Serpentine Belt Inspection
The 2.0 diesel engine is equipped with a stretch‑belt that is used to drive the power‑assisted steering pump. This belt must be
removed to service the serpentine belt. Stretch‑belt service and maintenance procedures differ significantly from those that
apply to standard accessory drive belts. Should the serpentine belt need replacement, consult your Mercury Diesel authorized
repair facility.
1. Inspect the serpentine belt for proper tension and for the following:
• Excessive wear
• Cracks
NOTE: Minor, transverse cracks (across the belt width) may be acceptable. Longitudinal cracks (in the direction of
belt length) that join transverse cracks are not acceptable.
• Fraying
• Glazed surfaces
2. Check the operation of the automatic tensioner and associated components.
a. Position a suitable tool on the automatic tensioner pulley bolt.
