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

[VonCatherine]

In summer, the temperature in the engine compartment can reach at least 60-70 degrees Celsius, which is within the normal range. The circuits in the engine compartment mainly consist of capacitors, resistors, and transistors. Below is an introduction to the temperature tolerance of these components: 1. Capacitors: The most heat-sensitive are electrolytic capacitors, with a tolerance temperature not exceeding 105 degrees Celsius. 2. Resistors: Metal oxide film resistors, depending on their power rating, can withstand temperatures between 125-235 degrees Celsius. 3. Transistors: The high-temperature limit for silicon PN junctions is generally 175 degrees Celsius; the lower the temperature, the significantly increased lifespan and reliability.
