🔧 Maintenance

Oil Change:

Every 3,000-5,000 miles or 3-6 months (dependent on driving conditions and oil type used). Refer to manual for precise recommendation.

Engine Coolant:

Initial flush at 50,000 miles, then every 30,000 miles or 2 years. Consult manual for specific interval.

Transmission Fluid:

Every 30,000-50,000 miles or as per manual recommendation. Crucial for AXOD-E transmission longevity.

SAE 5W-30 or 5W-40, API SJ or higher. Check manual for specific viscosity recommendation based on ambient temperature.

Brake Fluid:

DOT 3

Power Steering Fluid:

Type-F or MERCON® Automatic Transmission Fluid (check manual for specific application).

Transmission Slippage:

AXOD-E transmissions can be prone to wear and slippage if not properly maintained. Torque converter clutch solenoid failures are not uncommon.

Engine Idle Roughness:

Can be caused by vacuum leaks, dirty fuel injectors, or faulty idle air control (IAC) valve, especially on the Vulcan V6.

Electrical Gremlins:

Older Fords of this era can experience issues with wiring harnesses, grounds, and control modules, leading to intermittent electrical problems.

Exhaust Manifold Cracks:

The 3.8L Essex V6 is known to be susceptible to exhaust manifold cracks, leading to exhaust leaks and ticking noises.

Oil Filter Example:

Motorcraft EFL-134 or equivalent (e.g., Fram PH8A, Wix 51515). Consult manual for confirmed application.

Air Filter Example:

Motorcraft FA-78 or equivalent. Consult manual for confirmed application.
