An alternator pulley, of the incorrect size, installed at the factory can be the cause of drive belt failure and illumination of the battery light. The alternator pulley should be inspected and replaced as necessary if the drive belt brakes. When the new belt installed, it must be adjusted to the proper tension.

A defective electronic throttle body (ETB) can cause the Check Engine Light to illuminate and could have limited to no throttle response. Our technicians tall us that replacing the electronic throttle body will commonly correct this concern.

One or more oxygen sensors may fail resulting in illumination of the Check Engine Light.

The Check Engine Light can illuminate with codes due to the lack of EGR (exhaust gas recirculation) flow caused by the intake manifold passage plugging up with carbon and oil. The EGR valve has to be removed and the passage cleaned thoroughly. Partial restriction of this passage can cause Smog test failures for the NOx emissions without causing a drivability symptom.

The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.

The intake manifold O-ring gaskets commonly leak, causing stalling and poor idle quality; the Check Engine Light will illuminate.

A spring in the seat belt buckle may wear or fail, causing the airbag light on the instrument panel to illuminate. Failed buckles will require replacement.

4wd vehicles may develop a squealing noise coming from the front wheels when driving below 30 mph. This is generally caused by dry excluder seals, lubricating the seals will commonly correct this concern.

The EGR valve position (EVP) sensor can fail on this vehicle. The EVP sensor measures the EGR valve position and transmits the date to the engine control computer. If it fails, drivability and fuel economy can suffer, the Check Engine Light will commonly illuminate.

It is not uncommon for the intake manifold and/or valve cover gaskets to develop a coolant or oil leak. Leakage from the intake manifold may result in coolant in the engine oil. Coolant mixing with the engine oil severally impacts the lubrication ability of the oil. Internal engine may result if this condition is not repaired promptly.

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

A coolant leak may develop from a plug on the front of the rear cylinder head, behind the timing cover.

The steering gear may have an internal problem that makes turning to one side difficult; it may need to be replaced. A wheel alignment is needed after the steering gear is replaced.

Squeaks and creaks heard while driving over bumps and turning can be caused be a couple common sources and should be carefully diagnosed. Possible weld issues on the lower control arms can cause the noise concerns and require repair kits for the lower control arms from Ford. A jounce bumper (bump stop) rubbing against dry strut plate can cause an abrasion noise from the strut area. In this case the strut assembly should be disassembled to lubricate the jounce bumper and then reinstalled.
