How to Install a Catalytic Converter on a 3.7L Engine on Jeep Grand Cherokee?

First, clip the steady rest bracket onto the front end of the exhaust pipe/catalytic converter assembly. After that, insert the front exhaust pipe/catalytic converter assembly into the vehicle and put the bolts and nuts on, just loosely, at the assembly's connection to the exhaust manifold. Once the pieces are assembled, slip in the nuts into the holes in the muffler flange, but don't tighten them yet. There must be no less than 25.4 mm (1.0 in.) between the exhaust pipe and the frame or other parts below the vehicle. Tighten the bolts at the front end of the assembly to the exhaust manifold to 26 Nm (19 ft. lbs.) torque and on the muffler flange to 47 Nm (35 ft. lbs.) of torque. Screw in the steady rest bracket bolts to 47 Nm (35 ft. lbs.), connect the wires from the oxygen sensor and install the crossmember under the transmission. When you've finished, lower the car, start it and check for leakage from the exhaust. Repair any issues as they arise.

How to Remove and Replace a Catalytic Converter on a 3.7L Engine on Jeep Grand Cherokee?

Before embarking on catalytic converter replacement, put the steady rest bracket onto the front assembly that includes the exhaust pipe and the catalytic converter. After that, join the front exhaust pipe/catalytic converter assembly with the vehicle body. Do not completely tighten the bolts and nuts at the front exhaust assembly as you fit them onto the exhaust manifold. In the same manner, fit the nuts onto the front exhaust pipe or catalytic converter assembly to the muffler flange so they are in place, but don't fasten them securely yet. Make certain the exhaust pipe is at least 25.4 mm (1.0 in.) above both the frame and any components below the vehicle. You should use 26 Nm (19 in. lbs.) torque when tightening the front exhaust pipe/catalytic converter assembly to the exhaust manifold, then tighten the front exhaust pipe and catalytic converter assembly to the muffler flange using 47 Nm (35 ft. lbs.) torque. Screw the steady rest bracket bolts and tighten them according to the manual which is 47 Nm or 35 ft. lbs. Next, fasten the electrical-cable ends of the oxygen sensor, mount the transmission crossmember, raise the car, start it and examine the exhaust system for leakage.

The Catalytic Converter in Jeep Grand Cherokee vehicles is a component that helps in the process of reduction of poisonous exhaust emission to harmless gases. This component is used sparingly with replacement the only usual activity that is carried out on it. Thus, preliminary requirements include avoiding an engine overheating, excluding contact of silicone-based sealants with the converter, and frequent oil change. Such symptoms as poor fuel economy, rough engine idling, rattling or shaking, blue smoke emission from the exhaust, and backfires are typical for a faulty converter. To ensure the required smooth exhaust flow and minimum emission of noxious fumes, the catalytic converter should be installed and operated correctly. Emission reforms have led to the development of different models of this part such as two-way model which has later on developed into the three-way catalytic converter.
