Do GM vehicles require Dex-cool?
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.
Why is DexCool bad?
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. The acid eats away at head gaskets and intake gaskets. Rust builds up in the system, inhibiting coolant flow, which causes overheating.
Can I use Prestone instead of Dex cool?
Yes. Prestone’s Coolant/Antifreeze is guaranteed to be compatible with all cars, vans or light trucks. Thanks to its unique and patented formula, Prestone Coolant/Antifreeze remains the only coolant on the market that can be mixed with another product within the cooling system without causing damage.
Is green antifreeze better than Dexcool?
Dex-Cool uses a combination of organic acids as its corrosion inhibitors (OAT Organic Acid Technology). GM believes that it provides better corrosion protection than regular green coolant for cooling system composed of different metals (primarily iron, aluminum, and brass), and provides a longer 5-year service life.
What can I use instead of Dex cool?
I recommend Yellow. Prestone extended life. Either 50/50 or cut it yourself with distilled. It is GM certified as a DEX Cool replacement and can be mixed with Dex Cool (don’t mix it outright, drain it, just that what does not drain out it’s ok when it intermixes).

Can you mix Prestone antifreeze with any other antifreeze?
Prestone is guaranteed for all cars and can be mixed with any other colour of coolant/antifreeze, making it the best choice for you. You can use it to top up your car or to refill the cooling system after you’ve drained and flushed it.
Can I mix antifreeze 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.
What happens if you use the wrong color antifreeze?
If you do mix different-coloured coolants they generally do not mix well and some can form a gel-like substance. This will halt coolant flow, causing blockages that can lead the engine to overheat, as well as damage to the radiator, water jackets and heater core. Also, the water pump can overheat and fail.
Is Dexcool propylene glycol?
Organic Acid Technology or OAT: Commonly referred in GM vehicles as Dex-Cool or to other manufacturers, propylene glycol. GM introduced Dex-Cool in 1995.It is made from a propylene glycol base, which makes it less poisonous than conventional IAT for children and pets.
What color antifreeze does GM use?
With respect to regular coolant, the green color is utilized to interact with rust and corrosion, letting you know visually when the coolant inside your vehicle needs to be replaced. Due to the orange color of DEX-COOL, it is harder to visually tell when the coolant must be replaced.
Is Peak orange coolant Dexcool?
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.
Can I switch from Dexcool to green coolant?
If you want to change over to the traditional coolant from Dexcool (I would, I’ve gotten to see some of the damage it’s done on fairly new vehicles) then you need to flush the system. How I’ve seen shops do this is to start the car up and let the engine run a bit to build the coolant pressure.
