Additional Notes
- The BYD E5 450 carries a coolant capacity of 3.5 liters for the electric motor cooling system, a figure consistent with the relatively compact thermal management circuits found in passenger electric vehicles compared to larger commercial electric platforms.
- The 3.5-liter capacity listed for the 2018-2022 E5 450 applies specifically to the electric motor cooling circuit, which is a separate loop from any cabin heating or battery thermal management that may exist in the vehicle architecture.
- A change interval of 10,000 km or 48 months is specified under normal use conditions for the E5 450 cooling system, meaning the time-based limit of 48 months can trigger a service even when the distance threshold has not been reached.
- The 48-month time interval tied to the E5 450 coolant service reflects a standard practice for electric vehicle coolant maintenance, where degradation of corrosion inhibitors over time is a primary driver of replacement rather than mileage alone.
- A single specification row covers the full 2018-2022 production span of the E5 450, indicating no variation in coolant capacity or service interval was introduced across those model years for the electric motor cooling system.
