SOME WIRE WHEEL LOCK WRENCHES SUPPLIED WITH THE VEHICLE MAY NOT FIT THE LOCK- ING BOLTS. THE LOCK WRENCHES IN QUESTION ARE ITT THOMPSON AND ARE COLOUR CODED BLUE. IF THIS SITUATION IS ENCOUNTERED, A NEW BLUE WRENCH SHOULD BE ORDERED FROM THOMPSON INDUSTRIES USING THE PROCEDURE DESCRIBED IN PRODUCT SERVICE BULLETIN #101, GROUP 100, JANUARY 15, 1981.
WHEN NEW CARS ARE SERVICED FOR DELIVERY, THE TECHNICIAN SHOULD USE THE WRENCH THAT COMES WITH THE VEHICLE TO INSTALL THE WHEEL LOCK NUTS. THIS WILL ASSURE THAT THE WRENCH AND LOCK NUTS ARE COMPATIBLE.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
