Known Problems

The Ford Explorer Sport Trac with the 100% plastic intake manifold  is known for engine overheating, even with normal use, and a coolant leak from the front of the manifold. This will often trigger the check engine light and low engine coolant warning light.

The engine coolant leak is from a factory defect, which causes cracking on the front coolant passage of the intake manifold. In a very short time, this leak will lead to engine overheating issues, especially while the vehicle is idling.   

Between 1999 and 2001, Ford released an updated version of this engine, known as the 'PI' version with a metal coolant passage on the front of the intake manifold, to prevent future issues.

There is no factory authorized repair for the intake manifold, and replacement is required to correct the engine coolant leak and overheating issues.

 

A coolant leak may develop from the radiator. Ford has released and updated radiator and powertrain control module (PCM) software update to address this issue. The software update includes revised cooling fan operating parameters. Failure to complete both service procedures may result in repeated radiator failures.

Replace the worn wheel bearings.

A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should correct this concern.

The Ford Explorer Sport Trac is known for a rough idle, engine stalling, loss of power, and misfires, accompanied by the check engine light.

The intake manifold O-ring gaskets commonly leak, which creates a large vacuum leak. This vacuum leak causes unmetered air to enter the engine, and the fuel system becomes insufficient to compensate for the large amount of air reaching the engine. 

Replacing the intake manifold gaskets corrects this concern.

Various problems with the 5-speed automatic transmission were common. These problems can be more common on the 2002 models with build dates before March, 2002. There are many service bulletins describing the diagnoses and repairs, which include fluid leak repairs, transmission software updates, or internal failures requiring a costly repair.

The rear wiper may stop working. This could be due to a rear wiper motor that has failed requiring replacement.
