Coolant & Additives

Coolant & Additives: Explained

When it comes to maintaining the performance and longevity of your vehicle, the cooling system plays a crucial role. At the heart of this system are coolant and additives, which work together to regulate engine temperature and prevent overheating. This page is dedicated to providing you with a comprehensive understanding of these essential components, their benefits, and how to choose the right ones for your vehicle.

Understanding Coolant & Additives

Coolant, also known as antifreeze, is a liquid that circulates through your car's engine to absorb heat and dissipate it through the radiator. It's a mixture of water and ethylene or propylene glycol, which helps to lower the freezing point and raise the boiling point of the liquid, ensuring optimal engine performance in all weather conditions.

Additives, on the other hand, are substances added to the coolant to enhance its properties. They help to prevent rust and corrosion, lubricate the water pump, and maintain the pH balance of the coolant, among other functions.

Benefits of Using Quality Coolant & Additives

Investing in high-quality coolant and additives can offer several benefits:

  • Temperature Regulation: They help to maintain an optimal engine temperature, preventing overheating and freezing.
  • Engine Protection: They protect the engine and cooling system components from rust, corrosion, and cavitation.
  • Improved Performance: They can enhance the overall performance and efficiency of your vehicle.
  • Extended Lifespan: They can extend the lifespan of your engine and cooling system components.

Choosing the Right Coolant & Additives

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

  • Vehicle Specifications: Always refer to your vehicle's owner manual for specific coolant and additive recommendations.
  • Antifreeze Type: There are different types of antifreeze available, including IAT (Inorganic Additive Technology), OAT (Organic Acid Technology), and HOAT (Hybrid Organic Acid Technology). Each type has its unique properties and compatibility.
  • Additive Properties: Look for additives that offer rust and corrosion protection, pH balance maintenance, and water pump lubrication.

Installation and Maintenance

While installing coolant and additives is a straightforward process, it's essential to follow the correct steps and safety precautions. Always ensure the engine is cool before opening the radiator cap to prevent injury from hot coolant. Regularly check the coolant level and condition, and replace it as per the manufacturer's recommended schedule.
