FAQs How often does my car need a new coolant? Just keep in mind that each colour has a unique formula and function. On the contrary, an OAT coolant in an old-style radiator will damage the radiator and wouldn’t even protect against radiator corrosion. For instance, an OAT coolant works wonders for new cars but using it in an older radiator that has lead solder is never going to work out. Important things to remember about coolant colours in carsĪs a rule of thumb, if your car came with a particular coolant colour, don’t try to change it needlessly. Here are a few tips on keeping your car’s radiator cool. Just be sure you follow the percentages mentioned on the bottle sensibly. These things increase the deposits and scale in the radiator, thus reducing the cooling efficiency. Therefore, to be on the safe side, create the mix with distilled water. Moreover, tap water contains calcium, magnesium, and hardness ions. Tap water always contains chlorides that can be corrosive. It is advisable to use distilled water to reduce the corrosion levels even if modern coolants can work with tap water. To make it work, you will have to mix water and the coolant at a ratio of 50-50, unless specified otherwise or already premixed. How to prepare coolant Coolant fluid has to be mixed with water to achieve the necessary thermal rangeĮngine coolant comes in a concentrated formula and requires to be mixed. It is recommended to flush out or change the green coolant fluid after every two years or 10,000 kilometres. The green coloured coolant is usually used in older cars that were manufactured before the mid 90’s such as GM, Ford and Chrysler. Green coloured coolants are very popular and make up for excellent corrosion protection. Green coolant: An IAT (Inorganic Additive Technology) formula coolant is bright green in colour. The OAT coolant is popularly used in makes including Toyota, VW, GM, Honda, Nissan and Mitsubishi. Read the owner’s manual before using this coolant in an older model just to be sure. Both the colours are found in the OAT formula. If you’re wondering the difference between red and orange coolants– the answer is simple. OAT coolants are recommended to be flushed out of the cooling system at an interval of 10 years or after every 22,000 kilometres. With the help of special additives, the coolant system is prevented from rust and corrosion, but metal parts might need some servicing over time. There are no phosphates or silicates in the OAT formula, in fact, the formula contains corrosion inhibitors offering improved protection of the coolant systems and a long-lasting one. Red and orange coolants: An OAT (Organic Acid Technology) formula liquid coolant comes in different colours including orange, blue, dark green, red and bright red. Let us go through the difference between red, orange and green coolants in detail. Difference between red, orange and green coolant Different coolant colours in cars have different properties Using the wrong coloured coolant will damage your car’s performance and end up deteriorating the radiator and engine. This colour difference isn’t there to make your coolant look fancy or pretty, but it has a very important purpose. You might notice a new coolant colour in the reservoir of your new car different from the coolant colour in the reservoir of your last car. In the UAE, coolants come in red, orange and green colours. Difference between coolant colours in cars When choosing the right coolant, you need to understand the difference between each colour and how that affects your car’s performance. Moreover, coolants also prevent car metal parts from rusting and ensure that the rubber or plastic vehicle parts don’t corrode. Car coolants absorb the heat from the engine and prevent engine water from boiling. Engine coolant is a fluid that keeps a vehicle’s radiator from overheating in extremely hot weather conditions.
