AUTION

!

If the screw is not duly tightened, it can come undone, which can result in the oil-

pump not being operated and the distribution being disrupted, thus causing serious
damage to the engine.

-the intake and exhaust collectors: the screws are tightened at 2.5 daNm;
-the belt(s) of accessories: the same method as that for the distribution belt is used.

The stretching values are:

* alternator belt

263+/-10Hz

* Air-Comditioning (A.C) compressor belt

222+/-10Hz.
