8.1L ACCESSORY DRIVE BELT
The PCM 8.1L engine uses a single serpentine belt
to drive the engine water circulation pump and the
alternator. The sea-water pump is mounted onto the
crankshaft pulley and is driven directly by the crankshaft.
ENGINE MAINTENANCE - 11
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
CAUTION
The replacement of the drive belt requires the
removal of the inlet hose from the sea-water pump.
With the hose removed, it is possible for water to
enter the bilge of the boat, and possibly sink it.
ALWAYS plug the inlet hose securely to prevent this
possibility from occurring.
DRIVE BELT REPLACEMENT (8.1L)
1. Remove the inlet and outlet hoses from the sea-
water pump, being careful not to allow the hose
clamps to fall into the bilge.
2. Remove the bolt and washers that attach the
sea-water pump to the bracket, being careful not
to allow the bolt and washers to fall into the bilge.
3. Loosen the bolts that attach the bracket to the
engine block until a gap, large enough to pass
the belt through, is created.
4. Note the routing of the belt before removing.
