A vehicle’s cooling system is responsible for maintaining the correct operating temperature of the engine. When the cooling system fails to operate properly, over-heating or freeze-up may occur. Replacing your vehicle’s coolant at recommended intervals will help prevent over-heating in warm weather, freeze-up in cold weather, and will provide protection from rust and corrosion. At Express Lube Greenbriar, we provide more than a simple drain and fill of the radiator. Our Coolant Exchange Service is designed to replace your vehicle’s old coolant from the entire cooling system. Express Lube Greenbriar recommends following your service manufacturer’s recommended interval when replacing your vehicle’s coolant.
