Range Rover engine coolant type – the correct type to use

The Range Rover engine coolant type you should be using is Ethylene glycol-based antifreeze and coolant with OAT (Organic Additive Technology) inhibitors.

In this article, I will cover everything you need to know about the coolant type for your Range Rover engine, including its importance, types of coolants available, and how to properly maintain your coolant system.

What models are affected?

Importance of engine coolant

The engine coolant plays a crucial role in maintaining the temperature of the engine, preventing it from overheating.

It circulates through various components of the engine system, absorbing heat and dissipating it through the radiator.

Without the right coolant type, your Range Rover’s engine could suffer from overheating, which can lead to severe engine damage.

Range Rover Coolant Types

There are several types of coolant available for Range Rover engines. Let’s take a closer look at the most commonly used coolant types:

1. Ethylene Glycol-Based Coolant

Ethylene Glycol-based coolants are the most popular choice for Range Rover engines, mainly due to their excellent heat transfer properties.

They have a high boiling point, which helps prevent the coolant from evaporating even at high temperatures.

Additionally, they offer excellent corrosion protection, preventing rust and other damages to the engine components.

2. Organic Acid Technology (OAT) Coolant

Organic Acid Technology (OAT) coolants are another commonly used coolant type for Range Rover engines.

They consist of a mixture of organic acids and additives, providing excellent corrosion protection for modern aluminum and cast-iron engines.

OAT coolants are known for their extended lifespan, typically lasting up to 5 years or 150,000 miles, whichever comes first.

3. Hybrid Organic Acid Technology (HOAT) Coolant

Hybrid Organic Acid Technology (HOAT) coolants are a blend of ethylene glycol and organic acid technology additives.

They offer improved performance in terms of heat transfer and corrosion protection compared to traditional ethylene glycol coolants.

HOAT coolants are commonly used in newer Range Rover models and are designed to provide long-lasting protection.

It’s important to note that different Range Rover models and engines may have specific coolant requirements.

Therefore, it’s always recommended to consult your owner’s manual or contact a certified Range Rover service center to ensure you are using the correct coolant type for your vehicle.

Maintaining Your Coolant System

Proper maintenance of your Range Rover’s coolant system is essential to keep your engine running smoothly.

Here are some tips to help you maintain your coolant system:

1. Regular inspections

Regularly check the coolant level and inspect for any leaks or signs of coolant degradation.

Low coolant levels or coolant leaks can lead to overheating and engine damage.

2. Flush and replace coolant

Coolants usually require replacement every 2 to 5 years, depending on the type.

Flushing the system and replacing the coolant helps remove any contaminants or debris that can impact its performance.

3. Follow manufacturer guidelines

Always follow the manufacturer’s recommended coolant change intervals and procedures.

Each Range Rover model may have specific recommendations, so it’s important to adhere to them for optimal performance.

4. Use distilled water

When adding coolant to your Range Rover, it’s essential to use distilled water to dilute the coolant concentrate.

Tap water may contain minerals and impurities that can affect the coolant’s effectiveness.

5. Visually inspect hoses and connections

Regularly check the coolant hoses and connections for any signs of wear, leaks, or damage.

Faulty hoses can lead to coolant loss, resulting in engine overheating.

By following these maintenance tips, you can ensure that your Range Rover’s coolant system remains in top condition, protecting your engine from potential damage.


How often should I check the coolant level in my Range Rover?

Regularly check the coolant level at least once a month or before long trips to ensure proper engine cooling.

What should I do if I notice a coolant leak?

If you spot a coolant leak, it’s crucial to address it promptly. Consult a mechanic to identify and fix the source of the leak.

Can I mix different coolant types in my Range Rover?

Mixing different coolant types can lead to issues. Stick to the coolant recommended in your vehicle’s manual for best results.

Should I use a coolant flush additive?

Using a coolant flush additive can help clean the cooling system, but follow manufacturer guidelines and consult a professional if needed.
