Both antifreeze and coolant play crucial roles in your vehicle’s cooling system. While they may seem similar, they serve different purposes and have unique properties.

This segment delves into the distinct roles of antifreeze and coolant in keeping your car’s engine running, highlighting differences in their concentration levels and application.

Firstly, we’ll examine the function of antifreeze within your vehicle’s cooling system.

Role of Antifreeze

Antifreeze, also known as antifreeze coolant, plays a vital role in safeguarding your car’s engine from freezing and overheating. Its primary ingredient is ethylene glycol, which helps lower the freezing point of the coolant liquid in the radiator, lubricate the water pump, and inhibit corrosion.

Antifreeze types typically contain corrosion inhibitors to protect engine parts from rust. Additionally, they help prevent other forms of corrosion. With the help of antifreeze, your car’s engine can operate smoothly in sub-zero weather conditions, preventing costly damage and ensuring optimal performance.

Role of Coolant

Coolant, on the other hand, is a mixture of water and antifreeze that circulates through the engine to regulate temperature and prevent damage. The primary component of both engine coolant and antifreeze is ethylene glycol. Coolant is essential for maintaining the engine’s temperature in both hot and cold conditions, ensuring your car runs efficiently and preventing potential damage.

Remember, maintaining the right coolant concentration is key to achieving optimum engine performance. It is suggested to use 50% water and 50% antifreeze in the coolant mixture. This will ensure optimal performance of the engine. This balance helps protect your engine from freezing in cold temperatures and overheating in hot conditions.

Antifreeze vs. Coolant: The Key Differences

A car's engine with a cooling system and radiator fluid

Having understood the roles of antifreeze and coolant, let’s examine their significant differences. These differences include concentration levels, additives, and their specific usage in your vehicle’s cooling system.

Understanding these distinctions can help you make informed decisions about which product to use and how to maintain your vehicle’s engine effectively.

Concentration Levels

As mentioned earlier, antifreeze is a concentrated liquid solution, while coolant is a diluted combination of antifreeze and water. The concentration levels of glycol in antifreeze are higher, providing protection against freezing temperatures. Conversely, coolant has a lower concentration of glycol, which helps protect against overheating.

Adhering to the suggested water-to-antifreeze ratio in your coolant mixture is vital for maintaining peak engine performance. Failing to do so could result in engine damage or reduced efficiency.

Additives from LIQUI MOLY for Antifreeze and Coolant

LIQUI MOLY, a renowned German manufacturer of automotive chemicals and lubricants, offers a comprehensive selection of additives for antifreeze and coolant. These additives can help improve the performance of your antifreeze and coolant, ultimately providing greater cost-efficiency and engine protection.

LIQUI MOLY Radiator Cleaner is a useful and high quality coolant additive to be used before draining old coolant

Some examples of LIQUI MOLY additives include:

  • Radiator stop leak

  • Coolant additives to remove blockages and enhance cooling performance

  • Radiator cleaner to eliminate impurities

  • Premixed antifreeze

  • Radiator antifreeze based on ethylene glycol

Usage

Antifreeze and coolant serve different purposes in your vehicle’s cooling system. Antifreeze, primarily composed of ethylene glycol or propylene glycol, is employed to prevent the coolant from freezing in low temperatures. On the other hand, coolant, a mixture of antifreeze and water, is utilized to regulate the engine’s temperature and prevent overheating.

In addition to maintaining the engine’s temperature, coolant also helps lubricate the water pump and keep the heater core functioning properly. By understanding the specific usage of antifreeze and coolant, you can better maintain your vehicle’s cooling system and prevent potential engine damage.

Types of Antifreeze and Coolant

There are three main types of antifreeze and coolant available in the market: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). Each type has its unique properties and advantages, making it essential to choose the right one for your vehicle.

Next, we’ll delve into the specifics of each type of antifreeze and coolant.

IAT (Inorganic Additive Technology)

Inorganic additive technology (IAT) coolants are traditional green coolants that contain inorganic corrosion inhibitors. These coolants are formulated with ethylene glycol and are generally more affordable and accessible compared to other types.

While IAT coolants offer adequate protection against freezing and overheating, they do not have the same longevity as OAT coolants. Therefore, frequent replacement of IAT coolants is necessary to sustain peak engine performance.

OAT (Organic Acid Technology)

Organic Acid Technology (OAT) coolants:

  • Long-life coolants

  • Feature organic corrosion inhibitors

  • Often orange or red in color

  • Composed of propylene glycol

  • Offer a longer lifespan than IAT coolants due to their organic acids not breaking down as quickly as the silicates in IAT coolants.

While OAT coolants provide enhanced protection and longevity, they can be more expensive than IAT coolants. It’s important to weigh the benefits and costs of each type of coolant before making a decision.

HOAT (Hybrid Organic Acid Technology)

Hybrid Organic Acid Technology (HOAT) coolants:

  • Are a combination of IAT and OAT coolants

  • Offer the advantages of both IAT and OAT coolants

  • Provide a longer lifespan and improved protection compared to IAT and OAT coolants

To ensure you’re using the correct HOAT coolant for your vehicle, it’s recommended to consult your vehicle’s owner’s manual or seek professional advice. This will help you make an informed decision and maintain your vehicle’s cooling system effectively.

Choosing the Right Antifreeze and Coolant for Your Vehicle

Checking your vehicle’s coolant levels regularly is crucial for maintaining optimal engine performance and preventing potential damage. It’s recommended to evaluate your coolant levels every time you refuel your vehicle or at least every couple of weeks.

If your coolant level is below the “full” line, you’ll need to add more coolant, using a 50/50 mix of antifreeze and water until it reaches the “full” line. This will help protect your engine from freezing in cold temperatures and overheating in hot conditions.

Flushing the Radiator

Flushing the radiator is an essential part of routine vehicle maintenance, as it helps remove contaminants and maintain the efficiency of your cooling system. It’s recommended to replace the radiator fluid every two years or 24,000 miles.

To flush the radiator, follow these steps:

  1. Open the drain valve or loosen the clamp and ensure a drain pan is placed underneath to collect the coolant.

  2. Once the old coolant has been drained, flush the cooling system with a cooling system cleaner.

  3. Refill the radiator with fresh coolant.

Addressing Cooling System Issues

If you encounter any issues with your vehicle’s cooling system, it’s important to address them promptly to avoid costly repairs and potential damage. This may include checking for leaks, inspecting the water pump, or assessing the radiator for any signs of damage or corrosion.

If you’re unsure about how to address a cooling system issue, it’s recommended to seek professional help from a trusted mechanic or dealership. They can diagnose the problem and provide the necessary repairs or maintenance to keep your vehicle running smoothly.
