Product Information

Radiator Water Coolant Fluid.
The Radiator / Coolant Cooler is designed to regulate engine temperature in Panamera 971 models. Acting as the primary heat exchanger, the radiator dissipates heat from the engine coolant to ensure optimal operating temperature, preventing overheating and protecting vital engine components.

Fits:

Porsche Panamera V6 3.0L 2017>>2021
Porsche Panamera 4 V6 3.0L 2017>>2021
Porsche Panamera 4 V6 3.0L 2017>>2021

What This Product Does / How It Works:
The radiator acts as a heat exchanger: hot coolant from the engine flows into it, the radiator transfers heat from the coolant to the ambient air (often with the help of cooling fans), then cooled coolant returns to the engine. This regulates engine temperature and prevents overheating.

Common Symptoms Of A Failing / Defective Radiator:

Overheating engine, especially under load or in hot weather.
Coolant loss (visible leaks under the car or in the engine bay).
Coolant discoloration or contamination (rust, debris) inside the cooling system.
Critical temperature warning light on the dash.
Reduced heater performance (in cold ambient temps) since system under pressure / impaired flow.
Steam or visible smoke from under the bonnet (if coolant is boiling or leaking).

Why Replacement Matters:

Engine Health & Longevity: Overheating can warp heads, damage gaskets, degrade oil, and cause other serious damage.
Performance & Efficiency: Cooler intake and engine components help maintain consistent power output, fuel economy, and smoother running.
Preventative Maintenance: Replacing before catastrophic failure (burst, crack, severe leak) avoids breakdowns and higher repair costs.
