How to service and repair the catalytic converter on Mercury Cougar?

The first step to repair the three-way catalytic converter (TWC) is to remove its heat shield followed by disconnecting TWC from the manifold. Take the necessary measures to lift and stabilize the vehicle before unclipping the heated oxygen sensor electrical wiring connector. The service begins with separating the hanger insulator from the flange connection. Proceed to remove both the flexible pipe assembly along with the TWC by first untightening the nuts followed by nut and bolt removal. Begin with TWC and flexible pipe assembly placement before installing the nut and bolt and finally tightening the bolts. Check the hanger insulators for wear and replace damaged parts then treat all hanger insulators with Myrpol Lubricant D7AZ-I9553-AA or an equivalent solution that adheres to Ford standard ESEM99B 144-B. Apply a new gasket and fasten nuts loosely before securing the flange connection. Lower the vehicle while avoiding the application of jointing compound anywhere ahead of the catalytic converter before tightening the nuts. First raise and support the vehicle before reinstalling the heat shield and following with delivering a snug torque on the nuts and attaching the heated oxygen sensor electrical connector with proper wiring position maintenance.
