Radiator Relief supercharges your radiator by transferring heat more efficiently through the radiator. This proven coolant additive will reduce your operating temperature up to 30 degrees and cut engine warm up time in half. The majority of engine wear occurs at the extremes- extreme heat and extreme cold start ups. Radiator Relief can help reduce this wear and extend engine life by minimizing those extremes.

  • 30 degrees lower operating temperature
  • 50% quicker warm up
  • No mixing required; drain a quart - add a quart
  • Compatible with water and all anti-freeze mixtures
  • Safe with all alloys
  • 100% Biodegradable, Non-Corrosive and Non-Toxic
  • For use in all water cooled engines

  • Radiator Relief solves the problem of high engine temps by reducing coolant temperatures up to 30 degrees. Radiator Relief is an excellent method of treating cooling systems as a preventive step to help avoid overheating, electrolytic (electrolysis) and chemical corrosion and is compatible with all coolant additives and anti-freeze mixtures. Both an anti-foaming agent and corrosion inhibitor which balances the negative acidic effects that can develop over time are also included. Radiator Relief is also safe to use with all types of radiator materials including cast iron, copper, brass and aluminum. Radiator Relief supercharges your radiator by transferring heat more efficiently through the radiator. Similar to the original formula this proven coolant additive will reduce your operating temperature reducing engine wear that occurs during extreme use. Radiator Relief is also formulated to reduces mineral deposits. This is the first additive that maintains pH levels that otherwise fluctuate over time resulting in core damage. Reduces engine temps up to 30F Includes anti-foaming agent Corrosion inhibitor Reduces pre-existing scale build-up Compatible with all types of anti-freeze Recommended 1 oz per quart of coolant
  • Clear Radiator Relief - 32 oz.

    Since 1995, DEI has been a pioneer in the automotive performance industry. Wrapping the exhaust system or headers on a vehicle with DEI's exhaust wrap will reduce under-hood temperatures up to 70% while improving performance and protecting components from extreme power-robbing heat.
