Parts for your 2022 Haval H6-Drive belt pulley

2022 Haval H6 Drive-Belt Pulley — What’s Fitted and What To Look After

Based on GWM/Haval technical material, a drive-belt pulley is used on 2022 Haval H6 petrol variants, but generally not on the H6 Hybrid (HEV). The H6 petrol engines (GW4B15A 1.5T and GW4N20 2.0T) are shown in the H6 Service Manual and Electronic Parts Catalogue with a serpentine accessory belt, automatic tensioner and idler pulleys driving the alternator and A/C compressor. By contrast, GWM’s L.E.M.O.N. DHT hybrid technical overview describes electric accessories (electric A/C compressor, electric water pump and DC–DC converter in place of a conventional alternator), meaning no external accessory belt or pulleys on the HEV. So, drive-belt pulleys are relevant for 2022 H6 petrol models, but typically not for the hybrid.

For owners of the 2022 Haval H6 petrol, the drive-belt pulley setup is a simple bit of kit that keeps daily motoring drama-free. The crankshaft spins a multi-rib (serpentine) belt, and that belt rides over a series of pulleys — the alternator, A/C compressor, and one or more idler and tensioner pulleys — to keep the electrics charging and the cabin cool. When the pulleys and belt are in good nick, everything under the bonnet runs smooth and quiet.

As part of routine servicing, the belt and pulleys deserve a quick once-over. Under typical Aussie and Kiwi conditions, a visual inspection every service (around 10,000–15,000 km) is a smart move, with many workshops recommending belt replacement somewhere between 90,000 and 150,000 km or earlier if there’s visible wear. Idler and tensioner pulleys can wear at a similar pace to the belt, swapping them as a set with the belt avoids repeat labour and keeps squeaks at bay.

What to watch and listen for:

• Chirping or squealing on cold start or when the A/C kicks in
• Belt cracks, fraying, glazing or missing ribs
• Pulley wobble, roughness, or a grinding/whirring bearing noise
• Intermittent battery light or weak charging

If any of that pops up, it’s worth getting a tech to check belt tension, pulley alignment and bearing condition. The automatic tensioner should move smoothly and hold firm, if it’s weak or jumpy, replace it along with the belt. Using the correct spec belt length and rib profile for the exact H6 engine code is essential, and a new belt should run centrally on each pulley without walking. After any replacement, a short recheck for noise, tracking and charging voltage will confirm it’s all sorted.

For the 2022 H6 Hybrid, none of this typically applies because its accessory systems are electric and beltless — there’s no conventional alternator or A/C belt to service. Hybrid owners should instead follow the factory maintenance schedule for the high-voltage and cooling systems specified in GWM’s DHT documentation.

Popular questions

How often should the H6’s drive belt and pulleys be replaced?
For 2022 H6 petrol models, many workshops inspect the belt and pulleys every service and replace the belt around 90,000–150,000 km, or sooner if there’s wear or noise. It’s common to replace the automatic tensioner and any idler pulleys at the same time to avoid repeat visits.

What are the tell-tale signs a pulley or the belt is failing?
Squeals, chirps, or a grinding/whirring noise near the front of the engine are common. Visible belt cracks, fraying or glazing, pulley wobble, or an intermittent battery warning can also point to a tired belt or a rough pulley bearing.

Does the 2022 Haval H6 Hybrid have a drive-belt pulley?
Generally no. The HEV’s L.E.M.O.N. DHT system uses electric accessories and a DC–DC converter in place of a belt-driven alternator, so there’s typically no external accessory belt or pulleys to service on the hybrid.
