To completely take out the intake manifold, one should first switch off the car power by removing the negative cable from the battery connector if at all the car has a radio system it should be activated with the correct code if it is an anti-theft system. Remove the coolant from the car and unbolt any varieties of coolant hoses associated with the intake manifold. Carbureted models need you to remove the carburetor while the fuel injected models need the air intake plenum to be removed. Then, take off the air injection pump and manifold, next, disconnect the bolt keeping the intake manifold-to-exhaust manifold bracket in place and take out the bracket. For fuel-injected models remove the fuel hose from the fuel rail. Modifications include; the removal of the heat shields at the exhaust manifold to get to the mounting nuts, removal of the power steering pump with the power steering hoses still connected, removal of the throttle valve linkage if at all it is connected and the removal of the EGR tube from the manifolds. Unbolster the nuts and bolts that connect the exhaust pipe to the exhaust manifold; use penetrating oil if needed and, if so, the oxygen sensor electrical connection as well. Last, but not least, undo the mounting bolts, nuts, and spacer to take off the manifolds from the engine. For installation, clean the mating surfaces, move such parts as may be required to the new manifold if you are replacing, place the new replacement gasket onto the cylinder head and finally fit the manifolds. Finally, you have to rotate the bolts in sequence from the center towards the ends to the required torque, replace the rest of the parts in reverse, and starts the engine for leakage check and functionality.

Remove the throttle body and air intake plenum, and then remove the fuel rail and injectors as an assembly from the intake manifold.
