Most people think of antifreeze or coolant as green. For years many antifreeze/coolants were green in color but now many coolants come in a variety of colors. Antifreeze or coolant can be yellow, pink or red, blue, and green.Mar 17, 2015
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.
Variations of coolant/antifreeze can come in; pink, red, orange, blue, green, and yellow. This can make it confusing when trying to decide which coolant you need in your vehicle. The different colors can mean different properties of the liquid.
But what about different colored coolants? The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple.
If it looks colorless, looks rusty, or has things floating around in it, flush your cooling system and add new coolant.
|HOAT (Hybrid OAT)||Silicates & Organic Acids||YELLOW|
|HOAT (Hybrid OAT, Phosphate-free)||NAP Free||TURQUOISE|
|P-HOAT (Phosphated HOAT)||Phosphates & Organic Acids||PINK / BLUE|
|Si-OAT (Silicated HOAT)||Silicates & Organic Acids||PURPLE|
While the manufacturers of these coolants recommend only using them in an aluminum radiator, as opposed to the copper/brass radiators, we still don’t recommend them in our all-aluminum radiators. … We recommend the traditional yellow/green coolant because it has always worked for us.
There is green antifreeze and orange antifreeze. … These days you can actually get yellow antifreeze, blue antifreeze, pink antifreeze and more. The fact is, mixing these liquids is not safe.
It’s perfectly backwards compatible if you want to do that. But you really don’t want to mix them, it’s not that good of an idea to mix them. If you want to have the correct coolant added for you, consider YourMechanic. They will be able to come to your home or office to perform this service.
Yes it does, I have a new Ford Escape and the coolant was pink colored from the Ford dealer.
Green antifreeze is made with special tweaks to the formula specifically to help prevent the corrosion of metals in a vehicle’s cooling system. That older formula is typically meant for vehicles made before the year 2000, which were built with more steel and copper components than modern vehicles.
The transmission’s cooler is located in the coolest radiator well after the coolant has flowed through the cooling fins. When a leak forms in this cooler, the two liquids mix, resulting in foamy pink transmission fluid. The engine’s coolant now has transmission fluid mixed in.
You can mix two different colors of the same kind of coolant without any problem whatsoever. But if you mix a significant amount of one type in with the other type, you’re weakening your corrosion inhibitors (it happened to my brother, and look at the condition he’s in now).
And you do need at least a 70/30 antifreeze/water mix for the best results. Typically, Valvoline says, coolant comes in green. … These different types of antifreeze all do broadly the same things. They prevent water from freezing and boiling off and inhibit corrosion and mineral deposits in the radiator.
Blue G11 coolant doesn’t mix with G12 or green, orange or any other off the shelf coolants.
To make sure you’re choosing the right HOAT coolant, look at the brand name, rather than the liquid’s color. The HOAT formulation is a combination of the OAT formulation and the IAT formulation. HOAT uses both silicates and organic acid to protect your engine and combat corrosion.
One of the new types is “organic acid technology,” or OAT. It’s orange. … Instead of OAT, most new cars now use a “hybrid” antifreeze that’s formulated with both OAT and the silicate inhibitors from green (Japanese hybrids have different inhibitors). It comes in too many colors to pretend this type is color-coded.
(Pink) Antifreeze + Coolant. Our specially designed formula for Audi ® 1997-2007, Volkswagen ® 1997-2008, Porsche ® 1999-2009, and Jaguar ® 1999 and newer. This technology regulates your engine’s temperature, prevents freezing and protects the engine from corrosion.
DO NOT MIX pink and red, they ARE NOT COMPATIBLE! You have an 02 4Runner, yours takes red, mix it with 50% water. Pink is a completely different coolant to the red, its not just premixed red.
While green coolant is often thought of as traditional or conventional and the color orange is associated with the newer long-life products, there are no hard-and-fast color rules when it comes to engine coolants. All will help keep the cooling system from both overheating and freezing.
The key to maximizing the life of an aluminum radiator is not so much the coolant brand as it is the water type. All coolants sold today will protect the aluminum radiators adequately however distilled water must be part of the package.
Antifreeze mixes with water to form a covalent bond to prevent the water from freezing. … Antifreeze Blue is a full concentrate which meets BS6580 and contains the same pure ethylene glycol and anti-corrosive additives as the Red. Its application is for protection for up to a maximum of 2 years.
Green engine coolants are designed for use in older cars (think pre-2000), ones that contain a lot of steel and copper components in the cooling system. To protect these metallic parts from rust and corrosion, Inorganic Additive Technology (IAT) gets added to the mix.
Is red and orange antifreeze the same? … There is no difference between red and green antifreeze. It is ORANGE antifreeze that used to be a concern. It is now safe to mix the colors.
Prime Orange antifreeze+coolant is designed to work with these specific vehicles: All GM ® vehicles 1995 & newer/GM approved (GMC, Chevrolet, Buick, Cadillac, Pontiac, Saturn, Oldsmobile, Hummer), most Ford ® vehicles 2011 – 2018 (Ford, Lincoln, Mercury) and most Chrysler ® vehicles 2013 & newer (Ram, Dodge, Jeep, …
Premium Member. Dexcool is pinkish red…has been for easily a decade, if not more…
Green coolant turning a orange or reddish brown color, would suggest rust in the system from either the radiator or the engine(BTW if there is a presence of silver/copper haze in the Coolant, that would suggest the possible use of a stop-leak).
If you are low on fluid or have a leak, a general rule of thumb is, green IAT is always replaced by green IAT coolant. Dex-Cool or an OAT product with equivalent specifications is always necessary to replace orange or yellow organic-based antifreeze. … The proper coolant and mixture ratio is important.
