2. Remove the right engine splash guard (see "Removal and installation mudguards and engine crankcase protection").
3. Check the belt tension using the "rule of thumb": press on the belt branch with your thumb and determine the deflection with a ruler. According to this universal rule, if the distance between the pulley centers is from 180 to 280 mm, the deflection should be approximately 6 mm.
4. If the belt is not tensioned, then depending on the configuration, it is necessary to adjust the belt tension or replace the automatic tensioner (see "Replacement of auxiliary drive belts").
5. Install the parts in the reverse order of removal.
