Parts for your 2019 Ford Everest-Sump plug washers

2019 Ford Everest sump plug washers — what they do and when to change them

For the 2019 Ford Everest, a sump plug sealing washer is indeed used. Ford’s Workshop Manual for the PX-series Ranger/Everest platform (2019 models) specifies fitting a new sealing washer when refitting the engine oil drain plug during an oil change, and the Ford electronic parts catalogue lists a dedicated sealing washer for the drain plug on both the 3.2L Duratorq and 2.0L Bi‑Turbo diesel variants. These technical sources confirm the part is relevant to this vehicle.

On this Everest, the sump plug washer’s job is simple but critical: it seals the drain plug against the sump so engine oil can’t weep out after a service. The washer is typically a soft metal crush type (usually aluminium or copper) that deforms once to create a tight seal, or on some variants the plug may have a bonded rubber O‑ring that achieves the same effect. Either way, it’s a single‑use sealing surface by design.

Because that washer crushes once and takes a “set”, the best practice is to replace it at every oil change. Reusing a flattened washer can lead to small leaks, oil misting on the underside, or the temptation to over‑tighten the plug to chase a seal—risking damaged threads in the sump. Ford’s service procedure also calls for tightening the drain plug to the specified torque with a new washer in place, owners should follow the exact spec in the Workshop Manual for their engine code rather than guessing.

For Aussie and Kiwi owners who tour, tow or go off‑road, keeping a couple of spare washers in the glovebox is a smart move. They’re inexpensive, take no room, and can save a headache on a roadside oil change. When servicing the Everest:

• Confirm the correct washer type for the specific engine (crush washer vs. integral O‑ring plug).
• Clean the sump sealing face and the plug head before refitting.
• Fit a fresh washer (or a new plug if it uses an integral O‑ring) and tighten to the Ford spec with a torque wrench.
• Never use thread tape or sealant—if a new washer won’t seal at the correct torque, replace the washer/plug and inspect the mating face.

Signs it’s time for a new washer outside the normal 12‑month/15,000 km service rhythm include a fresh drip on the driveway, oil mist around the plug, or a washer that looks grooved, split or over‑flattened when removed. Simple part, big peace of mind.

Popular questions about 2019 Ford Everest sump plug washers

Does the 2019 Everest actually have a sump plug washer?
Yes. Ford’s Workshop Manual procedure for draining/refilling engine oil specifies installing a new sealing washer on refit, and the Ford parts catalogue lists a separate washer for the drain plug. Some engines use a crush washer, others use a plug with an integral O‑ring—both are service items.

How often should the washer be replaced?
Replace it at every oil change (typically 12 months/15,000 km in AU/NZ, or sooner in severe conditions). If the plug on a particular engine has an integral O‑ring, replace the whole plug each service as per the manual.

What size/type washer does it use?
Most 2019 Everest diesels use a 14 mm drain plug with a soft‑metal crush washer, but owners should match by VIN or check the Ford Workshop Manual/parts catalogue for their exact engine and build. Using the correct washer type and torquing to the Ford spec is essential for a reliable seal.
