Design Engineering DEI 40200 Radiator Relief Coolant Additive 16 oz

Design Engineering's Radiator Relief is a high-performance coolant additive designed to enhance the efficiency and protection of all water-cooled engines. This 16-ounce bottle treats cooling systems by improving heat transfer, reducing operating temperatures, and protecting against corrosion and cavitation.

Key Features:

• Reduces coolant temperatures by improving heat transfer efficiency
• Compatible with all types of antifreeze and coolant formulations
• Provides protection against rust, corrosion, and electrolysis
• Helps prevent water pump cavitation and seal degradation
• Safe for use in automotive, marine, RV, and powersports applications
• Easy to use—simply add to existing coolant system
• 16-ounce bottle treats most standard cooling systems

Radiator Relief works by reducing the surface tension of coolant, allowing it to make better contact with metal surfaces for improved heat dissipation. This helps maintain optimal engine temperatures, especially in high-performance or demanding conditions. Ideal for street vehicles, race cars, motorcycles, boats, and any water-cooled engine where thermal management is critical.
