This used genuine OEM lower coolant reservoir hose, OEM part number 1K0121109AH, routes coolant between the expansion tank and engine on Audi A3 Quattro and VW Eos/R32 models. Also known as a coolant reservoir line, it’s designed for the 3.2L V6 (both 3189cc and 3197cc variants). Over time, the plastic or rubber can crack, causing coolant loss and potential overheating. Replacing it restores proper circulation and prevents air pockets.
