Parts for your 2022 Ford Fiesta-Sump plug washers

2022 Ford Fiesta sump plug washers — what’s actually fitted

For the 2022 Ford Fiesta, a traditional separate sump plug washer isn’t generally used. Ford’s workshop guidance for the Mk8 Fiesta range (including the 1.0 EcoBoost and 1.5 EcoBoost ST in 2022) specifies an oil drain plug that seals with an integrated bonded washer or an O-ring on the plug itself, replaced as an assembly. This is reflected in Ford service manuals, Ford/Motorcraft parts catalogues (Microcat/ETIS), and independent service data such as Autodata and Haynes Online, which note “renew drain plug and seal” rather than a separate copper crush washer.

Why no separate washer? Ford moved many late-model Fiesta engines to drain plugs with captive seals to reduce leak risk and make servicing more foolproof. With a plastic or coated alloy sump, the controlled, built-in seal helps protect the sump face and gives more consistent sealing than mixing and matching aftermarket washers.

• The plug’s seal is engineered to crush or compress once, so it’s a single-use item designed to be renewed at oil changes.
• There’s no listing for a stand-alone sump plug washer on most 2022 Fiesta engine codes, the listed part is the plug with the seal attached.
• Using an add-on copper or fibre washer under these plugs can prevent the seal from sitting correctly and may cause leaks.

Servicing tips for a 2022 Fiesta: order the correct Ford-spec drain plug that includes its captive seal or O-ring. Clean the sump’s sealing face, fit the new plug by hand first to avoid cross-threading, then tighten to the manufacturer’s torque specification from service data. Don’t stack a separate washer under the head, and don’t re-use a distorted or flattened integrated seal. If the old plug must be refitted in a pinch, check carefully for weeping after the first heat cycle and plan to replace it promptly.

Technical references consulted: Ford workshop/service information for Fiesta Mk8 (2017–2023), Ford/Motorcraft parts catalogues showing drain plug with captive seal for applicable 2022 engines, and Autodata/Haynes Online service schedules indicating renewal of the plug/seal assembly rather than a separate washer.

Popular questions

Does a 2022 Ford Fiesta need a separate sump plug washer?
Not typically. Most 2022 Fiesta engines use a one-piece drain plug with a built-in seal. Replace the entire plug each service, as Ford specifies, rather than adding a separate copper or fibre washer.

What should be replaced during an oil change if there’s no washer?
Fit a new, correct-spec Ford/Motorcraft (or equivalent) drain plug that includes its captive seal or O-ring, along with the oil filter and specified oil. This keeps the sealing system as designed and helps prevent drips.

Can the integrated-seal drain plug be reused?
Ford service information treats the plug/seal as single-use. While some people reuse them, it increases the chance of seepage. If reuse is unavoidable, inspect for damage and monitor for leaks, then replace with a new plug at the next opportunity.
