They could be a blend of IAT and OAT chemicals, and were therefore named ‘Hybrids’. 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. “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 for coolant/antifreeze, there are a couple of key differences as to why some products are one colour and others are another, as our expert Bruce Ellis explains below: 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. Why is Coolant/Antifreeze Different Colours?
The colour of engine coolant isn’t there to make it look pretty. 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.
