• Open end wrench - 13 mm
• Open end wrench - 22 mm
• Wrench attachment - 10
• Wrench attachment - 16
• Allen key - 5mm

Parts and consumables:

• Tension roller
• Guide rollers

Note:

The timing belt should be replaced every 40 thousand kilometers or after 4 years. 

Replace the timing belt if, upon inspection, you find:

1 - traces of oil on any surface of the belt;

2 - traces of wear of the toothed surface, cracks, undercuts, folds and peeling of fabric from rubber;

3 - cracks, folds, depressions or bulges on the outer surface of the belt;

4 - loosening or delamination on the end surfaces of the belt.

Warning:

A belt with traces of engine oil on any of its surfaces must be replaced, as oil quickly destroys rubber. The cause of oil getting on the belt (usually a leakage of the crankshaft and camshaft oil seals) must be eliminated immediately.

Work on a viewing ditch, overpass or lift.
