Parts for your 2019 Haval H6-Thrust bearing

2019 Haval H6 thrust bearing — what it does, and when to sort it

Based on factory documentation and parts catalogues for the 2017–2020 Haval H6 with the GW4C20/GW4C20B 2.0‑litre turbo petrol engine, a thrust bearing is definitely used on this vehicle. The H6 engine integrates crankshaft thrust faces into the main bearing set to control end float, as described in Haval/Great Wall workshop manuals and engine repair guides, and supported by OE-style bearing listings from major suppliers that specify “main bearings with thrust” for this engine family. On H6 variants fitted with a dual‑clutch transmission, the clutch module also employs internal release/thrust bearings, though these are serviced as part of the clutch assembly rather than as a standalone item.

For owners, that means the H6 absolutely relies on a thrust bearing inside the engine to keep the crankshaft from walking fore and aft under load. It takes axial loads from the timing drive, accessory belts and gearbox interaction, keeping the crank spinning in a straight line so oil clearances, timing and sealing all stay happy. When it’s doing its job, you’ll never know it’s there.

It’s not a regular service item, but it does appreciate clean, correct‑spec oil and timely changes. That thin oil film is the only thing between the crank’s thrust faces and the bearing, so stretched oil intervals, the wrong viscosity, or contamination can accelerate wear. If an H6 ever shows axial play at the crank pulley, a dull knock when loading the crank (older manuals show this when the clutch is pressed, if fitted), unusual belt misalignment, or metallic glitter in the oil, it’s time for a professional check of end float.

Replacement isn’t a quick Saturday job. On the H6, the sump and bearing caps need to come off, and the crank is inspected and measured. A technician will select the correct bearing grade, check clearances with plastigauge, verify crank end float to spec, and torque new fasteners to the book. It’s commonly bundled with an overhaul if there’s journal wear. Parts are modest in cost, labour is the big ticket, as the engine may need to come out depending on workshop approach.

Good habits help the thrust bearing live a long life: stick to quality oil and filters, fix any low oil pressure or overheating issues promptly, and avoid prolonged lugging under heavy load. For DCT H6s, smooth take‑offs and software updates that improve clutch control also reduce unnecessary axial shock into the crank.

• Use the correct oil grade and change on time.
• Address oil leaks, low pressure warnings, or overheating immediately.
• Have end float checked if noises or pulley movement appear.

Popular questions about the 2019 Haval H6 thrust bearing

Does a 2019 Haval H6 actually have a thrust bearing?

Yes. The GW4C20/GW4C20B engine in the H6 uses an integrated crankshaft thrust bearing as part of the main bearing set. Dual‑clutch models also have internal release/thrust bearings inside the clutch module, but those aren’t typically serviced on their own.

What are the warning signs of a worn thrust bearing on an H6?

Look for axial movement at the crank pulley, a dull knock when the crank is loaded, belt misalignment, or metallic flakes in the oil. Any of these warrant an end‑float measurement and an oil system health check. Catching it early can save the crankshaft.

How much does thrust bearing replacement cost on a 2019 H6?

Parts are relatively inexpensive, but labour can be significant because the lower end of the engine must be opened and everything measured precisely. Expect a wide spread depending on workshop method and what’s found—if the crank needs machining or additional bearings, costs rise. A proper estimate requires inspection.
