How to extend the life of your engine using antifreeze and coolants.

The names ‘antifreeze’ and ‘coolant’ are used interchangeably to describe the liquid in the cooling system that helps the engine run at the correct temperature. Back in the day it was more commonly referred to as anti-freeze – but nowadays you’re more likely to hear it called coolant.

Together with the right engine oil, coolant (antifreeze) is the most important liquid found within your vehicle. Without either, the engine will catastrophically fail.  But did you know that using the right product throughout the year can extend the life of your vehicle’s engine?

The main function of a coolant today is to stop the engine overheating when hot and / or freezing when the temperatures outside drop below zero.  It also protects an engine from corrosion. Many modern engines are manufactured with aluminium components which are prone to water corrosion.

What is anti-freeze?

Antifreeze is a glycol-based liquid that used to fill up your car’s cooling system. Antifreeze prevents your engine’s coolant from freezing in sub-zero temperatures.  It also helps prevent scale build up and corrosion in the engine.

What is coolant?

Coolant is the liquid that runs through an engine to keep it within its correct operating temperature range. An engine requires coolant 365 days a year. During cold weather, the coolant needs to have ‘anti-freeze’ properties in it to prevent it from freezing. A good quality coolant will already have antifreeze ingredients, so you don’t have to change the liquid inside the engine for each season. The majority of modern vehicles use liquid cooling to maintain optimum engine temperature.

Which product is right for me?

All our coolants/antifreeze products contain an organic compound called monoethylene glycol (MEG), an odourless, colourless, sweet-tasting liquid renowned for its antifreeze properties. When added to water in a car’s cooling system, ethylene glycol lowers the freezing temperature and raises the boiling point, so that the liquid circulating through the engine bay can continue operating regardless of the season or weather conditions.

When is the best time of year to buy antifreeze/coolant?

Prices fluctuate throughout the year but it is often more cost effective to buy early in the season – before it gets too cold, as a cold snap will increase demand and prices are known to increase.
