Can Idle Speed Cause Overheating?

[GabrielFitz]

Idle speed can cause overheating. Symptoms: The engine temperature gauge needle swings into the red zone; the cooling fan operates at maximum speed; insufficient coolant; sudden loss of power while driving, accompanied by severe knocking and piston slapping sounds, mostly caused by engine overheating. The normal operating temperature of an engine is between 85-95 degrees Celsius. When the temperature is too high, the viscosity of the engine oil decreases, reducing its lubricating performance. High-speed components like pistons and valves are prone to deformation, resulting in a loss of engine power. Solutions: If overheating is caused by coolant loss, a small amount of distilled water can be added as an emergency measure. For overheating issues caused by prolonged driving, pull over to the side of the road, turn on the hazard warning lights, and allow the vehicle to cool down naturally.
