  Q: What steps should be followed when servicing the catalytic converter on Ford Freestyle?

  A:

  Service the catalytic converter during a cooldown period since its operating temperature near the catalytic converter reaches extremely high values. Replace the two upper catalytic converter-to-exhaust manifold bolts and gaskets that either service the front or rear unit by installing new gaskets which require 70 Nm (52 lb-ft) torque. Set the vehicle on a hoist at neutral gear position. The installation of front catalytic converter brackets requires unforgiving the bracket bolt followed by tightening to 40 Nm (30 lb-ft). Unplug the electrical connection of the catalyst monitor sensor. Remove and throw away both lower catalytic converter nuts before pulling out the front or rear catalytic converter. The catalytic converter installation process should include new gaskets along with alternative micronutrient applications to the catalyst converter nuts while maintaining exhaust system sealing and keeping exhaust flanges parallel until torque reaches 40 Nm (30 lb-ft). The front catalytic converter replacement requires checking the bracket clamp for replacement and installing proper torque at 40 Nm (30 lb-ft) on the clamp bolt. Prior to catalyst converter installation you need to apply anti-seize lubricant to the sensor threads before unscrewing the sensor and then tighten it to 47 Nm (35 lb-ft). Reverse the exhaust system removal procedure while using new gaskets and fasteners to clean the mating surfaces of the connections.

  Q: How to properly service a catalytic converter on Ford Freestyle?

  A:

  Service the catalytic converter only after the exhaust system has cooled to safety since the catalytic converter especially reaches high operating temperatures right after engine startup. Reassembling the exhaust requires new fasteners bearing the same part number as the originals because exhaust fasteners rely on torque prevailing design while following specified torque values will guarantee exhaust component retention. The front catalytic converter requires removal of the 2 upper converter-to-exhaust manifold bolts and gasket which should then be replaced by a new gasket before tightening to 40 Nm (30 ft. lbs.). The vehicle needs to be placed on a hoist in neutral position while technicians should also remove the bracket bolt during front catalytic converter removal and tighten the bolt to 40 Nm (30 ft. lbs.). Remove the sensor cable connector of the catalyst monitor followed by removing and discarding the two lower nuts holding the front or rear catalytic converter. A new gasket should be used during installation followed by alternating the catalytic converter nuts to keep the exhaust flanges parallel while final tightening to 40 Nm (30 ft. lbs.). Inspect the bracket clamp of the front catalytic converter for replacement while tightening the clamp bolt to 40 Nm (30 ft. lbs.). You should prepare the catalyst monitor sensor threads with anti-seize lubricant then remove the sensor while tightening it to 47 Nm (35 ft. lbs.). The installation process should begin with mating surface cleaning and follow all steps in reverse order to install new gaskets and exhaust fasteners.
