Cooling system
Engine coolant filling
If the coolant level in the coolant reserve
tank is at or below the MIN line, add
coolant or water to bring it up to the MAX
line. Inspect the cooling system for leaks. In
the adding coolant, the proportion of
coolant and water refers to local practical
temperature, and choose according to the
instructions of coolant adding.
Always use BYD AUTO four-season
antifreeze coolant. Do not need to add any
extender. If this coolant is not available, you
may use another major-brand non-silicate
coolant as a temporary replacement. Make
sure it is a high-quality coolant
recommended for aluminum engines.
Otherwise, continued use any non-BYD
coolant can result in corrosion, and cause
the cooling system to malfunction or fail. So
empty the cooling system as soon as
possible, refill the antifreeze coolant of
BYD AUTO brand. Advice that coolant of
different brands and types can‘t be mixed
used.
If the reserve tank is completely empty, you
should also check the coolant level in the
radiator.
