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
