Is 100 Degrees Considered High Temperature for a Diesel Engine?

[AlejandroAnn]

Diesel engines reaching 100 degrees is considered high temperature. The normal operating temperature range for a diesel engine is between 80°C and 90°C. Additional information: 1. Coolant Temperature Gauge: Generally, the water temperature indicated in a car engine does not refer to the actual water temperature but rather the temperature of the coolant. On the car's dashboard, there is usually a coolant temperature gauge. Engine coolant temperature gauges typically use either physical or virtual dial pointers for display. Some vehicles may not have a temperature gauge and only show a warning indicator when the temperature is excessively high. 2. Causes of High Temperature: If the thermostat is damaged and remains closed, the engine's internal coolant circulates in a small loop, preventing the coolant in the radiator from participating in the cooling cycle. This results in higher temperatures when the vehicle is idling or driving at low speeds, with the temperature increasing further as the speed rises.
