The radiator fan is a critical part of a water-cooled engine's thermal management system. While airflow through the radiator naturally increases when the vehicle is moving, additional forced airflow is required when driving slowly, sitting in traffic or operating under conditions where natural airflow is insufficient. The electric fan draws or pushes air through the radiator as required, allowing heat to be transferred from the engine coolant to the surrounding air.

A worn or failed radiator fan can significantly reduce cooling efficiency, particularly at low road speeds. Problems can develop through motor wear, damaged fan blades, worn bearings, electrical faults or physical damage to the assembly.

This OE Match 400W, 370mm Radiator Water Fan provides a high-quality replacement for a defective original unit, helping restore controlled coolant temperatures and reliable cooling-system performance.

What This Product Does:

• Provides forced airflow through the radiator.
• Uses a 400W electric motor.
• Features a 370mm fan diameter.
• Helps remove heat from the engine coolant.
• Supports correct engine operating temperature.
• Provides additional cooling when vehicle speed is low.
• Helps maintain cooling performance when stationary in traffic.
• Supports cooling during demanding operating conditions.
• Works with the vehicle's cooling-system controls and temperature management strategy.
• Helps reduce the risk of overheating caused by inadequate radiator airflow.
• Replaces a worn, noisy, damaged or failed radiator fan.
• Provides an OE-style replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Engine temperature rising when stationary or in slow-moving traffic.
• Cooling performance improving once vehicle speed increases.
• Engine temperature becoming higher than normal.
• Radiator fan failing to operate when required.
• Fan operating intermittently.
• Fan rotating more slowly than expected.
• Unusual grinding, scraping or rattling noises.
• Excessive vibration from the fan assembly.
• Squealing or bearing noise from the fan motor.
• Damaged, cracked or broken fan blades.
• Fan blades contacting the surrounding housing or shroud.
• Fan motor overheating or failing electrically.
• Cooling-system or fan-related warning messages.
• Diagnostic fault codes relating to cooling fan operation.  

Why Replacement Matters:

• Maintaining the correct engine operating temperature is essential for performance, reliability and engine longevity. The radiator can only dissipate heat effectively when sufficient air passes through its cooling fins.
• At motorway speeds, vehicle movement generally provides substantial airflow. At idle or in slow traffic, however, the electric radiator fan becomes much more important. If the fan is unable to operate correctly, coolant temperature can rise rapidly despite the rest of the cooling system being functional.
• Repeated or severe overheating can have serious consequences. Excessive temperature can damage seals and gaskets, accelerate deterioration of cooling-system components and, in extreme circumstances, contribute to cylinder-head or engine damage.
• A damaged fan blade or worn motor bearing should also be addressed promptly. Excessive vibration can place additional stress on the fan assembly and surrounding components, while a damaged blade may eventually contact the shroud or fail completely.
• Replacing a defective unit with this OE Match Radiator Water Fan helps restore reliable radiator airflow, stable coolant temperatures and dependable engine cooling.
