Radiator Water Fan, Right.

The OE Match Radiator Water Fan is a replacement right-hand electric cooling fan for selected Porsche 987 Boxster, Cayman and 997 models.

Fits:

• Porsche 987 Boxster 2005>>
• Porsche 987C Cayman 2005>>
• Porsche 997 2005-08

Diagram Ref No 2

Mounted at the front of the vehicle behind the right-hand coolant radiator, the fan draws air through the radiator whenever natural airflow created by vehicle movement is insufficient.

This is particularly important when the vehicle is:

Idling.

Moving slowly.

Sitting in traffic.

Operating in hot weather.

Running the air-conditioning system.

Recovering from sustained high-load driving.

Porsche's water-cooled engines depend on continuous circulation of coolant through the front-mounted radiators. At normal road speed, forward movement provides substantial airflow through the radiator cores. When road speed falls, however, the electric cooling fans must provide the airflow needed to remove heat from the coolant.

A worn or failed right-hand fan can therefore allow engine temperature to rise during low-speed driving even though the cooling system may appear normal at higher speeds.

Replacing a defective fan helps restore correct airflow through the right-hand radiator and supports stable engine temperature, air-conditioning performance and overall cooling-system reliability.

What This Product Does:
The right-hand radiator fan moves ambient air through the right-side coolant radiator.

Its main functions are to:

• Draw cooling air through the radiator.
• Maintain coolant temperature at low road speeds.
• Provide cooling while the vehicle is stationary.
• Supplement natural airflow.
• Help prevent overheating in traffic.
• Support the cooling system during hot-weather operation.
• Assist cooling when air-conditioning demand is high.
• Work together with the opposite-side cooling fan.
• Maintain reliable engine cooling under changing operating conditions.

Symptoms Of Wear Or Failure:
Possible symptoms include:

• Engine temperature rising in slow traffic.
• Temperature normal at speed but increasing at idle.
• Right-hand fan not operating.
• One cooling fan running while the other remains stationary.
• Intermittent fan operation.
• Fan running slowly.
• Grinding or rumbling noises.
• Squealing.
• Excessive vibration.
• Fan blades wobbling.
• Fan stopping after becoming hot.
• Electrical burning smell.
• Blown fuse.
• Overheated electrical connector.
• Air-conditioning performance becoming poor while stationary.
• Engine overheating during low-speed driving.

Why Replacement Matters:
Replacing a worn or failed Radiator Water Fan helps restore:

• Correct radiator airflow.
• Stable coolant temperature.
• Reliable low-speed cooling.
• Balanced left/right radiator airflow.
• Reduced overheating risk.
• Correct cooling performance in traffic.
• Proper electrical fan operation.
• Reliable air-conditioning heat-exchanger airflow.

Diagram Ref No 11

Constructed from durable, heat-resistant rubber compounds, the mounting isolator is engineered to withstand continuous exposure to engine bay temperatures, moisture, vibration and environmental contaminants. It plays an important role in maintaining smooth radiator fan operation and preserving the integrity of the cooling system.  

What This Product Does:

• Secures the radiator fan assembly in its correct position.
• Absorbs and isolates vibration generated by the cooling fan.
• Reduces noise transmitted through the cooling system.
• Helps prevent excessive movement of the fan assembly.
• Protects mounting points from wear and fatigue.
• Reduces stress on surrounding cooling system components.
• Supports smooth and reliable radiator fan operation.

Symptoms Of Wear Or Failure:

• Excessive vibration from the radiator fan assembly.
• Rattling or knocking noises from the cooling fan area.
• Visible cracking, splitting or deterioration of the rubber mount.
• Loose or misaligned radiator fan assembly.
• Increased noise during cooling fan operation.
• Excessive movement of the fan shroud or mounting assembly.
• Premature wear of fan mounting points.
• Damage to surrounding cooling system components caused by vibration.

Why Replacement Matters:

• Rubber mounting isolators are continuously exposed to heat, vibration, moisture and environmental ageing. Over time, the rubber can harden, crack, compress or deteriorate, reducing its ability to absorb vibration and securely support the radiator fan assembly.
• A worn isolator can allow excessive fan movement and vibration, potentially leading to increased noise, mounting damage and additional stress on the cooling system. If left unresolved, vibration-related wear may contribute to premature failure of the fan assembly, mounting hardware or nearby components.
• Replacing a worn radiator fan isolator restores proper fan support, reduces vibration and helps maintain smooth cooling system operation. An OE Match replacement provides factory-style fitment, reliable vibration damping and long-term durability, helping protect your Porsche cooling system while ensuring quiet and efficient radiator fan performance.
