BYD DOLPHIN: Coolant below MIN or abnormal coolant loss
Symptoms
- The coolant level is below MIN, with possible continuing loss. [1]
Possible causes
- The manual requires checking the cooling system for leaks when the level is low; it does not identify a specific failed component. [1]
Checks
- Only check the level after the system has fully cooled; have a qualified technician check for leaks if coolant loss continues. [1]
What to do
- Use the corresponding specification and identify the cause; do not open the cap when hot or invent a water pump fault. [1]
Applicability and limits
- Only applies to the corresponding DOLPHIN configuration in the New Zealand English-language owner's manual; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to vehicles with the same model name, other powertrains or other markets. Scope: unknown [1]
- Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name.
