Instruction. If, during engine repair, metal chips and dust are found in engine oil in large quantities - the source of which is increased wear, for example, due to damage to the connecting rod bearing, then in order to avoid subsequent damage, it is necessary to replace the oil filter in addition to cleaning the lubrication channels. All seating and working surfaces must be lubricated before installation.

Removing the V-ribbed belt
Instructions: To remove the V-ribbed belt, loosen the two tensioners.
Drain coolant by removing hose -2-. Position -1- is ignored.
Unlock the clip and remove the right-hand connector in the direction of travel from the radiator. Depending on the vehicle's equipment, remove the noise insulation or the underride guard. Mark the running direction of the V-ribbed belt. To loosen the V-ribbed belt, turn the tensioning element from above using a SW16 wrench -T10241 -in the -direction of the arrow-.
Secure tensioning element with locking pin -T10060 A-. To loosen the V-ribbed belt, turn the tensioner from below using a SW 16 wrench in -direction of the arrow-.
Secure the tensioning element with a 4 mm Allen key -1-. Remove poly V-belt -2-.
