This used OEM Mercedes-Benz coolant hose, genuine part number 1665003475, also known as a coolant line, carries engine coolant through the turbocharged V6 and V8 powertrains found in the GL, GLE, GLS, and ML classes. A common failure symptom on these hoses is cracking at the molded bends, leading to coolant seepage and potential overheating.
