2017 Haval H6 Water Pump — What it does and when to replace it

Technical sources confirm the 2017 Haval H6 is fitted with a conventional engine water pump. The Haval H6 2017 Workshop/Service Manual (Cooling System section), GWM/Haval electronic parts catalogue listings for the GW4C20-series 2.0‑litre turbo engine, and common aftermarket catalogues from major suppliers all show a dedicated water pump assembly for this model.

On the 2017 Haval H6, the water pump’s job is to keep coolant moving through the engine block, cylinder head, turbocharger housing, heater core and radiator. By circulating coolant, it keeps engine temps in the sweet spot, stops hot spots around the turbo after a hard run, and makes sure the cabin heater works on chilly mornings. The pump is a mechanical unit driven by the accessory (serpentine) belt, with an internal bearing and seal designed to handle constant load and heat.

Routine servicing should include a quick look and listen. A healthy H6 water pump doesn’t wobble, grind or weep. If there’s pink/green crust around the pump body or a drip from the weep hole, if the belt squeals, or if the temp needle creeps up in traffic, it’s time to book it in. Coolant smell under the bonnet, poor heater output at idle, or a low coolant level without an obvious hose leak are other tell-tales.

There’s no fixed replacement interval for the pump itself, but it’s smart to inspect it at every service and any time the drive belt is off. When replacing the water pump on a 2017 H6, a good workshop will typically:

• Depressurise and drain the cooling system into a suitable container.
• Remove the serpentine belt and pump pulley, then the pump and gasket/seal.
• Clean the mating surface, fit the new pump with the correct torque and pattern.
• Refit the belt, refill with the specified long‑life coolant mix, and bleed air properly.

Best practice while you’re there: fit a fresh drive belt if it’s cracked or glazed, check the idlers and tensioner, and replace the thermostat if there’s any doubt. Always use the correct long‑life coolant specified for Haval/GWM, mixed with demineralised water, and refresh coolant as per the owner’s manual schedule. Expect around 2–4 hours labour depending on variant and access. After the job, a proper bleed and a thorough road test to confirm stable temps are essential.

These recommendations align with the H6 cooling system procedures in the 2017 Haval service documentation and the part configuration shown in the GWM/Haval EPC for the GW4C20 engine.

Popular questions about 2017 Haval H6 water pumps

How do you know the water pump is failing on a 2017 H6?
Common signs include coolant seeping from the pump body or weep hole, a grinding or rumbling noise from the front of the engine, wobble at the pump pulley, rising engine temperatures in traffic, or a sweet coolant smell. If the heater goes cold at idle but warms up at higher revs, circulation may be weak.

Should the water pump be changed with the drive belt?
Not automatically, but it’s convenient to assess both together. If the H6 has higher kilometres, the pump shows the slightest leak or bearing play, or the belt and tensioner are due, doing the pump at the same time can save repeat labour and keep the cooling system reliable.

What coolant type and capacity should be used?
Use the Haval/GWM‑approved long‑life ethylene glycol coolant and mix it with demineralised water to the specified ratio. Capacity is roughly in the 7–8 litre range depending on variant, but always check the owner’s manual or parts data for the exact fill and bleeding procedure.
