Design Engineering DEI 041204 Radiator Relief Engine Coolant Additive

The Design Engineering DEI 041204 Radiator Relief is a high-performance engine coolant additive engineered to optimize your cooling system's efficiency. This advanced formula reduces coolant surface tension to maximize thermal conductivity, helping to lower operating temperatures by up to 30°F during extreme use conditions.

Key Features:

• Reduces engine operating temperatures up to 30°F by enhancing heat transfer efficiency
• Corrosion inhibitor protects against mineral deposits and scale build-up
• Stabilizes pH levels to prevent electrolysis and reduce rust formation
• Anti-foaming agent promotes superior coolant contact in cylinder heads
• Compatible with all antifreeze types and coolant mixtures
• Helps extend cooling system component life and reduce engine wear

Radiator Relief works by improving the thermal transfer process throughout your entire cooling system. The balanced formulation counters the acidic effects that naturally develop in antifreeze and water solutions over time, while preventing the pH fluctuations that can lead to core damage. The anti-foaming technology accelerates heat dissipation from critical engine components, making this additive ideal for high-performance applications, towing, racing, and extreme climate conditions.
