What is antifreeze?

Antifreeze is a special liquid mixed with water and used in a vehicle’s radiator and cooling system to control engine temperature.

It has two main jobs:

1. Prevents freezing – In cold weather, it stops the water in the radiator from turning into ice and cracking the engine or radiator.

2. Prevents overheating – In hot weather, it raises the boiling point of water, helping the engine stay cool.

How Antifreeze Works

Antifreeze is mixed with water to make engine coolant.
This mixture:

• Absorbs heat from the engine

• Carries it to the radiator

• Releases the heat into the air

• Then flows back to the engine

It also protects the system from:

• Rust

• Corrosion

• Scale buildup

Common Types of Antifreeze

Most antifreeze is made from:

• Ethylene glycol (most common)

• Propylene glycol (less toxic, eco-friendly)

They come in different colors (green, red, blue, pink, orange), depending on the formula and vehicle type.

Antifreeze vs Coolant

Many people think they are the same, but:

• Antifreeze = concentrated liquid

• Coolant = antifreeze mixed with water (ready to use)

When you buy “radiator coolant,” it usually already contains antifreeze. Buy your antifreeze here: https://franean.com/collections/coolants-antifreeze
