Compatible with all coolant types including OAT, it enhances thermal efficiency and protects critical engine components, making it essential for both routine maintenance and restoring older systems to peak condition. ## Description 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. Review: Does the job - Good quality Review: Does what it says - Seems decent enough. Put the whole lot into a 4.9l capacity Corsa and ran for 30mins with the heaters on full blast three times to ensure a deep and thorough clean. Ran 16litres of water through the rad after and then three more ten minute sessions to rinse through the block. Still slightly soapy and I'll give it one more "hot" rinse before refilling the rad with a little over 2l concentrated antifreeze. Hope I'm doing this right as never done before! ## Features - Causes serious eye irritation. - car parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000Y8WF0Q | | Best Sellers Rank | 4,334 in Automotive ( See Top 100 in Automotive ) 61 in Antifreeze & Coolants | | Brand | Wynn's | | Customer Reviews | 4.5 4.5 out of 5 stars (338) | | Date First Available | 1 Nov. 2007 | | Guaranteed software updates until | unknown | | Item Weight | 330 g | | Item model number | WY56064 | | Manufacturer | Wynn Oil UK | | Manufacturer part number | WY56064 | | Model | WY56064 | | Product Dimensions | 2.36 x 3.94 x 9.37 cm; 330 g | | Voltage | 12 Volts | ## Images ![Wynn's Radiator Flush - Compatible with All Coolants Including OAT - 325ml - Image 1](https://m.media-amazon.com/images/I/717GM8LPnyL.jpg) ![Wynn's Radiator Flush - Compatible with All Coolants Including OAT - 325ml - Image 2](https://m.media-amazon.com/images/I/71Y4wMogEPL.jpg) ![Wynn's Radiator Flush - Compatible with All Coolants Including OAT - 325ml - Image 3](https://m.media-amazon.com/images/I/21cLxlbIbcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does the job *by M***I on 1 August 2025* Good quality ### ⭐⭐⭐⭐⭐ Does what it says *by A***R on 13 April 2020* Seems decent enough.
