Condition/Concern
Some customers may comment on vehicle reduced engine power with a Service Engine message displayed. Upon inspection, a technician may find DTC

This condition may be caused by snow or ice being ingested into the air cleaner housing and accumulating in the air cleaner element, resulting in restricted
airflow into the engine.
Recommendation/Instructions
Remove the air cleaner element. Refer to Air Cleaner Element Replacement in SI.
Inspect the air cleaner element for the following conditions:
•
Packed snow
•
Frozen ice
•
A soaking wet condition that would indicate previous snow ingestion
•
Excessive debris and contamination as a result of the ingestion
If any of the above conditions are observed, replace the air cleaner element. Remove any snow or ice that may have accumulated in the air intake duct and
install the radiator grille cover with the part number listed below.
Note: Winter covers for vans that are equipped with the Duramax® Diesel Engine are included with vehicle orders that ship to colder states and all regions of

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.
