Please note: Before ordering, please check the part number in the vehicle.

It’s ideal as a cost-effective replacement when the factory fan has become noisy, weak, or failed completely.

Function:
• Draws air through the radiator and condenser to assist engine cooling
• Supports stable coolant temperatures at idle, low speeds and high load
• Integrates with the vehicle’s fan control strategy for staged or variable-speed operation.

Over time, cooling fans are subjected to heat, vibration and moisture, which can wear motor bearings, damage windings or throw the fan out of balance. A weak or failing fan can’t move enough air, causing rising coolant temperatures, especially in slow traffic or on hot days. Replacing it with a properly spec’d OE-Match unit restores consistent cooling performance and helps protect the engine from overheating.

When to Replace:
• Coolant temperature climbs at idle or in traffic
• Fan runs noisily (grinding, humming or excessive vibration)
• Fan fails to start even when the engine is hot
• Intermittent fan operation or related fault codes
• Radiator/condenser replacement where the old fan shows wear or damage.

Diagram ref no 1

The CR89000P offers a high-quality replacement solution for a leaking, damaged, corroded or blocked original centre radiator.

Located at the front centre of the vehicle, this radiator forms an important part of the Porsche engine cooling circuit. Coolant heated by the engine flows through the radiator core, where heat is transferred to the surrounding airflow before the cooled fluid returns through the system.

Maintaining an efficient radiator is especially important on high-performance Turbo, GT3, GT3 RS, GT2 RS, Spyder and GT4 models, where the cooling system must manage considerable thermal loads during demanding road or track use.

Why Replace a Coolant Radiator?

Radiators are exposed to road debris, moisture, dirt and repeated heating and cooling cycles.

Over time, deterioration can result in:

Coolant leaks
Damaged or corroded cooling fins
Blocked airflow
Internal restriction
Damaged plastic end tanks
Reduced cooling efficiency
Rising coolant temperatures
Coolant loss
Engine overheating

The centre radiator is positioned at the front of the vehicle and can also accumulate leaves, dirt and debris between the cooling surfaces, which can reduce airflow and accelerate corrosion.

MAHLE Cooling Technology
MAHLE is a major specialist in engine thermal-management and cooling components.

The CR89000P uses a brazed radiator core engineered to transfer heat efficiently from the engine coolant to the airflow passing through the radiator.

The combination of closely spaced cooling fins and internal coolant channels provides a large heat-transfer surface within a compact package.

This makes it a suitable stock-style replacement for the demanding cooling requirements of Porsche Turbo and GT models.

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.

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.
