What is engine coolant? Coolant (once in a while alluded to as liquid catalyst or radiator liquid) is utilized to manage your motor temperature and keep it from overheating. Is simply mixing Dexcool and universal antifreeze together safe?
Is mixing Dexcool with green antifreeze possible? Of course, it is and it is done when there are few to no other options. The green and orange coolants don’t blend. At the point when combined, they structure a gel-like substance that stops the coolant stream, and thus, the motor overheats. This is one of those inquiries typically posed sometime later, and as a rule, the motor most likely has been damaged.
There are a few universal types of antifreeze that guarantee similarity with Dexcool, however, I would prefer to blunder moderately and include what the framework should take as opposed to bet. To prepare for significant motor disappointment, read on.
What Exactly Is Dexcool?
During the 1990s, GM presented a motor coolant called Dexcool. It should most recent 5 years or 150,000 miles, yet there have been issues with this coolant. Cooling frameworks utilizing Dexcool display corrosion when the coolant level gets low and oxygen is allowed to enter the framework.
The corrosive destroys head gaskets and admission gaskets. Rust develops in the framework, repressing the coolant stream, which causes overheating.
Generally speaking, credit various cooling framework issues to the utilization of this questionable item, despite the fact GM stands firm in its confidence in the product. There were class activity suits against GM on this issue, and GM agreed with certain proprietors starting in 2008.
Is Universal Coolant Compatible With Dexcool?
Try not to blend Dex-Cool with standard liquid catalyst! Dex-Cool is an exceptionally refined GM coolant that won’t blend in with universal antifreeze and was utilized in different GM applications up through the 2004 model year.
A blend of exchange synthetic substances will void the GM support, will corrupt coolant uprightness, and perhaps harm the coolant arrangement of your GM vehicle. Dex-Cool is orange so it is in no way mistaken for conventional green shaded coolant. Blending green coolant will decrease the adequacy of Dex-Cool from 5 years/150,000 miles down to just 2 years/30,000 miles.
Buy DexCool to finish off your universal antifreeze. Privately owned businesses sell Dex-Cool including Shell and Prestone. Assess a coolant meets GM’s Dex-Cool GM6277M specs, which ought to be marked on the side of the bottle.
You can get the proper coolant at a car parts supply store. If all else fails, request that a store representative assist you with finding the right coolant.
Utilize a coolant exchanger to supplant your Dex-Cool coolant. GM suggests coolant exchangers as the correct strategy to trade the old Dex-Cool antifreeze in your vehicle with universal antifreeze. Most car fix shops will have the option to deal with this administration for you, and handle the removal of the old coolant.
Can I Use Universal Coolant Instead Of Dexcool?
Yes. But make sure when you take your vehicle to a shop, have the universal antifreeze depleted completely on the off chance that you have blended in different coolants. Non-DexCool coolants will cause Dex-Cool to gel and become muck, which will prompt an assortment of motor issues.
GM prescribes any vehicle mixing Dexcool with green antifreeze be flushed more than once to guarantee all debased coolant has been completely removed.
The universal antifreeze synthetically responds and structures as a gel as opposed to a fluid. The universal antifreeze quits coursing through the framework, stops up coolant paths and water coats, radiators, and warmer centers.
The water siphon overheats and bombs because of an absence of ointment in the coolant. Head gaskets blow, heads twist, and the motor endures significant harm.
If I have Dexcool in my vehicle, can you mix Dexcool and universal antifreeze safely? Yes, temporarily.
GM recommends antifreeze flushing Dexcool at 150,000 miles.
Basic Tips for Radiator Maintenance
Here’s the primary concern with regards to cooling maintenance. Regardless of whether you are running Dexcool (the orange stuff) or ethylene glycol (the green stuff), examine the coolant level and the condition of the coolant during each oil change or have your trusted mechanic make it a normal part of the inspection.
Furthermore, top off your radiator at regular intervals or 25,000 miles whichever comes first (annually is highly recommended unless your car runs warm). These activities will mitigate issues related to mixing Dexcool and universal antifreeze.
What Happens If You Don’t Flush Coolant?
Possible engine damage if you don’t flush your radiator soon enough. The shade of sound motor coolant is green (for ethylene glycol) or orange (for Dexcool). A corroded shading demonstrates that the rust inhibitor in the coolant has separated and it can no longer control rust and scale development. Cleaned and flush the radiator with a crisp 50/50 blend of coolant to maintain proper operation.
A smooth shading shows the nearness of oil in the framework. This isn’t acceptable; it, as a rule, implies that a head gasket, consumption complex, or transmission oil cooler is spilling oil or transmission liquid into the motor coolant. This is a fatal blend that will execute a motor or transmission quite promptly.
Thick Coolant Is An Indication Of Good Coolant
The motor coolant should feel thick to the touch and smooth (like motor oil). If it feels coarse, the coolant is grimy and ought to be flushed and supplanted with a new 50/50 blend.
On the off chance that the coolant doesn’t feel like this it has lost its viscosity (the greasing up and rust hindering operators have crumbled) and the framework is in danger for rust and scale development, just as water siphon wear.

Check The Smell Of Your Antifreeze
Change the antifreeze on the off chance that it smells consumed. Additionally, change the inside regulator. It’s gone bad since if the car is overheating. Overheating harms the bi-metallic spring that opens and shuts the indoor regulator valve.
Above all, discover what made the framework overheat and fix it to maintain a strategic distance from significant motor harm.
So is mixing Dexcool and universal antifreeze together a good idea?
Ideally no, in a pinch, yes.
But sometimes people have to make due. In an emergency, you rarely or never have an ideal solution. An emergency kit sitting in your truck is always a good idea and it is well worth the inconvenience of months or years of hassle for the one single moment when it is your only option.
Dex Cool is a great option for your car. If your car already uses Dex Cool the best option will be to continue to use only Dex Cool and not mix other types of antifreeze. This is a regular part of proactive car maintenance that will save you money, time, and headache in the long run.
