INFORMATION
Subject:
Information on Internal Engine Noise or Damage After Oil Filter Replacement
Models:
2024 and Prior GM Passenger Cars and Trucks (Including Saturn)
Attention: This bulletin also applies to any of the above models that may be Export from North
America vehicles.
This bulletin has been revised to add the 2024 Model Year. Please discard Corporate Bulletin
Number 07-06-01-016H.
Important: Engine damage that is the result of an
incorrect or improperly installed engine oil filter is not a
warrantable claim. The best way to avoid oil filter
quality concerns is to purchase ACDelco® oil filters
directly from GMCCA. Oil filter misapplication may
cause abnormal engine noise or internal damage.
Always utilize the most recent parts information to
ensure the correct part number filter is installed when
replacing oil filters.
Note: This communication is not intended to
discourage the use of aftermarket oil filters. It is
intended to communicate that the correct oil filter
for the application be installed on the vehicle.
Today’s engines have precision clearances, and
technologies that require different oil filtration needs
than required in the past. Bearing clearances are
tighter, and the replacement of lead overlay to
aluminum overlay bearings has put an increased
significance on proper oil filtration, which is dependent
on oil filter paper area, and paper filtration efficiency.
Do not rely on physical dimensions alone. Make sure
that the oil filter used is made for the application
that it is being used on. Always ensure the parts you
install are from a trusted source. Installation of an oil
filter that is not designed for the vehicle may result
in catastrophic engine damage. Engine oil filters with
the same exterior dimensions may have filters paper
with reduced area, which is achieved by reducing the
number of pleats. Filtration efficiency can only be
determined by specialized tests.
New technologies have increased oil flow rate, resulting
in higher engine pressure differentials across the oil
filter, requiring oil filters with higher oil filter bypass
settings. Oil filters of the same size and with the
same threads may have significantly lower oil filter
bypass settings than required by today’s GM engines,
resulting in unfiltered oil to the engine bearings,
resulting in accelerated bearing wear and potential
bearing damage.
Refer to the appropriate Service Information (SI)
installation instructions when replacing any oil filter and
pay particular attention to procedures for proper
cartridge filter element alignment. If the diagnostics in
SI (Engine Mechanical) lead to the oil filter as the cause
of the internal engine noise or damage, dealers should
submit a field product report. Refer to the latest version
of Corporate Bulletin Number 02-00-89-002
(Information for Dealers on How to Submit a Field
Product Report). Canadian dealers should refer to the
latest version of Corporate Bulletin Number
10-00-89-006.
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.
