The exhaust manifold on a Chevy S10 truck is changed by removing the spark plugs, unbolting the manifold from the cylinder heads, and unbolting the collector. The manifold can then be removed from the vehicle and a new set put in its place.
You just unbolt it. You first have to disconnect the exhaust pipe from the manifold then remove whatever you have to allow you to access the bolts and remove the manifold. It varies greatly from engine to engine. Some are easy and some are very hard.
The exhaust manifold needs to have a gasket in place to help seal the juncture between the manifold and the engine. After the gasket and gasket sealer are in place, tighten the bolts for the exhaust manifold. The exhaust pipe can then be replaced on the new exhaust manifold.
What engine???????? You should refer to repair manual if not familiar with auto repair and understand the terminology before attempting Remove nuts holding exhaust manifold to cylinder head & remove nuts/bolts holding exhaust manifold to exhaust pipes Use new exhaust manifold gaskets and install the new manifold securing the manifold to cylinder head (may need to but new nuts and or bolts) by "snugly" tightening manifold to cylinder head if not refering to repair manual
The purpose of the exhaust manifold is to connect the exhaust ports on the cylinder head to the exhaust pipe.
