How to replace the left side exhaust manifold on a 4.3L engine on 2008 Chevrolet Silverado 1500?

One must begin the left side Exhaust Manifold replacement (4.3L) process by lifting and stabilizing the vehicle for work. Starting by removing Exhaust Manifold nuts from the Catalytic Converter you can yet lower the vehicle to a safe position. Start by removing Exhaust Manifold heat shield bolts followed by its shield then move onto triggering off the spark plugs. Unwind Spark Plug Wires if required before you disconnect all bolts and the single stud mounting the Exhaust Manifold. Then discard the gaskets which you took out from the Exhaust Manifold before completely removing it along with the Exhaust Manifold to Catalytic Converter seal. Start by inserting a new Exhaust Manifold to Catalytic Converter seal into the relief area of the Catalytic Converter before properly positioning the Exhaust Manifold with its studs attached to the converter. Install new Exhaust Manifold gaskets between the manifold and cylinder head while fitting the Exhaust Manifold bolts alongside their stud until torque reaches 30 n.m (22 lb ft). After placing the spark plugs in position you should guide the Exhaust Manifold heat shield onto its position on the manifold while installing its bolts which require tightening to 9 n.m (80 lb in). After raising the vehicle again install the Catalytic Converter through its manifold connections and apply torque to 50 n.m (37 lb ft) before letting the vehicle down.
