Parts for your 2013 Ford Ranger-Sump plug washers

2013 Ford Ranger sump plug washers — what they do and when to replace them

Based on the Ford Workshop Manual for the PX Ranger (2011–2015, 2.2L and 3.2L Duratorq) and the Ford parts catalogue listings for the oil drain plug assembly, the 2013 Ford Ranger uses a sump plug sealing washer. The workshop procedure calls for discarding the old washer and fitting a new one during an engine oil change. The Ford electronic parts catalogue (Microcat/GSPC) also lists the drain plug and the M14 crush-type sealing washer as separate service items. Mazda’s BT-50 (shared platform) workshop documentation mirrors this requirement for a new drain plug gasket at each service. So yes — a sump plug washer is fitted and relevant to servicing a 2013 Ford Ranger.

On the 2013 Ranger, the sump plug washer is there to do a simple but vital job: seal the drain plug to the alloy steel sump so engine oil can’t weep out under heat, vibration, and pressure changes. Most are a soft crush washer (usually copper or aluminium) or a plug with a bonded rubber face. When tightened to the correct torque, the washer deforms slightly to take up tiny imperfections between the plug and sump face, giving a reliable, leak-free seal.

As part of routine servicing, it’s good practice to replace the washer at every oil change. They’re inexpensive, and a fresh one helps avoid slow drips that leave spots on the driveway and, worse, a gradual oil loss over thousands of kilometres. If someone’s in a bind, they can visually inspect the old washer for grooves, hardening, or distortion — any of those are a cue to bin it and install a new one. A bonded-washer plug should be swapped if the rubber is flattened, cracked, or loose on the carrier.

Handy tips for the Ranger’s sump plug washer:

• Use the correct size: typically M14 for PX-series Rangers, match the original style (crush or bonded).
• Tighten to the specified torque for the engine variant (around 30 Nm is common — check the spec under the bonnet decal or workshop data).
• Clean the sump face before refitting so the new washer seats properly.
• After the first short drive, have a quick look under the ute for any fresh oil trace around the plug.

Do that, and the 2013 Ranger’s lubrication system stays tidy, with the sump sealed up sweet as, service after service.

Popular questions about 2013 Ford Ranger sump plug washers

Does a 2013 Ford Ranger actually have a sump plug washer?
Yes. Ford’s PX Ranger workshop procedures specify replacing the sealing washer during oil changes, and the Ford parts catalogue lists the washer separately to the drain plug. It’s a standard fitment on both 2.2L and 3.2L Duratorq diesels.

How often should the washer be replaced on a 2013 Ranger?
Best practice is every oil change. Crush washers harden and take a set after one torque cycle, and bonded types age with heat. Replacing it each service helps prevent slow leaks and saves over-tightening the plug to “chase” a seal.

What size sump plug washer does the 2013 Ranger use?
PX-series Rangers typically use an M14 washer. Match the original style (copper/aluminium crush or bonded sealing washer) and ensure the inner and outer diameters match the OE spec for proper seating.
