Removal & Installation
AWD Models

Specific to:

Jeep Compass 2007-2009

Jeep Patriot 2007-2009


CAUTION
The normal operating temperature of the exhaust system is very high. Therefore, never work around or attempt to service any part of the exhaust system until it is cooled. Special care should be taken when working near the catalytic converter. The temperature of the converter rises to a high level after a short period of engine operating time.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. Apply penetrating oil to the band clamp fastener of the component being removed.
    WARNING
    Do not use petroleum-based lubricants when removing/installing muffler or exhaust pipe isolators as it may compromise the life of the part. A suitable substitute is a mixture of liquid dish soap and water.

  6.  
  7. Remove the I-Pipe/Muffler assembly.
  8.  
  9. Disconnect the oxygen sensor electrical connectors.
    NOTE
    If the spherical gasket is to be reused, mark its orientation.

  10.  
  11. Remove the flange bolts (3), springs, and spherical gasket.
  12.  
  13. Remove the under floor catalytic converter (4) from the maniverter or catalytic converter assembly (1).
  14.  
  15. Clean the ends of the pipes to assure the mating of all the parts. Discard broken or worn isolators, rusted or overused clamps, supports, and attaching parts.
    NOTE
    When replacement is required on any component of the exhaust system, use original equipment parts, or an equivalent.

To install:


NOTE
When assembling the exhaust system, do not tighten the clamps until the components are aligned and clearances are checked.

  1. Install under floor catalytic converter and the isolator supports to the underbody .
  2.  
  3. Position the spherical gasket (2) with the white side facing the rear of the vehicle, install the springs, and bolts (3). Tighten the bolts to 24 ft. lbs. (33 Nm).
  4.  
  5. Install the I-Pipe/muffler assembly.
  6.  
  7. Working from the front of the system, align each component to maintain the position and proper clearance with the underbody parts.
  8.  
  9. Tighten the band clamps to 40 ft. lbs. (55 Nm).
    WARNING
    Band clamps should never be tightened such that the 2 sides of the clamps are bottomed out against the center hourglass shaped center block. Once this occurs, the clamp band has been stretched and has lost its clamping force and must be replaced.


    NOTE
    Maintain the proper clamp orientation when replacing clamps with a new clamp.

  10.  
  11. Start the engine and inspect for exhaust leaks. Repair the exhaust leaks, as necessary.
  12.  
  13. Check the exhaust system for contact with the body panels. Make the necessary adjustments, if needed.

  7. Loosen the intermediate pipe-to-catalytic converter clamp.
  8.  
  9. Remove the catalytic converter-to-exhaust manifold mounting nuts and gasket. Discard the gasket.
  10.  
  11. Remove the I-Pipe/Muffler assembly insulators, as necessary, to slide the catalytic converter out of the I-Pipe/Muffler.
    NOTE
    When replacement is required on any component of the exhaust system, use original equipment parts, or an equivalent.

  12.  

To install:

  1. Position the catalytic converter into the I-Pipe/muffler assembly.
  2.  
  3. Using a new gasket, position the catalytic converter against the exhaust manifold.
  4.  
  5. Install the flange nuts and tighten to 21 ft. lbs. (29 Nm).
  6.  
  7. Working from the front of the system, align each component to maintain the position and the proper clearance with the underbody parts.
