Every car manufacturer, including Mercedes-Benz has developed its own coolant or requires a discernible coolant that is unique to explicit years and models. There are many colors of coolants to aid distinguish each including yellow, red, purple blue, green, and orange.
Different vehicles require different coolants. There are varieties for every type of vehicle, from diesel engines to American, Asian and European vehicles. Each one is specifically formulated to keep its designated engine type running in extreme temperatures.
What kind of coolant do you put in a Mercedes ml350?
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.
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.
What happens if you mix OAT and Hoat?
Mixing IAT with OAT, HOAT or NOAT antifreezes will not damage your vehicle’s cooling system; however the mixture will negate the long life/extended life attributes of these formulations.
What brand of antifreeze is Hoat?
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.
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.
Is Prestone coolant Hoat or OAT?
Prestone is an OAT coolant/antifreeze but also contains anti-corrosion ingredients to protect your cooling system. It can be used in all cars effectively, offering the same levels of protection, and without any damage.
Can you mix universal coolant with Hoat coolant?
The answer to that is Yes. You can mix Peak with Zerek or Prestone – but only as long as the coolant is the same chemical type. The ratio doesn’t matter as much, but the type & application should match. The easiest way to remember is that you should try and match type – IAG with IAG, OAG with OAG and HOAT with HOAT.
Does it matter what color coolant I use?
The truth is, color is not a reliable predictor for what type of coolant you have.
Are Hoat and OAT coolants compatible?
Hybrid organic acid technology (HOAT) is not compatible with OAT or NOAT coolants.
What do coolant colors mean?
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
What happens if you put wrong coolant in your car?
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.
It’s never a good idea to mix two different colors or types of antifreeze. Mixing two formulas won’t cause any dangerous reactions or explosions, but it could turn your coolant into a sludgy chemical mixture that won’t be able to flow properly through your cooling system.
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.
