Parts for your 2017 Haval H6-Oil pump

2017 Haval H6 oil pump — what it does and when to service or replace it

Yes, the 2017 Haval H6 is fitted with an engine oil pump. Technical documentation for the H6’s turbocharged petrol engines (such as the GW4G15B 1.5T and GW4C20-series 2.0T) shows a crankshaft-driven, rotor-type oil pump within the engine’s lubrication system. This is outlined in Haval/Great Wall workshop manuals (Engine Lubrication section), factory engine training materials for the GW4G15B/GW4C20, and the Haval Electronic Parts Catalogue, which lists the complete oil pump assembly, pickup and relief components for the 2017 model. Without this pump, the engine and turbocharger wouldn’t receive pressurised oil, so it’s absolutely relevant to the H6.

The oil pump’s job on a 2017 Haval H6 is simple but vital: it pulls oil from the sump through the pickup, pressurises it, and feeds a steady flow to the crank and rod bearings, camshafts, timing gear, variable valve timing hardware and the turbo. That oil film prevents metal-to-metal contact, carries away heat, and moves contaminants to the filter. In most H6 engines, the pump is a gerotor/trochoid unit driven off the crank, with an internal relief valve to keep pressure in check.

For everyday servicing, the best “maintenance” for the pump is clean, correct-spec oil and a quality filter at the prescribed interval. Many workshops in Australia and New Zealand service these at around 10,000 km or 12 months, always follow the schedule and viscosity spec in the owner’s handbook. Skipping oil changes or using the wrong grade is the quickest way to wear the pump and starve the turbo and bearings.

Owners and techs should watch for tell-tales that point to pump or lubrication trouble:

• Low oil pressure warning or rattly top-end on cold start
• Turbo whine, lifter tick or timing chain noise
• Metallic glitter in drained oil or a clogged pickup screen

If low pressure is suspected, confirm with a mechanical gauge before condemning the pump. If the engine has suffered bearing damage or heavy sludge, the pump, pickup O-ring and relief valve are usually replaced as a set. Replacement is a front cover/sump-off job: clean the pickup, renew seals, apply the correct sealant, prime the new pump with clean oil, and torque to spec. After reassembly, fit a new filter, fresh oil, and verify hot idle and cruise oil pressure. Never drive an H6 with the oil light on — minutes can be enough to damage the turbo and bearings.

Popular questions about the 2017 Haval H6 oil pump

Does the 2017 H6 definitely have an oil pump?
It does. The H6’s turbocharged petrol engines rely on a crank-driven rotor pump for lubrication and turbo feed. Factory service manuals and the Haval parts catalogue list the oil pump assembly, pickup and gaskets for 2017 models.

How long should the oil pump last?
With regular oil and filter changes using the correct grade, the pump generally lasts the life of the engine. Premature wear is usually linked to contaminated or incorrect oil, sludge, or debris after internal engine damage.

Can they keep driving with the oil pressure light on?
No. They should stop the engine immediately and arrange a tow. Running with low oil pressure can quickly damage bearings and the turbocharger, turning a small issue into a major rebuild.
