How to remove and install the exhaust manifold in 4.8L,5.3L,6.0L V8 engine on Chevrolet Express?

To remove the exhaust manifold, first disconnect the cable from the negative terminal of the battery, then remove the engine cover. Raise the vehicle and support it securely on jackstands. Apply penetrating oil to the exhaust pipe-to-manifold studs and nuts, and disconnect the electrical connector for the oxygen sensor. Remove the nuts retaining the exhaust pipe(s) to the manifold(s). Detach the spark plug wires and remove the spark plugs from the side being worked on; if both manifolds are being removed, detach all spark plug wires and remove all spark plugs. For the right side manifold, remove the inner splash shield from the fenderwell, noting that access is easier with the front wheel and inner fenderwell removed, though not absolutely necessary. Remove the oil dipstick, unbolt the dipstick tube bracket, and move the dipstick tube. Remove the EGR valve and pipe assembly, then remove the mounting bolts and separate the exhaust manifold from the cylinder head, followed by removing the heat shields from the manifold. For the left side manifold, remove the EGR pipe from the exhaust manifold and the inner splash shield from the fenderwell, again noting that access is easier with the front tire and inner fenderwell removed. Remove the mounting bolts and separate the exhaust manifold from the cylinder head, followed by removing the heat shields. For installation, check the manifold for cracks and ensure the bolt threads are clean and undamaged, making sure the mating surfaces are clean before reinstalling the manifolds. Install the heat shields, bolts, and gaskets onto the manifold, ensuring the retaining tabs hold the assembly together during installation. Place the manifold on the cylinder head and install the mounting bolts finger tight, then tighten the bolts from the center to the ends using a torque wrench, completing the process in two steps. If necessary, bend the exposed end of the exhaust manifold gasket back against the cylinder head. The remaining installation steps are the reverse of removal, and always use new O-rings and gaskets on the EGR valve and pipe assembly. Finally, start the engine and check for exhaust leaks.
