Does it matter what color your antifreeze is?

Does it matter what color your antifreeze is?

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.

What is GM’s orange Coloured antifreeze called?

Dex-Cool
One of the new types is “organic acid technology,” or OAT. It’s orange. General Motors pioneered this chemistry starting with 1996 models in the U.S. and using the name Dex-Cool.

What is green antifreeze used for?

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.

What happens if you use green coolant instead of orange?

Can I mix green coolant with orange coolant? This is one of those questions usually asked after the fact, and usually engine damage has already occurred. The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow, and consequently, the engine overheats.

What antifreeze does GM use?

For a couple decades now, GM has used a type of coolant known as Dex-Cool. Despite not being called antifreeze, it still accomplishes the same task, so you don’t have to worry about replacing Dex-Cool for the winter months or anything like that.

Does GM still use Dexcool?

Dex-Cool is now used in almost 40 million vehicles sold by GM since 1996. On its website, GM claims Dex-Cool will last 5 years or 150,000 miles but a steady stream of consumers insist the product is defective and has damaged their vehicles.

What is pink antifreeze used for?

They are meant to reduce corrosion which causes them to last longer. Pink Antifreeze: Pink antifreeze is specifically targeted at a handful of Japanese automakers and their vehicles. Toyota, Scion, and Lexus are all specified as the vehicles you should be using with something like an extended life pink antifreeze.

Can I switch from orange to green antifreeze?

What is orange antifreeze used for?

Both orange and green antifreeze serve as engine coolants, designed to keep it from freezing or overheating. They also defend the cooling system against corrosion.

Are there different colors of antifreeze and coolant?

You might be thinking, “What color is antifreeze? What color is Dex-Cool®?” It’s true, coolant liquid comes in different colors, most commonly green (orange for Dex-Cool®). Each color is a unique formula that should not be mixed.

What’s the problem with GM’s Orange antifreeze?

Many GM-manufactured vehicles use an orange anti-freeze known as Dex-Cool, however many consumers have reported problems with the use of this antifreeze in their vehicles. Problems revolve mainly around the overheating of the coolant system, resulting in damage to the gasket, radiator, engine and transmission.

What kind of coolant does GM OE DEX-COOL use?

PRODUCT DETAILS ACDelco GM OE Dex-Cool Antifreeze Extended Life Coolant Concentrate is an orange, silicate and phosphate free, premium-grade coolant/antifreeze that is formulated with a chemical composition that minimizes breakdown of metal components in contact with the fluid.

What happens when you put green and orange coolant together?

The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow and consequently the engine overheats. There are some coolants that claim compatibility with Dexcool, but I would rather err conservatively and add what the system is supposed to take rather than gamble.
