Description:

COOLELF AUTO SUPRA -37°C is a «very long life» coolant based on monoethylene glycol and organic inhibitors of corrosion.

COOLELF AUTO SUPRA -37°C is a cooling liquid that can be used in all cooling systems of combustion engines in cars, vans, trucks, buses, constructing machines and agricultural tractors.

In accordance with French Decree No. 95-326 of 20th March 1995 concerning the distribution of certain substances containing monoethylene glycol, COOLELF AUTO SUPRA -37°C contains an additive to give it a bitter taste as a guarantee against accidental ingestion by children or users.

Applications:

• COOLELF AUTO SUPRA -37°C is a permanent coolant that can be used during the whole year.
• COOLELF AUTO SUPRA -37°C is ready for use, as a mix with demineralised water.
• COOLELF AUTO SUPRA -37°C can be used for cast iron as well as aluminium engines, and also in engine radiators in aluminium or copper alloy.
• Recommended oil change interval:

• 650,000 km/8000 hours/5 years when used in trucks

• 250,000 km/5 years when used in cars.

All antifreezes and coolants based upon monoethylene glycol are regarded as special industrial wastes and must be disposed of in approved centres for environmental reasons.

Advantages:

• 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).

• COOLELF AUTO SUPRA -37°C contains no silicates, phosphates, chromates, nitrites or boron.
• COOLELF AUTO SUPRA -37°C is inert to elastomeric seals and paints.
