First, let’s define its critical role: the
Chery FX Radiator Fan 302000842AA isn’t just a “cooling fan”—it’s the
active heat dissipator for the vehicle’s engine cooling system, mounted behind the radiator in the FX’s engine bay. Think of it as a high-efficiency electric fan (paired with a protective shroud) designed to pull cool air through the radiator. Its main job? To lower the temperature of hot coolant flowing through the radiator—especially when the car is stationary (no natural airflow) or in slow traffic—preventing engine overheating. Without it, the engine can quickly overheat, leading to costly damage like warped cylinders or blown gaskets.
This radiator fan is exclusively engineered for the Chery FX—always confirm with your vehicle’s VIN! It’s tailored to match the FX’s cooling system needs: its airflow capacity aligns with the engine’s heat output (no under/over-cooling), its mounting points fit the radiator shroud perfectly (no vibrations), and its wiring syncs with the FX’s temperature sensor (auto-starts/stops based on coolant temp). A generic radiator fan? You’ll face issues: it’ll move too little air (engine overheats), vibrate loudly (damages the radiator), or fail to auto-adjust (wastes battery power)—undermining the cooling system’s efficiency.
Its role is heat-focused and responsive—here are 3 key tasks it performs for your Chery FX:
Auto-adjusts to coolant temp: The FX’s engine temperature sensor triggers the fan to turn on when coolant hits ~90–95°C (prevents overheating) and off when it drops to ~85°C (saves battery). No manual control needed—it works automatically.
Boosts airflow at low speeds: When the car is idling or moving slowly (e.g., city traffic), there’s little natural air through the radiator. The fan pulls cool air through, ensuring coolant stays cool even in stop-and-go conditions.
Supports air conditioning (AC): When the AC is on, the fan runs more frequently to cool both the engine coolant and the AC’s condenser (mounted near the radiator)—keeping the cabin cool while protecting the engine.

This 302000842AA radiator fan is only for the Chery FX—wrong fit = cooling system failure:
Improper installation risks electrical damage or fan failure:
Disconnect the battery: Technicians first disconnect the FX’s battery to avoid short circuits, then remove the old fan’s wiring and mounting bolts.
Mount the new fan: They align 302000842AA with the radiator shroud’s mounting points, bolt it securely, and reconnect the temperature sensor wiring.
Test functionality: They start the engine, monitor coolant temp, and confirm the fan turns on/off at the correct temperatures. They also check for vibrations or unusual noise.
Clean blades monthly: Wipe dust, leaves, or bugs from the fan blades (debris blocks airflow—reduces cooling efficiency).
Check wiring quarterly: Inspect the sensor connector for loose plugs or frayed wires (vibration can damage wiring—causes fan to stop working).
Replace every 5–7 years: Even if the fan works, its motor and blades wear over time (reduced airflow—risk of overheating in extreme conditions).
Avoid water damage: Ensure the fan’s wiring is sealed (water in the connector causes short circuits—fan fails suddenly).

Exclusive to Chery FX (confirm via VIN), this radiator fan is the “engine’s active cooling guard”: mounted behind the radiator, it auto-starts at 90–95°C (stops at 85°C) to pull cool air, prevents overheating in idling/traffic, and supports AC by cooling the condenser.
It has a high-torque 12V motor, reinforced plastic blades, and a protective shroud. Maintain by cleaning blades (monthly), checking wiring (quarterly), and replacing every 5–7 years. Aftermarket fans lack airflow or auto-sync—only the original ensures efficient, safe cooling.
