– Loosen all bolts again by one turn.
– Apply the torque wrench, -VAS 6583- with a hexagon key SW
10 -item 6- on the coolant pump.
– Using hexagon on coolant pump, preload coolant pump in
clockwise direction to 30 Nm using 10-mm hexagon sock‐
et-6-, extension and torque wrench - VAS 6583- .
– For ease of use, fit torque wrench - VAS 6583- on vertically.
Note
Do not support torque wrench with your other hand.
♦
To ensure the poly V-belt is not over-tensioned, do not »push
♦
the torque wrench again« after the specified torque has been
achieved.
Have a second mechanic tighten securing bolts -2-, -1- and
♦
-5- to specified torque, while your are keeping the torque

• By tightening securing bolts -2-, -1- and -5- to specified torque,
the desired belt tension is reached.
• After securing bolts have been tightened initially, torque
wrench - VAS 6583- can be removed.
– Then tighten the securing bolts in stage »4«.
