2007 Lincoln MKZ Catalytic Converter Parts Questions & Experts Answers

• Q: How to service the catalytic converter on the 3.5L RH manifold on 2007 Lincoln MKZ?

  A: Start the catalytic converter service of the 3.5L RH manifold by placing the vehicle in NEUTRAL position and mounting it on a hoist. Begin by removing the exhaust Y-pipe before extracting 2 bolts that fasten the power steering rack shield, and when reinstalling tighten the bolts to 15 Nm (11 ft. lbs.). You should take out the roll restrictor bolt then rotate the engine forward before torquing it to 90 Nm (66 ft. lbs.) when putting it back in. You must first detach the CMS catalyst monitor sensor electrical connector then take out the two support bracket nuts attached to the engine block using 40 Nm of torque (30 ft.lbs.) for reinstallation. The 4 RH catalytic converter nuts must be removed along with the establishment of new nuts and gasket disposal. It is essential to tighten both new nuts and gasket at 40 Nm (30 ft. lbs.) during reinstallation. Separate the 4 RH catalytic converter-to-exhaust manifold studs before installation of new components which should be torqued to 25 Nm (18 ft. lbs.). Proceed with the reversal of steps by placing new gasket and nuts while performing the installation.
