Audi heater coolant hose, part number 4F1819372 — a used OEM line pulled from a genuine donor vehicle. This hose carries hot coolant from the engine to the heater core; when it cracks or develops a leak, you'll notice coolant loss, a sweet smell in the cabin, or poor cabin heat. Also called a heater coolant line, it was fitted to naturally aspirated and supercharged V6 and V8 engines in the Audi A6, A6 Quattro, and S6. No additional part numbers are on record for this piece.
