The hoses and pipes in BMW's cooling system serve as the "circulatory network" that regulates the engine's optimal operating temperature, playing a critical role in coolant transfer and heat dissipation.

Hoses and pipes in the cooling system are responsible for circulating coolant (a 50/50 mix of antifreeze and water), fulfilling three vital purposes:

• Heat Transfer: Channel excess heat from the engine block (operating temperature: 80-110℃) to the radiator, where it is dissipated into the ambient air via cooling fins.
• Circulation Integrity: Link key components such as the expansion tank, water pump, and engine water jackets to form a sealed loop, ensuring coolant flows steadily under 1-1.5bar of pressure.
• Temperature Regulation: Work in tandem with the thermostat to restrict coolant flow to the radiator during cold starts (accelerating engine warm-up) and open fully once operating temperature is reached (preventing overheating).
