These ‘Extended Life Coolants’ (ELC), were usually orange in colour and offered a five-year or 100,000-mile change interval. “Next came Organic Acid Technology (OAT) coolants, whose chemical make-up offered better protection for cooling systems, and extended the life of the coolant. With these types of coolants, you’d normally have to change them every two years, or every 60,000 miles. “Older coolants that used Inorganic Additive Technology (IAT) were usually blue or green in colour.
As our expert, Bruce Ellis, explains: “In days gone by, the colour of coolant was determined by the type of chemicals used to prevent corrosion - meaning you could tell a lot about the type of coolant used by its colour. As such, great care should be taken when topping up your car’s cooling system. Unfortunately, it’s no longer possible to determine a specific type of coolant from its colour alone, as the shade has little bearing on the chemical make-up of the product. Vehicle fluids vary in colour from bright pink to reddish-brown, so if you ever need help identifying which is which, take a look at our car fluid finder chart.Īs for coolant/antifreeze, there are a couple of key differences as to why some products are one colour and others are another. Why is Coolant/Antifreeze Different Colours? Which Coolant/Antifreeze Should I Use in My Car?.What Do Coolant/Antifreeze Colours Mean?.Why is Coolant/Antifreeze Different Colours?.
We also look at some of the advantages of using high-performance coolant/antifreeze, so you can make a more informed decision on the product that’s right for you. However, it’s important to make sure you’re putting the right fluid in your car, so here we’ll give you some insight into the differences. There are historical reasons why it comes in different colours, but these days it doesn’t necessarily tell you all that much. The colour of engine coolant isn’t there to make it look pretty. If so, you might be wondering which you should use if you need to top up? Have you ever wondered how pink, orange, blue and green engine coolants differ from each other? Perhaps you’ve bought a car, checked the coolant/antifreeze reservoir for the first time and noticed it’s different from your last car.
