Brake Fluid DOT 5.1
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 protec-
tion and lubrication properties.
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.
Observe the coolant manufacturer specifications for antifreeze protection, dilution and miscibility (compatibility)
with other coolants.
