Some 2000-2007 Taurus, 2000-2005 Sable, 2000-2003 Windstar, and 2004-2007 Freestar/Monterey vehicles, equipped with a 4F50N, AX4N, or AX4S transaxle, may exhibit an erratic fluid level reading on the transaxle dipstick and possible leaks around the filler tube and grommet. The condition may be due to a restricted transaxle vent. ACTION: Repair the transaxle vent restriction by replacing the transaxle vent with a 90° vent stem, small hose clamp, two (2) tie raps, and 24″ (61 cm) of 5/16″ (8 mm) vacuum hose. The 5/16″ (8 mm) vacuum hose will be routed from the 90° vent on the transaxle back to the cowl area, next to the brake master cylinder and tie rapped in place with the end of the hose facing down. Refer to the following Service Procedures. NOTE: ON WINDSTAR, FREESTAR AND MONTEREY SEAL THE COWL PANEL GRILLE (COWL TOP VENT PANEL) AREA, SEE TSB 06-14- 10. NOTE: LEAKS MAY BE MISDIAGNOSED AS COMING FROM THE PAN GASKET. ALWAYS FOLLOW WORKSHOP MANUAL, SECTION 307- 01 TO LOCATE THE SOURCE OF A LEAK, AND LEAK CHECK WITH BLACK LIGHT AND DYE. SERVICE PROCEDURE 1. 2. 3. 4. 5. 6. 7. 8. 9. Disconnect the mass air flow (MAF) sensor electrical connector. Disconnect the crankcase vent tube(s) from the air cleaner outlet pipe. Loosen the clamp and disconnect the air cleaner outlet pipe from the throttle body. Release the air cleaner housing clamp(s). Separate the air cleaner cover from the air cleaner tray. Windstar, Freestar and Monterey only: Remove cowl panel grille by following the procedure in TSB 06-14-10. Disconnect the shift cable if located over the top of the vent. Remove the vent, pull straight up on the vent with locking pliers, or carefully pry the vent from the transaxle case. Install the replacement 90° vent stem. Windstar, Freestar, Monterey, Taurus, and Sable with column shifter – Must face to the right rear of the vehicle with the flat edge of vent base parallel to the chain cover boss (Figure 1) Taurus and Sable with floor shifter – Must face to the rear of the vehicle with the flat edge of vent base parallel to the chain cover boss (Figure 2) 10. Install one end of a 24″ (61 cm) long piece of 5/16″ (8 mm) vacuum hose to the 90° vent stem and secure with a small hose clamp. 11. Route the vacuum hose back and up to the cowl area and down next to the brake master cylinder. Carefully tie rap the hose in place next to the brake master cylinder (do not tie rap to brake lines), be sure the end of the hose is facing down and not directly above anything hot. Windstar, Freestar, and Monterey (Figure 3, 4, and 5) Taurus and Sable with column shifter (Figure 6) Taurus with floor shifter (Figure 7)

