Lexus, a luxury vehicle brand, has built a reputation for its high-performance engines and innovative technology. However, one crucial aspect of maintaining a Lexus vehicle is ensuring the proper coolant is used. Coolant plays a vital role in regulating engine temperature, preventing corrosion, and maintaining optimal engine performance. With so many options available in the market, it can be overwhelming to determine the correct coolant for your Lexus. In this article, we will delve into the world of coolants and explore what coolants Lexus uses, the benefits and drawbacks of each, and provide practical advice on how to choose the right coolant for your vehicle.
What Coolant Does Lexus Use?
Background Information
Lexus vehicles are equipped with a range of engines, from the 2.0-liter inline-four to the 5.0-liter V8. Each engine requires a specific type of coolant to ensure optimal performance and longevity. Lexus uses a combination of ethylene glycol and propylene glycol-based coolants, which provide excellent heat transfer properties and corrosion protection.
Ethylene Glycol-Based Coolants
Ethylene glycol-based coolants are the most commonly used type of coolant in Lexus vehicles. They are a mixture of ethylene glycol, water, and additives that provide excellent heat transfer properties and corrosion protection. Ethylene glycol-based coolants are effective in a wide range of temperatures and are suitable for use in both conventional and hybrid engines.
- Benefits:
- Excellent heat transfer properties
- Corrosion protection
- Wide temperature range
- Drawbacks:
- May cause damage to engine components if not properly mixed

Propylene Glycol-Based Coolants
Propylene glycol-based coolants are a newer type of coolant used in some Lexus vehicles. They are a mixture of propylene glycol, water, and additives that provide excellent heat transfer properties and corrosion protection. Propylene glycol-based coolants are biodegradable and non-toxic, making them a more environmentally friendly option.
- Benefits:
- Excellent heat transfer properties
- Corrosion protection
- Biodegradable and non-toxic
