What is Dex-Cool coolant?

ACDelco DEX-COOL® is an ethylene glycol based fluid that provides maintenance-free protection against freezing and boiling but also against corrosion. Extended coolant life, often for the whole life of the engine or vehicle, is obtained through the use of virtually non-depleting corrosion inhibitors.

  • Dex-Cool is a specially formulated GM coolant which will not mix with traditional coolants, and was used in various GM applications up through the 2004 model year. The green and orange coolants do not mix.

Is Dex-cool the same as antifreeze?

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.

What kind of coolant is Dexcool?

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.

Can you add regular coolant to Dex-cool?

Do not mix Dex-Cool with regular anti-freeze! Dex-Cool is a specially formulated GM coolant which will not mix with traditional coolants, and was used in various GM applications up through the 2004 model year.

Is Dex-Cool coolant bad?

In the 1990s, GM introduced an engine coolant called Dexcool. It’s supposed to last 5 years or 150,000 miles, but there have been problems with this coolant. Cooling systems that use Dexcool exhibit more acid buildup and rust in the system when the coolant level gets low and oxygen is allowed to enter the system.

What color is universal antifreeze?

Traditional North American “ green ” antifreeze, the original “universal” formula that everybody used until the introduction of today’s extended-life coolants.

What happens if I put a different coolant in my car?

Using the wrong coolant or mixing different types together can hinder the car’s performance. It may also increase corrosion in the radiator. Using the wrong coolant can lead to corrosion and other damages to the radiator, water pump, radiator hoses, cylinder gasket, and more.

Can I use Prestone Dex cool?

Can I use peak coolant instead of Dex cool?

Peak Dexcool Concentrate Orange Antifreeze is made for use in GM cars and trucks requiring a Dex-Cool antifreeze. It is an orange colored ethylene glycol based antifreeze compatible for use in all automobiles, light duty trucks and motorcycles.

What years did GM use Dexcool?

Now there is a new engine coolant formulated to last five years/100,000 miles – that’s three years/70,000 miles longer than conventional coolants. Dex-Cool, which is made by Texaco, is being used exclusively by General Motors in some buildout 1995 models and all 1996 cars and trucks except Saturn and Geo.

Can I mix yellow and red coolant?

You can mix two different colors of the same kind of coolant without any problem whatsoever.

Can I mix different coolant brands?

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.

Is Dex Cool still used?

Dex-Cool is now used in almost 40 million vehicles sold by GM since 1996. On its website, the company now also warns owners to consult their vehicle “owner’s manual for the type of coolant right for your vehicle” and never “mix one type of coolant with the other.”

Does Dex Cool eat gaskets?

if your using Dex Cool antifreeze, its eating away at your engines gaskets and cooling system components. it could also get inside your engine and mix with your oil from gaskets or alumiunm parts being eatin away from the dex cool.

What color is Dex cool?

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.

The Difference Between DEX-COOL Coolant & Regular Coolant

Images courtesy of Jupiterimages/Comstock/Getty Images DEX-COOL is a unique form of antifreeze that can be found in certain types of coolants and was developed via the use of organic acid technology. According to the manufacturers and General Motors, DEX-COOL can help you get more mileage out of your car while also improving its performance. The DEX-COOL cooling system, despite this, has been connected to manifold gasket failures in some General Motors engines.

Composition

When compared to other coolants, DEX-COOL is distinguished by the fact that it is composed of many distinct components. Antifreeze that is used on a regular basis is made out of water combined with methanol and ethylene glycol. In order to keep your automobile from overheating, these items are blended and poured into your engine. Higher boiling points are achieved by using these goods. DEX-COOL, as well as other organic acid antifreezes, do not contain glycol as a primary component. DEX-COOL, on the other hand, is made up of a variety of various phosphates and silicates, as well as the organic acid technology itself.

