Exhaust Manifold in Chevrolet Blazer series vehicles plays a great part as it furnishes passage to hot exhaust gases from the engine to the exhaust system and further to the catalytic converter or muffler. Located differently from engine block to engine block, the manifold is designed to avoid intake reversion, which limits the flow of air to the engine. The Blazer models have applied various types of exhaust manifolds in the course of time, although this component is usually manufactured from cast iron or stainless steel. There are variants for these, called headers, which improves the flow resistance of the engine, thus increasing the exhaust velocity of the gases. These headers can increase performance through efficient exhaust gas scavenging and pressure control, in V8 engines, these engines may make used of H or X pipes for better control of exhaust pressure. Maintenance checks and timely replacement of the exhaust manifold is crucial to avoid decline in the car's performance and exposure of the passengers to the toxic gases.

Q: How to replace the right exhaust manifold on 4.8L, 5.3L, and 6.0L engines on Chevrolet Blazer?
A:
The replacement procedure for the right Exhaust Manifold on 4.8l, 5.3l, and 6.0l engines begins with Ignition Coil and Spark Plug removal followed by vehicle elevation and support. First remove Exhaust Manifold pipe nuts followed by lowering the vehicle to unlatch the Exhaust Manifold bolts and manifold with its gasket. Discard these items before moving ahead. Removing heat shield bolts along with shield components from the Exhaust Manifold becomes necessary for some repairs. Install new exhaust manifolds only if you plan to check them for cleanliness since a replacement is not needed. Use the heat shield together with its bolts to secure the Exhaust Manifold after proper bolt tightening to 9 nm (80 inch lbs.). The Exhaust Manifold bolts should receive their stated torque setting because improper installation degrades both emission performance and on-board diagnostics (OBD) ii system execution. The bolts which secure the Exhaust Manifold to the Cylinder Head must have thread-holes that are clear of dust and thread-lock compounds while excluding any sealant application from the first three threaded sections. A 5 mm (0.2 inch) wide coating of threadlock gm p/n 12345493 (Canadian P/N 10953488) or equivalent product needs to be applied to the Exhaust Manifold bolt threads. First tighten the center two bolts and then alternate between the sides when installing the Exhaust Manifold with its new gasket and bolts until they reach 15 nm (11 ft. Lbs.). Perform a final tightening phase to 25 nm (18 ft. Lbs.) by repeating the same side-to-side pattern. Use a flat punch to bend over the front part of the exposed Exhaust Manifold gasket at the right Cylinder Head. Finish by reinstalling spark plugs alongside ignition coils then raise the vehicle to put Exhaust Manifold pipe nuts in their place until they reach 50 nm (37 ft. Lbs.) torque before lowering it down.
