Coolelf Cartech -37°C is a "very-long-life" premium glycol-based engine coolant containing cutting-edge phosphate inhibitor technology backed by a robust organic backbone (P-OAT - Phosphated Organic Additive Technology). The high temperature stability combined with flux passivation properties makes this coolant an excellent and future proof choice for today’s and tomorrow’s engine cooling systems.

Coolelf Cartech -37°C provides year-round frost and excellent corrosion, freeze and boil protection in light vehicles and heavy-duty applications.

Coolelf Cartech -37°C is exempt from potentially harmful additives such as nitrites, borates and amines, leading to a safer environment. Coolelf Cartech -37°C is also free of silicates, which excludes any possible issues caused by instable silicate gel or silicate dropout.

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

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

Suitable for use in combustion engines in passenger car and heavy-duty applications.

Coolelf Cartech -37°C may be used with confidence in engines manufactured from cast iron, aluminium or combinations of the two metals, and in cooling systems made of aluminium or copper alloys.

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 Cartech -37°C give the coolant:

• Chemical neutrality (pH 7.5 – 8.5)

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

• Resistance to foaming

• Excellent hard water stability with a unique matrix of hard water stabilisers & sequestrants.

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

Maintenance free coolant with depletion-free and stable inhibitors.

Carefully selected additives to reduce environmental impact.
