A used genuine OEM Audi auxiliary radiator coolant hose, part number 4M0145920AC, sourced from a donor vehicle. This hose routes coolant through the auxiliary radiator to assist engine cooling in Audi Q7 models equipped with the 3.0L V6 engines—whether diesel, gas supercharged, or gas mild-hybrid turbocharged. A cracked or leaking auxiliary radiator coolant hose can cause visible coolant puddles, low coolant warnings, or engine overheating under load.
