- Description:
This is a Genuine Ford engine coolant thermostat carrying Ford part number HL3Z-8575-B. The thermostat fits 17-22 F-150 trucks equipped with the 3.5L EcoBoost twin-turbo V6, along with the related Expedition and Lincoln Navigator full-size SUV applications using the same engine through the early 22 service window, with a starting service window in late 16 for this configuration. This part supersedes the earlier HL3Z-8575-A. The thermostat is the primary engine warm-up control device and regulates coolant flow between the engine and radiator to maintain target operating temperature. On the EcoBoost engines, thermostat performance is critical because turbocharger durability and emissions control depend on stable coolant temperature. The thermostat is sometimes included with the complete thermostat housing assembly and is also available as a standalone replacement. Genuine Ford thermostats use the OEM specification opening temperature and flow characteristics required by the EcoBoost calibration. This part ships in original Ford OEM packaging. Installation should follow the published Ford workshop procedure with attention to correct orientation in the housing, proper sealing of associated O-rings or gaskets, and a complete cooling system bleed after refill.
- Notes: Included with thermostat housing.
- Applications: 3.5L.
