INSPECT the idler
pulley(s) for
smooth rotation. INSTALL a
new idler
pulley(s) as neces-
sary. TEST the system for
normal operation.
CHECK that the accessory
drive belt is running centrally
on the flat pulleys. TEST the
system for normal operation.
CHECK the pulleys for
excessive end float and bent
flanges.
With the engine running at idle,
use a stethoscope to identify
the source of the noise.
INSTALL new components as
necessary. TEST the system
for normal operation.

DIAGNOSIS AND TESTING

Installation).

TEST the system for normal operation.
2. Detach the accessory drive belt in the area of
the accessory drive belt tensioner.
3. N0TE:The accessory drive belt tensioner
has a damping feature, which is usually a
friction device, therefore some friction within
the system is normal.
Using the correct tool, move the accessory drive
belt tensioner from its relaxed position through
its full stroke and back to the relaxed position
to make sure there is no excessive stick, grab
or bind, and to make sure there is tension on
the accessory drive belt tensioner spring.
4. Rotate the accessory drive belt tensioner pulley
and check for damage, freedom of rotation and
alignment. INSTALL a new accessory drive belt
tensioner as necessary.
Accessory Drive Belt Tensioner - Dynamic
Check
The accessory drive belt tensioner may be checked
dynamically as follows:
1. With the engine running, observe the accessory
drive belt tensioner movement. The accessory
drive belt tensioner should move (respond)
when the engine is accelerated rapidly or when
the
A/C clutch cycles ON and OFF (the degree
of movement can be up to 4 mm). If the
accessory drive belt tensioner movement is not
constant without engine acceleration or
A/C
clutch cycling, a pulley or shaft is possibly bent,
out of round, or the damping mechanism inside
the accessory drive belt tensioner may be
damaged. INSTALL a new accessory drive belt
tensioner as necessary.
