What brand antifreeze does GM use?
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.
Does GM still use Dexcool?
Dex-Cool is now used in almost 40 million vehicles sold by GM since 1996. On its website, GM claims Dex-Cool will last 5 years or 150,000 miles but a steady stream of consumers insist the product is defective and has damaged their vehicles.
How long does GM antifreeze last?
No problems experienced with the cooling system and plenty of heat from the heater core. GM says that DEX-COOL is only good for five years / 150,000 miles before it must be changed out.
What color is GM antifreeze?
GM, for example, uses orange-colored Dex-Cool antifreeze, while VW’s preferred coolants are typically yellow- or blue-colored, Hemmings reports. These different types of antifreeze all do broadly the same things.
What color is GM Dexcool?
The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.
What year did GM switch to Dexcool?
1995
Back in 1995, GM began to use “Dex-Cool” coolant in its vehicles; in fact, you may very well be driving a vehicle that uses Dex-Cool.
Can you replace Dexcool with green antifreeze?
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.
What is the difference between orange antifreeze and green antifreeze?
The main difference between green and orange antifreeze is the ingredients. Green coolant uses inorganic additive technology while orange uses organic acid technology. Orange is better suited for newer cars with an aluminum block, while green is better for older cars.
Can I replace Dexcool with regular antifreeze?
Is orange coolant always Dexcool?
Can you switch from Dexcool to regular antifreeze?
Is Dex-cool orange or pink?
Dexcool is pinkish red…has been for easily a decade, if not more…
Is Dex-cool pink or orange?
the OEM dexcool is pink, yes.
Does Dexcool damage your engine?
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.
When did GM switch to Dexcool?
What happens when you mix green antifreeze with Dexcool?
The green and orange coolants do not mix. When mixed together they form a gel-like substance that stops coolant flow, and consequently, the engine overheats.
What happens if I use green coolant instead of orange?
Is it OK to mix orange and green antifreeze?
Can You Mix Orange and Green Antifreeze? It’s never a good idea to mix two different colors or types of antifreeze. Mixing two formulas won’t cause any dangerous reactions or explosions, but it could turn your coolant into a sludgy chemical mixture that won’t be able to flow properly through your cooling system.
What happens if you use green coolant instead of orange?
