The Radiator Coolant Tank holds excess coolant and supplies it back to the radiator when required to maintain a consistent engine temperature. It functions as a buffer system that balances coolant expansion and contraction caused by heat changes during engine operation. It keeps the coolant level stable, ensuring continuous circulation through the radiator and engine block, preventing overheating and fluid loss.Attributes:• Prevents coolant overflow through expansion management during high temperatures. • Protects engine components from thermal stress caused by heat spikes.• Helps maintain balanced pressure between the radiator and tank for stable function.Applications: The Radiator Coolant Tank stores excess coolant and regulates its flow back to the radiator, maintaining stable engine temperature and efficient cooling performance.
