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.

Product Information
Radiator water fan.
This radiator cooling fan is a direct-fit OE Match replacement part for older Porsche 911 996 and Porsche Boxster 986 models. Designed to OE dimensions and specifications for proper fitment and clearance. Restores cooling efficiency and A/C performance.
Sold each, 2 required per vehicle.

Fits:
Porsche 986 Boxster 1997 - 2004
Porsche 996 C2, C4, GT3 1998 - 2005

Diagram ref no 2.

The purpose of this radiator cooling fan is to draw air through the radiator and air conditioning condenser when the vehicle's speed is low - for example, when idling or in traffic - helping maintain the proper coolant and cooling system temperature. This keeps the engine cool and the air conditioning system operating efficiently.

•  Plug-and-play installation: fits directly into the original fan housing (left or right depending on configuration) without modification.

As cooling fans age, their motors and bearings can wear out, their brushes may degrade, or blade balance may shift. This reduces airflow, which in slow traffic or hot conditions can cause elevated engine or coolant temperatures, risking overheating or reduced A/C performance. A correct replacement fan ensures reliable cooling, protects the engine and maintains comfort and safety.

When to replace:
• Fan fails to activate when hot / radiator temperature rises
• Fan runs loudly, rattles or vibrates - indicating worn bearings or balance issues.
• Car overheats or A/C performance drops during low-speed driving or idle.
• Original fan removed or damaged during cooling-system maintenance (radiator, hoses, etc.).

About Water / Coolant Radiators

Water Coolant Radiators – Efficient Cooling Performance for Porsche Engines

Water coolant radiators are the heart of your Porsche’s cooling system, responsible for maintaining the perfect balance between performance and engine temperature. These components dissipate heat from the coolant as it passes through the radiator core, ensuring your engine operates at peak efficiency while preventing overheating - whether you’re cruising through city streets or pushing hard on the track.

At Design911, we offer a comprehensive range of genuine and high-quality water coolant radiators for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and transaxle cars. Each radiator is precision-engineered to provide efficient heat exchange, corrosion resistance, and a perfect fit, ensuring long-lasting performance and reliability for every driving condition.

What Do Water Coolant Radiators Do?

Radiators are essential to your Porsche’s engine cooling system. Their primary functions include:

  • Transferring heat from the coolant to the surrounding air.
  • Regulating coolant temperature to prevent engine overheating.
  • Supporting overall thermal balance for performance and emissions efficiency.
  • Enhancing reliability by maintaining optimal operating temperatures in all climates.

By efficiently dissipating heat, radiators protect your engine, prevent premature wear, and maintain consistent performance under pressure.

Why Do Radiators Fail?

Despite being built for endurance, radiators experience constant thermal stress, exposure to pressure, and environmental elements that can lead to failure. Common causes include:

  • Corrosion or rust due to contaminated or old coolant.
  • Leaks from cracked tanks, damaged cores, or failing seals.
  • Blockages caused by debris or scale build-up inside coolant passages.
  • Physical damage from road debris or stone impacts.
  • Coolant contamination from oil or combustion residue.

Symptoms of radiator failure include overheating, coolant loss, visible leaks, or fluctuating temperature readings.

Why Replace a Faulty Radiator?

A damaged or inefficient radiator compromises your Porsche’s cooling system, risking overheating and potential engine damage. Replacing your radiator with a high-quality, manufacturer-standard unit ensures optimal cooling efficiency, reliability, and peace of mind.

Benefits of replacement include:
Restored cooling efficiency and heat dissipation.
Prevention of engine overheating and coolant loss.
Enhanced vehicle performance and fuel economy.
Durable, corrosion-resistant materials for long service life.

All radiators in our range are designed using premium aluminium cores, precision welds, and reinforced end tanks to ensure excellent cooling capacity, leak prevention, and long-term reliability — perfect for both standard and high-performance Porsche applications.
