Shell Coolant Longlife Plus Ready to Use
Shell Coolant Longlife Plus Ready to Use is a premium silicated organic additive technology (Si-OAT) antifreeze and coolant supplied pre-diluted for immediate use. Designed to meet the latest OEM requirements, it combines the long-life performance of organic acid technology with the fast-acting protection of silicate additives, providing advanced corrosion protection particularly for modern aluminium-intensive engine designs.
A key benefit of Shell Coolant Longlife Plus Ready to Use is its extended corrosion protection capability. The balanced Si-OAT formulation protects cooling system components manufactured from aluminium, cast iron, steel, copper and other common engine materials. With a minimum pH of 7.5, it helps maintain chemical stability within the cooling circuit and protects against corrosion and scaling over extended service intervals.
The product provides freeze protection down to –37°C, ensuring reliable defence against freezing damage in cold operating environments. Being pre-diluted, it eliminates the need for on-site mixing and reduces the risk of incorrect dilution ratios, ensuring consistent protection and heat transfer performance throughout the cooling system.
Shell Coolant Longlife Plus Ready to Use meets a comprehensive range of international standards and OEM requirements, including ASTM D3306, D4985 and D6210, BS 6580, Cummins CES 14603, MB-Approval 325.5/325.6, MAN 324 Typ Si-OAT, VW TL-774 G, AFNOR NFR 15-601, JIS K2234, NC 956-16 and SAE J1034. These approvals confirm its suitability for a wide range of modern European and international vehicle applications.
Typical physical characteristics include a density of 1,075 kg/m³ at 20°C and a pink appearance for clear product identification. These controlled properties support consistent performance and compatibility within approved cooling systems.
Shell Coolant Longlife Plus Ready to Use should be used as supplied and must not be further diluted.
