GW4D20B 2.0T Diesel Bare Engine / Long Block – Great Wall & Haval Replacement Engine

This GW4D20B bare engine is a complete long block assembly built to OEM specifications for Great Wall and Haval vehicles. It is the 2.0-litre common-rail turbo diesel from the GW4D20 engine family, and this specific version is the transverse-mounted variant used in the Haval H6 and related SUVs. The block, head, crank, pistons, camshafts and valves are all in place, and the assembly is ready to accept your existing intake, exhaust, turbocharger and accessories. This is the same engine that powered a large share of Great Wall pickups and SUVs through the 2010s, and it is still one of the most common diesel engines in the aftermarket for these vehicles.

Vehicle Compatibility

The GW4D20B engine has been fitted to a range of Great Wall and Haval models. Always verify your engine code “GW4D20B” before purchase. Common applications include:

• Great Wall Wingle 5 2.0T diesel (2010 – 2021, including European version and double cab variants)
• Great Wall Wingle 6 2.0T diesel (2014 – 2021)
• Haval H5 2.0T diesel (2011 – 2016, including 4WD and classic editions)
• Haval H6 2.0T diesel (2011 – 2020, including Hover H6)

Please confirm your engine code is “GW4D20B” before ordering. This is the transverse-mounted variant, which is why it is mostly found in the H6 and related SUVs. The GW4D20 (without the B) is the longitudinal version used in the H5 and Wingle pickups. They share the same block architecture but the mounting and accessory layout differ. This is a bare engine assembly; all external components must be transferred from your original engine.
