How to Install a Catalytic Converter on a Jeep Liberty

Save

Installation of a new catalytic converter on your Jeep Liberty will improve the engine performance of your Jeep. If the converter becomes plugged it can over heat or limit the engines ability to breathe by limiting the flow of exhaust out of the engine. The converter is an important part of the exhaust system and while they are expensive to replace, they are necessary for the engine to run properly. Be sure to allow the exhaust to cool if the Jeep has been running before you start working on it. The pipe and converter get very hot when the engine is operating.

Things You'll Need

  • Metric socket set
  • Ratchet
  • Metric wrench set
  • Locate the front mounting flange from the front exhaust pipe for the catalytic converter. There are two bolts that secure the flange from the converter to the flange on the pipe.

  • Position the catalytic converter so the two flanges line up, insert the gasket between the flanges and insert the retaining bolts. Install two nuts on the mounting bolts and tighten them with a socket and ratchet or wrench.

  • Insert the mounting rod on the converter into the hanger under the cross member located near the center of the converter. This hanger is a rubber hanger that the mounting rod slides into.

  • Slide the tail pipe onto the output pipe on the rear of the converter and install the band clamp. Tighten the clamp with a socket and ratchet until it is tight but do not over tighten it or you will crush the pipe.

  • Start the engine and check for leaks in the exhaust system. If you find a leak, tighten the clamp or bolts needed to tighten up the pipes and close the leak.

Tips & Warnings

  • When you purchase a new catalytic converter for your Jeep, be sure you purchase any clamps, gaskets or bolts that you will need to mount the converter properly. Having the right parts will save you time running back to the parts store in the middle of the job.
