In order to replace a Catalytic Converter heat shield, first lift, and charmingly support the vehicle, taking into account the Catalytic Converter movement notice in service precautions. Next, support the exhaust system and remove the Catalytic Converter. Remove the oxygen sensor wiring harness from the Catalytic Converter heat shield, followed by the removal of the pop rivets that are securing the heat-shield and take off heat shield. To install, start with mounting the new Catalytic Converter heat shield and you can fix it with pop rivets. Reattach the oxygen sensor wiring harness to the heat shield and reinstall the Catalytic Converter, removing the support from the exhaust system. Lastly, check the exhaust system as well as underbody contact for leaks before lowering the vehicle.

You can start the Exhaust Heat Shield (Exhaust Pipe) replacement by properly supporting the vehicle in the air following vehicle lifting procedures. Service professionals need to pay attention to the Catalytic Converter movement notice which appears in service precautions. The first step requires supporting the exhaust system before removing the Catalytic Converter bolts. The exhaust system needs to be lowered by removing hanger bracket insulators to obtain better installation access if required. Move on to detach both bolts that secure the Exhaust Pipe heat shield before taking out the Exhaust Pipe heat shield itself. When reinstalling the Exhaust Pipe heat shield components, place the shield first before tightening its bolts to 2 nm (18 inch lbs.). Secure the exhaust system in its correct position and remount the hanger bracket insulators while tightening the Catalytic Converter bolts to 45 nm (33 inch lbs.). Complete your examination of the system by checking for leaks as well as underbody contact when the vehicle is at its lowest position.

Service of the heat shield begins with vehicle lift and suitable support following the set vehicle lifting protocols. Prior to servicing the Catalytic Converter a vehicle operator must follow the stated precautions in the Catalytic Converter movement notice in service. After supporting the exhaust system you must remove the Catalytic Converter from its position. First remove the wiring harness of the oxygen sensor from the Catalytic Converter heat shield before removing both the rivets and the heat shield together. First install the heat shield by attaching it to proper position then fasten it using the existing pop rivets. Insert the oxygen sensor wiring harness into the heat shield before reinstallation of the Catalytic Converter. The vehicle should undergo an inspection for leaks and contact with the underbody after support removal from the exhaust system before its subsequent lowering.

Properly raising the vehicle for maintenance work is necessary before you can replace the Catalytic Converter heat shield. Safety measures mentioned in the Catalytic Converter movement notice must be understood when performing service. Lean and secure the exhaust framework before you detach the Catalytic Converter. Begin the replacement of the heat shield by unplugging the heated Oxygen Sensor (H02S) wiring harness from the Catalytic Converter and then remove the rivets that secure the heat shield before finally removing it. Secure the new Catalytic Converter heat shield into position by using rivets for installation. Connect the heated Oxygen Sensor (H02S) wiring harness to the Catalytic Converter heat shield and reinstall the Catalytic Converter. Lower the vehicle and check the exhaust system for leaks after removing the support that holds the system.

The first step for Exhaust Heat Shield replacement requires suspending the vehicle. Start the procedure by taking off the exhaust system Muffler. A drill should be used to remove rivets at the exhaust Muffler heat shield before you take off the heat shield from the vehicle. To install the new part attach the exhaust Muffler heat shield through new rivets before putting back the Muffler and placing the vehicle back to its original position.
