Haval
Model Number:
GW4D20T
One engine code has been built in four forms under the same two-litre diesel badge, and each form carries a different charger with a different supplier figure. The number on the unit belongs to the version, not to the model, so a part ordered against the vehicle name alone is a coin toss. This page separates the four, and separates the diesel from the petrol machine that shares the bonnet.

| Packing | Foam cradle, ports capped, actuator arm secured |
| Four Forms of One Code | The plain engine, the D form, the M form and the T form were released on four different chargers, and the suffixes differ by a single letter that a buyer rarely reads out loud. |
|---|---|
| Diesel Against Petrol | The same body shell was sold with a petrol engine whose charger belongs to an entirely different family, and every marketplace listing blends both because the machine name is identical. |
| One Letter in the Middle | Three vehicle figures in this family share their opening and closing characters and differ only in the last three, which is exactly the section that gets truncated on a chat message. |
| Twin Scroll Is Not Twin Turbo | The divided inlet feeds two runner groups into one wheel, and a buyer who reads the phrase as two chargers will budget for the wrong quantity and then argue about the invoice. |
| Two Numbering Systems | The vehicle maker issues a figure beginning with its own prefix while the charger maker issues a shorter one, and quotations often carry only the second without saying so. |
| Related Components | Cartridge, housing, gasket kit, oil feed pipe, drain pipe, charge hose, air filter, mounting studs. |
Black smoke at low speed on this generation is usually a stuck recirculation valve or a loaded filter, and replacing the charger first is the most expensive way to find that out.
The feed pipe on this engine runs close to the hot side and cokes internally with age, so a new cartridge on an old pipe fails within weeks rather than months.
A split charge hose after the filter passes dust straight to the wheel, and the resulting damage looks like a balance defect on a unit that was sound when boxed.
The boost control arm is set during assembly, and moving it by hand to chase a fault leaves the unit out of calibration with no way back without a bench.
Read the engine plate rather than the vehicle badge, because the four forms share a body and a displacement.
No, the manifold and the oil connections differ.
One, with a divided inlet.
It identifies the version, and it is the part most often mistyped.
Yes, on any engine past its mid life.
Rarely, and only after the air and recirculation paths are proven sound.
