INSTALLATION
NOTE: The belt routing schematics are published
from the latest information available at the time of
publication. If anything differs between these
schematics and the Belt Routing Label, use the
schematics on Belt Routing Label. This label is
located in the engine compartment.
Belt tension is not adjustable. Belt adjustment is main-
tained by an automatic ( spring load ) belt tensioner.
1. Check condition of all pulleys.
CAUTION: When installing the serpentine acces-
sory drive belt, the belt MUST be routed correctly.
If not, the engine may overheat due to the water
pump rotating in the wrong direction.
2. Install new belt (3). Route the belt around all pul-
leys except the idler pulley. Rotate the tensioner
arm until it contacts its stop position. Route the belt
around the idler and slowly let the tensioner rotate into the belt. Make sure the belt (3) is seated onto all pulleys.
