## Overview

Wynn's Radiator Flush is a 325ml acid-free, dual-action cleaner designed to remove rust, scale, sludge, and oily deposits from all types of vehicle cooling systems. Compatible with all coolants including OAT, it safely cleans without damaging rubber hoses or metal parts, improving thermal efficiency and extending engine life. Perfect for both petrol and diesel engines, it ensures a thorough flush before coolant changes, supporting optimal engine temperature control and durability.

## 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: Seemed to work - Cleared a load of gunk out after use. Unsure of how effective it was, but for the price it’s worth using it every time you flush the coolant
