The 3.5L EcoBoost typically uses a cartridge-style oil filter rather than a traditional spin-on canister. The exact part numbers vary by model year and vehicle, but the cartridge design is standard across Ford’s 3.5L EcoBoost lineup.
Understanding this design matters because it affects how you service the engine. Instead of a full canister that you unscrew, you replace only the filter element inside a housing and reseal the cap with a new O-ring. This guide explains what to expect and how to perform a typical replacement.
Filter Type and How It Works
Most 3.5 EcoBoost engines use a replaceable cartridge filter housed in a sealed plastic or metal housing. The filter element sits inside the housing, and the cap is removed to access and replace the cartridge. The design is intended to simplify maintenance and allow for a straightforward replacement of the filtering material, rather than a full canister swap.
- Cartridge-style oil filter inside a housing, replaced by swapping the cartridge element.
- Not a traditional spin-on canister; you remove the housing cap to access the cartridge.
- OEM and aftermarket cartridge kits are available; common choices include Motorcraft and other reputable brands compatible with the 3.5 EcoBoost design.
- Access location varies by model year, but the filter housing is typically under the hood and requires a cap wrench or socket to remove the cap and replace the element.
In short, the 3.5 EcoBoost relies on a cartridge-style filter inside a housing, not a standard spin-on canister. When servicing, use the correct cartridge kit and replace the housing cap O-ring to ensure a proper seal.
Replacement Steps and Tips
When you’re ready to service, follow these general steps. Always consult your owner's manual or a service manual for model-specific torque specs and procedures.
- Warm up the engine briefly, then park safely and engage the parking brake. Gather a pan to catch old oil.
- Drain the engine oil by removing the drain plug and letting it flow into the pan. Reinstall the drain plug once draining is complete.
- Locate the oil filter housing cap. Use the appropriate tool or socket to loosen and remove the cap, being prepared for residual oil to spill.
- Remove the old cartridge from the housing and discard it. Take care not to spill residual oil.
- Install the new cartridge into the housing. Replace the housing cap O-ring with a fresh one, and reinstall the cap to the specified torque.
- Replenish with fresh oil to the vehicle’s recommended capacity (typically around 6 quarts with filter, but verify your manual). Start the engine, check for leaks, and scan the oil level with the dipstick, topping off as needed.
Concluding note: dispose of used oil responsibly at an approved facility, and record the service in your maintenance log. If you’re unsure about the procedure, have a qualified technician perform the replacement to ensure proper sealing and oil flow.
Parts and Where to Buy
Parts for the 3.5 EcoBoost cartridge-filter design are widely available from Ford Motorcraft and various aftermarket brands. When shopping, ensure you’re selecting a cartridge-type filter designed for the 3.5 EcoBoost engine and the correct year/model.
- OEM cartridge oil filters from Ford/Motorcraft designed for the 3.5 EcoBoost.
- Aftermarket cartridge filters from brands such as Wix, Bosch, Mann-Filter, Mahle, and similar that specify compatibility with the 3.5 EcoBoost cartridge design.
- Oil filter housing cap O-ring kits and any recommended cap tools if needed for your vehicle.
Note: Always verify compatibility with your specific vehicle year and trim level, as there can be slight variations in the filter housing and cap design across different generations of the 3.5 EcoBoost.
Summary
The Ford 3.5L EcoBoost generally uses a cartridge-style oil filter housed in a removable cap, rather than a spin-on canister. Replacement involves swapping the filter cartridge, replacing the housing cap O-ring, and refilling with the recommended oil. Parts are readily available from OEM and reputable aftermarket brands, but always confirm year/model compatibility and follow the vehicle’s service guidance for proper installation and oil capacity. Regular maintenance and proper disposal of used oil help keep the engine running smoothly.
