Coolant
Guideline
– Only use high-grade, silicate-free coolant with corrosion inhibitor additive for aluminum motors. Low grade and unsuitable antifreeze
causes corrosion, deposits and frothing.
– Do not use pure water as only coolant is able to meet the requirements needed in terms of corrosion protection and lubrication proper-
ties.
– Only use coolant that complies with the requirements stated (see specifications on the container) and that has the relevant properties.
Antifreeze protection to at least −25 °C (−13 °F)
The mixture ratio must be adjusted to the necessary antifreeze protection. Use distilled water if the coolant needs to be diluted.
The use of premixed coolant is recommended.
