📌 Engine Cooling System Parts Explained: How Each Component Keeps Engine Cool:
🔹 Radiator – Transfers heat from the coolant to the outside air to keep the engine cool.
🔹 Water Pump – Circulates coolant through the engine and radiator to maintain a stable temperature.
🔹 Thermostat – Regulates coolant flow by opening and closing based on engine temperature.
🔹 Hose – Flexible tubes that carry coolant between the engine, radiator, and other components.
🔹 Pressure Cap – Seals the cooling system and maintains pressure to raise the coolant’s boiling point.
🔹 Freeze Plug – Metal plugs that prevent engine block cracking by allowing expansion if coolant freezes.
🔹 Temperature Sensor – Monitors coolant temperature and sends data to the engine control unit or dashboard.
🔹 Cooling Fan – Draws air through the radiator to enhance cooling, especially at low speeds or idle.
