OE Match coolant radiator.
Fits
Porsche 971.1 Panamera 3.0L 2017 - 2021
* with 'Standard' equipment (option code: A8C)
* without alternative drive system (option code: 0K0)
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
Heated coolant passes through the radiator, where its heat is released into the surrounding airflow. The cooled fluid then circulates back through the engine. Cooling fans assist airflow when needed, while the radiator forms part of the system that controls operating temperature.
Functions
- Releases heat carried by circulating coolant.
- Helps control engine operating temperature.
- Returns cooled fluid to the engine cooling circuit.
Technical Details
- Product type: engine coolant radiator / coolant cooler.
- Brand: OE Match.
- Supplied reference numbers: 9A712125310 and PAE121253A.
- Application requirements: equipment code A8C and drive-system code 0K0.
Symptoms of Fault
- Temperature climbing during demanding driving or warm weather.
- Falling coolant level, damp radiator surfaces or puddles beneath the vehicle.
- Sweet odour or dried deposits near radiator seams.
- Discoloured coolant containing corrosion residue or debris.
- Dashboard warning indicating excessive engine temperature.
- Weak cabin heating when coolant is low or circulation is impaired.
- Steam beneath the bonnet associated with escaping or boiling coolant.
- Damaged fins, visible corrosion or gurgling following shutdown.
Why Replacement Matters
Leaks and restricted coolant passages can reduce the radiator's ability to remove heat. Prolonged overheating may damage cylinder heads and gaskets, affect engine oil and lead to further repairs. Renewing a radiator with confirmed damage addresses the faulty component rather than repeatedly topping up lost coolant.
Inspect nearby hoses, joints, seals and mounting hardware during the repair. Similar symptoms can arise elsewhere in the cooling circuit, so establish the source before replacing parts.
FAQs
How can a radiator leak be distinguished from a hose leak?
Look for moisture or deposits on the radiator core and seams, then inspect hose connections. A cooling-system pressure test can help locate the source.
Can overheating occur without a visible leak?
Yes. Deposits inside coolant passages can restrict circulation without producing external seepage. Fan operation and thermostat behaviour also need checking.
What else should be inspected during replacement?
Check the pressure cap, thermostat, hoses and connections. Renew supporting components where inspection identifies deterioration rather than assuming every item needs replacement.

What This Product Does
The fan supports airflow through the coolant radiator, helping the cooling system disperse heat when airflow from vehicle movement is limited. This assembly includes the fan cowling; it is not a replacement radiator core.
Technical Details
- Brand: NRF.
- Supplied product reference: PAE121203A.
- Assembly: radiator cooling fan with cowling.
Symptoms of Fault
Increasing coolant temperature during slow-moving traffic or repeated overheating warrants investigation of the cooling system. These symptoms do not establish a fan fault: radiator obstruction, thermostat or pump problems, trapped air and coolant leaks can also contribute.
Why Replacement Matters
Renewing a confirmed faulty fan assembly helps restore the airflow needed for temperature control. Inspect the surrounding cooling components and remove accumulated debris rather than assuming that changing the fan alone will resolve every overheating concern.
FAQs
Should hoses and caps also be renewed?
Inspect older hoses and the coolant cap, replacing them if their condition requires it.
Does fan replacement require a coolant flush?
A fan fault alone does not establish the need for flushing. Assess coolant condition separately, particularly where contamination or mixed coolant history is suspected.
What else should be inspected?
Check for debris obstructing the radiator and condenser, and investigate any coolant loss or evidence of leakage.
