@dadokfuwnv9: 💧 Water Pump Working ⚠️ First 4 Seconds: The engine starts, spinning the crankshaft and serpentine belt, which drives the water pump. Coolant begins flowing through the engine block, absorbing heat. 🌡️ ✅ Last 4 Seconds: The thermostat opens, allowing hot coolant to flow into the radiator where it cools down before circulating back through the engine, keeping it at the ideal temperature. ❄️🚗 How does your engine stay cool?
