Condition Some customers may comment on the engine overheating when driving aggressively
with accessory grille installed in addition to an outboard cooler installed.
Cause This may be due to outboard aero blockers restricting airflow to the outboard coolers,
causing the engine to overheat.
Correction If the vehicle is equipped with (RPO V18) outboard coolers and an accessory grille, the
grille blockers should not be installed. If installed, they should be removed.

GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
