Parts for your 2019 Haval H6-Oil pump

2019 Haval H6 oil pump — what it does and how to look after it

Yes, the 2019 Haval H6 is fitted with an engine oil pump. This is confirmed in Haval’s workshop/service literature for the H6 (Lubrication System section), the Great Wall Motor electronic parts catalogue (EPC) which lists the oil pump assembly for 2019 H6 petrol turbo engines, and the 2019 H6 Owner’s Manual that references oil pressure and lubrication warnings. Together, those technical sources make it clear the oil pump is a standard, essential component on this model.

The oil pump’s job is simple but critical: it pushes engine oil under pressure through the galleries to bearings, camshafts, timing components and the turbocharger, keeping everything lubricated and cool. On a modern turbo petrol H6, the pump is driven off the crankshaft and regulated by a relief/pressure control system so the engine gets the right flow from cold start through to highway cruising.

Looking after it is mostly about good oil hygiene. Fresh, correct-spec oil and a quality filter at each service protect the pump and the rest of the engine. Follow the intervals in the owner’s book (commonly every 10,000–15,000 km or 12 months in ANZ conditions, whichever comes first), and always use the grade and specification Haval calls for.

• Watch for trouble signs: low oil-pressure warning, rattly top-end on cold start, turbo whine, metallic glitter in drained oil, or persistent ticking after an oil change.
• If any of the above shows up, don’t keep driving — low pressure can quickly damage bearings and the turbo.

Replacement isn’t a routine item, it’s done when diagnostics confirm a pressure problem, the pickup is blocked or damaged, or during an engine rebuild. On many H6 engines the pump sits behind the front cover or integrates with a module, so the job typically involves draining oil, removing the sump and front cover, inspecting/cleaning the pickup strainer, fitting a new pump with fresh seals/O-rings, and torquing fasteners to spec. Priming the new pump with clean oil before refitting helps it build pressure on first start.

Good workshops will also check the pressure relief valve, oil control solenoids (if fitted), and verify hot-idle oil pressure with a mechanical gauge after the repair. For most owners, the smartest play is sticking to quality oil and filters, keeping to service intervals, and jumping on any oil-pressure warnings straight away.

Popular questions about 2019 Haval H6 oil pumps

Does the 2019 Haval H6 have an oil pump?
Yes. All 2019 H6 internal-combustion engines use a crank-driven oil pump as part of the pressurised lubrication system. It feeds bearings, valvetrain and the turbo, and is monitored by the oil-pressure warning system.

When should the oil pump be replaced?
There’s no set interval. It’s replaced when diagnostics show low oil pressure, internal pump wear/damage, sludge-contaminated pickup, or during an engine rebuild. Rule out simple causes first: low oil level, wrong viscosity, clogged filter, or a faulty pressure sensor.

What oil helps protect the pump in a 2019 H6?
Use a full-synthetic oil in the grade and specification listed in the owner’s manual (commonly 5W-30 or 5W-40 meeting the required API/ACEA spec). Change oil and filter on time, and consider shorter intervals if doing frequent short trips or towing in hot conditions.
