Auxiliary coolant / water pump hose from a used Audi TT—genuine OEM part number 8N0121063. This hose connects the auxiliary water pump to the cooling system on the 1.8T (1781cc turbocharged four-cylinder) engine. When it cracks or leaks, it causes coolant loss and potential overheating. Also referred to as the auxiliary coolant hose or auxiliary water pump hose, this original-equipment piece ensures proper circulation through the secondary pump.
