How to Remove a Catalytic Converter from a 3.7L Engine on Jeep Liberty?

First, you should elevate and steady the vehicle so you can reach the catalytic converter on 3.7L engines. Place heat valve lubricant on each bolt and nut, then give the lubricant 5 minutes to penetrate. Unattach the wires of the oxygen sensor and undo the nuts holding the front exhaust pipe and catalytic converter assembly to the muffler flange. After that, take out the bolts and flanged nuts from the manifold. Take the front exhaust pipe/catalytic converter assembly out of the mount at the transmission if you see one, then pull it out of the vehicle.

How to Install a Catalytic Converter on Jeep Liberty?

Once the front exhaust pipe is in position, move the catalytic converter into its holder, both are installed onto the exhaust manifold flange connection if there is one. At the front, secure nuts to both the exhaust pipe and catalytic converter to the muffler flange, but don't tighten them yet. Please make sure that there is at least 25.4 mm (1.0 in.) between the exhaust pipe and anything on the frame or under the vehicle. Tighten the bolt on the exhaust manifold at about 27 Nm (19 ft. lbs.), as well as the front exhaust pipe and catalytic converter assembly to muffler flange nuts, at the same torque. Set up the front pipe so it is connected to the exhaust manifold's flange, tighten the clamp to 10 Nm and finish with the remaining cap. Link the oxygen sensor's electrical connections, lower the vehicle and start it to see if any exhaust leaks are happening. Afterwards, look at the exhaust system to see if it has come in contact with any body panels and change whatever needs to be corrected.

The catalytic converter fitted in Jeep Liberty automobiles is an exhaust and emissions system that has as its main function to reduce the emission of gases such as Carbon Monoxide (CO), Hydrocarbons (HC), and Oxides of Nitrogen (NOx) into less hazardous products including water and Carbon Dioxide (CO2). The change is, in fact, a chemical one, and this is made possible by the use of catalysts in the form of platinum, palladium or rhodium set on a honeycomb base. For the years, Jeep Liberty has employed several types of the catalytic converters like the direct fit and the universal styles. Direct fit converters are developed to screw in seamlessly while the universal converter needs some modifications to be made before installation. There are also performance catalytic converters that are designed for high flow to help boost the engine performance while having to achieve the required catalyst effectiveness. For any car engine, catalytic converter is one of the most vital components and so, regular cleaning of Jeep Liberty's catalytic converter is very much necessary to prevent poor performance and fuel economy due to clogged or hot catalytic converter.
