Parts for your 2016 Ford Territory-Sump plug washers

2016 Ford Territory sump plug washers — what they do and when to replace

Yes, the 2016 Ford Territory (SZ II, both the 4.0L petrol I6 and 2.7 TDCi diesel) uses a sump plug sealing washer. Ford’s workshop literature for the SZ/SZ II platform specifies fitting a new drain plug washer or a plug with an integral gasket at each oil change, and major aftermarket catalogues list a sump plug washer for this model range. That means this little seal is very much part of routine servicing, not an optional extra.

The sump plug washer’s job is simple and critical: it seals the drain plug to the alloy or steel sump so engine oil can’t seep out after a service. Depending on engine/plug type, the Territory uses either a crush-style metal washer (typically copper or aluminium) or a drain plug with a bonded rubber/nylon gasket. The crush type deforms once to take up any tiny imperfections between the plug and sump face, while the bonded type provides an elastic seal. Either way, a fresh, correctly sized washer helps keep the sump bone dry and the driveway clean.

Best practice is to replace the washer every time the plug is removed. That aligns with Ford service procedures and avoids weeps that show up a week after an oil change. If the vehicle has the bonded-gasket style plug, inspect the gasket closely, if it’s nicked, flattened or hardened, replace the plug or gasket as applicable. Always clean the sump sealing face, start the plug by hand to avoid cross-threading, and tighten to the factory torque (around 30 Nm, check the workshop manual for the exact spec per engine).

• Tell-tales of a crook washer: dampness around the plug, oil mist on the undertray, or a drip after parking.
• Handy servicing tip: keep a few correct washers on the shelf, they’re cheap insurance against comebacks.

Sizing can vary by engine and plug design, but most Territory applications use an M14 drain plug with a matching washer. Don’t guess—confirm by VIN/rego lookup or the engine code, and match the inner diameter and style (crush vs bonded) to the plug you’re fitting.

Fresh oil is only as good as the seal that keeps it in. Swapping the sump plug washer at each service is a quick, low-cost step that protects the engine, saves mess, and keeps the Territory ready for the next school run or road trip.

FAQs

Does a 2016 Ford Territory need a new sump plug washer every service?
It’s strongly recommended. Ford’s service information calls for a new sealing washer (or a plug with an integral new gasket) whenever the oil is drained. That prevents weeps and keeps the sump properly sealed. If the plug uses a bonded gasket, inspect it carefully and replace if there’s any damage or flattening.

What size sump plug washer fits a 2016 Territory?
Most use an M14 drain plug with a matching washer, but there are variations between petrol and diesel and by plug style. Use a parts lookup by VIN or engine code to confirm inner diameter and type (copper/aluminium crush or bonded gasket) before fitting.

What torque should the sump plug be tightened to?
Expect roughly 30 Nm, but always check the exact spec in the Ford workshop manual for the specific engine. Over-tightening can crush the washer too far or damage sump threads, under-tightening risks a slow leak.
