What are the aftereffects of repairing an overheated engine?

[EverettLynn]

Engine overheating repair aftereffects include increased component wear. Below is relevant information about the hazards caused by excessive engine temperature: 1. Increased component wear: Lubricating oil oxidizes and deteriorates due to high temperatures, with gum and deposits adhering to friction surfaces such as piston rings, cylinder walls, and other parts, reducing thermal conductivity. The viscosity of lubricating oil decreases, oil pressure drops, lubrication performance worsens, and the strength of the oil film on cylinder walls weakens under impact loads, thereby increasing component wear. 2. High temperature judgment: The engine has its own operating temperature, with most cars operating between 80-90 degrees Celsius. To maintain this temperature, the car's cooling system must function properly. The temperature displayed on the car's dashboard is actually the temperature of the coolant in the cooling system, which directly reflects the engine's temperature condition. If the temperature gauge does not exceed the red indicator line on the dashboard, it is normal. If it exceeds this line, it indicates the engine is overheating.
