Chances are you have one of the engines with an integral manifold. These cannot be removed from the cylinder head. These motors were notorious for cracks in the exhaust manifolds. That's the bad news.
The good news is that many of the 250 c.i. L6 motors from Chevrolet used the same head bolt/water & oil passage patterns so you may be able to swap the head for one from a 1974 or earlier motor. Or, if you want to swap for a 74 or earlier motor, they will go right in.
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
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.
You will need to remove the exhaust manifold retaining bolts in your 1993 Chevy Astro. Remove the exhaust manifold. Remove the exhaust manifold gasket and clean the surface. Reverse the process to install the new exhaust manifold gasket.
Remove the exhaust pipe from the exhaust manifold. Remove the manifold bolts. Remove the manifold. Remove the manifold gasket and clean the surface. Reverse the process to install the new manifold gasket.
what maniofold are you asking about? intake or exhaust, and what kind of engine do you have?
If it's an automatic you will have to remove the exhaust manifold because the thermostat is located on the backside of the engine on the driver's side under the exhaust manifold.
Its a bit of a job because it is held on by the same bolts as the intake manifold, and the easiest way is to remove them both, otherwise the rusted exhaust bolts holding the tubing to the manifold is the worst.
probably at the front of the engine underneath the exhaust manifold. Remove the heat shield on the exhaust manifold and you should be able to see it underneath.
Remove the intake manifold, exhaust manifold, and then remove the head.
Are you trying to remove the exhaust manifold,the muffler,or just the line running from the manifold connection to the muffler?
i have a 1998 ford Triton f 150 how do i remove the exhaust manifold right side
you will have to unbolt the exhaust pipe from the manifold pipe and then you unbolt the manifold pipe from the engine, remove old gasket and make sure both sides are clean of the old gasket and then install new gasket and bolt manifold back onto engine.
