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 up to 30°F reducing engine wear that occurs during extreme use. Radiator Relief™ is also formulated with a corrosion inhibitor that reduces mineral deposits. This is the first additive that maintains pH levels that otherwise fluctuate over time resulting in core damage.
