5.0/5.7L ACCESSORY DRIVE BELT
The Crusader 5.0/5.7L engines use a single serpentine
belt to drive the engine water circulation pump, sea-
water pump and the alternator.
DRIVE BELT REPLACEMENT (5.0/5.7L)
5.0/5.7L SERPENTINE BELT (LH) #: R066028
5.0/5.7L SERPENTINE BELT (RH) #: R066029A
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.

50 hours, or once a year, whichever occurs fi rst. See
Maintenance Schedule.

to loosen the raw water pump housing attaching bolts.
The bolts are secured in the pump by O-rings, and will
not fall out during removal.
