When performing an oil change, remember to remove the dipstick to provide adequate venting and allow the oil to flow freely into the crankcase. After refilling, always check the oil level to ensure it is correct. The oil drain plug torque specification is 10 ft/lbs. Proper maintenance intervals are essential for this engine. Whether you choose the 25,000-mile Signature Series, the 20,000-mile Extended-Life, or the 12,000-mile High-Mileage oil, adhering to these intervals or one year, whichever comes first, will keep your truck running reliably.

Transmission and Drivetrain Protection

The 2001 Ford F350 often comes equipped with the 4R100 automatic transmission, which requires specific fluids to handle heavy loads and towing. For these transmissions, AMSOIL recommends using 100% synthetic Automatic Transmission Fluids that meet or exceed Ford specifications. The Signature Series Multi-Vehicle ATF is an ideal choice for drivers who tow heavy loads or drive in challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use. For those who prioritize fuel economy, the Signature Series Fuel-Efficient ATF helps improve efficiency while still offering top-tier protection against wear and thermal degradation.

For standard service needs, the OE Multi-Vehicle 100% Synthetic ATF and OE Fuel-Efficient ATF provide excellent cold-weather performance and resist harmful sludge. These fluids promote smooth, shudder-free shifts and guard against leaks. If your truck has a manual transmission, the same Multi-Vehicle ATF and OE ATF are recommended. It is crucial to note the specific fill capacities for the 4R100 transmission, which can range from a 4-speed 20-plate OAC requiring 17 quarts total fill to other variations requiring 17.6 quarts or an initial fill of 6.4 quarts. Always check your dipstick after refilling to ensure the correct level is maintained.

Protecting the drivetrain extends to the differentials and transfer case. For front differentials equipped with Dana 50 or Dana 60 housings, AMSOIL SEVERE GEAR 75W-90 100% Synthetic Gear Lube is a top recommendation. It contains friction modifiers for limited-slip applications and controls thermal runaway, helping to reduce operating temperatures and extending the life of seals and equipment. For rear differentials, such as the Dana 135 or Ford 10.5 RG, the 75W-90 or 75W-140 grades are suitable depending on your towing habits. Vehicles subject to frequent trailer towing in hot or hilly conditions should consider the heavier 75W-140 grade to protect against extreme wear. The 75W-90 Long Life Gear Lube is another option for extended service intervals, specifically engineered for 500,000-mile service life in over-the-road trucks.

Fluid capacities for differentials vary significantly. The Dana 50 front differential requires 3.8 pints, while the Dana 60 front requires 5.7 pints. For the rear Dana 135, the capacity is 24.5 pints, and for the Dana 80 rear, it is 8.5 pints. The Ford 10.5 RG rear differential holds 7 pints. For transfer cases, the capacity is approximately 4 pints. Selecting the correct gear lube ensures that gears mesh smoothly, reducing noise and wear on bearings and gears.

Cooling and Brake Systems

Proper cooling is vital for the longevity of the 5.4L engine, especially under load. The cooling system for the 2001 Ford F350 has a capacity of 26.4 quarts.
