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.
Use only soft (demineralized) water
in the coolant mixture. Water that
contains minerals will cut down on
the coolants 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.
Dont use a solution that contains
more than 60 % antifreeze.
This would reduce effectiveness.

CAUTION
Removing the Cooling System Cap:
Removing the cooling system cap or
drain plug 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
or drain plug. Wrap a thick cloth
around it and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When youre sure all the pressure is
gone, press down on the cap — still
using a cloth turn the cap, and
remove it.
