This genuine OEM Yamaha radiator coolant overflow reservoir bottle is an important part of the motorcycle cooling system. Made from durable high-density polyethylene plastic, it stores excess coolant as engine temperature rises and returns fluid to the radiator as the engine cools. Molded FULL and LOW level marks allow quick coolant checks.
