Coolelf Neotech -37°C is a "very-long-life" premium engine coolant based on monoethylene glycol and Organic Additive Technology (OAT) that provides year-round frost and excellent corrosion, freeze and boil protection. The coolant can withstand high temperatures thanks to the increased oxidation stability and compensates the negative effects of potential flux contamination.

Coolelf Neotech -37°C is designed to cope with the most extreme engine conditions in both passenger cars and heavy-duty applications.

Coolelf Neotech -37°C contains no 2-EHA, nitrite and borate. It is also compliant with EU CO2 emission performance standards.

Coolelf Neotech -37°C ensures long-lasting protection thanks to the OAT backbone with virtually non-depleting organic corrosion inhibitors, until -37°C.

Coolelf Neotech -37°C is ready for use, as a mix with demineralised water.

Suitable for use in combustion engines and Battery Electric Vehicles in automotive and heavy-duty applications if there is no requirement on electrical conductivity.

Coolelf Neotech -37°C can be used for cooling systems made of iron, steel, aluminium as well as copper alloy.

Recommended coolant change interval*:

• 500 000 km/4 years when used in trucks

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

*It is recommended to refer to the vehicle’s maintenance manual.

Organic technology ensures a long-term action to offer maximum protection against

any type of corrosion, erosion and cavitation, even at high temperatures.

The organic additives in Coolelf Neotech -37°C give the coolant:

• Chemical neutrality (pH7.9- 9.0)

• A reserve of alkalinity to neutralize the acids resulting from the combustion gases

• Resistance to foaming

• Excellent hard water stability avoiding the formation of insoluble deposits

Prevents the formation of gels or deposits in the cooling system.

Carefully selected additives to reduce environmental impact.
