Auxiliary component belts

AUXILIARY COMPONENT BELTS

1. Conditioner compressor drive belt
2. Power steering drive belt
3. Alternator - water pump drive belt

NOTE: When checking the belt tension, check that the belts are intact, and that they are free of:

• cuts
• cracks
• material surface wear (smooth and shiny)
• dry or stiff parts (lack of adherence).

In the event of one of the above defects, change the belt.

The contact of the belts with oil or solvents can damage the elasticity of the actual belt rubber and reduce its adherence.
