Think of this as your Brilliance H330’s “engine cooling guardian”—not just a fan, but a precision cooling tool that stops the engine from overheating during drives. It’s a durable assembly with 4–6 rigid plastic blades (lightweight yet tough), a heat-resistant metal motor housing, and built-in mounting brackets. Mounted behind the radiator in the engine bay, it’s designed to kick in when the engine gets too hot, blowing cool air over the radiator to lower coolant temperature. Without it, your H330’s engine could overheat—leading to costly damage like warped cylinders or blown gaskets, especially in traffic or hot weather.
This radiator fan is
exclusive to Brilliance H330—always check your vehicle’s VIN to confirm fitment! Brilliance tailored it to the H330’s specs: its blade size and airflow match the radiator’s dimensions (maximizes cooling efficiency), its motor power aligns with the engine’s heat output, and its wiring plug connects directly to the H330’s ECU (engine control unit) for automatic operation. Grab a generic fan or one for other models? You’ll face issues: weak airflow (can’t cool the engine), wrong fit (rattles or doesn’t mount), or incompatible wiring (won’t turn on/off at the
right temperature).
As a vital part of the H330’s
cooling system, it does two non-negotiable jobs:
Prevent overheating: The ECU triggers the fan when coolant hits 90–95°C (engine’s “danger zone”). It blows air over the radiator, which cools the circulating coolant—lowering engine temperature back to a safe range (80–90°C) before damage occurs.
Support AC performance: When the air conditioning is on, the fan also cools the nearby AC condenser. This helps the AC blow colder air and reduces extra strain on the engine, keeping both the cooling and AC systems running smoothly.

This H300 3481007 radiator fan only fits Brilliance H330—wrong fit means engine overheating risks:
Replacing this fan doesn’t require advanced skills—here’s how:
Prep: Turn off the H330’s engine and disconnect the battery (avoids electric shocks). Let the engine cool completely (radiator gets hot—don’t touch it while warm).
Remove old fan: Unplug the wiring plug from the back of the fan motor. Remove the 4–6 bolts holding the fan’s brackets to the radiator frame. Gently pull the old fan away from the radiator (it sits flush—no forcing needed).
Install new fan: Position H300 3481007 against the radiator, align the brackets with the frame holes, and tighten the bolts. Plug the wiring back in (it clicks when secure).
Test: Reconnect the battery, start the engine, and let it idle until it warms up. The fan should turn on automatically when coolant hits 90–95°C (use a temperature gauge to check). Turn on the AC to confirm the fan activates immediately.
Clean blades every 3 months: Wipe the fan blades with a dry cloth to remove dust, debris, or bugs (build-up reduces airflow and strains the motor).
Inspect blades yearly: Check for cracks or bending—damaged blades don’t move enough air (replace the fan if blades are compromised).
Listen for abnormal noise: A loud whirring or grinding sound means the motor is wearing out (replace the fan before it stops working).
Check wiring every 6 months: Inspect the plug and wiring for corrosion or fraying (bad connections cause the fan to malfunction)

As Brilliance H330’s “engine cooling guardian,” this radiator fan is a durable assembly with rigid plastic blades, a heat-resistant motor housing, and mounting brackets. Mounted behind the radiator, it’s exclusive to H330 (confirm via VIN), syncing with the ECU and matching the radiator’s dimensions.
Key roles: Activate automatically at 90–95°C to cool coolant (preventing engine overheating); support AC performance by cooling the condenser.
It fits all H330 variants but not other Brilliance models (e.g., H230, V3), non-Brilliance vehicles, or H330 with modified cooling systems/engines.
Installation is DIY-friendly (30–45 mins): Disconnect battery, remove old fan, install H300 3481007, test. Maintenance: Clean blades quarterly, inspect blades yearly, check for abnormal noise, examine wiring every 6 months.
Original fans ensure efficient cooling and ECU sync—aftermarket ones risk weak airflow, poor fit, or premature failure.
