Haval H2's engine is independently developed and produced by Great Wall Motors, belonging to a domestically manufactured engine. The engine model of Haval H2 is GW4G15B, with a maximum horsepower of 150, a maximum power of 110kW, and a maximum torque of 210Nm. For daily maintenance of the Haval H2 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid failures, oil should be changed regularly according to usage conditions, and the oil level should be kept moderate; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking the filter and oil holes, making engine lubrication difficult and causing wear.; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine works properly but also extends the overall lifespan of the radiator and engine.
