Car fan noise can be caused by: 1. Dirty air conditioning filter; 2. Debris in the blower fan blades; 3. Deformed air conditioning fan blades or damaged fan motor; 4. Worn clutch bearing in the air conditioning pump; 5. Loose screws due to blower vibration; 6. Collision between fan blades and other components; 7. Foreign objects in the air duct; 8.

The car radiator, which is part of the cooling system, consists of three parts: the inlet chamber, outlet chamber, main plate, and radiator core in the engine water cooling system.
