Exhaust System Description: Shields
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The heat shields are aluminum; they prevent exhaust system head from penetration the floor of the vehicle or the fuel tank. Inspect the shields for cracks and tears. Shields must always be re-installed if they are removed for exhaust system or body repairs.
