How To Replace Accessory Drive Belts on Ford Expedition and Lincoln Navigator?

The procedure is similar for both ford and Lincoln car models:-----

Accessory Drive Belts Inside section details are as follows:---

ADJUSTMENT

BELT ROUTINGS

INSPECTION

REMOVAL & INSTALLATION

Adjustment

Specific to:

Ford Expedition 2008-2009

Lincoln Navigator 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

Specific to:

Ford Expedition 2008-2009

Lincoln Navigator 2008-2009

Inspection

Specific to:

Ford Expedition 2008-2009

Lincoln Navigator 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.

V- Ribbed Serpentine Belt With Piling

Specific to:

Ford Expedition 2008-2009

Lincoln Navigator 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 Expedition 2008-2009

Lincoln Navigator 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

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

V-Ribbed Serpentine Drive Belt With Cracks Across Ribs

Specific to:

Ford Expedition 2008-2009

Lincoln Navigator 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 Expedition 2008-2009

Lincoln Navigator 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 generator whine.

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

Removal & Installation

Specific to:

Ford Expedition 2008-2009

Lincoln Navigator 2008-2009

1. Remove the air cleaner outlet pipe.
2. Rotate the drive belt tensioner clockwise and remove the drive belt.
   
   
   

   

   Fig. Rotate the drive belt tensioner clockwise and remove the drive belt

To install:

1. Installation is the reverse of the removal procedure. Make sure the belt is routed properly.

The details are as follows :----

Accessory Belt Routing

Adjustment

Power Steering Pump Belt
2001-02 Models

1. Loosen the power steering pump mounting nut (A) and bolt (B).
2. Turn the adjusting nut (C) to get the proper belt tension, then retighten the mounting nut and bolt.
3. Start the engine and turn the steering wheel from lock-to-lock several times, then stop the engine and recheck the tension of the belt.

Except 2001-02 Models

Belt tension is automatically maintained by a belt tensioner. No adjustments are necessary.

Inspection

Power Steering Pump Belt
2001-02 Models

NOTE

There are two ways to inspect the belt tension: the Belt Tension Gauge Method and the Deflection Method. Both are outlined below.

Belt Tension Gauge Method

1. Attach the belt tension gauge to the belt with the gauge face toward the engine, and measure the tension of the belt. Follow the manufacture's instructions. If the belt is worn or damaged, replace it.
   
   NOTE

   Remove the belt tension gauge carefully to avoid hitting the gauge reset lever.
2. The tension should be:
   1. Used Belt: 88-120 lbs. (390-540 N)
   2. New Belt: 165-198 lbs. (740-880 N)
3. If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specifications.
   
   
   

   

   Fig. Using a belt tension gauge to inspect the power steering pump belt tension

Deflection Method

1. Apply a force of 22 lbs. (98 N) and measure the deflection between the power steering pump pulley (A) and the crankshaft pulley (B).
2. The deflection should be:
   1. Used Belt: 0.51-0.65 in. (13.0-16.5mm)
   2. New Belt: 0.33-0.43 in. (8.5-11.0mm)
3. If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specifications
   
   
   

   

   Fig. Apply a force of 22 lbs. then measure the deflection between the power steering pump pulley (A) and the crankshaft pulley (B)

Except 2001-02 Models

1. Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.
2. On 2001-02 models, check that the pointer (A) on the auto-tensioner housing is not beyond the edge of the indicator rib (B) on the tensioner base.

Removal & Installation

2001-02 Models
Alternator-A/C Compressor Belt

1. Note the radio security code and disconnect the negative battery cable.
2. Move the auto-tensioner (A) to relieve tension from the alternator belt (B), and remove the alternator belt.
3. Install the new belt in the reverse order of removal.
   
   
   

   

   Fig. Move the auto-tensioner (A) to relieve tension from the alternator belt (B), and remove the alternator belt

Power Steering Pump Belt

The power steering pump has two fasteners securing it to a bracket mounted on the engine. The right side locknut and fastener are installed through a slotted bracket and the left side fastener allows the pump to pivot.

1. Note the radio security code and disconnect the negative battery cable.
2. Loosen the right side locknut and left side pivot nut.
3. Move the pump by turning the adjustment nut on the right side bracket. Turn the adjustment nut counterclockwise to release the belt tension.
4. Remove the belt from the pulleys, one pulley at a time.

To install:

1. Install the belt around the pulleys, beginning with the largest pulley first.
2. Follow the adjustment procedure to correctly tension the belt.
3. Tighten the right side locknut and left side pivot bolt and then check the belt tension. If the belt tension is not within specification, repeat the adjustment procedure until the proper belt tension is achieved.
4. Reconnect the negative battery cable and enter the radio security code.

2005-06 Models

NOTE

For this procedure, you will need a Belt tension release tool (Snap-on YA9317) or equivalent.

1. Move the auto-tensioner (A) with the belt tension release tool to relieve tension from the drive belt (B), then remove the drive belt.
2. Install the new belt in the reverse order of removal.
