The engine of the Roewe i5 is produced by SAIC Motor's engine manufacturing base and is a domestically made engine. The 1.5L version of the Roewe i5 uses the engine model 15S4C, with a maximum horsepower of 120 HP, a maximum power output of 88 kW, and a maximum torque of 150 Nm. The 1.5T version uses the engine model 15C4E, with a maximum horsepower of 173 HP, a maximum power output of 127 kW, and a maximum torque of 275 Nm. For daily maintenance of the Roewe i5 engine, the following methods can be applied: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the engine oil and oil filter. The quality of any lubricating oil will degrade over time. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or activate the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication system, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. In small amounts, sludge remains suspended in the oil, but in large quantities, it precipitates and clogs filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the lifespan of both the radiator and the engine.
