Additional center coolant radiator
The Porsche Genuine OE Additional Center Coolant Radiator (PAB145804) is a specific auxiliary cooling component designed to manage excess heat in hybrid-assisted Cayenne 9YA models. It enhances the ability of the cooling system to regulate coolant temperature during heavy engine load or hybrid system operation - contributing to efficient engine performance and longevity through improved thermal management.

Fits:
Porsche 9YA (E3) Cayenne 3.0L  / 4.0L Hybrid  2018 - 2024
Porsche 9YA.2 (E3 PA) Cayenne 3.0L Hybrid 2023 >>

This additional center coolant radiator functions as a supplementary heat exchanger in the engine’s cooling system. It helps dissipate excess heat from the engine coolant, reducing overall operating temperature and relieving load on the primary radiator - particularly under higher thermal loads seen in hybrid-assisted or high-performance operation. By improving coolant temperature control, it supports optimal combustion efficiency, long-term durability, and consistent engine performance.

Applications
•  Cooling system repair: Replace a damaged or failed auxiliary radiator component
•  Performance reliability: Add or restore cooling capacity to support hybrid engine thermal loads
•  Factory-standard restoration: Use when rebuilding or fully servicing cooling circuits
•  Preventative maintenance: Install as part of coolant system servicing for consistent temperature control

Fitment / Position on Car
•  Installed on: Engine bay, mounted centrally as part of the coolant heat-exchange system
•  Location: Integrated with front cooling network alongside main radiator cores and intercoolers
•  Connection: Works within the standard coolant piping and hose routing for the Cayenne 9YA hybrid platform

Modern performance and hybrid engines, such as those found in the Cayenne 9YA, generate additional heat due to electric motor assist, turbocharging, and high output demands. An auxiliary radiator increases total cooling surface area, helping prevent overheating, reduce thermal stress on primary components, and maintain consistent performance both in everyday driving and demanding conditions. Choosing a genuine Porsche OE cooling radiator means getting the exact specification, durability, and fitment that Porsche engineers designed for your vehicle’s thermal system

Additional center coolant radiator
This radiator is designed for direct-fit installation using existing mounting points and coolant hoses, without modification. It is ideal for replacement during cooling system servicing, radiator upgrades, or when a worn or damaged unit is affecting system performance.

Fits:

Diagram ref no 1

The additional centre coolant radiator increases the total heat rejection capacity of the cooling system. By providing supplementary heat dissipation ahead of or in conjunction with the main radiator, it helps:
• Maintain consistent operating temperatures under heavy load or high ambient heat
•  Improve thermal stability for engine and hybrid components
•  Reduce strain on the primary radiator and cooling fans
•  Support extended performance driving or high-duty cycles

An inefficient or failing additional radiator can reduce the cooling system’s ability to control engine temperature, leading to overheating, reduced performance, and increased stress on the main radiator. On hybrid models, inadequate thermal management can also impact electrified components. Replacing a compromised unit with an OE Match radiator restores correct cooling capacity and helps maintain performance, reliability, and long-term engine health.

When to replace:
•  Visible damage, bent fins, or leaks
•  Coolant stains or corrosion on the radiator cores
•  Overheating or rising temperature gauges
•  After front-end impact/collision damage
•  During complete cooling system overhaul

Constructed from high-quality aluminium with precision-engineered cooling fins and internal coolant passages, the radiator maximises heat transfer as coolant flows through the unit. Working in conjunction with the thermostat, cooling fans and water pump, it helps regulate engine temperature under all driving conditions, from everyday commuting to heavy-load and high-performance driving.  

What This Product Does:
  • Dissipates heat from the engine coolant.
  • Maintains correct engine operating temperature.
  • Prevents engine overheating.
  • Supports efficient coolant circulation throughout the cooling system.
  • Helps maintain optimum engine performance and fuel efficiency.
  • Protects critical engine components from heat-related damage.
  • Works with cooling fans, thermostat and water pump to regulate temperature.
  • Contributes to long-term engine reliability and durability.

Symptoms Of Wear Or Failure:
  • Engine overheating or elevated coolant temperatures.
  • Coolant leaks from the radiator core or end tanks.
  • Low coolant level warnings.
  • Visible corrosion or damage to the radiator fins.
  • Coolant pooling beneath the vehicle.
  • Reduced cooling system efficiency.
  • Frequent overheating during traffic or heavy-load driving.
  • Blocked or damaged cooling fins restricting airflow.
  • Sweet coolant odour from the engine bay.
  • Cooling system pressure loss.

Why Replacement Matters:

  • The radiator is continuously exposed to coolant flow, pressure fluctuations, road debris, moisture, corrosion and temperature extremes. Over time, internal passages can become restricted, cooling fins may become damaged and corrosion can weaken the radiator structure, reducing its ability to dissipate heat effectively.
  • A failing radiator can compromise cooling system performance, increasing the risk of engine overheating. Continued operation with inadequate cooling can lead to severe engine damage, including warped cylinder heads, damaged head gaskets and premature wear of internal engine components.
  • Replacing a worn or damaged radiator restores proper cooling system efficiency, helps maintain stable operating temperatures and protects the engine from costly overheating-related damage. A genuine Porsche replacement ensures factory-correct fitment, optimal heat dissipation and long-term reliability, helping preserve the performance, efficiency and durability expected from your Porsche.

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.
