CAMPAIGN: POWER STRG. PUMP SUPPORT BRACE FRACTURE
Model and Year: 1987 CHEVROLET CAMARO EQUIPPED WITH 2.8L V6 (RPO LB8, VIN CODE S) AND POWER STEERING
General Motors has determined that some 1987 Chevrolet Camaros may experience a fracture of the power steering pump support brace. This condition can in turn lead to possible fracture of the power steering pump mounting bracket and/or loss of the serpentine accessory drive belt. Loss of the serpentine drive belt would result in loss of air conditioning (if equipped), generator, power steering assist and engine water pump operation.
To correct this condition, the vehicle will be inspected for the correct power steering pump support brace and, if necessary, a new design brace will be installed. The power steering pump mounting bracket will also be replaced on all vehicles requiring the new design brace.
VEHICLES INVOLVED
Involved are all 1987 Chevrolet Camaro models equipped with 2.8L V6 engine (RPO LB8) and power steering.
Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
OWNER NOTIFICATION
Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of Owner Letter included with this bulletin).
DEALER CAMPAIGN RESPONSIBILITY
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Whenever a vehicle subject to this campaign is taken into new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the dealer, and arrangements made to make the required correction according to instructions contained in this bulletin.

SERVICE PROCEDURE: Vehicles Equipped with Air Conditioning
If the vehicle IS equipped with air conditioning, proceed as follows:
1. Inspect the engine for the presence of a four-point attachment rear brace from the power steering pump to the engine (see Figure 1, Item 1 - two attachments on the rear of the pump). If this brace exists, install Campaign Identification Label on the vehicle and return it to the customer.
2. If a three-point attachment rear brace is present (see Figure 1, Item 2 - only one attachment on the rear of the pump), then the power steering pump bracket should be replaced, and the three-point attachment rear brace should be replaced with a new four-point rear brace. ALL REPLACEMENT HARDWARE AND THE INSTRUCTIONS for installing the power steering pump bracketry for vehicles equipped with air conditioning, may be obtained by ordering the Service Package (P/N 10099904) from G.M.S.P.O. Install campaign identification Label when service package installation is complete.
Service Procedure: Vehicles Not Equipped with Air Conditioning
If the vehicle IS NOT equipped with air conditioning replace the power steering pump bracket with a new bracket (P/N 10137045) and a new four-point rear brace (P/N 10078906) as follows:
1. Remove accessory drive belt.
2. Remove power steering pump pulley.
3. Remove power steering pump bracket.
4. Remove wire retainer attaching wiring harness to rear power steering pump brace and discard. Attach new wire retainer P/N 3816659 in approximately the same location on wire harness.
5. Remove power steering pump rear brace (to be replaced with service brace P/N 10078906).
6. Remove lower bolt in rear of power steering pump. Replace with the new stud P/N 7831389 and torque to 40-60 Nm (30-45 lb. ft.). Note: "Dog Point" (pilot) end of stud goes into pump which leaves shouldered end of stud outside of hex.
7. Assemble power steering pump to the new bracket & torque to 40-60 Nm (30-45 lb. ft. ) (3 existing bolts).
8. Loosely assemble new rear brace P/N 10078906 to the engine by placing brace over exhaust manifold stud, loosely assembling existing nut on the stud and loosely assembling existing bolt in the side of engine block.
9. Attach new wire retainer P/N 3816659 (on harness) to hole provided in new rear power steering pump brace. (Retainer should orientate wire harness properly so harness is not pinched between rear brace and rear of power steering pump when it is installed.)
10. Inspect threads in boss on water pump where the power steering pump bracket attaches. If threads are stripped, the water pump should be replaced. Reference 1987 Camaro Service Manual (ST-368-87) Section 3B7 for water pump replacement.
11. Attach power steering pump and bracket assembly to engine while guiding pump rear studs into rear brace holes.
12. Torque existing bolt "A" (Fig. 2) to water pump to 30-40 Nm (22-30 lb. ft.) and torque existing bolt "B" (Fig. 2) to cylinder head to 40-60 Nm (30-45 lb. ft.)
13. Assemble one existing nut and new nut P/N 11508006 on rear of power steering pump at rear brace holes.
14. Torque nuts that secure the brace to rear of power steering pump to 40-60 Nm (30-45 lb. ft.). Torque existing bolt and nut that secures brace to manifold stud and engine block to 30-40 Nm (22-30 lb. ft.). Note: Make sure the rear brace is firmly against the rear of pump, exhaust manifold stud and the side of engine block when brace attachments are torqued.
15. Install power steering pump pulley. Front edge of pulley hub should be flush with end of shaft within + 0.25mm.
16. Install accessory drive belt. Adjust to specifications.
17. Install Campaign Identification Label.
CAMPAIGN IDENTIFICATION LABEL
Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label." Each label provides a space to include the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or ballpoint pen.
Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be Visible when the vehicle is brought in for periodic servicing by the owner. Apply "Campaign Identification Label" only on a clean dry surface.

Dear Chevrolet Owner:
This notice is sent to inform you that Chevrolet Motor Division is conducting a recall campaign that includes your vehicle.
REASON FOR THE RECALL
General Motors has determined that certain 1987 Chevrolet camaros equipped with 2.8L V6 engines may experience a fracture of the power steering pump support brace. This condition can in turn lead to possible fracture of the power steering pump mounting bracket and/or loss of the serpentine accessory drive belt. Loss of the serpentine drive belt would result in loss of air conditioning (if equipped), generator, power steering assist and water pump operation.
WHAT WE WILL DO
To correct this condition, your vehicle will be inspected for the correct power steering pump support brace and, if necessary, a new design brace will be installed. The power steering pump mounting bracket will also be replaced on all vehicles requiring the new design brace. This service will be performed for you at no charge.
WHAT YOU SHOULD DO
Please contact your Chevrolet dealer as soon as possible to arrange a service date. Instructions for this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be needed to schedule, process, and repair your vehicle.
The enclosed Owner Identification Reply Card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner reply card and returning it to us.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
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.
