Parts for your 2018 Haval H6-Exhaust mount

2018 Haval H6 exhaust-mount: purpose, care and when to replace

Referencing the Haval/Great Wall OEM workshop literature for the 2017–2019 H6 exhaust section and the factory illustrated parts catalogue (backed up by common aftermarket parts catalogues), the 2018 Haval H6 is fitted with rubber exhaust mounts (also called hangers or insulators) that suspend the exhaust system from the body. So an exhaust-mount is absolutely relevant and used on this model.

On the H6, these rubber mounts do a few important jobs: they hold the exhaust steady under the car, keep the pipework sitting at the right height and angle, and isolate engine and road vibration so the cabin stays quiet. They also allow a little controlled movement so heat expansion and bumps don’t crack joints, stress the turbo/downpipe area (where fitted), or knock the muffler against the underbody.

Because they live near heat and road grime, the mounts gradually harden, crack, or stretch. When that happens, the exhaust can sag, rattle over bumps, or thump at start-up and shutdown. Left too long, a tired mount can contribute to broken brackets, split welds, or premature flex-joint wear.

• Tell-tale signs: dull thuds or rattles, visible sagging muffler/tailpipe, rubber cracks or tears, shiny witness marks where the exhaust has tapped the body or heat shields.
• Typical lifespan: varies with climate and driving, but it’s smart to check them at every service and expect replacements somewhere around 80,000–120,000 kilometres, sooner if towing or driving on corrugations.
• Best practice: replace any perished or overly soft mount, and consider doing them in pairs/sets so the exhaust sits level. Quality OEM or reputable aftermarket rubber (or high-temp polyurethane) lasts longer.

For servicing or DIY replacement, always work on a cold exhaust. Support the system with a stand or jack pad before removing a mount so weight isn’t hanging off a single point. A quick spray of silicone lube helps the rubber slide on and off the pegs without tearing. After fitment, check clearances to the rear bumper, heat shields, driveshaft (on AWD), and crossmembers, then road test for noise.

Owners doing plenty of gravel work, towing the boat, or living near the coast may see faster ageing thanks to heat cycling, salt, and vibration. A quick look during oil changes can save a bigger exhaust bill later. If in doubt, a workshop can inspect and quote in minutes.

FAQs

How often should exhaust mounts be replaced on a 2018 Haval H6?
There’s no fixed interval, but inspecting them at every service is the go. Many H6s will need fresh mounts somewhere between 80,000 and 120,000 kilometres. If you hear rattles or see the tailpipe sitting off-centre, get them checked sooner.

Is it safe to drive with a broken exhaust mount?
It’ll usually still drive, but it’s not ideal. A missing or torn mount can let the exhaust swing and strike the body, damage sensors or flex joints, and create exhaust leaks. If one’s failed, drive gently and get it sorted promptly.

Are the mounts the same on all H6 variants?
Mount locations are similar, but rubber hardness and shapes can vary by engine, trim and model year. Always match the mount to the VIN or use the old part as a pattern to ensure proper fit and ride height.
