2003 Mercury Mountaineer Problems

Worn Timing Chain Cassettes May Cause Rattling Noise From Engine

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.

Vacuum leak from intake manifold O-ring gaskets

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

Plastic Intake Manifold May Crack Causing Coolant Leak

The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.
