Wynn's Radiator Flush - Acid-Free Dual Action Formula Removes Rust, Scale, Oil & Deposits - Compatible with All Coolants including OAT - Safe for Rubber Hoses & Metal Parts - 325ml

• ✅ DUAL ACTION FORMULA FOR DEEP CLEANING PERFORMANCE: Formulated with a powerful yet acid-free composition, this radiator flush cleaner provides an intensive dual-action effect. It effectively removes hardened scale while also eliminating rust, oil-based residues, and stubborn deposits that can accumulate over time in car & van cooling systems. This dual-function cleaning process supports the restoration of full cooling efficiency, ensuring that engines operate within safe temperature limits.
• ✅ SAFE AND COMPATIBLE WITH ALL SYSTEM COMPONENTS: Engineered for use in all closed-circuit cooling systems, the cleaner is safe for all components it contacts. It does not contain aggressive acids, making it gentle on rubber hoses, gaskets, seals, and all metal parts — including aluminium, copper, and steel. Its compatibility with all system materials ensures reliable performance without compromising the integrity or lifespan of sensitive engine parts. This safety profile is crucial for both modern and older vehicles, preventing leaks or wear due to corrosive effects.
• ✅ EXCELLENT PERFORMANCE WITH ALL COOLANT TYPES, INCLUDING OAT: This radiator flush delivers high-performance results across all types of cooling liquids, including Organic Acid Technology (OAT) coolants, which are increasingly common in modern vehicles. Its universal compatibility removes the guesswork from coolant maintenance tasks, and it seamlessly integrates into service routines regardless of the coolant type present in the system. Whether in petrol or diesel engines, this formulation proves effective at breaking down and removing accumulated contaminants, allowing the entire cooling system to function more efficiently.
• ✅ RESTORES OPTIMAL SYSTEM OPERATION AND CIRCULATION: By eliminating internal deposits, sludge, and other blockages, this flush cleaner restores the smooth operation of thermostats, pumps, and valves within the cooling system. The formulation keeps dislodged contaminants in suspension, allowing them to be drained out entirely during the flushing process. This cleaning action supports stable coolant circulation, better thermal transfer, and optimal engine temperature control. System sensors and control mechanisms benefit from the restored cleanliness, enhancing precision and reliability.
• ✅ IDEAL FOR ROUTINE MAINTENANCE AND OLDER SYSTEM CLEANING: Especially effective when used during a coolant change, this product is recommended to ensure that old residues do not mix with new coolant, which can lead to reduced efficiency or recontamination. The cleaner is particularly valuable in older cooling systems where scale, rust, and oil residues are more likely to build up. Its action allows mechanics and technicians to ensure that every coolant replacement begins with a clean foundation. Regular use of this flush as part of a maintenance schedule supports long-term engine health and prevents minor build-ups from developing into major issues

This high-performance radiator flush cleaner provides a complete internal clean of car & van cooling systems. Featuring an acid-free formulation with dual-action cleaning properties, it effectively removes scale and mineral build-up while simultaneously targeting rust, sludge, and oily deposits. Designed for use in both petrol and diesel engines, it delivers reliable results across a broad range of vehicles and engine types. Compatible with all types of coolant liquids — including the latest OAT (Organic Acid Technology) coolants — this product ensures efficient operation without the risk of material incompatibility. Its universal formulation allows for versatile application in modern and classic vehicle systems alike, without compromising rubber hoses, metal components, or seals. It is ideal for use before changing the cooling liquid, ensuring that contaminants do not linger within the system to degrade new coolant. The cleaner’s advanced formulation suspends dirt and particles during operation, enabling a complete flush when drained. This not only improves the thermal transfer capacity of the system but also helps maintain the proper function of cooling system components such as thermostats and pumps. Additionally, it contributes to smoother coolant circulation and better engine temperature control, which are critical for performance and durability. Its safe and effective cleaning action ensures long-term engine protection while minimising wear on internal components. It is particularly recommended for use in older systems where corrosion and residue may already be present, but it is equally effective as part of a regular maintenance program for newer vehicles. This radiator flush provides a clean slate for the new coolant, supporting optimal engine operation and extending the service life of the cooling system.
