ENGINE COVER/UPPER AIR FILTER HOUSING .

WARNING:

Fuel system is under pressure.

  • Always wear protective eye-wear and protective clothing to prevent injuries and fuel from coming in contact with your skin.
  • Before loosening line connections, place a cloth around the connection point. Then release pressure by carefully pulling off the line.
  • For safety reasons, interrupt the current supply to the fuel pump, refer to SAFETY PRECAUTIONS before opening the fuel system because the fuel pump is activated by the driver door contact switch.

-- Disconnect the lines -1, 2 and 3-. Press the release buttons.
