Audi A4 B5 / A6 C5 / VW Passat B5.5 1.8T & 2.8 Radiator 8D0121251P

Product overview

A replacement engine radiator referenced to OE number 8D0 121 251 P (8D0 121 251 Q is also quoted in the listing title). It suits B5-platform Audi and Volkswagen models with 1.8 T and 2.8 litre petrol engines and is offered in two core construction types.

Many of these vehicles are now well over twenty years old, and original radiators often suffer from brittle plastic tanks, internal blockage or external corrosion. A new radiator restores cooling efficiency and reduces the risk of overheating.

Technical specifications

Installation requirements

Allow the engine to cool before draining the coolant. These models usually require the front panel to be moved into service position for radiator access, so workshop fitting is recommended. Refill with the correct coolant, bleed the system and inspect hoses and clips while everything is apart.

Fitment checks before ordering

The part listing also mentions a condenser and water tank, so please confirm you need the engine radiator. Manual and automatic models may require different radiators. Compare your existing part number and verify by VIN before purchase. If you are unsure, send us your VIN and a photo of the radiator label, and we will help confirm the correct part before you order.
