What is the normal operating temperature for a car's engine coolant?

[DelAlaina]

Car engine coolant temperature between 80 to 90 degrees Celsius is considered normal for driving. Below are relevant details about engine coolant temperature: 1. Both excessively high or low coolant temperatures can easily damage the engine. Low temperatures are detrimental to engine lubrication, while high temperatures may cause engine self-ignition. 2. During daily driving, pay attention to the coolant temperature warning light on the dashboard. If the red light illuminates, do not continue driving - pull over to let the engine cool down. The coolant temperature gauge typically ranges from 0 to 130°C, with the normal operating temperature at the central 90°C mark. After starting the vehicle, the coolant temperature rises quickly. When the needle reaches the central position, the temperature stabilizes. Generally, it's optimal to start driving when the temperature reaches the middle position.
