- Description:
Main, #3. Alternator. This genuine Audi Radiator Coolant Hose, part number 4K0-121-062-F, moves heat out of the engine and charge air circuits, and because modern Audi engines run tight thermal windows, a partial loss of cooling capacity shows up as performance and economy loss before it shows as overheating. Genuine Audi tooling and materials mean it installs into the original mounting points without modification. Check the applications list or supply your VIN to confirm this part fits your vehicle.

Key Product Information
Additional Information
| SYMPTOMS | Before ordering 4K0-121-062-F, look for these indicators: rising coolant temperature, low coolant level warnings, sweet smelling steam, a heater that blows cold, or visible pink or clear residue on hoses and joints. Noting which conditions are present shortens diagnosis considerably at the shop. |
| TROUBLESHOOTING | Verify the fault before ordering 4K0-121-062-F: pressure test the system cold to expose seeping joints, then verify thermostat opening behavior against live coolant temperature data before replacing pumps or radiators. If the fault is intermittent, check wiring and connectors before the component itself. |
| INSTALLATION | Correct installation of this radiator and cooler (4K0-121-062-F) calls for a proper vacuum or bleed fill so no air pocket remains, since trapped air in these systems causes false overheating and heater performance complaints. Confirm correct operation and scan for stored faults before returning the vehicle to service. |
| MAINTENANCE | Long term care of this radiator and cooler (4K0-121-062-F) means using the correct Audi coolant specification, never mixing coolant types, and checking hose condition and clamp tension at each service. Use fluids and parts that meet the Audi specification for the vehicle. |
| GENERAL_NOTES | Ordering note for 4K0-121-062-F: coolant color and specification vary by production era, and mixing incompatible types causes gelling that clogs the heater core and radiator. This is a genuine Audi part supplied through the factory parts network. |
| REPLACEMENTS | Commonly replaced alongside 4K0-121-062-F: hose clamps, O-rings, thermostat housings, and coolant are renewed at the same time because access is shared and old seals rarely reseal. Ask for the related hardware when ordering so the job is completed in one visit. |
