  Q: How to replace the front exterior door handle on Chevrolet Avalanche 1500?

  A: The replacement process for the front door exterior handle begins with removing the trim panel as well as the water deflector from the door. Cotter pin devices allow users to detach the outside handle rod and lock cylinder rod from their specific rod holding points. Stand by while holding the outside handle with tape then disconnect its mounting nuts before removing the rubber cover to get to the outboard nut for releasing the door-lock cylinder from the outside handle assembly. Refer to appropriate guidance when dealing with a lock cylinder that is difficult to manipulate. Set the handle aside before proceeding with new handle installation on the vehicle. The inside of lock case and cylinder keyway need to receive gm p/n 12345120 or canadian p/n 726548 lubricant or equivalent before installing the door-lock cylinder within the outside handle housing. Secure the lock cylinder rod by attaching its clip to the main rod and the handle rod clip followed by tightening the outside handle mounting nuts to 9 n.m (80 lb in) torque. Reposition the rubber cover together with the water deflector as well as the trim panel.

A screwdriver will help you detach the wire harness block from the fuse block for removing the I/P wiring harness block from the car. Join the fuse block to the I/P wire harness block by inserting the retaining bolt and tighten it to 6 N.m (53 lb in). The installation process includes fitting the fuse block into the I/P until it clicks while performing wiring connector attachment to the fuse block then reattaching the right side end panel.

  Q: How to replace the right exhaust manifold on 4.8L, 5.3L, and 6.0L engines on Chevrolet Avalanche 1500?

  A: You need to begin the right Exhaust Manifold change procedure for 4.8l, 5.3l, and 6.0l engines by taking off the ignition coils along with the spark plugs. Start by elevating the vehicle and then remove the nuts on the Exhaust Manifold pipes. Lower the vehicle so you can remove the Exhaust Manifold bolts and manifold and gasket which you should discard the gasket. The Exhaust Manifold requires heat shield bolts removal to eliminate both the shield attachment parts from the Exhaust Manifold. When keeping the Exhaust Manifold you must inspect and clean it thoroughly. You should attach the heat shield along with its bolts to the Exhaust Manifold only when needed then tighten the bolts to 9 nm (80 inch lbs.). Proper bolt torque on the Exhaust Manifold will stop vehicle emission issues and ensure correct on-board diagnostics (OBD) ii system operation and check that all bolt holes have smooth threads without debris but avoid applying sealant to the first three threads on the bolt. Wrap the boundary of the Exhaust Manifold bolt threads with threadlocker gm p/n 12345493 (Canadian P/N 10953488) or equivalent material to the extent of 5 mm (0.2 inches). Install the Exhaust Manifold and new gasket before tightening the bolts starting from the middle of the two then moving to opposite sides until reaching the outside bolts. Finish the tightening at 25 nm (18 ft. Lbs.) using the same pattern. Use a flat punch to bend the Exhaust Manifold Gasket exposed edges at the front of the right cylinder head. The installation continues by raising the vehicle and installing Exhaust Manifold pipe nuts which should be tightened to 50 nm (37 ft. Lbs.) followed by vehicle lowering.
