Information
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 >>
Diagram ref no 1
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

Information
Radiator / Engine cooling fan, 400 W, without carrier.
This radiator cooling fan is a direct-fit replacement for the factory 400 W electric fan used on Porsche 992 (992.1 series) models. Designed for precision cooling performance, this fan operates within the original geometry, connector layout, and mounting interface. It helps regulate engine temperature by drawing airflow through the radiator during low-speed or high-load conditions.
Fits:
Porsche 992.1 Carrera 2019>>
PLEASE NOTE: Radiator fan bracket has to be transferred over to new fan or sourced separately. Not included with this fan.
Porsche part number 992121435.
Diagram ref no 2
• Power: Rating 400 W
• Function: Draws air through the radiator to maintain optimal coolant and engine temperature
• Position: Front radiator section, left or right depending on configuration
• Symptoms of wear: Overheating at low speed, fan noise, intermittent operation
• Benefits: OEM-quality airflow and cooling, quiet and efficient motor, plug-and-play installation
• Installation: Direct-fit; reuse original fan carrier or shroud as required
Over time, radiator fans are exposed to heat, vibration, and moisture, which can cause gradual wear of the motor bearings, electrical windings, or blade balance. A weakened or failing cooling fan can no longer move enough air through the radiators, leading to higher operating temperatures — especially noticeable in traffic or hot weather.
Replace your cooling fan when you notice:
• Rising coolant temperature at idle or low speeds
• Intermittent or noisy fan operation (grinding or humming sounds)
• Fan not engaging even when the engine is hot
• Fault codes or warning messages related to cooling system performance.
It’s also good practice to install a new fan during radiator or condenser replacement, or whenever there’s evidence of electrical faults, motor burnout, or impact damage to the blades or shroud.
Replacing with an replacement restores consistent cooling performance, protects the engine from overheating, and ensures the fan system operates quietly and efficiently — just as Porsche intended.
