Heat Shield, Passenger Side

Start by supporting the vehicle while raising it before beginning to change the Exhaust Heat Shield on the dash panel. And remove the shield from the vehicle by disconnecting the engine shield bolts. A technician must uninstall the bolts and skid plate of the oil pan skid plate from 1500 series vehicles. After loosening the 2 rear oil pan skid plate bolts of 2500 series vehicles it is necessary to remove the 2 front oil pan skid plate bolts and the skid plate. The Catalytic Converter must be taken off if needed. Proceed to uninstall dash panel Exhaust Heat Shield nuts (2 or 4) before removing dash panel Exhaust Heat Shield (1 or 3) from its dash panel studs. You should fix the dash panel Exhaust Heat Shield (1 or 3) to the dash panel studs before securing it with dash panel Exhaust Heat Shield nuts (2 or 4) using a torque of 9 n.m (80 lb in). Restoration of the Catalytic Converter should only take place in case of need. Installation of the oil pan skid plate includes positioning the front bolts (2) which require a 28 n.m (21 lb ft) torque specification on 2500 series vehicles but they may omit front bolts on other models unless necessary. The 1500 series vehicle requires positioning of the oil pan skid plate before installing the slidable oil pan skid plate bolts according to a torque of 28 n.m (21 lb ft) if they are installed. Place the engine shield to the frame before securing and tightening all engine shield bolts to 20 n.m (15 lb ft). Finally, lower the vehicle.

Begin replacement of the Exhaust Heat Shield (1, 3) on the dash panel by raising and properly supporting the vehicle. Start by removing both the engine shield bolts and shield if required before unfastening the Exhaust Heat Shield nuts and removing the Exhaust Heat Shield (1, 3) from dash panel studs. The installation of the Exhaust Heat Shield (1, 3) must be done by attaching it to dash panel studs while paying attention to the fastener notice listed in service precautions. Install the Exhaust Heat Shield nuts after attaching them to the dash panel studs then tighten them to 9 nm (80 inch lbs.). Retry the engine shield installation with its bolts after removal by fastening each bolt to 20 nm torque value (15 ft. Lbs.). Finally, lower the vehicle.

Start the replacement process of exhaust heat shield by raising and supporting the vehicle properly. Begin by removing the engine shield bolts and shield if required and continuing with the removal of exhaust heat shield nuts. The exhaust heat shield (1, 3) must be removed next from its dash panel studs. You should mount the exhaust heat shield (1, 3) on dashboard panel mounting points and tighten the exhaust heat shield nuts to 9 Nm (80 inch lbs.). Secure the engine shield and its bolts with 20 Nm (15 ft. lbs.) torque when installation is possible. Finally, lower the vehicle.

Raising the vehicle for proper support starts the replacement process of the Exhaust Heat Shield (1, 3) mounted to the dash panel. Before installation of the Exhaust Heat Shield (1,3) on dash panel studs, engineers must remove engine shield bolts followed by engine shield and Exhaust Heat Shield nuts and Exhaust Heat Shield (1,3). Position the Exhaust Heat Shield (1, 3) on the dash panel studs following the fastener notice for correct assembly. Position the Exhaust Heat Shield (1, 3) on the dash panel studs and secure all nuts with a torque of 9 nm (80 inch lbs.). The procedure calls for reinstalling the engine shield after installation of its bolts at a torque of 20 nm (15 ft. Lbs.). Finally, lower the vehicle.

You should start replacement of Exhaust Heat Shield (1, 3) on the dash panel by properly supporting the vehicle and then lifting it. First remove the Exhaust Heat Shield nuts followed by removing the Exhaust Heat Shield items 1 and 3 attached to the dash panel studs. The heat shield can be removed from service only through the passenger wheelwell opening. Install the Exhaust Heat Shield (1, 3) through the passenger wheelwell before securing it to the dash panel studs when performing installation. Complete the fastener notice then torque the Exhaust Heat Shield nuts to 9 nm according to the service precautions. Finally, lower the vehicle.

