Adjustment

Specific to:

Ford Escape 2008-2009

Mercury Mariner 2008-2009

The belts used on these vehicle are equipped with automatic (spring load) tensioners which maintain tension. No adjustment is necessary or possible.

Belt Routings

Ford Escape 2006-2008

Mercury Mariner 2006-2008

Inspection

Specific to:

Ford Escape 2008-2009

Mercury Mariner 2008-2009

WARNING

Under no circumstances should the accessory drive belt, tensioner or pulleys be lubricated as potential damage to the belt material and tensioner damping mechanism will occur. Do not apply any fluids or belt dressing to the accessory drive belt or pulleys.

The water pump drive belt is on back of engine. It is driven off the rear cam pulley and doesn-t have any adjustments.

V- Ribbed Serpentine Belt With Piling

Specific to:

Ford Escape 2008-2009

Mercury Mariner 2008-2009

NOTE

Piling is an excessive buildup in the V-grooves of the belt.

The condition of the V-ribbed drive belt should be compared against the illustration and appropriate action taken.

1. Small scattered deposits of rubber material. This is not a concern, therefore, installation of a new belt is not required.
2. Longer deposit areas building up to 50 percent of the rib height. This is not considered a concern but it can result in excessive noise. If noise is apparent, install a new belt.
3. Heavy deposits building up along the grooves resulting in a possible noise and belt stability concern. If heavy deposits are apparent, install a new belt.

V-Ribbed Serpentine Belt With Chunks Of Rib Missing

Specific to:

Ford Escape 2008-2009

Mercury Mariner 2008-2009

There should be no chunks missing from the belt ribs. If the belt shows any evidence of this, install a new accessory drive belt.

Fig. Replace the belt if missing chunks are found during inspection

V-Ribbed Serpentine Drive Belt With Cracks Across Ribs

Specific to:

Ford Escape 2008-2009

Mercury Mariner 2008-2009

NOTE

Up to 15 cracks in a rib over a distance of 4 inches (100mm) can be considered acceptable. If damage exceeds the acceptable limit or any chunks are found to be missing from the ribs, a new belt must be installed.

1. Check the belt for cracks. Up to 15 cracks in a rib over a distance of 4 inches (100mm) can be considered acceptable. If cracks exceed this standard, install a new belt.

Visual Inspection

Specific to:

Ford Escape 2008-2009

Mercury Mariner 2008-2009

Visually inspect the belt for obvious signs of mechanical damage:

Drive belt cracking/chunking/wear

Belt/pulley contamination

Incorrectly routed belt

Pulley misalignment or excessive pulley runout

Loose or mislocated hardware

Incorrectly routed power steering tubes (rubbing)

Eliminate all other non-belt related noises that could cause belt misdiagnosis, such as A/C compressor engagement chirp, power steering cavitations at low temperatures, variable camshaft timing (VCT) tick or alternator whine.

If a concern is found, correct the condition before proceeding to the next section.

V- Ribbed Serpentine Belt With Piling

Specific to:

Ford Escape 2006-2008

Mercury Mariner 2006-2008

NOTE
