ACCESSORY DRIVE BELT

PCM engines use a single serpentine belt to drive the
engine water circulation pump, sea-water pump and the
alternator.
Engine must be shut OFF and the ignition key
removed before inspecting the drive belt(s). The
drive belt(s) should be checked periodically for
condition and tension. If the belt(s) shows signs of
cracking, glazing or deterioration, replace with new
belt(s).
DRIVE BELT INSPECTION
Inspect the drive belt for excessive wear, shredding or
missing sections.
Inspect the drive belt for contamination from excessive
dirt, oil, coolant or other substances that may effect the
drive belt operation.
If a problem is found, replace the belt after inspecting the
following items:
• All pulleys and tensioners for signs of
misalignment
• All pulleys and tensioners for signs of rust or
other damage
• Bent pulleys or tight bearings in the engine water
circulation pump, sea-water pump and alternator

1. Note the routing of the belt before removing.
2. Using a 15 mm box wrench or socket, turn the
belt tensioner to relieve the tension on the belt.
Slide the belt off of the pulleys. Release the
tensioner slowly to prevent the tensioner
from snapping against its stop, and possibly
causing damage to the tensioner.
3. Slide the new belt onto the pulleys using the
same routing as noted prior to removal.
4. Compress the belt tensioner, and slide the belt
over the tensioner pulley. Release the tension
slowly to tension the belt.
