GW4D20D Engine for Great Wall Haval accessories

2.0L Turbo Diesel Engine GW4D20D/GW4D20B for Great Wall Wingle 7 & Hover H6 – High-Performance Powertrain Replacement

This professionally engineered 2.0L turbocharged diesel engine assembly is designed specifically for the Great Wall Wingle 7 (since 2018) and Hover H6 models, offering reliable power delivery and improved fuel efficiency. The GW4D20D and GW4D20B variants are proven units from Great Wall Motors, widely used in commercial and off-road applications where durability and torque performance matter most. Whether you're restoring a classic model or upgrading your existing drivetrain, this engine offers OEM-level compatibility with enhanced longevity when maintained correctly.

Key specifications include a peak output of 105 kW (143 hp) at 4,000 rpm and maximum torque of 315 Nm between 1,400–2,800 rpm—ideal for towing, highway cruising, and rugged terrain. Compared to older naturally aspirated engines like the 4G63S4T found in some Haval H5 variants, the GW4D20D delivers significantly more low-end grunt and smoother acceleration, making it an excellent choice for drivers seeking responsive performance without sacrificing reliability.

The long block engine design ensures easy installation while maintaining structural integrity, reducing downtime during vehicle rebuilds. It's suitable for both complete engine swaps and partial overhauls, especially when paired with high-quality oil systems and modern filtration components. For optimal operation, use premium-grade diesel engine oil rated at least CB or CD level—never compromise on lubricant quality to protect internal bearings, pistons, and turbocharger components.

Common maintenance practices include regular oil changes using synthetic or semi-synthetic formulations compatible with diesel engines, as well as timely replacement of air filters, fuel injectors, and coolant systems. These steps help prevent carbon buildup, reduce wear, and extend service intervals beyond 100,000 kilometers under normal driving conditions. This engine also benefits from periodic ECU calibration checks, particularly after major repairs or component replacements.

Designed for global markets outside China, including Europe, North America, Australia, and South America, this unit meets international emissions standards and is ideal for owners of Great Wall vehicles who require a durable, high-torque solution for daily commuting, light-duty hauling, or recreational off-roading. Its robust construction makes it suitable for both urban environments and remote locations where access to professional mechanics may be limited.

Users report consistent performance even in extreme temperatures—from -20°C winter climates to +40°C desert conditions—thanks to its advanced thermal management system and reinforced cylinder head design. Many have noted improved throttle response and reduced noise levels compared to stock configurations, especially after installing aftermarket intercoolers and upgraded exhaust manifolds.

Q: Is this engine compatible with other Great Wall models? A: While primarily intended for the Wingle 7 and Hover H6, it can sometimes be adapted to similar platforms such as the Fengjun 5 with minor modifications to mounting brackets and wiring harnesses. Always verify compatibility before purchase.

Q: What type of oil should I use? A: Use diesel engine oil rated at least API CB or CD standard. Higher grades like CF or CE are recommended for extended lifespan and better protection against soot contamination.

Q: How often should I change the oil? A: Follow manufacturer guidelines—typically every 10,000 km or annually, whichever comes first. More frequent changes may be needed if operating in dusty or high-load conditions.
