Instruction: If, during engine repair, large amounts of metal chips and wear products are found in the engine oil - the source of which is increased wear, for example, due to damage to the connecting rod bearing, then in order to avoid subsequent damage, in addition to thorough cleaning of the lubrication channels, replace the oil filter. Lubricate all support and work surfaces before assembly work. For assembly work, the engine must be mounted on the engine and gearbox bracket -VAS 6095-.

Removal and installation of poly V-belt
Instructions: To remove the V-ribbed belt, loosen 2 tensioners.
Drain the coolant, to do this remove the hose -2-.
Position -1- should not be taken into account. 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 16 mm wrench -T10241- in -direction of arrow-.
Secure tensioning element with locking pin -T10060 A-. To loosen the V-ribbed belt, turn the tensioning element from below using a 16 wrench in -direction of the arrow-,
Secure the tensioning element with a 4 mm Allen key -1-. Remove poly V-belt -2-.