Color

To distinguish DEX-COOL coolant from other types of coolant, the makers frequently create the coolant in a different hue from the other types. DEX-COOL is often orange or red in color, whereas regular coolant is typically green. When it comes to ordinary coolant, the green hue is used to interact with rust and corrosion, allowing you to visually determine when the coolant within your car needs to be changed. In part, this is due to DEX-orange COOL’s tint, which makes it more difficult to visually determine when the coolant should be replenished.

Engine Materials

Additionally, DEX-COOL is specially formulated to interact with aluminum engines, as seen by the differences in composition and color between the two coolants. Using DEX-COOL for an aluminum engine will aid to reduce corrosion, assuming that the car’s previous owner did not use typical green coolant in the vehicle. In contrast to typical green coolant, which is meant to change color as a result of corrosion, corrosion that occurs in aluminum engines does not cause the coolant to change color.

Mixing

The structural differences between DEX-COOL and ordinary coolant make it imperative that the two types of coolants are not mixed in the same vehicle’s cooling system. Sludge can build as a result of mixing, which can lead to engine failure in some cases. To swap between the two coolants, you will need to wait until the original coolant has been properly drained through the engine before doing so. Although this is true, flushing DEX-COOL does not always effectively eliminate the specific silicates that are present.

Dex-cool Contamination

The coolant in your cooling system is perhaps one of the most crucial components. In addition, it must be clean, non-corrosive, and non-conductive, as well as having freezing and boiling qualities that are adequate for the environment. The coolant should be changed every two years, according to industry standards. Some automobiles are being built with so-called “extended-life” coolants, which are designed to last longer than standard coolants. Dex-cool is one of the most popular extended life coolants on the market.

  1. These prolonged service intervals have proven to be nothing but a source of frustration for the consumer in the past.
  2. It appears that Dex-cool interacts with plastic sealing surfaces, resulting in leakage at the intake manifold gaskets, according to mounting evidence.
  3. This will not violate your warranty and will save you money in the long run.
  4. EVEN MORE SO IF IT’S DEX-COOL!
  5. DEX-COOL DOES NOT LAST FOR FIVE YEARS OR ONE MILLION MILES*.
  6. In order to prevent corrosion from occurring due to the absence of silicates (which are normally present in green antifreeze), a new corrosion inhibitor method was implemented.
  7. Unfortunately, the dex-cool has the potential to cause a fairly terrible failure.

If the residue is contained within the radiator, hoses, or recovery bottle, cleaning and removing the particles should be quite simple.

Certain instances have been reported where the orange mud solidifies and seems to expand or force the gasketed surfaces out of position, resulting in leaks.

As a result, they claim, the cooling systems enable evaporation, causing the Dex-cool to become destabilized, weaken, and lose its already inadequate protection, resulting in the muddiness of the water.

Neither of these hypotheses provides a comprehensive explanation of the situation, and these are not commonly accepted viewpoints.

They don’t have any.

They aren’t, in fact.

While the car is still under warranty, it is best to ignore the problem.

I believe it is this attitude that has resulted in the present class action lawsuit being brought against the company.

ethylene glycol is used in the production of 95 percent of all of these coolants, which are then blended with 50 percent water before being placed in a car or truck.

The variations in coolant brands are due to the use of compounds that improve the corrosion prevention qualities of the coolant.

More information about silicates may be found here.

OAT-formulated coolants provide “background” or reserve protection (similar to a vitamin), and as a result, they tend to respond more slowly to changes in the environment, as opposed to silicate-formulated coolants, which react more quickly to changes in the environment (works like an aspirin).

These chemicals may differ depending on the type of coolant being used.

The OAT-formulated coolant used in European automobiles has a small amount of low-level silicates added to it to give even more and faster protection.

More information about coolants, inhibitors, and silicates may be found in this section.

In other words, you should be taking care of your maintenance-free cooling equipment.

There are several inhibitors available. There are a lot of automobiles on the road. In only a few autos does corrosive gel build up in their cooling system, which causes overheating and leakage. The gel is thick, gooey, sticky, gritty, and muddy in appearance.
