Checking the engine coolant level
Look at the see-through coolant reservoir
when the engine is cooled. The coolant
level is satisfactory if it stays between the
“FULL” and “LOW” lines on the reservoir.
Upon a lower level, add the coolant. For
the coolant type, see “Coolant type
selection” described below.
The coolant level in the reservoir varies with
the engine temperature. However, if the level
goes above or below the “LOW” line, you
should add coolant to bring the level up to the
“FULL” line.
If the coolant level drops within a short time
after replenishing, there may be a leak in the
system. Visually check the radiator, hoses,
radiator cap and drain cock and water pump.
If no leak is found, contact your BYD AUTO
service station to test the cap pressure and
check whether the cooling system is leaking.
CAUTION
To prevent burns, do not remove the
radiator cap when the engine is hot.
Coolant type selection
Only use the coolant approved by BYD
AUTO and choose suitable coolant according
to the temperature.
Use improper coolant will destroy the engine
cooling system.
CAUTION
Do not use too much plain water in
winter, because engine cooling
system would be damaged in this way.
For details, please contact your BYD AUTO
service station.
