7.3.3 Refilling Coolant
NOTE!
Do not let coolant drip or leak out while refilling. Do not let coolant leak out onto the ground
or into bodies of water otherwise this will cause damage to the environment.
IMPORTANT!
Engine damage caused by excessive temperature difference!
When refilling with cold coolant in an engine at operating temperature there is a risk of en
gine damage caused by excessive temperature difference.
For this reason:
S Do not fill with cold coolant.
Fill the cooling system of the engine with a mixture of tap water and ethylene glycol antifreeze agent or an
ticorrosion agent.
Only use approved fluids and lubricants (see “Fluids and Lubricants ..." publication).
1. Remove cap (1).
2. Slowly fill in coolant up to the lower edge of the
filler neck.
Ensure that the ratio of “water to antifreeze” is cor
rect.
3. Reinstall cap (1).
4. Let engine run for a short period and then
recheck coolant level.
