The key difference between red and green antifreeze is that red antifreeze lasts longer than green antifreeze. An antifreeze contains ethylene glycol and propylene glycol as the bases. When an antifreeze is used along with water, it can serve as a coolant.Apr 12, 2018
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.
Green coolant is your conventional coolant (Ethylene Glycol base) and is the most common type of coolant found. Red coolant is typically has a base of Organic Acid Technology which has a different chemical makeup of green coolant and is designed to be suitable for aluminium radiators.
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. … Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant.
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.
If you have a red coolant in your cooling system, you have an Extended Life Coolant. This coolant is recommended for use in Toyota, Scion, and Lexus. It can be used in any engine requiring an OAT engine coolant. Red coolant offers 150k miles of protection.
As a quick guide, if your topping up the coolant levels, use the same color as is in the vehicle already. However just because it’s the same color doesn’t necessarily mean it’s the same type. … For example, Toyota has green and red, but it depends on the year and model of the vehicle as to which kind is needed.
Some people believe that they can mix the two. This is a mistake and can lead to expensive repairs. The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating.
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.
VW, Audi, and Porsche are OAT users, too, but most others have resisted. 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.
|Transmission Fluid||Pink, red, or brown|
|Power Steering Fluid||Reddish brown|
|Brake Fluid||Pale amber|
|Coolant/Antifreeze||Bright green or yellow|
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.
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). … A milky color indicates the presence of oil in the system. This is not good; it usually means that a head gasket, intake manifold, or transmission oil cooler is leaking oil or transmission fluid into the engine coolant.
Prestone is yellow, but many other coolant manufacturers use different colours. “These days, there’s no real reason for a coolant manufacturer to use a certain colour, so it’s not easy for you to know what chemicals are in the coolant just by seeing whether it’s blue, green, yellow or orange.Jun 1, 2020

Cars made after 1998 normally need antifreeze that uses silicate-free, organic acid technology (OAT). These types of antifreeze offer better corrosion protection so that parts don’t need to be changed as often. Cars made before 1998 usually need antifreeze that isn’t OAT-based and that does contain silicate.
There are standard anti-freezes that are red and cars that have Dexcool® will be labeled as such. Another myth is that Dexcool® is not glycol based. … Both ethylene glycol (EG) and propylene glycol (PG) are used as the antifreeze base. From here the additional additives and inhibitors are added.
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.
No! You should never mix coolant fluid with regular tap water. Tap water contains minerals that can form deposits inside the radiator and cooling system passages of your engine. … This and the proper mixture of coolant and distilled water will help your car and its cooling system run without breaking for a long time.
aircap, Ks. 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 ® Conventional Green antifreeze+coolant is the original coolant. This low silicate formula, when used as directed, will provide protection for a minimum of 1 year. Prime ® will guard against temperature extremes and the effects of rust, corrosion and premature water pump failure.
Can you mix red and orange antifreeze? 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.
If you mix two different coolants together, it will create a think substance that resembles that of a jelly. If this happens, the coolant will not be able to do its intended job. Instead, it will cause the engine to overheat. The damage can reach gasket, water pump, and radiator.
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.

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).
Dex-Cool uses a combination of organic acids as its corrosion inhibitors (OAT – Organic Acid Technology). GM believes that it provides better corrosion protection than regular green coolant for cooling system composed of different metals (primarily iron, aluminum, and brass), and provides a longer 5-year service life.
There are two fluids used by your vehicle that are red. These are the automatic transmission fluid and the power steering. Both of these are hydraulic fluids. You’ll want to check your owner’s manual to see if your vehicle, like some others, actually uses automatic transmission fluid in the power steering system.
There are several signs of a leaky heater core: First you may notice a sweet smell from your vents. … Coolant/antifreeze leaking out through the heater core means that the overall coolant level in the system will be low and the engine is in danger of overheating – which is the most common cause of mechanical breakdown.
If you’ve noticed an odd, sweet smell coming from your car after you shut the engine off you might have an antifreeze leak. … It’s part of your vehicle’s cooling system, which controls the engine’s temperature so that it runs properly and doesn’t overheat.
