Emergency repairs
NOTE: The tensioner can be temporarily blocked with a 4- to 5-mm thick
pin (bore); see the arrow in the illustration.
This facilitates removal and installation of the poly-V-belt.
5. Slacken the poly-V-belt so that it can be removed from the pulleys.
6. Allow the automatic belt tensioner to spring carefully back to the stop, if it has not
been temporarily blocked.
7. Remove the poly-V-belt through the
opening at the guide ring. Hang the
poly-V-belt over a fan blade. Rotate
the fan and hang the poly-V-belt
over it. Repeat this for the entire fan
and then remove the poly-V-belt.
8. Inspect the pulleys for damage, rust
and grease deposits.
9. Pull the new poly-V-belt over the
fan.
10. Fit the poly-V-belt over as many
pulleys as possible.
11. Tension the automatic belt
tensioner (if it has not been
temporarily blocked) using a 17 mm
ring spanner and place the poly-V-
belt over the last pulleys. Allow the
automatic belt tensioner to spring
carefully back against the new poly-
V-belt.
12. If applicable, remove the locking
pin.
The locking pin can be removed by
moving the tensioning roller against
the spring tension.
13. Check that the poly-V-belt falls into all grooves of all the belt pulleys.
14. If applicable, fit the electric fan clutch connector and connect the wiring, making
sure that it is clear of moving parts.
15. Fit the front engine encapsulation.
16. Connect the earth cable to the battery.
