How long does it take for the water temperature to normalize after starting the car?

[OCharlotte]

How long it takes for the water temperature to normalize after starting the car depends on the season and humidity conditions. In winter when the weather is colder, it takes about 5 to 10 minutes if the temperature is below 5 degrees Celsius, and 1 to 2 minutes if it's above 5 degrees. If the engine is too cold, the internal oil becomes less lubricating and cannot effectively lubricate the engine. Starting the car in this condition will cause wear on the engine cylinders, shortening the engine's lifespan. The correct method to allow the car's water temperature to reach normal levels is to drive slowly at low speeds. Avoid high RPMs and maintain a low speed, keeping the engine speed below 3000 RPM, generally around 2000 RPM. Otherwise, the severe wear on the engine and transmission may be irreversible. Once the engine temperature rises to the normal operating temperature (which usually takes about 3 to 5 minutes), you can resume normal driving.
