Radiator Relief™


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.

  • 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

With the latest heat wave here in the mid west, my temp gauge would fluctuate quite a bit. radiator relief helped reduce the temps to hold more steady.

My 74 Z28 on hot summer days (96ºF) idle temps would climb to 210ºF. After adding Radiator Relief™ it will stay at 180ºF while idling. Great Product! Highly recommended!
