Is Dex-cool better than green antifreeze?

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 happens if I put green antifreeze instead of Dex-cool?

When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating. As the coolant stops flowing, other problems can occur as well such as happens with radiators, water jackets, and even heater cores. The water pump may overheat and stop working.

What color antifreeze does a 2007 Chevy Impala take?

The manufacturer of the 2007 Chevy impala recommends using organic acid technology orange extended life antifreeze.

Can you mix Dex-cool with green antifreeze?

Dex-Cool has been formulated to be orange in order to help visually distinguish it from traditional green colored coolant. Mixing green coolant will reduce the effectiveness of Dex-Cool from 5 years/150,000 miles down to only 2 years/30,000 miles.

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.

Can I use Prestone instead of Dex cool?

What coolant should I use for Impala?

You’ll want to use A50/50 mix. The best thing to buy here is going to be Prestone DEX-COOL, part #AF860, which is sanctioned by GM, pre-diluted so You don’t have to mess with finding distilled water, and runs about $17 for a gallon at Autozone.

What is Dex-Cool on a 2006 Impala?

The type of antifreeze the 2006 Chevy Impala uses is dex-cool extended life 50/50. You will come into many problems with an engine. There could be excessive oil use, requiring the oil to be replaced sooner than expected.

What years did GM use Dexcool?

Dex-Cool, which is made by Texaco, is being used exclusively by General Motors in some buildout 1995 models and all 1996 cars and trucks except Saturn and Geo. GM postponed using Dex-Cool in Saturn cars until the 1997 model year because it did not have enough data to make use of the new coolant possible in 1996 models.

What happens if you use the wrong color antifreeze?

What Happens if You Use the Wrong Coolant? It’s important to note that the type of coolant you should use can’t accurately be identified by color. Using the wrong coolant can lead to corrosion and other damages to the radiator, water pump, radiator hoses, cylinder gasket, and more.

Is there a substitute for DexCool?

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).

How can you tell the difference between DEX-COOL and regular antifreeze?

The main way to tell the difference between Dex-Cool and regular antifreeze is that Dex-Cool is typically orange, whereas antifreeze is usually green. Are there advantages to Dex-Cool? Why did Chevy and GM make the change over to Dex-Cool?

Does GM use antifreeze or coolant?

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.

What are the problems with GM Dexcool engine coolant?

In the 1990s, GM introduced an engine coolant called Dexcool. It’s supposed to last 5 years or 150,000 miles, but there have been problems with this coolant. 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.

What is the difference between a regular antifreeze and a coolant?

DEX-COOL varies from other coolants in that it is made up of different materials. Regular antifreeze is composed of water mixed with methanol and ethylene glycol.
