Shell Coolant Longlife Concentrate
Shell Coolant Longlife Concentrate is a high-performance organic additive technology (OAT) antifreeze and coolant concentrate designed to provide extended service protection for modern automotive and industrial engines. Formulated to meet a wide range of international standards and OEM requirements, it delivers advanced corrosion protection, reliable freeze resistance and long-term cooling system stability when diluted as recommended.
A key performance advantage of Shell Coolant Longlife Concentrate is its extended service capability. The OAT formulation provides durable corrosion protection for cooling system components made from aluminium, cast iron, steel, copper and other common engine materials. With a pH of 8.3 and reserve alkalinity of 7.5, it helps maintain chemical stability and protect against acid formation over prolonged operating intervals.
When mixed at a 50% concentration with water, Shell Coolant Longlife Concentrate provides freeze protection down to –37°C. This ensures dependable protection against freezing damage in cold climates while also contributing to effective heat transfer and engine temperature control during operation.
The product meets a broad range of industry and OEM requirements, including ASTM D3306, D4985 and D6210, BS 6580, SAE J1034, AFNOR NFR 15-601, JIS K2234 and NC 956-16. It also meets multiple manufacturer specifications such as MB-Approval 325.3, MAN 324 Typ SNF, VW TL-774 D and TL-774 F, Cummins CES 14603 and 14439, Deutz DQC CB-14, Fiat 9.55523, Ford WSS-M97B44-D, Renault 41-01-001/-S Type D, Jaguar-Land Rover STJLR 651.5003, DAF 74002 and Wärtsilä DLP799861.
Typical physical characteristics include a density of 1,123 kg/m³ at 20°C, water content of 2.6% by weight and a distinctive pink colour for product identification. These controlled properties support consistent mixing performance and reliable cooling system operation.
Shell Coolant Longlife Concentrate must be diluted with clean water before use, following equipment manufacturer recommendations for concentration and service intervals.
