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 for water coolant fluid
This radiator functions as the primary heat exchanger in the Porsche Panamera’s cooling system. It transfers heat from the hot engine coolant into the surrounding air, helping maintain stable engine operating temperatures. Efficient cooling supports power delivery, emission control, and engine longevity - especially under everyday driving and high-load conditions. A properly functioning radiator also reduces the risk of overheating, prevents needless stress on engine components, and contributes to consistent performance.
Fits:
Porsche 971.1 Panamera 2017 - 2020 with 'S' equipment (PR: A8F)
Porsche 971.1 Panamera 2017 - 2020 with 'turbo' equipment (PR: A8H)
Porsche 971.1 Panamera 2017 - 2020 Hybrid (PR:0K3) with 'Standard' equipment (PR:A8C)
Porsche 971.2 Panamera 2021 - 2023
Porsche 976 Panamera 2023 >>
Diagram Ref No 1
The radiator is the heart of the engine’s liquid cooling system, responsible for removing heat from the engine coolant before it returns to the engine. As hot coolant flows through the radiator’s core, heat is transferred to the air passing through the cooling fins, helping maintain ideal engine operating temperatures. Proper cooling prevents overheating, supports consistent performance, protects internal engine components from heat stress, and helps maintain fuel efficiency and emission control.
