When it comes to your vehicle’s cooling system, two terms are often used interchangeably: antifreeze and coolant. While they are very closely related, there are important distinctions between the two.
A coolant is a substance, typically liquid, that is used to reduce or regulate the temperature of a system. An ideal coolant has high thermal capacity, low viscosity, and low cost, is non-toxic and chemically inert, and neither causes nor promotes corrosion of the cooling system.
Not sure which color coolant you need? Use Prestone's antifreeze color chart to find the best antifreeze for your vehicle and driving conditions.
The new coolant you are adding must be the same type and color as the existing antifreeze in your car’s cooling system. Failure to adhere to this rule could cause costly damage to your engine.
Coolant is as vital as oil for your car, preventing overheating and freezing. Learn about coolant types, when to change them, and how to avoid costly mistakes.
