Core Functions

1. Force air flow through radiator to dissipate engine coolant heat, maintain normal operating water temperature
2. Assist AC condenser heat exchange, reduce high-side refrigerant pressure to guarantee stable cold air output
3. Dual fan coordinated speed adjustment: low speed for normal temperature, full speed under heavy load/high ambient temperature
4. Built-in electronic control module self-protection: cut off power automatically in case of overheating or short circuit to avoid burnout
5. Reduce engine knock risk, prevent overheating damage to cylinder head and turbocharger under climbing or traffic jam conditions

Common Malfunctions Resolved

• Engine high water temperature warning light on, boiling coolant under idle or traffic jam
• AC cooling weak, high pressure alarm when vehicle stationary
• Fan abnormal buzzing, rattling noise or stuck blade
• Fan only runs at full speed without variable speed adjustment, increased fuel consumption
• Fan control module burnout leading to complete fan shutdown and engine overheat
• Water temperature fluctuation, unstable cooling effect with AC turned on

Product Advantages

1. Authentic BROSE factory original assembly, identical motor performance and control logic to vehicle factory fitted spare parts
2. Complete integrated shroud + dual fan + control module one-piece unit, eliminate separate matching of individual parts
3. High temperature reinforced plastic fan housing, anti-deformation under long-term engine heat radiation
4. PWM infinitely variable speed design, lower running noise and less power consumption compared to single-speed fan
5. 1:1 matched original mounting holes, wiring plug and fixed brackets, zero modification during installation
6. Strict durability aging test before delivery, effectively avoid premature fan failure complaints

Package Includes

Installation Guidance

1. Cool down engine completely before operation to avoid scalding from high-temperature coolant
2. Remove front bumper, lower underbody guard and radiator upper cross beam
3. Disconnect fan wiring connector first, then loosen all shroud fixing bolts
4. Replace whole fan assembly as one unit, align mounting clips and lock all bolts to factory torque standard
5. Reconnect wiring plug, confirm firm lock of connector waterproof buckle
6. Start vehicle, turn on air conditioning and observe fan automatic speed switching function
7. Road test under idle, medium speed and climbing conditions, monitor engine water temperature and AC cooling performance
8. Clear cooling system related fault codes with VCDS/ODIS VAG dedicated diagnostic scanner if needed
