Changing Coolant

Change coolant according to Scheduled 
Maintenance (page 8-3).

For mixture percentage:

To change coolant

1. Remove the cooling system cap.

2. Only when the engine is cool, loosen 

the radiator drain plug and drain the 
coolant into a suitable container. 
Properly dispose of the used coolant.

3. With the drain plug loose but not fully 

removed, flush out the system with 
running water.

Radiator coolant will damage paint.
Rinse it off quickly if spilled.

•

Use only soft (demineralized) water 
in the coolant mixture. Water that 
contains minerals will cut down on 
the coolant

’

s effectiveness.

•

Don

’

t add only water. Always add a 

proper coolant mixture.

•

The engine has aluminum parts and 
must be protected by an ethylene-
glycol-based coolant to prevent 
corrosion and freezing.

•

DO NOT USE alcohol or methanol 
antifreeze. DO NOT MIX alcohol 
or methanol with the coolant. This 
could damage the cooling system.

•

Don

’

t use a solution that contains 

more than 60 % antifreeze.
This would reduce effectiveness.

CAUTION

CAUTION

Removing the Cooling System Cap:
Removing the cooling system cap 
while the engine is running or hot is 
dangerous. This might lead to cooling 
system and engine damage and could 
result in serious injury from escaping 
hot coolant or steam. Turn off the 
engine and wait until it

’

s cool. Even 

then, be very careful when removing 
the cap. Wrap a thick cloth around 
the cap and slowly turn it 
counterclockwise to the first stop.
Step back while the pressure escapes. 
When you

’

re sure all the pressure is 

gone, press down on the cap 

—

 still 

using a cloth 

—

 turn the cap, and 

remove it.
