As the world’s most iconic luxury SUV brand, Range Rover is synonymous with unparalleled performance, comfort, and style. With a rich history spanning over five decades, the brand has consistently pushed the boundaries of innovation, engineering, and design. One of the most critical components of a Range Rover’s operation is its cooling system, which relies on a specific type of coolant to maintain optimal engine performance and longevity. In this comprehensive guide, we’ll delve into the world of coolants, exploring the types, benefits, and recommended coolants for your Range Rover.
The Importance of Coolant in Range Rovers
Coolant plays a vital role in maintaining the optimal operating temperature of your Range Rover’s engine. It absorbs and dissipates heat, preventing overheating and damage to critical components. The correct type of coolant is essential to ensure the longevity and reliability of your vehicle. In this section, we’ll explore the different types of coolants available and their characteristics.
What is Coolant?
Coolant is a liquid solution designed to absorb and dissipate heat from your Range Rover’s engine. It’s typically a mixture of water, ethylene glycol, and other additives that provide corrosion protection, freeze protection, and heat transfer properties. Coolant is circulated through the engine block, cylinder head, and radiator to maintain a consistent operating temperature.
Types of Coolant
There are several types of coolants available, each with its unique characteristics and benefits. The most common types include:
- Ethylene Glycol (EG)-based coolants: These are the most common type of coolant used in Range Rovers. EG-based coolants are effective at low temperatures and provide excellent corrosion protection.
- Propylene Glycol (PG)-based coolants: PG-based coolants are used in some Range Rover models and offer improved freeze protection and reduced toxicity.
- Organic Acid Technology (OAT) coolants: OAT coolants are a newer type of coolant that uses organic acids instead of inorganic acids to provide corrosion protection.
- Silicate-based coolants: Silicate-based coolants are not recommended for use in Range Rovers as they can cause corrosion and damage to engine components.
Recommended Coolants for Range Rovers
The recommended coolant for your Range Rover depends on the model year, engine type, and climate. Here are some general guidelines:
| Model Year | Engine Type | Recommended Coolant |
|---|---|---|
| Pre-2006 | Petrol | EG-based coolant (e.g., Prestone Antifreeze) |
| Pre-2006 | Diesel | EG-based coolant with diesel additive (e.g., Castrol Antifreeze) |
| 2006 and later | Petrol | OAT-based coolant (e.g., Toyota Long Life Antifreeze) |
| 2006 and later | Diesel | EG-based coolant with diesel additive (e.g., Castrol Antifreeze) |
