Parts for your 2015 Holden Captiva 5-Sump plug washers

2015 Holden Captiva 5 sump plug washers

Based on Holden/GM Global Service Information for CG Series II (Captiva 5/Opel Antara), ACDelco/GM parts catalogues, and Australian application guides from Penrite, Ryco and Tridon, the 2015 Holden Captiva 5 uses a replaceable sump plug sealing washer on its engine oil drain plug (commonly an M14 x 1.5 plug). So yes—sump plug washers are relevant and fitted to this vehicle.

The sump plug washer is a small but crucial seal that sits under the head of the drain plug. On the Captiva 5 it’s typically a soft aluminium crush washer or a bonded rubber/metal type. Its job is simple: deform slightly as the plug is tightened to create a leak-free seal between the plug and the sump. Without a good washer, the plug can seep, weep under vibration, or be overtightened in a bid to stop drips—risking stripped threads in the alloy sump.

During regular servicing, treating the sump plug washer as a consumable is the go. Most workshops replace it at every oil change, and that’s smart practice for Captiva 5 owners too. They’re inexpensive, and fresh oil plus a fresh washer helps keep the underside clean and the driveway free of spots. If reusing in a pinch, inspect closely: an aluminium washer that’s deeply grooved, flattened, or distorted won’t reseal properly, a bonded type with nicks or a hardened insert should be binned.

When fitting, clean the mating face on the sump and the plug, pop on the correct washer type and size for the Captiva 5, then tighten the plug to the factory spec (typically around 30–35 Nm for many GM M14 plugs—always check the specific service data for the exact engine code). After the oil change, run the engine, wipe the area, and recheck for any misting or drips.

Handy tips for Captiva 5 sump plug washers:

• Replace the washer at each oil change interval.
• Match the washer to the plug size and style (crush vs bonded).
• Avoid overtightening, use a torque wrench and spec.
• If a leak appears, don’t just crank the plug tighter—inspect and replace the washer first.

Treating the sump plug washer as part of routine maintenance keeps the 2015 Captiva 5 tidy, leak-free, and easy to service next time.

Popular questions

What size sump plug washer does a 2015 Holden Captiva 5 use?
Most Captiva 5 engines use a washer to suit an M14 x 1.5 drain plug. Depending on engine variant and plug style, it may be a plain aluminium crush washer or a bonded rubber/metal type. It’s best to confirm by VIN or by matching the old washer at the parts counter.

How often should the sump plug washer be replaced on a Captiva 5?
Replace it at every oil change. It’s cheap insurance against leaks, and many workshop schedules list the washer as a consumable alongside the oil filter. If you must reuse, only do so after a careful inspection for grooves, flattening, or damage.

What torque should the drain plug be tightened to?
For many GM M14 drain plugs, the typical range is about 30–35 Nm. Always refer to the Holden/GM service data for the exact engine in the 2015 Captiva 5. Using a torque wrench helps avoid stripped threads and ensures the washer seals correctly.
