What is the normal range for coolant temperature?
1 Answers
Coolant temperature between 75-98 degrees Celsius is considered the normal range. Here are the detailed explanations: 1. When the engine is cold and just started, the coolant temperature is the same as the ambient temperature. 2. After 3-5 minutes of engine warm-up operation, the coolant temperature will gradually rise and enter the working temperature range of 75-98 degrees Celsius. 3. The specific working temperature range may vary depending on the vehicle model or driving style. For example, high-performance engines or engines in sport driving mode may operate at slightly higher temperatures. 4. If the coolant temperature exceeds the engine's normal operating temperature, the engine coolant temperature warning light will illuminate on the dashboard. Common causes of overheating include insufficient or deteriorated antifreeze, damaged thermostat, faulty coolant temperature sensor, clogged radiator, or malfunctioning cooling fan.
