Parts for your 2024 Mitsubishi Eclipse cross-Sump plug washers

2024 Mitsubishi Eclipse Cross sump-plug-washers

Based on Mitsubishi Motors service literature for the Eclipse Cross (GK/GL series, including MY24) and the official Mitsubishi ASA electronic parts catalogue, the engine oil drain plug on the 2024 Mitsubishi Eclipse Cross seals with a replaceable crush washer. That means a sump-plug-washer is fitted and relevant for every scheduled service.

On this model, the sump-plug-washer is the simple, single-use seal that sits between the drain bolt and the sump. When the bolt is tightened, the aluminium (or sometimes copper) washer compresses to form a tight seal, keeping engine oil where it belongs and protecting the sump face from gouging. Without a fresh washer, tiny gaps can allow seepage, which can leave drips on the driveway or, worse, slowly lower oil levels over time.

For the 2024 Eclipse Cross, the best practice is to replace the sump-plug-washer at every oil change, or any time the drain bolt is removed. That lines up neatly with typical service intervals (often 12 months/15,000 km for many Aussie and Kiwi schedules, or as per the owner’s handbook). Reusing a crush washer can seem tempting, but once it’s flattened, it won’t crush again evenly, and that’s when weeping starts. Keep a couple of spares in the glovebox or service kit so one is always on hand when the bonnet’s up.

• Clean the sump face and the drain bolt head before refitting.
• Hand-start the bolt to avoid cross-threading, never force it.
• Fit a new washer of the correct type and size for the Eclipse Cross engine.
• Tighten only to the factory torque spec from the service manual, over-tightening can strip threads.
• Skip thread sealants, a correct, fresh washer does the sealing.
• After the oil change, run the engine, then check for any weeping around the plug.

If there’s a faint oil smell, tiny drips on the undertray, or wetness around the plug, the washer is the first suspect. While many Mitsubishis commonly use a 14 mm aluminium crush washer, owners should match the washer to the 2024 Eclipse Cross by VIN via the dealer or a trusted parts catalogue, as some variants may specify copper or rubber-bonded metal types. Using the right washer every time keeps servicing tidy, prevents headaches, and helps protect the engine for the long haul.

Popular questions about 2024 Mitsubishi Eclipse Cross sump-plug-washers

Can the sump-plug-washer be reused on a 2024 Eclipse Cross?
It’s not recommended. The washer is designed to crush once to create a perfect seal. Reusing it can lead to weeping or drips. In a pinch, a reused washer might get you by, but keep an eye out for leaks and replace it at the next opportunity.

How often should the sump-plug-washer be changed?
Every oil change, or any time the drain bolt is removed. This aligns with typical service intervals in Australia and New Zealand and is also what Mitsubishi service information advises to maintain a reliable seal.

Which washer type fits the 2024 Eclipse Cross?
A crush washer matched to the Eclipse Cross engine specification is required. Many Mitsubishi models use an aluminium 14 mm style, but owners should confirm for their exact VIN/engine variant via the dealer or an official parts catalogue to ensure the correct type and size.