MODELS: 2008-2009 Chevrolet Captiva 2008-2009 Saturn VUE CONDITION General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2008-2009 model year Chevrolet Captiva and Saturn VUE vehicles. Some of these vehicles have a condition in which the nut securing the power steering line to the power steering pump may loosen. If this were to occur, there may be a power steering fluid leak. In rare circumstances, the fluid could contact hot exhaust components resulting in a possible engine compartment fire. CORRECTION Dealer/retailers are to inspect the nut securing the power steering line to the power steering pump. If there are no signs of a fluid leak, retailers are to tighten the nut. If a fluid leak is present, retailers are to tighten the nut and check the fluid level. SERVICE PROCEDURE 1. Open the vehicle hood and inspect the power steering reservoir for evidence of a fluid leak. • If a fluid leak is present, clean and dry the affected area before proceeding to Step 2. • If a fluid leak is not present, proceed to Step 2. 2. Raise vehicle on a hoist. Refer to Lifting and Jacking the Vehicle in SI. 3. Remove the right front wheel to gain access to the power steering pump high pressure output line. Refer to Tire and Wheel Removal and Installation in SI. Important: Inspect the bottom side of the power steering reservoir and high pressure output line for evidence of a fluid leak. Clean the affected area, if required. 4. Using a 16mm open-end wrench, loosen the high pressure line tube nut (1). Do not remove the tube nut from the power steering pump. 5. Fully tighten the tube nut (1) by hand. 6. Note the position of the tube nut flats (2). 7. Using a 16mm open-end wrench, tighten the tube nut (1) 60-90 degrees (about 1 to 1½ hex flats). Do not tighten the tube nut more than 90 degrees (1½ hex flats). 8. Install the right front wheel. Refer to Tire and Wheel Removal and Installation in SI. 9. Lower the vehicle. Refer to Lifting and Jacking the Vehicle in SI. 10. If a power steering leak was found in Step 2 or 4, check the power steering fluid and add fluid if required. Refer to Checking and Adding Power Steering Fluid in SI.

Steering Vibration/Shudder/Moan During Parking Maneuvers on Dry Pavement (Install Power Steering Pressure (Inlet) and/or Return (Outlet) Hose Assembly) 1995-99 Buick Riviera 1997-2001 Buick Park Avenue, Ultra 2000-2001 Buick LeSabre 2000-2001 Pontiac Bonneville steering vibration, shudder or moan noise when steering during parking maneuvers on dry pavement. Correction Install a new power steering pressure (inlet) hose assembly on the following vehicles: • 1995-98 Buick Riviera • 1997-98 Buick Park Avenue and Ultra Install a new power steering pressure (inlet) and return (outlet) hose assembly on the following vehicles: • 1999 Buick Riviera • 1999-2001 Buick Park Avenue and Ultra • 2000-2001 Buick LeSabre • 2000-2001 Pontiac Bonneville 1. Verify that the power steering pump reservoir is full. • If fluid level is low, fill and check for leaks. • If power steering system has air in the system, perform the “Bleeding Air from Power Steering System” procedure as described in the Power Steering System sub-section of the Service Manual. Important: When performing the “Bleeding Air from Power Steering System” procedure, it is important that the front of the vehicle is supported by the lower control arms. If the vehicle is not supported by the lower control arms, the procedure may cause the strut bushing to dislocate and cause new concern. Verify that the accessory drive belt is in good condition and that the pulleys are not bent or damaged. Verify proper belt tension and operation of the belt tensioner. Check for power steering hose ground out conditions. Check for good engine idle and correct engine RPM. Check to see that the rear transaxle mount does not have a plastic assembly aid installed which is used 2. 3. 4. 5. 6.

Hose Fittings, Pressure and Return Line at Steering Gear and Pump The tube portion of the power steering hose assembly may disengage from the connector assembly for any of the following reasons: if not fully assembled. if snap ring is missing. if female port in power rack and pinion steering gear or power steering pump (3A674) is too shallow. if tube nut, power steering pressure hose (3A719) or power steering return hose end is not machined or formed properly. If the tube disengages at the steering gear housing fitting or power steering pump, check for a snap ring in the connector assembly before attempting to seat the tube into the connector assembly. The tube is fully engaged in its connector assembly when the snap ring (part of the connector assembly) is seated in the groove machined in the tube for this purpose. The tube will not pull out once properly engaged. Attempt to pull out using hand force. If the tube does not pull out, verify by properly filling system, starting the engine and turning the steering wheel lock- to-lock with the wheels on the ground and fully loaded. Check for leaks. If a leak still occurs, replace hose assembly with the correct service hose assembly which has the connector assembly pre-installed. Hose(s), Pressure—3.0L (2V) Engine Removal 1. Open hood. 2. Disconnect battery ground cable (14301). Refer to Section 14-01. 3. Remove drive belt (8620). Refer to Section 03-05. 4.
