The radiator and hose kit manages the flow of engine coolant between the engine and radiator to maintain optimal engine temperature. The radiator dissipates heat from the coolant, while the hoses carry coolant between the radiator and engine water jackets. Rubber isolators cushion and secure the radiator, reducing vibration and preventing wear from chassis movement.

This kit ensures your Macan’s engine stays within the correct operating temperature range under all driving conditions - from daily commutes to spirited driving. It replaces worn or brittle components with OE-match parts that deliver reliable heat transfer, proper coolant circulation, and secure mounting. This reduces the risk of overheating, pressure loss, and premature part failure.

Kit Components:
1x  9A712125101 - OE Match Radiator
1x  95B122101D - OE Match Coolant Hose – Upper
1x  95B121109E  - OE Match Coolant Hose – Lower
2x  8K0121276A - Genuine Radiator Rubber Isolator
2x  4H0121268A – Genuine Radiator Rubber Isolator
2x 8K0121275C –  Genuine Radiator Rubber Isolator 

Positioning:
•  Radiator - front of engine bay
•  Hoses - connect radiator to engine water pump and cylinder head outlets
•   Isolators - secure radiator in chassis mounts

Over time, overheating, vibration, heat cycling, and coolant contamination degrade radiators and hoses. Rubber isolators can harden or compress, letting the radiator shift and rub against the chassis. Replacing these with an OE-match kit restores the integrity and reliability of the cooling system - reducing the chance of coolant leaks, hot spots, engine damage or unexpected breakdowns.

Replace your radiator & coolant system components under these conditions:
•  Visible leaks around radiator or hoses
•  Overheating or erratic temperature gauge readings
•  Brittle, swollen, or cracked hoses
•  Corrosion or bent fins on radiator core
•  Frequent need to add coolant
•  Old age / scheduled cooling system service
•  After engine overheating events or radiator impact damage
