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.

This would be interesting. Since I work at the dealer I'll have to check on this. Maybe I can get Steve to look at this n see what they do to the motor.

 

this was posted awhile back and I thinks its basically turns on your fans earlier blah1 blah! HPT FTW

 

quite possible, makes sense since it says for high ambient temp. conditions.

Usually SI gives us more info about the need for the reflash and what it does.

 

This would be interesting to find out what this really is and how much it costs?

 

probably just some basic stuff that cab be done thru hp tuners

 

Not Even for all the 2.4 LE5's that sucks! What about the Ion's and G5's and sky's ext...

 

Sooo... Where can I get this done?
