Diagram Ref No 1

The water/coolant radiator serves as the cooling system’s primary heat exchanger, where hot coolant from the engine is cooled by airflow before being circulated back into the engine. This process helps:
•  Maintain stable engine temperature
•  Prevent overheating under load
•  Improve heater and climate control performance
•  Protect engine components from thermal stress
•  Support efficient combustion and emissions control

A failing radiator can lead to engine overheating, coolant loss, performance penalties, and - in extreme cases - engine damage. Symptoms of radiator issues include rising temperature gauge readings, coolant leaks under the vehicle, reduced heater output, and visible core damage. Replacing an inefficient or damaged radiator with an OE Match unit restores effective cooling capability and helps maintain the Porsche Panamera’s performance and drivetrain health.

When to replace:
•  Persistent engine overheating or temperature spikes
•  Visible radiator leaks, punctures, or core corrosion
•  Bent, clogged, or damaged cooling fins
•  After front-end impact or collision
•  During cooling system overhaul (water pump, thermostat, hoses)
