Parts for your 2022 Haval H6-Sump plug washers

2022 Haval H6 sump-plug-washers

Technical sources indicate the 2022 Haval H6 does use a sump-plug-washer on the engine oil drain plug. This is shown in the GWM/Haval H6 (B01) workshop manual’s Engine Lubrication section, where the drain plug is illustrated with a replaceable sealing washer, it’s also noted in dealer EPC listings for the H6 that the drain plug gasket is a separate service item. Australian and New Zealand aftermarket catalogues (e.g., Tridon sump plug and washer finder and major parts retailers’ fitment guides for 2021–on H6) likewise specify a crush or bonded washer for the H6 drain plug.

For the 2022 Haval H6, the sump-plug-washer is the small but mighty seal that sits under the engine’s oil drain plug. Its job is simple: when the plug is tightened, the washer deforms slightly to create a tight seal between the plug and the sump, stopping those annoying seeps and drips. Whether the H6 is the 2.0‑litre turbo petrol or the hybrid with a petrol engine, both rely on a healthy washer to keep the engine bay tidy and the driveway free of oil spots.

During servicing, this little ring deserves a spot on the to-do list. Most H6 variants use a single-use crush washer (often aluminium or copper) or a bonded sealing washer. Crush types should be replaced at every oil change because they’re designed to deform once, reusing them can lead to weeping around the plug or the temptation to overtighten. Bonded styles can sometimes be reused if they’re perfectly clean and undamaged, but given how affordable they are, most techs will pop in a new one for peace of mind.

Best practice for an H6 service is straightforward: remove the plug, discard the old washer, wipe the mating surface on the sump, and fit the correct new washer matched to the factory plug. Avoid sealants—they can interfere with the seal and shed debris into the oil. Tighten the plug to the workshop-specified torque and check for leaks after the first start-up. If there’s any sign of seepage, don’t crank the plug harder, inspect the washer and sealing face instead.

Signs it’s time for a fresh washer include oil misting around the plug, a flattened or gouged washer, or needing more effort than usual to get the plug to seal. Keeping a couple of spare washers on hand makes every H6 oil change quicker, cleaner, and kinder to the sump threads.

Popular questions about 2022 Haval H6 sump-plug-washers

Do you need to replace the sump-plug-washer at every oil change on a 2022 Haval H6?
Yes, if it’s a crush-style washer it’s considered single-use and should be replaced at each oil change. If the H6 has a bonded washer and it’s clean and undamaged, some technicians may reuse it—but most will still fit a new one to guarantee a leak-free seal.

How can you tell if the sump-plug-washer on an H6 needs replacing?
Look for oil weeping around the drain plug after a service, visible scoring or flattening of the washer, or any sealing face damage on the sump. If you’re tightening the plug correctly and it still won’t seal, the washer is the first thing to swap.

Which washer type should be used on the 2022 H6?
Use the washer style and size specified for the factory drain plug on your exact H6 variant. AU/NZ parts catalogues list a crush or bonded sealing washer for the model—match by VIN or plug size to ensure proper fit and sealing.
