What is the normal engine temperature?

[DeEthan]

The normal operating temperature for an engine is typically around 90°C as the optimal range. However, engine temperature varies under different working conditions. Considering both cold-start and warmed-up states, the normal engine temperature range is between 85-105°C, with the ideal state hovering around 90°C. When the engine temperature becomes too high, the coolant temperature warning light on the dashboard will illuminate, and sometimes white smoke may emerge from the engine compartment. If this occurs, follow these steps: Step 1: Find a safe place to pull over and let the vehicle idle. Do not turn off the engine, as shutting it down would stop both the cooling fan and coolant circulation, which could make the engine even hotter. Step 2: Open the hood to increase air circulation. After the water temperature drops slightly, loosen the radiator cap one notch to release internal steam before fully opening it. Step 3: Do not add coolant immediately. As we know from physics, materials expand when heated. Boiling water in a sealed container creates pressure - if you open the radiator cap immediately, the pressurized hot water could spray out and cause burns. Step 4: Check for leaks in the radiator hoses and inspect the coolant level. If no coolant is available in the vehicle, you can temporarily use bottled water as a substitute, but remember to replace it with proper coolant later. Step 5: For an overheating engine, the most an average person can do is check and add coolant. For other issues like water pump or thermostat failures, it's best to call for professional assistance.
