Radiator for water coolant fluid.
Radiator for water coolant fluid (also known as Coolant radiator, Water radiator or Water coolant fluid cooler) is the backbone of a Porsche engine’s thermal management system. It dissipates heat from the engine’s water-based coolant, stabilising engine temperatures, preserving performance, efficiency, and long-term reliability.

Fits:
Porsche 987 Boxster - 2005 to 2012
Porsche 987C Cayman - 2005 to 2012
Porsche 997 - 2005 to 2012

The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.

Proper heat rejection helps:
•  Maintain optimal engine operating temperature
•  Prevent overheating under everyday and high-load conditions
•  Support fuel efficiency and emission control
•  Preserve engine component durability and longevity

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.

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:
