Allow to cool down before inspection / repairs. NOTE: Exhaust system parts do not need to be removed for this inspection / repair. 1. Raise the vehicle on a hoist. 2. Inspect the heat shields on the front exhaust tube for the following: • Heat shield contact with the exhaust tube. • Separated / missing band clamp(s). • Weld separation(s). 3. If a heat shield is found contacting the exhaust tube, pry it away to allow a minimum 1 mm (.040 inch) space. • Road test the vehicle to verify the repair. 4. If a weld or band clamp is separated, or the band clamp is missing, install new band clamps as needed. • For band clamp(s) location, refer to the pictures (starting on Page 5) that applies to your vehicle. 5. Secure the band clamp with the hex bolt located on the side (or on top, if needed). See Page 4, Figure 1 for example. WARNING: Do NOT install the hex bolt on the bottom of the exhaust tube. • Band clamp hex bolt torque: 4.0 – 5.5 N•m (0.4 – 0.56 Kg-m, 2.9 – 4.0 ft-lb) 6. After securing the band clamp, cut off the clamp’s excess at the end. • Wrap the end of the band clamp over the hex bolt, and then cut off the excess band clamp within 5 mm (0.2 inches) past the hex bolt (see Page 4, Figure 2). WARNING: Be careful of sharp edges after cutting off the excess band clamp. 7. After band clamp(s) installation, road test the vehicle to verify the repair. 3/9 NTB10-097 Hex Bolt Mounted On the Side of the Exhaust Tube Figure 1 Figure 2 4/9 NTB10-097 2007-2010 Altima Sedan and Hybrid, and 2008-2010 Coupe: QR25DE (4 cyl) engine 5/9 NTB10-097 2007-2010 Altima Sedan and 2008-2010 Coupe: VQ35DE (6 cyl) engine 6/9 NTB10-097 2009-2010 Maxima 7/9 NTB10-097 2004-2008 Maxima, 2004-2009 Quest, and 2005-2006 Altima with VQ35DE (6 cyl) engine and A/T.
