What is Dex Cool on Impala

Dex Cool is a type of antifreeze that was used in many General Motors vehicles from 1996 to 2008. It is an ethylene glycol based coolant specifically designed for use with aluminum radiators and internal engine components. Dex Cool provides corrosion protection, has a higher boiling point than traditional antifreeze, and contains silicates which act as lubricants for water pump seals and other gaskets.

The Impala uses this specific type of antifreeze to ensure optimal performance and prevent overheating or freezing in the engine bay.

The Impala is an iconic car, and its engine uses a special type of coolant known as Dex Cool. This coolant is designed to provide superior cooling performance while also lasting longer than traditional antifreeze. Dex Cool has been tested to last up to five years or 150,000 miles in the Impala’s engine, making it a great choice for those looking for long-lasting protection from corrosion and overheating.

It also helps keep the car running at optimal temperatures regardless of environmental conditions.

What Does Dex-Cool Do for a Car?

Dex-Cool is a type of coolant designed to work with the newer cooling systems found in modern cars. It helps keep your engine running efficiently and effectively by controlling the temperature of the system. Dex-Cool has been specifically formulated to help reduce corrosion and excessive wear on metal parts, maximizing their lifespan.

It also increases the boiling point of coolant which prevents overheating as well as reduces deposits that can form on many surfaces around an engine such as cylinder walls, valves, spark plugs, and other components. Additionally, it helps protect rubber seals from deteriorating due to extreme heat or cold temperatures. The main benefit of using Dex-Cool for a car is its ability to improve fuel efficiency by reducing drag caused by higher operating temperatures within the motor compartment.

All these features make Dex-Cool one of the best choices available when selecting a coolant for your vehicle’s cooling system!

Do I Put Antifreeze in Dex-Cool?

No, antifreeze is not necessary for Dex-cool. Dex-cool is a type of long life coolant or antifreeze designed to last up to five years or 150,000 miles without needing replacement. It does not require the addition of any additional chemicals such as antifreeze, and in fact adding more than 10% of other types of coolants can reduce its effectiveness.

This means that you should never mix Dex-Cool with regular green anti freeze, as this could cause damage to your engine and cooling system. Additionally, if you are topping off your vehicle’s coolant level it is important to use only pre-mixed 50/50 Dex-Cool solution from a jug labeled as “Dex Cool Ready To Use”. If you do find yourself running low on coolant then make sure that the product used states clearly on the label “For GM Vehicles Using DEX COOL Antifreeze” so there can be no mistake about what type of product must be used in your car’s cooling system.

What Happens When Dex-Cool is Low?

When Dex-cool is low, it can cause a variety of issues for the cooling system in your car. Low levels of this antifreeze solution can cause corrosion and rust to form on metal parts such as the radiator or water pump. This corrosion can reduce their efficiency and lead to premature failure.

Additionally, if there’s not enough Dex-cool in the engine, then it won’t be able to provide adequate protection against freezing temperatures during winter months. Finally, having too little fluid also reduces circulation within the engine block which will result in overheating and potentially damaging other components such as pistons or seals.

What Kind of Coolant Does a Chevy Impala Take?

The coolant that a Chevy Impala takes is usually an ethylene glycol-based type of antifreeze, which acts as both an anti-freeze and a heat transfer medium. Many manufacturers recommend using either Dexcool or Prestone brand coolants in their vehicles. As with any car, it’s important to check your owner’s manual for specific recommendations about the type of coolant you should use in your vehicle.

It’s also important to be sure that the cooling system has been flushed and filled according to manufacturer specifications before adding new coolant to ensure proper engine temperatures are maintained. Additionally, when changing out the old fluid for new one, it is essential not only to use the appropriate type but also get all air bubbles out of the system so there won’t be any overheating issues later on down the road.

What Color is Dex-Cool Antifreeze

Dex-Cool antifreeze is an orange-colored coolant that is primarily used in General Motors vehicles. This type of antifreeze contains ethylene glycol as its base and also includes other additives to provide additional protection against corrosion and cavitation erosion. Dex-Cool must be mixed with water before it can be used, but it should not be mixed with any other types of antifreezes.


This blog post has provided an overview of Dex Cool on Impala. It is clear from this article that Dex Cool is a type of antifreeze specifically designed for use in General Motors vehicles, including the Impala model. Additionally, it helps to protect against corrosion and maintains performance levels while keeping the engine temperature at optimal levels.

By using Dex Cool antifreeze in your Impala, you can help ensure that your engine runs smoothly and efficiently for years to come.
