REMOVAL AND INSTALLATION

Water Temperature Indicator Sender Unit, Gasoline Engines

Removal

  1.  CAUTION: Do not remove the radiator cap (8100) on a hot engine.

    Remove radiator cap to relieve any pressure and then replace radiator cap. This reduces coolant loss during sender replacement.

  1. Disconnect the temperature sending unit wire at the sending unit.

Installation

  1. Prepare the new temperature sending unit for installation by applying the Pipe Sealant with Teflon® D8AZ-19554-A or equivalent meeting Ford specification WSK-M2G350-A2, or a small amount of electrically conductive sealer to the threads.

  1. Remove the temperature sending unit from cylinder head (6049) and immediately install the new temperature sending unit. Tighten to 11-24 Nm (8-18 lb-ft).

  1. Connect the wire to the temperature sending unit.

  1. Refill cooling system to replace lost coolant.

  1. Start the engine and check the sending unit operation.