First remove the exhaust Muffler using the previously provided instructions according to the engine type whether 4.8l and 5.3l engines or 6.0l and 8.1l engines. Start the installation by removing bolts on the Exhaust Heat Shield before taking off the shield on vehicles with short beds. Vehicle owners with short beds should reinstall the Exhaust Heat Shield correctly before securing its bolts at 9 nm (80 inch lbs.). Reinstallation of exhaust mufflers needs to follow engine type-specific installation instructions.

The replacement process for the Exhaust Heat Shield starts with exhaust Muffler removal. The installation of the Exhaust Heat Shield requires removing bolts from the 6 1/2 ft box and later removing the heat shield itself. You must also remove the heat shield bolts from an 8 ft box then proceed with removing the heat shield from its place. The process to install the Exhaust Heat Shield starts with vehicles that have an 8 ft box through shielding position placement followed by bolt installation and subsequent 9 nm (80 inch lbs.) torque tightening. The installation of the Exhaust Heat Shield starts with vehicles equipped with a 6 1/2 ft box by securing it with bolts while tightening them to 9 nm (80 inch lbs.). Finally, reinstall the exhaust Muffler.

Removal of the exhaust Muffler and the spare tire hoist must happen before starting to replace the Exhaust Heat Shield. Vehicles with 6 1/2 ft box require you to remove Exhaust Heat Shield bolts before taking out the Exhaust Heat Shield. Installation of the Exhaust Heat Shield begins by removing its bolts from the 8 ft box. After removing the bolts proceed with removing the shield itself. First install the Exhaust Heat Shield on vehicles with an 8 ft box while observing the fastener notice in service precautions and torque the Exhaust Heat Shield bolts to 9 nm (80 inch lbs.). Install the Exhaust Heat Shield and its bolts onto vehicles with a 6 1/2 ft box by following the duration of 9 nm (80 inch lbs.). The last installation steps involve reinserting the exhaust Muffler followed by the spare tire hoist.

The replacement of the right side Exhaust Manifold heat shield begins by taking out the right wheelhouse liner. You must first remove the Exhaust Manifold heat shield bolts and toss out the heat shield that sits on the Exhaust Manifold. Secure the new heat shield onto the Exhaust Manifold before using heat shield bolts to fasten it properly at 9 nm (80 lb in). The right wheelhouse liner can be installed after all steps have been completed.

A prepared vehicle can receive the replacement of its Exhaust Heat Shield from the dash panel through this procedure. Start by taking out the Exhaust Heat Shield nuts followed by removing both wheelhouse panels from the vehicle. Begin by detaching the Exhaust Heat Shield (1, 3) from the dash panel studs followed by its removal through corresponding wheelwells. Install heat shields (1, 3) by passing them into each wheelwell and secure the Exhaust Heat Shield (1, 3) to dash panel studs according to the fastener notice. The Exhaust Heat Shield nuts require a tightness of 9 n.m (80 lb in) during installation. Finally, lower the vehicle.

The process to replace the Exhaust Heat Shield begins by removing the exhaust Muffler as well as the spare tire hoist. To mount the Exhaust Heat Shield on vehicles with a 6 1/2 ft. Box you need to uninstall the bolts securing the heat shield before eliminating it from position. Individuals with an 8 ft. Box must follow the same procedure of Exhaust Heat Shield bolt removal before taking out the heat shield. Begin your installation by putting on the Exhaust Heat Shield of an 8-ft. Vehicle while properly installing the Exhaust Heat Shield bolts and tightening them to 9 nm (80 inch lbs.). When working on 6 1/2 ft. Box vehicles use the Exhaust Heat Shield and its bolts along with tightening them to 9 nm (80 inch lbs.). Place the spare tire hoist along with the exhaust Muffler back onto their respective positions.

The process of replacing the Exhaust Heat Shield from the dash panel should start by raising the vehicle and finding suitable support. The project starts with removing the engine shield bolts and shield (if present) before uninstalling the Exhaust Heat Shield nuts and Exhaust Heat Shield (1, 3) from dash panel studs. Attach the Exhaust Heat Shield (1, 3) on the dash panel studs by installing the Exhaust Heat Shield nuts according to a torque of 9 nm (80 inch lbs.). Reinstall the engine shield along with its bolts which should be tightened to 20 nm (15 ft. Lbs.). Lower the vehicle after completion.
