Parts for your 2010 Ford Transit-Sump plug washers

2010 Ford Transit sump‑plug‑washers: what they do and when to replace them

Technical sources confirm the 2010 Ford Transit uses a sump‑plug washer on the engine oil drain plug. The Ford Workshop Manual for Transit (2006–2013, WSM) and the Haynes Transit Diesel service manual both specify a replaceable sealing washer for the drain plug and advise fitting a new one during oil changes. That makes sump‑plug‑washers relevant kit on this model.

On a 2010 Ford Transit, the sump‑plug‑washer is a simple, single‑use seal that sits under the head of the drain plug. When the plug is tightened, the washer compresses slightly to create a reliable, leak‑free seal against the sump. Most Transits of this era use either a soft copper or aluminium crush washer, some variants or aftermarket plugs use a bonded (metal‑and‑rubber) type. Engine families in this model year can differ, so washers commonly come in M14 or M18 sizes depending on engine and drivetrain—always match to the plug on the vehicle.

Because crush washers deform to seal, they’re designed to be replaced at every oil service. Re‑using an old washer can lead to weeping around the plug, oil drops on the driveway, and a mess under the van. The cost of a fresh washer is tiny compared with the risk of leaks or a stripped plug from overtightening. Ford service information calls for a new washer at refit, and that’s the smart move for owners and workshops alike.

When servicing a 2010 Transit, clean the sump face and plug, fit the correct new washer, and tighten the plug to the specified torque. Typical drain plug torque for these Transits sits in the ~28–35 Nm range, varying by engine, so it’s best to check the exact spec for the VIN and engine code. Avoid thread sealants or tape—they’re not needed when the right washer and torque are used.

Good practice under the bonnet includes replacing the sump‑plug‑washer at each oil change interval (often 15,000 km or 12 months in AU/NZ conditions), inspecting the plug threads and magnet, and watching for any post‑service drips. Owners can keep a small pack of the correct washers on hand, making each service quick, tidy and drama‑free.

• Use a new, correct‑size washer every oil change
• Clean mating surfaces and torque the plug correctly
• If unsure on size (M14 vs M18), confirm by VIN or measuring the plug

Popular questions about 2010 Ford Transit sump‑plug‑washers

What size sump‑plug‑washer does a 2010 Ford Transit use?
It depends on the engine and drivetrain. Many 2.2 TDCi FWD models use an M14 drain plug with a matching crush washer, while some 2.4 TDCi RWD variants use an M18 plug and washer. The safest approach is to check the plug on the vehicle, measure the thread, or confirm by VIN/engine code against parts data.

Do the washers need to be replaced every oil change?
Yes. The factory guidance and common workshop practice are to replace the crush washer at each oil service. They’re designed to deform once to make a proper seal. Re‑using can cause seepage or require over‑tightening, which risks damaging the plug or sump threads.

What torque should the sump plug be tightened to?
For 2010 Transit diesel engines, the drain plug torque typically falls around 28–35 Nm, varying by engine family. Using a torque wrench with a fresh washer gives the best seal. If the exact spec isn’t to hand, consult the engine‑specific workshop information for the vehicle’s VIN.
