CHECKING THE COOLANT LEVEL

EWA1DX1003

WARNING

If coolant seems hot, do not remove the ra-
diator cap.

1. Stand the vehicle upright on a level surface.
2. Remove:

• Radiator cap “1”

3. Check:

• Coolant level

Maximum level “a” or below



Add coolant

up to the maximum level.

ECA1DX1004

NOTICE

• Adding water instead of coolant lowers the

antifreeze content. If, therefore, water is
used instead of coolant, check, and if nec-
essary, adjust the antifreeze concentra-
tion.

• Use only distilled water. However, if dis-

tilled water is not available, soft water may
be used.

4. Start the engine, warm this up for several

minutes, and then stop it.

5. Check:

• Coolant level

TIP

Before checking the coolant level, wait a few
minutes until the coolant has settled.

CHANGING THE COOLANT

EWA1DX1004

WARNING

If coolant seems hot, do not remove the ra-
diator cap.

1. Place a container under the engine.
2. Remove:

• Coolant drain bolt “1”

3. Remove:

• Radiator cap

Slowly loosen the radiator cap to drain cool-
ant.

TIP

When the radiator cap is loosened, coolant will
gush out transversely; therefore, bring the con-
tainer near to the outlet.
4. Thoroughly flush the cooling system with

clean tap water.
