- Description:
Audi part number 420-805-157-C, the factory Radiator Support Panel Reinforcement, 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. As a genuine Audi part it carries factory part numbering, original fitment data, and Audi parts warranty coverage. Confirm fitment against your vehicle identification number before ordering.
- Notes: Included with front inner structure.

Key Product Information
Additional Information
| SYMPTOMS | Common complaints that lead to 420-805-157-C being replaced: 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. Any of these conditions is worth diagnosing before it affects surrounding components. |
| TROUBLESHOOTING | To confirm 420-805-157-C is the cause rather than a symptom: pressure test the system cold to expose seeping joints, then verify thermostat opening behavior against live coolant temperature data before replacing pumps or radiators. Record any stored fault codes before clearing them. |
| INSTALLATION | Proper fitment of this radiator and cooler (420-805-157-C) 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. Compare the replacement against the original component before final assembly. |
| MAINTENANCE | Keeping 420-805-157-C in service means using the correct Audi coolant specification, never mixing coolant types, and checking hose condition and clamp tension at each service. Consistent service intervals matter more than mileage alone on this system. |
| GENERAL_NOTES | Ordering note for 420-805-157-C: coolant color and specification vary by production era, and mixing incompatible types causes gelling that clogs the heater core and radiator. Availability and part number supersession can change, so confirm the current number when ordering. |
| REPLACEMENTS | Related parts to order with 420-805-157-C: hose clamps, O-rings, thermostat housings, and coolant are renewed at the same time because access is shared and old seals rarely reseal. Most of the labor here is access, so replacing adjacent wear items now costs very little extra. |
