Your vehicle's power steering supplements the steering system with hydraulic pressure. The Ford Focus, as well as every other car with hydraulic power steering, uses a pump to create the pressure that assists with steering. The basic steps to remove this pump are similar to the steps to remove any hydraulic pump. Some parts will have to be removed for access to the pump. Be aware that there are slight variations to the process depending on the exact model.

    Remove the hydraulic fittings from the old power steering pump and install them on the new pump.

  3. 3

    Install the power steering pump pulley on the new pump. You may have to do this after the pump is installed if the pulley was removed while the pump was still in the vehicle.

  1. 1

    Place the power steering pump into position and install the four mounting bolts. Torque them to 18 foot-pounds.

  2. 2

    Moisten a new O-ring with power steering fluid and install it on the power steering pressure line.

  3. 3

    Connect the power steering pressure line and torque the nut to 48 foot-pounds. Install the power steering line bracket and mounting nuts.

  4. 4

    Install the power steering supply house and secure its clamp.

  5. 5

    Connect the power steering pressure switch electrical connector.

  6. 6

    Rotate the accessory drive belt tensioner and install the drive belt around the power steering pump pulley. Slowly release the tensioner.

    Reinstall the splash guard and its mounting bolts.

  8. 8

    Lower the vehicle and reconnect the negative battery cable.
