VW Polo 9N, SEAT Ibiza 6L & Audi A1 8X Heater Core 6Q0819031 6RD819031

Product overview

This aluminium brazed heater core, also described as a warm air heat exchanger, is a replacement part for the VW Polo 9N, SEAT Ibiza III, SEAT Cordoba and Audi A1. It sits inside the heating and ventilation housing and transfers engine coolant heat to the cabin, so a blocked or leaking core often shows up as poor heater output, a sweet smell or misting windows.

Replacing a tired heater core restores cabin warmth and demisting performance, which matters on cold winter mornings. It is also worth flushing the cooling system at the same time, as old coolant and debris are a common cause of heater core blockages.
