• Description:

  This is a Genuine Ford turbocharger coolant line, identified as the Water Inlet Tube Right, carrying Ford part number HL3Z-8A520-B. The tube fits 17-21 F-150 trucks along with related Expedition and Lincoln Navigator applications equipped with the 3.5L EcoBoost twin-turbo V6, covering the 14th generation 17-20 trucks. The tube delivers coolant into the right bank turbocharger center housing as part of the turbo cooling circuit. Continuous coolant flow at this location is critical to bearing cartridge life, particularly during the after-shutdown soak period when residual heat from the turbine housing can otherwise drive oil coking at the bearing. This part number supersedes the earlier HL3Z-8A520-DD reference. The tube is shaped to the OEM routing required by the engine bay layout and uses OEM specification fittings and seals at each end. Substituting non-OEM tubes at this location is a common source of nuisance leaks because alternate routings can stress the fittings or contact the turbocharger heat shield. This part ships in original Ford OEM packaging. Installation should be performed during turbocharger or cooling system service with replacement of any associated O-rings, and the cooling system should be refilled and bled per the Ford procedure.
