Chinese pickup Great Wall King Kong often exhibits symptoms of overheating in the exhaust gas recirculation (EGR) system during prolonged operation under load, which is directly related to the design features of the heat exchanger. Owners of a model with a 2.8-liter diesel engine periodically record a loss of traction at high speeds, which requires an immediate check of the vacuum line and the condition of the turbocharger. Ignoring the primary signs of EGR valve contamination leads to rapid coking of the intake manifold and the need for expensive mechanical cleaning.
Vehicle operation Great Wall King Kong requires strict quality control of the fuel system, since the injection pump is sensitive to impurities in diesel. Unlike more modern analogues, a classic mechanical circuit is installed here, which is easier to repair, but requires regular adjustment of the injection phases. Untimely replacement of fuel filters causes a drop in pressure in the rail and difficult starting in winter.
Visually, the model is a classic truck with a frame structure, where the body is separated from the side members by rubber-metal cushions. It is these elements that are the first to fail during frequent off-road driving, causing characteristic creaking and body vibrations. Checking the condition of the suspension and spring fastenings should be carried out regularly, since overloading the rear axle is a typical mistake when operating this commercial vehicle.
Engine and technical specifications
The basis of a pickup truck's power plant Great Wall King Kong is the GW2.8TC turbodiesel unit, which has proven itself to be a reliable but noisy “worker”. The engine develops 95 horsepower and 225 Nm of torque, which is an average figure for a frame truck with a gross weight of about 2.5 tons. Turbocharger here it provides a boost sufficient for city use and moderate off-road use, but on the highway the acceleration dynamics leave much to be desired.
The engine design is of the OHV type (valves in the head, camshaft in the block), which makes it easy to maintain and repairable in the field. The absence of complex phase shifters and hydraulic compensators requires periodic manual adjustment of the thermal clearances of the valves. Neglecting this procedure leads to increased noise when idling and decreased compression in the cylinders.
The lubrication and cooling system requires the use of strictly regulated materials, since the gaps in the friction pairs are designed for a certain oil viscosity. For this engine, it is critical to maintain oil change intervals, not exceeding 8,000 km, especially when operating in difficult conditions.
To extend the life of the turbine on the GW2.8TC engine, turn off the engine only after 2-3 minutes of idling to prevent the oil from coking in the shaft bearings.
The table below shows the main technical parameters of the power unit:
| Parameter | Meaning |
|---|---|
| Engine type | Diesel, turbocharged |
| Working volume | 2771 cc cm |
| Power | 95 hp at 3600 rpm |
| Torque | 225 Nm at 1800 rpm |
| Ecological class | Euro-3 / Euro-4 |
Transmission and drive
Pickup transmission group Great Wall King Kong is based on a 5-speed manual gearbox, which is coupled with a two-speed transfer case. This combination provides the ability to connect all-wheel drive Part-Time, which means constant rear-wheel drive and short-term engagement of the front axle only on slippery surfaces. A manual transmission has a long lever stroke and requires clear but strong shifts.
The transfer case is controlled by a lever located next to the driver and does not have a center differential. This places limitations on the use of four-wheel drive on asphalt, as "power leakage" may occur, leading to gear failure or axle shaft rupture. When engaging the front axle, it is necessary to depress the clutch, although experienced drivers often do this while driving at low speeds.
⚠️ Attention: It is strictly forbidden to engage all-wheel drive (4WD) mode on dry hard surfaces. This will lead to accelerated tire wear and damage to the transmission due to the lack of a center differential.
Cardan shafts are protected by plastic casings, which over time lose their elasticity and crack. It is recommended to periodically inspect the condition of the crosspieces and outboard bearings, since play in the cardan is transmitted to the body by vibration. Transfer case and gearbox seals are prone to sweating with a mileage of over 100 thousand kilometers, which requires sealant and replacement of seals.
Suspension and chassis
The chassis is made according to the classic design for frame trucks: an independent torsion bar suspension on double wishbones is installed at the front, and a dependent spring suspension at the rear. This arrangement provides high load capacity and maintainability, but sacrifices comfort when the body is empty. Rear springs tend to sag under constant overload, so many owners install additional leaves or polyurethane spacers.
