Design Engineering Radiator Relief Coolant Additive Diesel Engine Coolant for Cars, Trucks, RVs, Motorcycles & More Radiator Coolant Reduces Engine Temps Up to 30°F 16 oz.

Introducing DEI Radiator Relief Coolant Additive Radiator Relief helps keep your engine cooler by lowering temperatures by up to 30°F. It’s designed to prevent overheating and protect against corrosion from electrolytic and chemical sources. This additive works with all types of coolant and antifreeze mixtures and is safe for use with any radiator material, including cast iron, copper, brass, and aluminum. It includes an anti-foaming agent and corrosion inhibitor to balance acidic effects and reduce mineral deposits. Radiator Relief enhances your radiator’s performance by improving heat transfer, which reduces engine wear during intense use. It also maintains stable pH levels to prevent core damage. ● Reduces engine temperatures by up to 30°F. ● Anti-Foaming Agent ● Corrosion Protection ● Reduces Scale Buildup ● Works with all antifreeze types. ● Recommended dosage is 1 oz per quart of coolant.
