Frame-Mounted Heat Shields
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The frame-mounted heat shields are attached to the top of the frame and crossmembers with bolts. The body must be lifted off the frame enough for access to the bolts that attach the heat shields to the top of the frame.