In the front suspension, the main elements that require attention are the control arm bushings and ball joints. When knocking occurs on the front axle, the first thing to check is these components, as well as the condition of the torsion bars and their fastenings. Adjustment of body height and headlight angle is done by tightening the torsion bars, which allows you to compensate for the subsidence of the front part.
The steering is equipped with a hydraulic booster, the hoses of which are located near the hot elements of the engine. Over time, rubber lines may lose their tightness, so visual inspection of the condition of the power steering tubes is mandatory during each maintenance. Play in the steering mechanism is often eliminated by adjusting the gearing or replacing the rod ends.
- 🛠️ Regular lubrication of the steering knuckle pins extends their service life and prevents squeaking when turning the wheels.
- 🔧 Checking the tightening of the spring ladders is necessary after the first 1000 km of driving on a new car or after replacing the springs.
- 🚛 The use of reinforced shock absorbers improves the behavior of the car when driving with a full load in the body.
Typical faults and their elimination
Among the most common problems Great Wall King Kong The failure of the engine control system sensors is highlighted. The crankshaft position sensor and boost pressure sensor often become dirty or lose contact, which causes the engine to go into emergency mode. Diagnosis of such faults usually reads error codes indicating an open circuit or an incorrect signal.
The cooling system is also a vulnerable point, especially the radiator and pipes. Plastic radiator tanks can crack due to temperature changes, and the thermostat often gets stuck in the closed position, causing rapid overheating. Replacing the thermostat with an analogue with a lower opening temperature sometimes helps stabilize the temperature in hot weather.
The secret to turbine longevity
Monitor the condition of the air filter. Dust on the turbocharger impeller causes shaft imbalance and destruction of the plain bearings. Change the filter more often than required if you drive on dusty roads.
The electrical part of the car is assembled quite simply, but the quality of the wire insulation leaves much to be desired. Oxidation of contacts in headlights and taillights is a common cause of failure of lighting devices. To prevent problems, it is recommended to treat the connectors with contact lubricant and check the ground on the body.
Fuel consumption and efficiency
Real diesel fuel consumption Great Wall King Kong greatly depends on driving style and vehicle load. In the urban cycle with frequent stops and traffic jams, diesel fuel consumption can reach 13-14 liters per 100 km. This is due to the large mass of the car, the aerodynamics of the “brick” and the settings of the fuel equipment.
On the highway at a speed of 90-100 km/h, consumption drops to 9-10 liters, which is an acceptable figure for a frame pickup. However, an increase in speed to 120 km/h and above leads to a sharp increase in fuel consumption due to high drag. Economical driving of this car involves driving at low revs in the torque range.
The fuel tank capacity is about 70 liters, which provides a range of more than 600 kilometers on the highway. The quality of fuel filtration in the standard version is satisfactory, but installing an additional separator in front of the injection pump will significantly increase the reliability of the fuel system.
- ⛽ The use of winter diesel fuel or anti-gel is necessary at temperatures below -5°C to avoid waxing of the fuel.
- 📉 Reducing speed from 110 to 90 km/h reduces fuel consumption by about 15-20%.
- 🔍 Regular checking of injectors at the stand helps to identify overflow and adjust consumption.
Cost of ownership and spare parts
One of the main advantages of the model is the availability of spare parts on the market. Engine GW2.8TC is unified with many Chinese analogues, and the mechanical components (gearbox, transfer case, axles) have a simple design. The cost of a standard hour in specialized services is lower than for European or Japanese competitors, which reduces the final cost of ownership.
Body parts such as bumpers, fenders and optics are also available, but their quality may vary from manufacturer to manufacturer. Original Great Wall parts have better geometry, while analogues may require adjustment during installation. The paintwork of the body is prone to chipping, so it is recommended to install additional protection for the arches and sills.
⚠️ Attention: When purchasing a used vehicle, carefully inspect the frame for corrosion, especially in the areas where the body and springs are attached. Hidden pockets of rust can be a critical issue during inspection.
