Nulon Green Premium Long Life Coolant Concentrate is a green, hybrid additive technology (HAT), Type A coolant suitable for use in most vehicles that require green conventional ethylene glycol based coolants. Nulon Green Long Life provides excellent anti-freeze, anti-boil and enhanced corrosion protection over standard glycol coolants thanks to the hybrid additive technology that blends OAT and IAT coolants. The added inhibitor package remains more stable than traditional coolants, helping to extend service life up to 7 years or 500 000 km, whichever comes first. Nulon Green Long Life is safe to use with all types of materials including rubber, plastics and gasket material and wont become abrasive, helping to prevent seal leaks. Nulon Green Long Life Coolant is concentrated, designed for mixing with soft or demineralised water from 33% up to 50% by volume, this will provide the best performance and temperature protection from -37C up to 128C* At 50% Mix. This coolant can be used in all cooling systems where aluminium, brass or copper radiators are installed including older vehicles where corrosion inhibitors are recommended. The mixing of coolant types and brands is not preferred practice. For top ups, ensure you select the same type/brand of coolant that your vehicle is currently using or select a coolant that is designed to be mixed. If you are performing a complete service or refill, ensure the system is thoroughly cleaned of existing coolant by using a radiator flush. A radiator flush will help remove built up sludge, scale and corrosion while also neutralising any existing coolant left behind, preparing the cooling system for a fresh, clean refill. To find the correct coolant suggested for your vehicle; either add your vehicle to My Garage or check with your manufacturer, vehicle user manual, your local mechanic or head in-store and talk to one of our friendly team.
