Buying Guide

What is Coolant Additive?

A coolant additive is a chemical agent added to automotive antifreeze/coolant in order to increase its performance. The most common additive is ethylene glycol, which acts as an antifreeze and helps protect against corrosion. Other additives include propylene glycol (which also prevents freezing and boiling), sodium chloride (which inhibits corrosion), and phosphate (which prevents scale build-up).

Who Needs Coolant Additive?

You may need a coolant additive if your car is leaking antifreeze, if your car is overheating, or if your check engine light is on. A coolant additive can also help prevent corrosion and build-up in your cooling system.

How Does Coolant Additive Work?

Coolant additive is designed to protect your engine from corrosion and overheating. It does this by creating a barrier between the metal surfaces of your engine and the coolant, which prevents the coolant from coming into direct contact with the metal. This barrier also helps to prevent rust and other forms of corrosion from forming on the metal surfaces.
