Recall - Power Steering Pump Pressure Hose Replacement
88olds12SUBJECT POWER STEERING PUMP PRESSURE HOSE
ASSEMBLY CONTACTING TRANSAXLE GOVERNOR/SPEED SENSOR CONNECTOR
MODELS/YEARS CERTAIN 1986 AND 1987
TORONADO AND TROFEO MODELS
NUMBER: 87-C-12
DATE: June 1988
SECTION: 3B1
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1986 and 1987 Oldsmobile Toronado and Trofeo models. These vehicles may have insufficient clearance between the power steering pump pressure hose assembly and the transaxle governor/ speed sensor connector. This condition could cause abrasion of the power steering pump pressure hose assembly and result in a fluid leak. The location of the leak, near the exhaust manifold, combined with the high pressure of the fluid, could result in an underhood fire without prior warning.
VEHICLES INVOLVED
Involved are certain 1986 and 1987 Toronado and Trofeo model vehicles assembled at the Hamtramck Plant from the start of 1986 model year production through the end of 1987 model year production.
DEALER ACTION
To prevent the possibility of this condition occurring on vehicles involved, dealers are to replace the power steering pump pressure hose assembly, per the SERVICE PROCEDURE section of this bulletin.
Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of mileage, age of vehicles, or ownership from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your new vehicle inventory and arrange for the campaign correction to be performed.
SERVICE PROCEDURE
1. Open hood, cover right front fender, and disconnect negative battery cable.
2. Raise vehicle on hoist, remove heat shield and pipe retainer, disconnect power steering pump pressure hose assembly at gear. See illustration.
3. Lower vehicle, remove belt from power steering pump pulley and disconnect power steering pump pressure hose assembly at pump.
NOTICE: On some vehicles, it may be necessary to disconnect the return hose at the pump, remove the pump and pressure hose assembly from the vehicle, drain fluid from the pump, and mount the pump upside down in a vise (with the hose assembly up to prevent spring and flow control valve from failing out if union fitting on pump loosens). Spin off the pressure hose assembly.
The torque on the union at the pump should be checked for 75 N-m (55 Lbs.Ft.) if this method is used. To torque the union, the power steering pump pulley must first be backed off about 19 mm (3/4 inch) with tool J 25034-B to allow socket access to the union hex. Reposition the pulley using tool J 25033-B.
4. Reverse Steps (2) and (3) to install new power steering pressure hose assembly, Part Number 26013680. See illustration for torques and routing information. Connect negative battery cable.
5. Fill and bleed power steering system, following procedure outlined below:
A. Raise the front of vehicle until the front wheels are off the ground.
B. Make sure power steering reservoir is filled with power steering fluid to the proper level and maintain level during Steps (C) and (D).
C. With engine turned off (not running), slowly turn the steering wheel from lock to lock.
D. Have an observer watch the fluid in the reservoir as the steering wheel is being turned. Continue turning steering wheel until air bubbles are no longer seen rising from the fluid.
6. Check system for leaks and proper operation.
7. Install a Campaign Identification Label.
8. Remove fender cover and close hood.
CAMPAIGN IDENTIFICATION LABEL
Each label provides space to print the campaign number and the five (5) digit dealer code of the dealer performing the campaign. Insert this information with a typewriter or ballpoint pen. When installing label, clean and dry the surface of the radiator support tie bar and apply the campaign label where it is readily visible.
