Radiator Air Baffle Squeak Sound

A squeak sound may be heard coming from the front of the vehicle on some 2019-2023 Camaro models equipped with the 2.0L I4 turbo engine (RPO LTG) or the 3.6L V6 engine (RPO LGX). The sound emanates from the passenger’s side of the vehicle while driving over bumps. It also may be more noticeable once the engine has reached normal operating temperature.

The squeak sound on these engines may be caused by the radiator air baffle on the right side of the vehicle (Fig. 12) contacting the core support.

If this sound is heard, verify that the radiator air baffle is rubbing on the core support. There are two common areas where contact may occur. If there is contact, material should be trimmed from the air baffle in order to create more clearance between the baffle and the core support. (Fig. 13)

After removing the right-side radiator air side baffle, measure inboard and mark the horizontal and vertical edges as noted in Bulletin #22-NA-178.

Once measurements have been made, cut along the marked lines to modify the shape of the air baffle. (Fig. 14) Reinstall the radiator air side baffle and make sure there is proper clearance between the air baffle and the radiator core support.
