The coolant used in GM vehicles has been Dex-Cool since 1996. In recent years, there have been reports of engine damage caused by Dex-Cool. As a result, some people are wondering when GM stopped using Dex-Cool.
The answer is that GM is still using Dex-Cool, but they have changed the formulation to try to address the problems that have been reported.
The coolant in your car is important to its overall health and performance. So, when did GM stop using Dex Cool?
Dex-Cool was an antifreeze used by General Motors (GM) in their vehicles.
It was introduced in the mid-1990s as a replacement for conventional ethylene glycol based coolants. Dex-Cool was touted as being more environmentally friendly and providing better cooling properties than traditional coolants.
However, Dex-Cool has been linked to engine overheating and corrosion issues.
In some cases, it has even caused engines to fail completely. As a result, GM stopped using Dex-Cool in their vehicles in 2006.
If you have a GM vehicle that was manufactured between 1995 and 2006, it is important to be aware of the potential problems that can occur with Dex-Cool.
If your car starts to overheat or experience other cooling system issues, it is best to take it to a mechanic for diagnosis and repair.
Dex-Cool Alternative
If you own a GM car or truck built after 1995, it probably uses Dex-Cool coolant. Dex-Cool is an OEM (original equipment manufacturer) coolant designed by General Motors. It’s a long-life coolant that was originally developed for use in GM’s aluminum engines, but it can be used in any engine.
Although Dex-Cool has been used successfully by millions of GM customers over the years, there have been some reports of problems with it. In particular, some people have reported that their cars develop leaks in the cooling system after using Dex-Cool. There have also been reports of engines overheating and/or burning up because of using Dex-Cool.
If you’re concerned about these reports and don’t want to use Dex-Cool in your car, there are several alternatives available. You can use any standard automotive antifreeze/coolant in your car as long as it meets the requirements for your specific engine. Just be sure to follow the maintenance schedule for changing your coolant – typically every 30,000 miles or so – regardless of what type of coolant you use.
Some people swear by using only distilled water in their cooling systems, although this isn’t recommended by most experts since it doesn’t contain any anti-corrosion additives. You can buy pre-mixed 50/50 coolant at most auto parts stores, or you can mix your own 50/50 solution of distilled water and antifreeze/coolant. Be sure to use a quality antifreeze/coolant such as Prestone or Zerex; stay away from generic brands as they may not provide adequate protection for your engine.
Does Gm Still Use Dex-Cool?
Yes, GM still uses Dex-cool in many of its vehicles. Dex-cool is a type of coolant that is designed to last longer than traditional coolants. It can typically last for up to five years or 150,000 miles before it needs to be replaced.
However, some GM vehicles may require Dex-cool to be replaced more frequently due to certain engine conditions.
When Did Gm Go to Dex-Cool?
In 1996, GM switched to using Dex-cool antifreeze in all of its vehicles. Dex-cool is a trademarked name for a type of coolant/antifreeze that uses an organic acid technology. It is made by General Motors and was first used in their cars in 1995.
Many carmakers have since adopted it for use in their own vehicles. Dex-cool has been linked to engine corrosion and failure in some GM cars, leading to a class action lawsuit being filed against the company in 2004. In 2010, GM extended its warranty on vehicles with Dex-cool to 8 years or 100,000 miles (160,000 km), whichever came first.
As of 2016, there have been no recent reports of engine problems associated with Dex-cool.
What Gm Cars Use Dex-Cool?
GM Dex-Cool is a coolant used in some GM vehicles. It is a propylene glycol based coolant, and is designed to last for the lifetime of the vehicle. Dex-Cool has been known to cause problems with leaks and clogging, and it is recommended that it be replaced every 5 years or so.
Can You Replace Dexcool With Regular Antifreeze?
Yes, you can replace Dexcool with regular antifreeze, but there are a few things to keep in mind. First, Dexcool is designed to last longer than regular antifreeze, so if you do switch, you’ll need to change your coolant more often. Second, regular antifreeze isn’t as effective at protecting against corrosion, so your engine may be more vulnerable to rust and other damage.
Finally, Dexcool is specifically formulated for use in GM vehicles, so switching to another type of coolant could void your warranty.

Conclusion
In the mid-1990s, General Motors began using a new type of coolant in its vehicles called Dex-Cool. This coolant was supposed to be more effective and longer lasting than the traditional green antifreeze. However, GM has since stopped using Dex-Cool due to numerous reports of problems with it.
These problems include engine overheating, gasket and radiator failure, and corrosion. GM has issued several recalls over the years for vehicles affected by these issues. If you own a GM vehicle that uses Dex-Cool, it is important to be aware of these potential problems and have your vehicle regularly serviced to avoid them.
