How to service the catalytic converter for 3.0L and 4.0L engines on Ford Ranger?

The first step when servicing the catalytic converter for 3.0L and 4.0L engines is to place the vehicle on a hoist with neutral gear engaged. Begin by removing first the bolts and nuts coupled with gasket from the catalytic converter to muffler and tailpipe assembly and then do the same for the exhaust Y-pipe flange to catalytic converter connection. Finally remove the catalytic converter itself. Install members of an exhaust system by beginning with front components and complete installation before applying any tightening force. Efficiently clean down the mating surfaces between the exhaust Y-pipe and catalytic converter before checking for damage to these areas and the studs. There should be a cleaning procedure for the catalytic converter mating section and the muffler and tailpipe assembly that excludes damage to any surfaces. Position the exhaust Y-pipe flange-to-catalytic converter flange gasket onto established catalytic converter studs. Insert the catalytic converter into the vehicle while preventing damage to all mating surfaces between exhaust Y-pipe, catalytic converter and muffler and tailpipe as well as the catalytic converter studs before adding exhaust Y-pipe-to-catalytic converter nuts. Put the gasket for the catalytic converter-to-muffler and tailpipe attachment in place before starting construction with the loose installation of its connecting hardware. Finally, align the exhaust system.

How to service the catalytic converter on a 4.0L engine on Ford Mustang?

You should start the 4.0L catalytic converter service by first placing the car into neutral mode before hoisting it and then standing up the muffler with a jackstand. You should disconnect the intermediate pipe from the catalytic converter assembly by removing the exhaust coupler then disposing it. All heated oxygen sensors (HO2S) must be disconnected along with catalyst monitor sensors from their wiring connectors before any repair work starts to prevent damage. First remove right-hand HO2S electrical connectors then disconnect left-hand HO2S electrical connectors followed by right-hand and left-hand catalyst monitor sensor electrical connectors. Tighten all hand-bolted catalytic converter nuts before taking off and discarding the two RH catalytic converter-to-exhaust manifold nuts. Install the new nuts by torquing them to 45 Nm (33 ft. lbs.) at 10 Nm (89 inch lbs.) intervals with the first application on the upper nut. Perform the same procedure on the two LH catalytic converter-to-exhaust manifold nuts. Avoid damaging the manifold outlet or converter inlet flares and their feeding studs when you uninstall the catalytic converter assembly. The mating surfaces of the manifold outlet flare and catalytic converter inlet flare and muffler inlet pipe need cleaning with Scotch Brite pad while preventing foreign materials from accessing the catalytic converters. To secure the positioning of the catalytic converter a jackstand should be used behind the outlet. The manifold studs should align with the pipe flange while hanger rods must be centered in the isolators. After finishing the installation follow the removal steps while using new converter-to-manifold nuts along with an exhaust coupler.
