How to replace the exhaust manifold on a 4.2L engine on 2006 GMC Envoy?

Question

Accepted Answer

Raising the vehicle serves as the first step before replacing the Exhaust Manifold of a 4.2l engine. Begin the procedure by bagging the Exhaust Pipe from its bolts on the Exhaust Manifold after raising the car. Subsequently lower the vehicle to remove the manifold heat shield. After loosening the Exhaust Manifold bolts you must remove them before you can take out the Exhaust Manifold together with the Exhaust Manifold Gasket. Installing the Exhaust Manifold begins with using a new Exhaust Manifold Gasket followed by mounting the Exhaust Manifold itself. The installation of new manifold bolts requires application of threadlock gm p/n 12345493 (Canadian P/N 10953488). The first and second and final sequence of the Exhaust Manifold bolts requires tightening to 20 nm (15 ft. Lbs.). Position the Exhaust Manifold heat shield studs according to requirements then tighten them to 10 nm (89 inch lbs.) before placing the manifold heat shield. Use the lifting equipment to raise the vehicle so you can attach the Exhaust Pipe to the manifold using a sealing piece and install nuts which require 50 nm (37 ft. Lbs.) torque before lowering the automobile.
