It is necessary to raise the vehicle before removing or installing the exhaust heat shield on the body panel. First, use a 1/4 inch (6 mm) drill bit to take out the rivets from the heat shields as required, then take off the exhaust tailpipe heat shield, muffler heat shield, and front exhaust pipe heat shield. Installation should start by putting the front exhaust pipe heat shield onto the vehicle, and fasten it using the J34940 Rivet Gun (J34940). Subsequently, put the muffler heat shield into place and fasten it with rivets using tool J34940. Finish by putting on the exhaust tailpipe heat shield and fastening it in place with the rivet gun J34940, then lower the vehicle.
