Some customers may comment that they hear a ticking noise coming from the engine
when cold.
Condition
⇒ This ticking noise will mainly occur during the first initial start in the morning.
Cause

start operation (not pumped up).
Correction
To correct this condition, follow the Service Procedure below.
Australia and New Zealand Dealers - Please refer to SEI-00000627 for further
information.

International, Federal, State, Provincial, and/or

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.
