Excellent protection against corrosion, erosion, and cavitation, for aluminium water pumps.

Heat transfer remains optimised: fully organic additives allow avoiding any formation of deposits and leave surfaces clean.

The additives in COOLELF AUTO SUPRA -37°C give to the coolant:

Chemical neutrality (pH 7-8.5).

A reserve of alkalinity to neutralise the acids resulting from the combustion gases.

Resistance to foaming (mainly instability of the foam that might form).

Compatibility with hard water (maximum 40°F).

No silicates, phosphates, chromates, nitrites or boron contains.

COOLELF AUTO SUPRA -37°C is inert to elastomeric seals and paints.
