NOTICE

ECA24260

• 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 concentration.

• 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

WARNING

EWA13030

A hot radiator is under pressure. Therefore,

do not remove the radiator cap when the en-

gine is hot. Scalding hot fluid and steam may

be blown out, which could cause serious in-

jury. When the engine has cooled, open the

radiator cap as follows:

Place a thick rag or a towel over the radiator

cap and slowly turn the radiator cap counter-

clockwise toward the detent to allow any re-

sidual pressure to escape. When the hissing

sound has stopped, press down on the radi-

ator cap and turn it counterclockwise to re-

move.

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

•

Coolant drain bolt “1”

•

Copper washer

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.

5. Install:

•

Copper washer

•

Coolant drain bolt

6. Pour coolant.
