The used OEM Audi heater coolant hose, part number 80B819373B, carries hot coolant to the cabin heater core. Removed from a 2.0L TFSI turbocharged Audi Q5, this genuine hose replaces compromised rubber that can crack and leak, leading to coolant loss, engine overheating, or no heat. Also called a coolant line or heater hose, it is a direct-fit replacement for the donor engine family.
