Is the Air Intake Grille Afraid of Water Intrusion on Rainy Days?

[DelCharlie]

If water enters the car's air intake grille, simply wipe it dry as long as it doesn't reach the engine. Only poorly designed air intakes allow water to enter the engine, causing stalling or shaking. Well-designed systems rarely let water into the engine, and even minor water intrusion has no impact. Below are some key points about the air intake grille: 1. Function: The primary roles of the air intake grille are cooling and air intake. If the engine radiator's water temperature gets too high and natural airflow can't fully dissipate the heat, the fan will automatically activate to assist in cooling. 2. Working Process: When the car is running, air flows in reverse, and the fan's airflow direction also reverses. The heated airflow exits from near the windshield behind the engine hood and from beneath the vehicle, effectively expelling the heat.
