MAINTENANCE
Cooling System
Adding or Changing Coolant
To ensure that the coolant maintains its ability to protect the engine, we recommend that the system be completely
drained every two years and a fresh mixture of antifreeze and water added.
NOTICE:
Do not mix different types of coolant in the cooling system when adding coolant. Mixing types
can result in damage to the cooling system.
1. Be sure to adopt tap water as cooling water.
2. Be sure to add anti-rusting or anti-freeze solution to the cooling water.
3. Add anti-freezing solution to the cooling water in winter, otherwise, the frozen water may damage the cooling
water system.
Anti-rusting solution:
Be sure to use the superior quality anti-rusting solution. But do not use it in winter because it may freeze when the
air temperature is low. Its standard mixing ratio is 6%.
Anti-freezing solution:
Be sure to use the superior quality anti-freezing solution. However, it's not necessary to use it with anti-rusting
solution simultaneously. This kind of solution can be added to cooling water in all seasons. Its mixing ratio is
30%~55%, please see the chart below:
The lowest temp
-15° C
-20° C

Use the commercial available anti-freezing solution with the mixing ratio recommended by manufacturer,
meanwhile, it must be replaced every year.
CAUTION: If the mixing ratio of anti-freezing solution is too low, cooling water will freeze in low
temperature, which causes damage or rust to the water pipe. If the mixing ratio of it is too high,
the engine performance will be decreased.
Any time the cooling system has been drained for maintenance or repair, replace the coolant.
Radiator and Cooling Fan
Always check and clean the screen and radiator fins at the intervals outlined in the Periodic Maintenance Chart.
Do not obstruct or deflect air flow through the radiator by installing unauthorized accessories in front of the
radiator or behind the cooling fan. Interference with the radiator air flow can lead to overheating and consequent
engine damage.
NOTICE: Washing the vehicle with a high-pressure hose could damage the radiator fins and
impair the radiator's effectiveness. Using a high-pressure system is not recommended.
