To remove the exhaust manifold, first disconnect the cable from the negative terminal of the battery. Block the rear wheels, set the parking brake, raise the front of the vehicle, and support it securely on jackstands. Disconnect the downstream oxygen sensor connectors, then remove the engine middle splash shield by taking out the fasteners. Unbolt the exhaust pipes at the exhaust manifolds and lower the vehicle. In the engine compartment, disconnect the oxygen sensor's electrical connector. If removing the right exhaust manifold, detach the EGR pipe; if removing the left manifold, remove the air filter housing and the engine oil dipstick tube. Next, remove the exhaust manifold upper heat shield mounting bolts and the heat shields, then detach the manifold from the cylinder head, ensuring to spray penetrating lubricant on the bolts and threads beforehand. For installation, clean the mating surfaces to eliminate old gasket material and inspect the manifold for distortion and cracks, checking for warpage with a precision straightedge. Position the exhaust manifold with a new gasket and lower heat shields, installing the mounting bolts finger-tight while ensuring correct gasket identification. Tighten the mounting bolts starting from the middle and working outward in several increments to the specified torque. Finally, reinstall the remaining components in reverse order and start the engine to check for exhaust leaks between the manifold and cylinder head as well as between the manifold and exhaust pipe.

The first step is to disconnect the cable from the negative terminal of the battery.

Disconnect the oxygen sensors' electrical connectors and remove the sensors.
