Is it okay for the engine compartment to be hot in summer?

No, it's not okay. The normal temperature range for an engine compartment is between 85-90 degrees Celsius. When the engine temperature is too high, it can reduce engine power and increase fuel consumption. Below is an introduction to the hazards caused by excessive engine temperature: 1. Accelerated wear of mechanical parts: Engine oil can oxidize and deteriorate due to high temperatures, forming deposits and sludge that adhere to the piston rings, cylinder walls, and other friction surfaces, reducing thermal conductivity. The viscosity of the engine oil decreases, oil pressure drops, and lubrication performance deteriorates. The oil film on the cylinder walls weakens under impact loads, further accelerating the wear of mechanical parts. 2. High temperature judgment: Engines have their own operating temperature range, 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. As long as the temperature gauge does not exceed the red indicator line on the dashboard, it is considered normal. If it exceeds this line, it indicates that the engine temperature is too high.
