In 1996, GM stopped using Dex-Cool in favor of a traditional coolant/antifreeze mixture. The decision was made due to concerns about the long-term durability of Dex-Cool, as well as its potential to cause engine damage if not properly maintained. While Dex-Cool does have its advantages, such as a longer lifespan and better heat transfer properties, it is not without its drawbacks.

It’s hard to say for sure when GM stopped using Dex-Cool in their vehicles. Some sources say it was around 2005, while others claim it was as recent as 2010. Regardless of the exact date, it’s clear that Dex-Cool is no longer the coolant of choice for GM vehicles.

There are a few reasons why GM may have switched away from Dex-Cool. For one, the coolant has been linked to engine corrosion and leaks. Additionally, it’s not compatible with all types of antifreeze, which can cause problems if you’re not careful when mixing fluids.

Finally, Dex-Cool tends to be more expensive than other coolants on the market. If you own a GM vehicle that was built before the switch away from Dex-Cool, there’s no need to panic. The coolant is still safe to use and won’t cause any damage to your car.

However, you may want to consider switching to a different type of coolant when it’s time for a change. There are plenty of great options out there that are compatible with GM vehicles and won’t break the bank.

Dex-Cool Alternative

If your car came from the factory with Dex-Cool® Coolant, you may be wondering if there’s an alternative. The good news is that there are several options available to you. Here’s a look at some of the most popular dex-cool alternatives:

1. Prestone Extended Life 50/50 Prediluted Antifreeze/Coolant This product is designed for use in vehicles that require DEX-COOL coolant. It can be used as a top up or complete flush and fill.

It provides protection against corrosion and overheating, and it’s compatible with all colors of antifreeze/coolant. 2. Zerex G05 Antifreeze/Coolant This product is designed for use in both standard and Dex-Cool cooling systems.

It contains no silicates, borates, or phosphates, so it won’t cause corrosion. It also has a low freezing point and high boiling point, making it ideal for hot weather driving. 3. Valvoline MaxLife Multi-Vehicle ATF+4 Automatic Transmission Fluid

This ATF fluid is designed for use in Dex-Cool transmissions (it can also be used in other types of transmissions). It helps to prevent leaks and slippage, while also providing smoother shifting.

Gm Dexcool

Dexcool is an antifreeze coolant designed by General Motors. It is a long-life coolant, which means it can be used for up to 5 years or 150,000 miles before it needs to be replaced. Dexcool has been used in GM vehicles since 1996 and is compatible with all types of engine materials, including aluminum.

Dexcool has several advantages over traditional antifreeze coolants. It doesn’t need to be changed as often, so it’s more convenient for drivers. It also doesn’t cause corrosion like other coolants, so it’s better for your engine.

Finally, Dexcool actually helps improve fuel economy by keeping the engine cooler. If you have a GM vehicle from 1996 or later, chances are it came with Dexcool already in the radiator. But if you’re adding coolant to your car or doing a flush and fill of the system, you can use Dexcool without any problems.

Dex-Cool Problems

If your car uses Dex-Cool antifreeze, you may want to keep an eye out for potential problems. Some reports have surfaced of Dex-Cool causing engine damage, particularly with Chevrolet engines. The most common complaint is of a milky substance appearing in the coolant overflow tank.

This can be indicative of oil mixing with the coolant, and if left unchecked can lead to engine failure. If you notice this happening in your own vehicle, it’s important to take it to a mechanic as soon as possible so they can diagnose and fix the problem before it causes any serious damage.

Dex Cool Antifreeze 50/50

Most carmakers recommend Dex-Cool, which is also called HOAT (hybrid organic acid technology) antifreeze. It uses silicates and phosphates instead of the traditional corrosion inhibitors, such as borates and nitrites. Dex-Cool can last five years or 150,000 miles before it needs to be replaced.

What Color is Dex-Cool Antifreeze

If you’re looking for information on Dex-Cool antifreeze, you’ve come to the right place. In this blog post, we’ll provide detailed information on what color Dex-Cool antifreeze is, as well as some other important facts about this type of coolant. Dex-Cool antifreeze is a long-life coolant that is used in many GM vehicles.

It is orange in color and has a silicate-free formula that helps prevent corrosion. Dex-Cool also contains additives that help protect against leaks and deposits.

When Did Gm Stop Using Dex Cool


Do All Gm Cars Use Dexcool?

No, not all GM cars use Dexcool. In fact, most GM cars use traditional coolant, also known as green coolant. Dexcool is an extended-life coolant that was introduced in the 1990s and is now used in many newer GM vehicles.

When Did Chevy Stop Using Dexcool?

In 2004, GM began to transition away from using Dex-Cool antifreeze in its vehicles. By 2006, Dex-Cool was no longer being used in any new GM vehicles. There are a few reasons why GM made this change.

First, there were reports of coolant leaks in someGM vehicles that were caused by corrosion of the engine parts. This was thought to be due to a chemical reaction between the coolant and the materials used in the engine. Second, there were also reports of coolant system failures resulting in engine overheating.

These failures were more likely to occur in hot weather conditions or after the vehicle had been driven for a long period of time without cooling down. Finally, customers simply didn’t like the fact that they had to regularly add coolant to their vehicles (Dex-Cool needs to be replaced every 3 years or 36,000 miles). They felt it was an unnecessary hassle and expense.

GM decided that it wasn’t worth continuing to use Dex-Cool given all of these issues. So, they switched to a different type of coolant which is compatible with all types of engines (including those made by other manufacturers).

Does Dexcool Damage Your Engine?

If you have ever had a car with an engine that uses Dexcool coolant, then you know how important it is to maintain the correct level of this fluid in your system. But what happens if Dexcool runs low or completely runs out? Can this type of coolant really damage your engine?

The answer is yes. If Dexcool runs low or completely runs out, it can cause serious engine damage. This is because Dexcool contains corrosion inhibitors that protect your engine from rust and corrosion.

When these inhibitors are depleted, rust and corrosion can start to form on engine parts, eventually leading to engine failure. So, if you use Dexcool in your car, make sure to keep an eye on the level of coolant and top it off when necessary. It could save you a lot of money and hassle in the long run!

What Gm Cars Use Dexcool?

If you own a GM car, then it likely uses Dexcool coolant. Dexcool is an antifreeze/coolant that is specifically designed for use in GM vehicles. It is a long-life coolant that can last up to 5 years or 150,000 miles before it needs to be replaced.

Dexcool has many benefits over traditional coolants, including improved heat transfer and corrosion protection.

When GM Switched to DEX-cool #shorts


In July of 2004, GM stopped using Dex-Cool as the factory fill coolant for all vehicles. This was due to lawsuits and customer complaints alleging that the coolant caused corrosion in engines.
