Design Engineering Radiator Relief Cooling System Flush 16 oz – Engine Radiator Cleaner and Cooling System Flush Treatment for Improved Cooling Performance and Rust Removal

Design Engineering Radiator Relief Cooling System Flush is a powerful 16 oz treatment designed to clean and flush your engine’s cooling system, removing rust, scale, and deposits to improve radiator efficiency and overall cooling performance.

This advanced formula helps reduce engine temperatures by enhancing heat transfer, protecting against overheating during intense driving or extreme conditions, extending engine life and reliability.

Radiator Relief contains corrosion inhibitors and anti-foaming agents to protect all radiator materials—including cast iron, copper, brass, and aluminum—while balancing pH levels to prevent acidic damage and mineral buildup.

Safe for use with all types of antifreeze and coolant mixtures, this treatment works compatibly in automotive, marine, and industrial cooling systems without harming seals, hoses, or other components.

Easy to use with a recommended dosage of 1 oz per quart of coolant, Radiator Relief maintains a clean cooling system, reduces maintenance needs, and enhances engine performance by promoting efficient heat dissipation.
