Detailed Description

Motorad Thermostat Assembly TA5129 is an engine coolant thermostat housing assembly built to match OEM specifications and safety standards. The copper case and wax compound are designed for quick reaction to coolant temperature changes, while the mechanical actuator and disk valve support consistent thermostat operation. This assembly is listed with gasket or seal included and a pre-installed seal, which helps streamline replacement on compatible Ford F-150, Ford Expedition, and Lincoln Navigator cooling systems.

Thermostat Assembly is a product line focused on complete thermostat service components rather than a bare thermostat alone. For buyers searching for a Ford F-150 thermostat housing assembly, Ford Expedition upper thermostat housing, or Lincoln Navigator coolant thermostat housing assembly, TA5129 provides a direct service-style solution with the housing and sealing elements integrated into one unit.

What It Is Used For

  • Replacing a leaking or damaged thermostat housing assembly.
  • Restoring proper coolant flow control after thermostat wear.
  • Addressing temperature fluctuation caused by a slow-reacting thermostat.
  • Repairing seal-related coolant seepage at the housing interface.
  • Servicing cooling systems that require a complete housing and seal assembly.
