Maximum frost protection is ensured with an antifreeze concentration equal to 55% of the volume,
as frost protection and heat transfer properties deteriorate beyond this point. A higher concentra‐
tion also leads to higher operating temperatures for the drive engine.
1.
NOTICE!
The engine can be damaged if the antifreeze concentration is insufficient!
Corrosion.
Damage to the cooling system.
Engine housing fracture.
➤ Check the coolant.
➤ Ensure frost protection for the coolant.
➤ Replenish immediately if necessary.
2. To test the coolant, use the coolant tester as instructed by the manufacturer.
If the proportion of antifreeze is too low: Change the coolant.
Closing tasks:
1. Close the filler cap.
2. Shut the enclosure.
10.3.1.3 Mixing the coolant
The coolant is a mixture of clean, fresh water with special additives (corrosion protection/antifreeze
additives).
To protect against corrosion and raise the boiling point, the coolant must remain in the cooling sys‐
tem throughout the year.
Never use water without added coolant. Water alone is corrosive at drive engine operating temper‐
ature. Water alone does not offer sufficient protection from boiling or freezing of the coolant.
An adhesive label with the recommended mixture ratio for the coolant is fitted by the coolant ex‐
pansion tank, see Figure 29.
