Level Up Your Chevy Equinox’s Cooling System: The Ultimate Coolant Guide

Maintaining your Chevy vehicle‘s cooling system is essential for its optimal performance and longevity. A crucial aspect of this maintenance is selecting the right coolant, as it plays a vital role in regulating engine temperature and preventing overheating. In this comprehensive guide, we will delve into the intricacies of coolant selection for Chevy vehicles, addressing the question: “What coolant does Chevy use?”

Understanding Coolant Types:

Coolants, also known as antifreeze, come in various types, each with distinct properties and applications. The two primary types are Inorganic Additive Technology (IAT) and Organic Acid Technology (OAT).

• IAT Coolant: IAT coolants, commonly referred to as conventional coolants, contain inorganic additives such as silicates and phosphates. These additives provide corrosion protection by forming a protective layer on metal surfaces within the cooling system. However, IAT coolants have a shorter lifespan and require more frequent replacement, typically every two years or 30,000 miles.

• OAT Coolant: OAT coolants, also known as extended-life coolants, utilize organic acids as additives. These additives offer superior corrosion protection and a longer lifespan compared to IAT coolants. OAT coolants typically last five years or 100,000 miles, making them a more cost-effective option in the long run.

Which Coolant Does Chevy Use?

Chevy vehicles generally recommend the use of OAT coolants, specifically those meeting the Dex-Cool specification. Dex-Cool is a brand name for a specific type of OAT coolant developed by General Motors (GM), the parent company of Chevy. Dex-Cool coolants are formulated to provide long-lasting protection against corrosion, cavitation, and scale formation within the cooling system.

Benefits of Using Dex-Cool Coolant:

Using Dex-Cool coolant in your Chevy vehicle offers several benefits, including:

• Extended Lifespan: Dex-Cool coolants have a longer lifespan compared to conventional IAT coolants, typically lasting five years or 100,000 miles. This reduces the frequency of coolant changes, saving time and money in the long run.

• Superior Corrosion Protection: Dex-Cool coolants contain organic acids that provide superior corrosion protection for metal components within the cooling system, including aluminum and iron. This helps prevent rust and premature component failure.

• Prevents Cavitation and Scale Formation: Dex-Cool coolants contain additives that help prevent cavitation (the formation of vapor bubbles) and scale buildup within the cooling system. This ensures efficient heat transfer and protects against localized overheating.

How to Choose the Right Coolant for Your Chevy Vehicle:

When selecting coolant for your Chevy vehicle, consider the following factors:

• Vehicle Model and Year: Different Chevy models and years may have specific coolant requirements. Refer to your vehicle’s owner’s manual or consult with a qualified mechanic to determine the recommended coolant type.

• Coolant Type: As discussed earlier, Chevy vehicles generally recommend the use of Dex-Cool OAT coolants. However, some older models may require conventional IAT coolants. Always follow the manufacturer’s recommendations to ensure optimal performance and protection.

• Coolant Color: Dex-Cool coolants are typically orange in color, while conventional IAT coolants are green. Mixing different types of coolants is not recommended, as it can compromise their effectiveness and potentially lead to cooling system issues.

Coolant Maintenance and Replacement:

To maintain the effectiveness of your Chevy vehicle‘s coolant and ensure optimal cooling system performance, follow these maintenance tips:

• Regular Coolant Level Checks: Regularly check the coolant level in the overflow reservoir. The coolant level should be between the “FULL” and “ADD” marks when the engine is cold.

• Coolant System Flush: Every five years or 100,000 miles, flush the cooling system to remove contaminants, rust, and scale buildup. This helps maintain efficient heat transfer and prevents cooling system issues.

• Coolant Replacement: Replace the coolant according to the manufacturer’s recommendations or when it reaches the end of its lifespan. Using old or degraded coolant can compromise cooling system performance and lead to potential problems.

What Happens if You Use the Wrong Coolant?

Using the wrong coolant in your Chevy vehicle can have several negative consequences:

• Reduced Cooling Efficiency: Incorrect coolant may not provide adequate heat transfer, leading to higher engine temperatures and potential overheating.

• Corrosion and Damage: Using incompatible coolant can cause corrosion and damage to metal components within the cooling system, including the radiator, water pump, and engine block.

• Premature Component Failure: Incorrect coolant can accelerate the deterioration of cooling system components, leading to premature failure and costly repairs.

Basics You Wanted To Know

1. What is the difference between IAT and OAT coolants?

IAT coolants use inorganic additives, while OAT coolants use organic acids as additives. OAT coolants typically have a longer lifespan and provide superior corrosion protection compared to IAT coolants.

2. Why does Chevy recommend using Dex-Cool coolant?

Dex-Cool coolants are specifically formulated to provide long-lasting protection against corrosion, cavitation, and scale formation in Chevy vehicles’ cooling systems.

3. How often should I change the coolant in my Chevy vehicle?

Dex-Cool coolants typically last five years or 100,000 miles. However, it’s essential to refer to your vehicle’s owner’s manual for specific recommendations.

4. Can I mix different types of coolants in my Chevy vehicle?

Mixing different types of coolants is not recommended, as it can compromise their effectiveness and potentially lead to cooling system issues. Always use the coolant type specified by the manufacturer.
