Engine Coolant, HI-COOL, also known as antifreeze, is diluted automobile coolant to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it’s important to know what variety is right for your car or truck.
Since Coolant technology has evolved so much in the last few decades, you need a formula with a special additive to allow chemistries old and new to work together. Multi-vehicle Antifreeze/Coolant helps extend the life of higher mileage vehicles with special additives to keep radiator working properly without rusting.
