Heat Shield, Driver Side

The first step for center Exhaust Heat Shield replacement includes vehicle elevation and exhaust system removal. The process to replace the center Exhaust Heat Shield starts with removing the guard loop bolts and the underbody propeller shaft guard loop from vehicles equipped with all-wheel drive (AWD). The Fuel Tank requires support before unbolt the strap that holds both it and the rear part of the center heat shield. First remove the rivets which connect the overlapping heat shields at their front and rear before taking off the shield. Push the new shield into position on the vehicle while matching front rivets to common points on the front heat shield before attaching the rivets. Secure the tank strap bolt at 25 nm torques while also using 18 ft. Lbs. As a reference torque value. Awd vehicles require reassembly of the propeller shaft underbody guard loop together with its bolts which should be tightened to 25 nm (18 ft. Lbs.). The exhaust system must be installed once the vehicle receives its proper descent.
