Can I use green coolant in a Toyota?

Understanding Coolant Types and Toyota Recommendations


Coolant, also known as antifreeze, is a crucial fluid in a vehicle's cooling system. It helps regulate the engine temperature and prevent overheating. Different types of coolants are designed for specific vehicle makes and models, and it's important to use the right one to ensure optimal performance and longevity of the cooling system.
