Understanding these specifications helps in maintaining the transmission system effectively, preventing issues such as transmission slipping or overheating.

Engine Models and Specifications

Each BYD Qin model is equipped with a specific engine type that dictates its performance and maintenance needs. The 1.5L Turbocharged Inline-4 engine is common across the Qin Pro, Qin Plus, and Qin L models, with variations in power output and torque depending on the combination with electric motors in PHEV versions. Regular oil changes with the recommended 5W-30 oil are crucial for maintaining engine health and performance.

Other Fluid Capacities

Apart from engine oil and transmission fluid, other critical fluids include coolant, brake fluid, and power steering fluid. The coolant capacity for all BYD Qin models is 6.0L, with a specification of ethylene glycol-based pre-mixed 50/50. Brake fluid capacity stands at 1.0L, specified as DOT 4, and the power steering fluid, if applicable, also has a capacity of 1.0L, specified as ATF Dexron II. Regular checks and top-ups of these fluids are necessary to ensure the smooth functioning of the vehicle’s systems.

Maintenance Schedule

A well-defined maintenance schedule is essential for the BYD Qin to operate efficiently and reliably. The schedule includes regular replacement of engine oil and filters every 10,000 km or six months, checking and topping up brake fluid and coolant, and replacing transmission fluid every 40,000 km or 24 months. Additionally, air filters, cabin air filters, and spark plugs should be inspected and replaced every 20,000 km or 12 months, while the timing belt and power steering fluid require attention every 60,000 km or 36 months. Adhering to this maintenance schedule prevents premature wear and tear and ensures the longevity of the vehicle.
