Why does the engine compartment fan keep running after locking the car?

[McBrody]

Because turbocharged vehicles have a delayed fan shutdown feature. Below is relevant information about the engine compartment: 1. Overview: The engine compartment generally includes components such as the engine, air filter, battery, engine exhaust system, throttle valve, coolant reservoir, relay box, brake booster, throttle cable, windshield washer fluid reservoir, brake fluid reservoir, fuses, etc. 2. Components: Air filter (full name: air cleaner). A car cannot operate without the engine working, and the engine relies on the energy generated by fuel combustion, which requires extremely clean air for combustion. The air filter is the main component that provides clean air to the engine. The lifespan of an air filter is related to usage frequency and environment. Generally, for ordinary family cars, the air filter element should be replaced during each maintenance service.
