Parts for your 2010 Holden Barina-Sump plug washers

2010 Holden Barina sump plug washers

Based on technical references, a sump plug washer is used on the 2010 Holden Barina (TK). Holden/GM service information for the 1.6‑litre petrol engine specifies refitting the engine oil drain plug with a new sealing washer during oil changes and torquing the plug to spec. Haynes’ Chevrolet Aveo/Kalos (the Barina’s twin) service manual also instructs replacing the drain plug gasket at every refit. In Australia and New Zealand, Tridon’s application catalogue lists M14 sump plug sealing washers and compatible drain plugs for Barina TK (circa 2005–2011), confirming a washered plug is fitted. In short, if it’s a TK Barina, there’s a sealing washer on the sump plug—either a crush type (copper/aluminium) or a bonded/semi-captive gasket on the plug.

The sump plug washer on a 2010 Holden Barina does a deceptively important job. It’s the soft, sacrificial seal that sits between the sump and the drain plug, stopping hot engine oil from weeping out once the plug’s tightened. Because the washer deforms a touch when torqued, it takes up tiny surface imperfections and maintains a seal through heat cycles, vibration, and pressure changes. That’s why most technicians swap it at each service rather than chancing a slow leak down the driveway.

On the Barina TK, owners will typically encounter either a replaceable crush washer (M14) or a drain plug with an integrated/bonded gasket. If it’s the crush type, fit a new washer every oil change. If it’s the bonded style and the rubber face is nicked, flattened, or hard, replace the whole plug. Mixing old, flattened washers with fresh torque is what leads to seepage.

Good practice during servicing:

• Inspect the sealing face on the sump for burrs or old washer material, wipe it clean before refitting.
• Use the correct torque (around 30 N·m is typical for this platform—follow the factory spec for your exact engine/code).
• Avoid thread sealants, the washer is the seal. If threads are damaged, repair or replace the plug/pan.
• After the first drive, check for a faint oil ring around the plug—any dampness means the washer or torque needs attention.

Choosing parts is straightforward: quality copper or aluminium crush washers suit most TK Barinas with an M14 x 1.5 plug, while bonded-gasket plugs come ready to fit. Keeping a small pack of washers on hand turns oil changes into a clean, drama-free job, and helps protect the sump threads from over-tightening by relying on the washer to do the sealing.

Popular questions about 2010 Holden Barina sump plug washers

What size sump plug washer does the 2010 Barina use?
The TK Barina commonly uses an M14 washer with a 1.5 thread pitch on the drain plug. If the vehicle has a bonded-gasket drain plug, the seal is integrated—replace the plug if the gasket is damaged. When in doubt, match the new washer to the old one or check the plug size stamped on the replacement plug packaging.

How often should the sump plug washer be replaced?
Best practice is to replace the washer at every oil change. Crush washers are designed to deform once for a perfect seal. Reusing them risks small leaks. If the Barina’s plug uses a bonded seal, replace the plug when the gasket shows wear, flattening, or cracking.

What are the signs the washer needs replacing?
Look for a light oil film or drip forming at the drain plug after a drive, the smell of hot oil, or spots on the driveway under the sump area. On removal, a washer that’s deeply grooved, hard, or misshapen is ready for the bin. If the plug needs more and more torque to seal, the washer’s past its best.
