Power Steering System Squeaking Noise Repair Procedure AFFECTED VEHICLE RANGE CONDITION SUMMARY: POWER STEERING SYSTEM SQUEAKING NOISE Situation: On some S-Type, X-Type and XJ Range vehicles within the VIN ranges above, a squeaking noise may be apparent from the power assisted steering system when the steering wheel is rotated in either direction. The noise is caused by a seal inside the steering rack. The noise can be transmitted through the steering column and steering wheel, making it difficult to diagnose. This bulletin does not address any other PAS noises, such as pump or drive belt related noises. Action: In the case of a verified customer complaint matching the description above, refer to the Repair Procedure detailed in this bulletin and complete the service fix.REPAIR PROCEDURE PAS SQUEAK/FLUID ADDITIVE Open driver’s door. Ensure the gear lever is in either neutral or park, the parking brake is ‘ON’, and the ignition is ‘OFF’. Open hood and install fender protectors. 4. Remove the power steering fluid reservoir cap (and filter mesh on XJ and S-Type vehicles) and ensure the fluid level is correct. (Figure 1) 5. Using a suitable clean syringe, remove 50 ml of steering fluid. NOTE: The fluid additive must only be added once and the supplied label must then be affixed to the power steering fluid reservoir. 6. Replenish the power steering fluid reservoir with 50 ml of the specified fluid additive (C2S 48887). 7. Affix the supplied label to the power steering fluid reservoir NOTE: Suitable temperature reading equipment must be positioned into the power steering fluid reservoir, (filter mesh must be removed on XJ and S-Type vehicles) and that the temperature can be read while carrying out the heating process. 8. Insert the temperature reading equipment probe into the power steering fluid reservoir (about halfway into the depth of the fluid). HEATING THE STEERING FLUID TO 100°C +/- 5°C (212°F +/- 10°F) 1. Turn ignition ‘ON’ and start the engine. With the engine idling, turn the steering wheel from lock to lock four times to cycle the fluid additive into the system. (Figure 2) CAUTION: Under no circumstances hold the steering wheel on full lock while heating the steering fluid (to avoid damage to the steering system). CAUTION: While carrying out the following procedure, ensure that 105°C (221°F) is not exceeded. 3. While stationary and with the steering wheel in the center position (road wheels in the straight ahead position), turn the steering wheel 90° (quarter turn) right and hold firmly with both hands. (Figure 3) ^ Increase the engine speed to 3000 rpm. ^ Monitor the power steering fluid temperature until 100 +/- 5°C (212°F +/- 10°F) is reached. PERFORMING THE STEERING MANEUVER NOTE: The steering maneuver should be carried out on a hard flat surface outside of the workshop. CAUTION: Do not hold the steering wheel on full lock for more than two seconds as this may cause damage to the steering system. 1. Verify the power steering fluid temperature is at 100 +/- 5°C (212°F +/- 10°F), engine idle speed set between minimum 900 rpm and maximum 1000 rpm. 2. Turn the steering wheel to full lock and hold for two seconds.

SUBJECT: MODELS: Loss of Power Steering Assist – Replace Electric Power Steering Motor 2005-2010 Chevrolet Cobalt 2005 Pontiac Pursuit 2005-2006 Pontiac G4 2006 Pontiac G5 Pursuit 2007-2010 Pontiac G5 Equipped with Electric Power Steering 2005-2010 model year Chevrolet Cobalt vehicles; 2005 model year Pontiac Pursuit; 2005-2006 model year Pontiac G4; 2006 model year Pontiac G5 Pursuit; and 2007-2010 model year Pontiac G5 vehicles equipped with electric power steering. Some of these vehicles have a condition in which a sudden loss of power steering assist could occur at any time while driving the vehicle. If the power steering assist is lost, a chime will sound and a “Power Steering” message will be displayed in the Driver Information Center to inform the driver of the condition. Steering control will be maintained, as the vehicle defaults to a manual steering mode. If power steering assist is lost, it may require greater driver effort at low vehicle speeds, for example, below 15 mph (25 km/h). Unless a driver compensates for this additional effort, it may increase the risk of a crash. Typically, the next time the vehicle is started, the power steering assist will return and the “Power Steering” message will no longer be displayed. EPS Motor Replacement Procedure Note: The use of Loctite is no longer required. Loctite should not be used for any further applications. 1. Connect the Tech 2® to the vehicle and check for diagnostic trouble codes (DTCs). 2. Record any present DTCs on the repair order and during claim submission. 3. Clear any DTCs that are present. 4. Remove the power steering assist motor. Refer to Power Steering Assist Motor Replacement in SI. Note: For 2005 model year vehicles only: Do NOT install the o-ring between the motor assembly and the steering column assembly. The new service motor kit will include an o- ring, but DO NOT install the o-ring for 2005 model year vehicles only. 5. Install the new power steering assist motor. Refer to Power Steering Assist Motor Replacement in SI. 6. Perform Test Drive.
