Hybrid organic acid technology is the third most significant category of engine coolants. The HOAT formulation combines the OAT and IAT formulas. It uses both silicates and organic acid to protect your engine and fight corrosion.
What engine coolant does BMW use?
Zerex G-48 Formula Full Strength Coolant
The ZEREX G-48 coolant is ideal for BMW cars. Designed for both diesel and gasoline engines, the coolant has low-silicate, pH, anti-phosphate technology that protects all metals, like aluminum against corrosion.
How do I know if my car needs coolant?
The high-temperature gauge is near or in the red.
One tell-tale sign of low coolant is the high-temperature gauge on the dashboard. This gauge is designed to tell you when the engine is getting too hot. Most often, the gauge should stay near the center of the H and C symbols.
Can you use water as coolant?
Technically speaking yes you can use plain water in your cooling system but it isn’t recommended as a long term solution and certainly not in extreme weather conditions. The problem with using water in your cooling system is that water freezes at 0°C.
How do I know if my coolant is Hoat?
The most obvious difference between the two is the color. HOAT is normally yellow in color, but you can also find it in purple, blue, pink or turquoise. In almost all cases, the OAT coolant is orange. In comparison, IAT coolant is often going to be green.
Valvoline’s Zerex G-05 antifreeze is a hybrid organic acid technology (HOAT) chemistry that combines the best of conventional and organic acid-based chemistry to provide protection against rust and corrosion.
Is Dex cool a Hoat coolant?
Dex-Cool® is an OAT, an ethylene glycol based antifreeze that is nitrite-, borate-, phosphate-, nitrate-, amine-, and silicate-free with the same metal wear protection as an IAT antifreeze. Dex-Cool® is trademarked by GM.HOAT (Hybrid Organic Acid Technology) Mixture of OAT and IAT antifreeze.
What color is Hoat antifreeze?
Phosphated HOAT (P-HOAT)
This coolant comes in pink or blue colour. Phosphated HOAT uses phosphates along with organic acids to prevent corrosion. This coolant is compatible with the models from carmakers like Hyundai, KIA and Honda.
What happens if you use the wrong color antifreeze?
Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket. This can lead to damage to the engine in the worst case.
Is radiator fluid the same as coolant?
And now you know that antifreeze and coolant are basically the same thing and can be generically referred to as radiator fluid. And you also know this fluid is key to keeping your vehicle engine in good working order and helps prevent it from freezing or overheating in any weather.
Is it OK to mix coolant brands?
Thankfully, the short answer is, yes, you can mix two brands of coolant. They just have to be the same type of coolant. Different coolants do different things, and mixing two different types of coolants can damage your radiator. Check the bottles to see if they are the same type.
To top up your engine’s coolant, you can simply open the reservoir cap (be careful the engine is not too hot and use a cloth wrapped around the cap to open it, as there could be some residual pressure left in the system) and add to the fluid level – what you use to do this is very important though.
Does it matter what coolant I use?
There are lots of different types of antifreeze and it’s crucial to understand that there is no single antifreeze that’s suitable for all makes and models. The best thing to do is to always use the antifreeze that’s recommended by your car manufacturer.
Does the color of coolant matter?
The truth is, color is not a reliable predictor for what type of coolant you have.
Why does BMW use blue coolant?
The blue coolant formula is a hybrid that improved the service life of coolant and is more environmentally friendly than other types of coolant. BMW replaced it on 2018+ cars with a new formula that includes silicate and has better short-term protection against corrosion.
