Normal engine temperature varies from one car to another and from one manufacturer to another. There are multiple scales, not just one. Many factors influence engine temperature. It can be described as the normal engine temperature.
Describing it as normal depends on your own perception of your car’s engine. The temperature may be normal for you in another car, but it may not be normal for it, and it may even be high. Therefore, considering engine temperature normal or abnormal is a relative matter that varies depending on the engine and the car.
The fixed scale by which we distinguish between normal and abnormal temperatures is the maximum or highest temperature, symbolized by the letter “hot” (H). Anything below this temperature can be considered normal or slightly higher than normal, or slightly cold or cool, which is the minimum temperature, symbolized by the letter “cold” (C).
If the engine temperature reaches the red line, or the maximum temperature, it can lead to partial or total engine damage. The impact varies depending on the engine’s operating time, maintenance methods and quality, and operating conditions.
Any driver or car owner can distinguish between the normal engine temperature, which it reaches during most operations, and the abnormal temperature, which poses a significant risk to the engine and must be avoided.
Some modern cars, such as some BMWs and Mercedes-Benzes, do not have an engine temperature gauge. Once the temperature reaches a standard level, a light appears on the dashboard and the engine shuts down.
