Manufactured to OE specifications for fit, function and reliability, this 2-pin temperature switch helps maintain correct engine operating temperatures, protects against overheating and ensures efficient cooling system performance. It is an essential replacement item for maintaining the reliability of the vehicle's cooling system.
What This Product Does:
- Monitors coolant temperature within the cooling system.
- Activates the electric radiator cooling fan when required.
- Helps maintain optimum engine operating temperature.
- Prevents excessive heat build-up during low-speed driving or idling.
- Supports efficient cooling system operation.
- Protects the engine from overheating-related damage.
Symptoms Of Wear Or Failure:
- Cooling fan fails to operate when the engine reaches operating temperature.
- Engine temperature rises higher than normal.
- Engine overheating during traffic or idle conditions.
- Cooling fan runs continuously regardless of temperature.
- Inconsistent cooling fan operation.
- Temperature warning light activation.
- Reduced cooling system efficiency.
- Overheating during warm weather or heavy traffic conditions.
Why Replacement Matters:
- The fan temperature switch plays a critical role in controlling cooling fan operation and maintaining stable engine temperatures. Over time, repeated heat cycles, age and electrical wear can affect the switch's ability to accurately detect coolant temperature and activate the fan.
- A failed switch can prevent the cooling fan from operating when needed, significantly increasing the risk of overheating. Excessive engine temperatures can damage gaskets, seals, cooling system components and, in severe cases, major engine components.

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
