Without radiator fluid your engine may overheat or seize up, causing extensive damage to your vehicle and possibly leaving you stranded. The corrosion inhibitors also protect the engine and its cooling system from the build-up of any scale, rust or contaminants that can degrade their operation over time.

Vehicle manufacturers take all types of weather into consideration when specifying their radiator fluid, so it’s designed to protect your vehicle in both hot and cold weather extremes. The cooling system runs in a loop, flowing through the engine and heater core before reaching the radiator and starting all over again. It acts as a means of heat transfer for the engine, warming the engine block when it’s cold and drawing heat away from components when it’s hot.

Radiator fluid is basically a mixture of chemicals that enhance anti-freezing as well as anti-overheating properties and include corrosion inhibitors. So, bring it on Mother Nature!
