Is All Coolant the Same/Universal? Differences and Importance of Choosing the Right Coolant

Coolant plays a critical role in maintaining the optimal temperature of your vehicle's engine. It helps prevent overheating and freezing, ensuring smooth engine performance. However, not all coolant is the same or universal. There are different types of coolant available, each with its own composition and specifications. 

In this blog post, we will delve into the differences between coolants and emphasize the importance of selecting the right coolant for your vehicle. Here are the main types of coolants that will be covered by the blog:

  1. Ethylene Glycol-Based 
  2. Propylene Glycol-Based
  3. Hybrid Organic Acid Technology (HOAT)
  4. Dex-Cool

1. Ethylene Glycol-Based Coolant

Ethylene glycol-based coolant is one of the most common types of coolant used in vehicles. It is known for its excellent heat transfer properties and ability to prevent freezing and boiling. This type of coolant is typically green in color, but it can also be orange or yellow depending on the additives and corrosion inhibitors used. Ethylene glycol-based coolants are widely available and suitable for most conventional engines.

2. Propylene Glycol-Based Coolant

Propylene glycol-based coolant is an alternative to ethylene glycol-based coolant, offering similar antifreeze and heat transfer properties. It is often used in applications where there are concerns about toxicity and environmental impact. Propylene glycol-based coolants are typically less toxic than their ethylene glycol counterparts, making them a popular choice in certain industries. However, they may have a higher price point compared to ethylene glycol-based coolants.

3. Hybrid Organic Acid Technology (HOAT) Coolant

HOAT coolants are a combination of organic acids and traditional inhibitors. They offer extended service life and enhanced protection against corrosion for both aluminum and iron components. HOAT coolants are commonly used in vehicles with aluminum engines or components. It is important to follow the manufacturer's recommendations when using HOAT coolants to ensure compatibility with your vehicle.

4. Dex-Cool Coolant

Dex-Cool coolant is a specific type of coolant developed by General Motors. It is an extended-life coolant designed for use in GM vehicles. Dex-Cool coolants are usually orange or red in color and offer superior corrosion protection. However, it is important to note that Dex-Cool coolants are formulated specifically for GM vehicles and may not be compatible with other vehicle makes.
