Catalytic Converter



Removal & Installation
4.0L Engine
Specific to:
Ford Mustang 2009-2010
  1. With the vehicle in NEUTRAL, position it on a hoist.
  2. Using a jackstand, support the muffler.
  3. Loosen the exhaust coupler and disconnect the intermediate pipe from the catalytic converter assembly. Discard the exhaust coupler. To install, tighten to 35 ft. lbs. (48 Nm). Alternately tighten, in 89 inch lbs. (10 Nm) increments.
    NOTE
    When repairing the exhaust system or removing exhaust components, disconnect all Heated Oxygen Sensor (HO2S) and Catalyst Monitor Sensor (CMS) at the wiring connectors to prevent damage to the sensors and wiring harnesses.
  4. Disconnect the RH and LH Heated Oxygen Sensor (HO2S) electrical connectors.

    NOTE
    Using a jackstand, support the catalytic converter near the rear outlet while positioning the converter into place. Align the manifold studs into the pipe flange. Make sure not to damage the studs or mating surfaces.
  11. Make sure to correctly align the catalytic converter to the exhaust manifold before installing the fasteners. The catalytic converter is correctly positioned when the hanger rods are centered in the isolators.
