The 2018 Jeep Grand Cherokee is a popular SUV known for its ruggedness, off-road capabilities, and impressive engine performance. However, like any vehicle, it requires regular maintenance to ensure optimal performance and longevity. One critical component of this maintenance is the coolant system, which plays a vital role in regulating engine temperature and preventing damage. Choosing the right coolant for your 2018 Jeep Grand Cherokee can be a daunting task, especially with the numerous options available in the market. In this article, we will delve into the world of coolants and provide you with a comprehensive guide on what kind of coolant is suitable for your vehicle.
Understanding Coolants
Coolants are designed to absorb and transfer heat away from the engine, preventing overheating and damage. They are typically made up of a mixture of water, ethylene glycol, and other additives. The type of coolant used in your 2018 Jeep Grand Cherokee depends on various factors, including the engine type, climate, and driving conditions.
Types of Coolants
Coolants can be broadly classified into two categories: conventional coolants and hybrid coolants.
- Conventional Coolants: These coolants are made up of a mixture of water and ethylene glycol. They are suitable for most vehicles and provide good cooling performance.
- Hybrid Coolants: These coolants are designed to provide improved cooling performance and are suitable for high-performance vehicles. They are made up of a mixture of water, ethylene glycol, and other additives.
Coolant Properties
Coolants have several properties that make them suitable for use in vehicles. Some of the key properties include:
- Boiling Point: This is the temperature at which the coolant starts to boil. A higher boiling point indicates better cooling performance.
- Freezing Point: This is the temperature at which the coolant starts to freeze. A lower freezing point indicates better cold-weather performance.
- Viscosity: This is the thickness or flowability of the coolant. A lower viscosity indicates better flowability and better cooling performance.
- Corrosion Inhibition: This is the ability of the coolant to prevent corrosion and damage to engine components. A good coolant should have good corrosion inhibition properties.
