The vehicle installation process for 4-wheel drive (4WD) models includes removing the ho2s connector from the crossmember and disconnecting the cpa retainer and the electrical connector. When reinstalling the original bank 2 ho2s sensor the threads should receive an application of anti-seize compound gm p/n 12377953 or equivalent due to specialized gear designed to ease ho2s thread removal. Secure the bank 2 ho2s using torque to 42 n.m when installing (31 lb ft). Connect the ho2s electrical connector to both the harness and cpa retainer. 4wd vehicles require ho2s connector installation on the crossmember after which electrical connector and cpa retainer connections should be restored. First reinstall the ho2s connector to the crossmember while reconnecting both electrical connector and cpa retainer for vehicles with automatic transmission along with 2wd system. Before lowering the vehicle install the ho2s connector to the crossmember for manual transmission and 2wd and reconnect the electrical connector with the cpa retainer.

  Q: How to replace the endgate emblem and nameplate on GMC Sierra 1500 Classic?

  A: One needs a combination of tools to replace the endgate emblem and nameplate starting with these essential components: The technical tools required include a Heat Gun (J 25070) as well as a 3M TM Scotch Brite Molding Adhesive Remover Disk with part number 07501. First tape should be placed around the endgate emblem area for protection and alignment. Heat the emblem/nameplate using the heat gun (J 25070) with its nozzle 152 mm (6 in) from the surface for 30 seconds while moving in circular motions. To detach the endgate emblem/remove nameplate professionals should use a plastic flat-bladed tool then erase residual adhesive from both endgate surfaces and emblem/back using adhesive remover disks (3M(TM) P/N 07501). Wash the endgate surface using varnish makers and painters (VMP) naptha chemicals. Apply tape for guidance in unmarked areas. Use the heat gun (J 25070) to heat the endgate panel surface up to at least 21°C (70°F) without touching the emblem/nameplate adhesive layer. Press the front section of the emblem/nameplate onto the endgate panel as you proceed with removing its backing. Begin hand rolling the emblem/nameplate for adequate adhesion while checking for bonding until all tape enclosing the endgate emblem can be fully removed.

  Q: How to replace the rear side door window motor on GMC Sierra 1500 Classic?

  A: The procedure for rear side door Window Motor replacement starts with raising the window and proceeds to window removal for access when the Window Motor is nonfunctional. You should begin by eliminating the door trim panel alongside the water deflector and door speaker before applying support to the window. Detach the wiring harness from the motor before unbolting the 3 pieces (115 100 01) from its front side. The housing of the cable gear should not be dislodged because it can lead to the cable being removed from the spool. To remove the motor from the Window Regulator assembly disconnect it from its cable housing by observing motor orientation during gentle wiggling motion. The motor installation requires fitting the components through the cable housing before screwing the 3 bolts (115 100 01) tight to 5 n.m (44 lb in). The first step is to restore the window if removal occurred before reconnecting the wiring harness to the Window Motor and removing the window support. Use the wire connector to test the window operation through the switch before reinstalling the speaker followed by the water deflector and door trim panel.
