Radiator for water coolant fluid. Porsche 971 Panamera 2017-23 / 976 Panamera 2023>>  ❭  PAE121253

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.

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.
