On the 2008 CTS (fig. 9), the engine compartment sight shields must be installed correctly to prevent the shields from contacting the inner hood liner.

During new vehicle PDI, or during service, when either the right or left side engine compartment sight shield is removed, follow these steps for installation:
1. Starting at the rear of the shield, install the shield to the shock tower brace (fig. 10). Ensure that the rear tab of the shield is engaged securely to the bottom side of the brace.

2. Ensure that the outboard edge of the shield lies under the hood seal (fig. 11).

3. Secure the shield to the fingers on the air box cover (LH side) and the ball stud (RH side).
