FAQs

What is the difference between engine coolant and radiator coolant?
Engine coolant (which is also known as antifreeze) has been designed specifically to keep the radiator from freezing in extreme cold, and overheating in extreme heat.

Antifreeze is a chemical product which is often added to radiator coolants, which is why the terms are often used interchangeably. You can, however, buy radiator coolants without antifreeze.
What colour radiator coolant should I use?
The colour of radiator coolant results from dye being added to the liquid and has no bearing on the type of coolant or performance. For topping up, choose the same coolant that already is in the system. If you don’t know, it is safer to just add clean water until a full drain and refill can be done.
Is ready-to-use radiator coolant better than mixing up a concentrate?
Ready-to-use radiator coolant is convenient and has been diluted with distilled water. If using concentrate, ensure the water used for diluting is clean and ensure you correctly follow the instructions on the bottle.
What's the difference between TYPE A and TYPE B coolant?
Type A coolant contains anti-freeze (glycol) and corrosion protection. Type B coolant has anti-corrosion but no anti-freeze so is not suitable for cold weather climates.
Why are there so many radiator coolant types?
Radiator coolants have been developed to meet requirements of modern engines and environmental regulations. This includes using organic additives and long-life formulations. Premium coolants offer better protection and longer service life.
