  Q: How to replace the endgate emblem/nameplate on GMC Canyon?

  A: Begin by getting your tools for this task which are a heat gun model J 25070 and 3M scotch brite molding adhesive remover disk (Part 3M P/N 07501). Apply border tape first to shield and keep the tailgate emblem in position. Set theHeat Gun (J 25070) 152mm (6in) away from the surface and apply its heat in circular motions to the emblem/nameplate for 30 seconds. Use a plastic tool to extract the emblem/nameplate from its current position while holding the 3M(TM) adhesive remover against both sides of the emblem and tailgate. Wipe the tailgate surface with varnish makers and painters (VMP) naptha. Set tape on surface to measure four dimensions if the emblem location needs precise placement. The measurements are 59.5 mm from tailgate edge to emblem at Dimension a, 12.1 mm from tailgate bottom to emblem at Dimension b, 5.1 mm from tailgate bottom to emblem at Dimension c, and 59.4 mm from tailgate edge to emblem at Dimension d. Preheat the tailgate with the Heat Gun (J 25070) to 21°C (70°F) surface temperature to avoid damaging the emblem/nameplate adhesive backing. Press the emblem/nameplate front side onto the tailgate with care as you open its backing to attach it permanently. Press and roll the emblem/nameplate on the tailgate to create a strong connection then check if the parts stick together before removing the tape around them.

  Q: How to replace the camshaft timing chain, sprocket, and tensioner on GMC Sierra 1500?

  A: During camshaft Timing Chain replacement alongside sprocket and tensioner you must first eliminate the engine front cover and Crankshaft position (CKP) sensor reluctor ring. The correct alignment of the rectangular-shaped ckp sensor reluctor ring requires facing the dish towards the engine front cover to protect both parts from damage. Mount the ckp sensor reluctor ring after you place its keyway correctly against the Crankshaft key. Use the rear pinion bearing race installer (J 5590) to push the ckp sensor reluctor ring until it rests fully against the Crankshaft sprocket before reinstalling the engine front cover.

Carefully remove the HO2S . The use of anti-seize compound GM P/N 12377953 or equivalent is recommended to coat sensor threads when reusing the same sensor because the HO2S threads require a special liquid graphite and glass bead blend that makes future uninstallations easier. Affix the HO2S and fasten it to a torque of 42 Nm (31 lb ft). The vehicle section requires installation of the CPA retainer after connecting the HO2S electrical connector to the engine wiring harness electrical connector.
