Description
Suitable for Mercedes 1.5, 1.7 and 2.0 (M 266.920 /.940 /.960 /.980) petrol engines with start/stop system.
Installed in, e.g. Mercedes A-Class (W169) and B-Class (W245), etc.
Required when tensioning and releasing the hydraulic V-ribbed belt tensioner, e.g. when removing and installing the clamping device or when replacing the V-ribbed belt.
Tensioning without the appropriate tensioning tool can damage the expensive tensioning device, thereby creating a high risk of injury from parts flying around.
Important note: The tensioning process must be carried out very slowly up to the stop (at least 20 seconds), otherwise the tensioning device may be damaged.
