Parts for your 2022 Ford Ranger-Sump plug washers

2022 Ford Ranger sump plug washers — are they used and what to know

Yes, a sump plug washer is used on the 2022 Ford Ranger. Ford’s own technical literature backs this up: the Ford Workshop Manual for the 2022 Ranger (PX MkIII) in the Engine Lubrication section instructs replacing the drain plug sealing washer during an oil change and tightening the plug to the specified torque. Ford’s parts catalogues (e.g., Microcat/ECAT) also list a dedicated sealing washer for the oil drain plug by VIN for 2019–2022 PX MkIII Rangers, and the Owner’s Manual section on Capacities and Specifications provides the oil drain plug torque, consistent with a crush/bonded washer design. Depending on engine and build date, some Rangers use a separate copper/aluminium crush washer, while others use a drain plug with a captive bonded washer that’s replaced as an assembly.

That tiny washer does a big job. It forms a reliable seal between the drain plug and the sump, compensating for machining tolerances and minor surface imperfections so oil doesn’t weep out after a service. On crush types, the soft metal deforms once to create the seal, on bonded styles, a rubber-like gasket does the sealing against the pan and plug flange.

As part of regular servicing, the washer should be treated as a consumable. On a crush washer, it’s single-use — once it’s compressed, it won’t seal as well next time. On plugs with an integrated bonded washer, the whole plug is treated as one-time-use. Using the right style for the engine variant (2.0L Bi-Turbo, 3.2L, etc.) is important, mixing types can lead to drips or stripped threads.

• Replace the washer (or one-time-use plug) at every oil change.
• Clean the sump face and plug flange, remove old washer fragments.
• Torque the plug to spec — typically around 30 N·m for many PX MkIII Rangers, but always follow the exact figure in the Ford Workshop Manual for the specific engine.
• Don’t use thread sealant, the washer does the sealing.
• If the plug head or threads look chewed, replace the plug along with the washer.

Genuine or OE-quality copper/aluminium washers and bonded-seal plugs are inexpensive insurance against leaks and come recommended by Ford’s service documentation. It keeps the Ranger tidy underneath and saves owners from annoying oil spots on the driveway.

Popular questions

What size sump plug washer does a 2022 Ford Ranger use?
Most 2022 PX MkIII Rangers use an M14 sealing interface. Depending on engine and build, that’s either an M14 copper/aluminium crush washer or an M14 plug with a captive bonded washer. The safest bet is to confirm by VIN or engine code so the correct washer or one-time-use plug is on hand before the service.

Should the washer be replaced at every service?
Yes. Ford’s service information treats the drain plug washer (and captive-washer plugs) as replace-once items. Reusing a crushed or bonded seal increases the chance of weeping or needing extra torque, which can damage threads in the sump.

What torque should the drain plug be tightened to?
The exact torque depends on engine and plug design. Many PX MkIII Rangers specify roughly 30 N·m for the M14 plug. Always follow the torque in the Ford Workshop Manual or the Owner’s Manual for the engine fitted to the vehicle.
