Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanicaldamage.
Visual Inspection Chart
Mechanical
– Damaged or contaminated accessory drive belt or air conditioning (A/C) compressor belt
– Damaged or contaminated pulley(s)
– Incorrect accessory drive belt or A/C compressor belt
– Incorrect fitment of the accessory drive belt or A/C compressor belt
– Accessory drive belt tensioner
– Accessory drive belt idler pulley
– Generator
– A/C compressor
– A/C compressor belt tensioner
– Pulley(s)
– Loose hardware
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible)
before proceeding to the next step.
Accessory Drive Belt Concerns
CAUTION: Do not lubricate the accessory
drive belt, accessory drive belt tensioner(s)
or idler pulley(s) as potential damage to
the accessory drive belt material
construction, accessory drive belt
tensioner damping mechanism, accessory
drive belt tensioner pulley bearing and idler
pulley(s) bearing may occur.
NOTE: All the diagnosis and testing information
contained within this procedure can be used for
the accessory drive belt and the A/C compressor
belt.
Cracking
Accessory drive belts are made from rubber which
hardens with time and can develop cracks. As the
accessory drive belt runs on the back of some of
the pulleys, the cracks are opened up. Small cracks
are not considered to be a failure of the accessory drive belt. Only if the crack is deep enough to reach
the bottom of the groove to expose the cord or any
chunks are found to be missing from the accessory
drive belt, is the accessory drive belt condition
considered to be unacceptable.
1. Check the accessory drive belt for cracks. If the
damage exceeds the acceptable limit, install a
new accessory drive belt.

Chunking
Chunking describes the condition where long
lengths of rubber become detached from the ribs
of the accessory drive belt. This is considered to
be a failure of the accessory drive belt.

2. Check the accessory drive belt for damage. If any chunks are found to be missing, install a
new accessory drive belt.

FORD KUGA 2011.0MY WORKSHOP REPAIR MANUAL

Pilling
Pilling is dust that forms in between the ribs of the
accessory drive belt from rubber that is worn off
the accessory drive belt when it is new. There may
also be loose particles left on the accessory drive
belt during the manufacturing process. These are
worn off and form into small balls of rubber that
then get trapped in the grooves of the accessory
drive belt. This condition will usually clear itself
within 4800 km - 8000 km (3000 miles - 5000 miles)
of normal driving.
VUE0037805
3. Check the accessory drive belt for pilling. Thecondition of the accessory drive belt should be
compared against the illustration.
1. Small scattered pills. Not considered a concern. No action required.
2. Small scattered pills. Not considered a concern. No action required.
3. Longer pills up to 50% of the rib height. Possible noise concern. INSTALL a new
accessory drive belt if noise is apparent.

the accessory drive belt being incorrectly fitted on
the pulley as shown in the following illustration.
Make sure that all the V grooves on the accessory
drive belt contact correctly with the pulley.

Symptom Chart
Action
Possible Sources
Symptom
• CHECK the system with theengine running and the
accessory drive belt removed
(only run the engine for a very
short period). If a noise is
apparent, the cause is not the
accessory drive system. If a
noise is not apparent, the
cause is the accessory drive
system. CHECK where the
noise is coming from. Use a
stethoscope or other listening
device to determine the source
of the noise. INSTALL new
components as necessary.
TEST the system for normal
operation.

Component Tests
Accessory Drive Belt Tensioner - Static
Check
The accessory drive belt tensioner may be checked
statically as follows:
1. Inspect the area surrounding the accessorydrive belt tensioner for lubricant or other
contamination. Rectify any leaks before
installing a new accessory drive belt tensioner.
If the accessory drive belt tensioner is
contaminated, do not attempt to clean it as the
damping mechanism inside may be damaged.
INSTALL a new accessory drive belt tensioner
as necessary.

2. Detach the accessory drive belt in the area of the accessory drive belt tensioner.
3. NOTE: 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

5. If the accessory drive belt tensioner meets the above criteria, proceed to test the accessory
drive belt tensioner dynamically. If the accessory
drive belt tensioner does not meet the above
criteria, INSTALL a new accessory drive belt
tensioner.

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.

2. Excessive accessory drive belt rideout (uneven depth of grooves in the accessory drive belt)
may cause excessive accessory drive belt
tensioner movement. Check the condition by
installing a new accessory drive belt.
