S08 MAINTENANCE
ALTERNATOR BELT
The engine alternator is driven by a belt through pulleys.
These components must be in good order at all times
in view for the alternator to provide electricity, among
others, to the engine, to the battery, to the engine control
panel.
DANGER !
Stop the engine and remove the key before checking or
servicing the alternator belt.
NOTE !
Always keep a spare replacement belt on-board.
IMPORTANT !
A loosen or damaged belt can result in overheats or lack
of alternator charge. A too tighten belt can damage the
bearings of the water pump and of the alternator.
VISUAL CHECK OF THE ALTERNATOR BELT:
If belt internal wires become visible and frayed, replace
it. Check that belt fits properly in the pulley. Belt is
constantly tensioned by an automatic belt tensioner.
TO REPLACE THE BELT:
1. Stop the engine and remove the key from the panel.
2. Move the tensionner clockwise using a wrench and
slip out the belt from the alternator pulley.
3. Install the new belt. Check that the belt seats nicely
between the flanges of all the pulleys.
4. Make sure that the indicator mark of the tensionner
is within the range A as shown on the above picture.
