How to remove and install the exhaust manifold in Four cylinder engine on Lexus RX330?

Before lifting the exhaust manifold, the first thing that should be done is to disconnect the cable of the battery's negative terminal. Lift the front of the vehicle and set it on jackstands safely and then, take off the lower splash shields and front floor cover from the left side. Pry these bolts loose while being very careful not to remove the oxygen sensors by applying penetrating oil on the bolts that hold the exhaust pipe to the manifold and allowing them to soak before removal. Unfasten the exhaust neck from the manifold, undo the down exhaust manifold girders, and unsnap the connectors on the oxygen sensor. Situated in the engine compartment, it is necessary to take off only the upper heat shield from the manifold while observing that the last type of heat shield is not required to be detached. Remove the nuts/bolts and take off the manifold along with its gasket. For installation you will use a scraper to scrape the mating surface of the manifold and cylinder head cleaning it and during this process you will check for warpage if the gasket is in bad state and it is leaking. If changing a manifold only, bolt the lower heat shield onto the new one. Place a new gasket over the studs on the cylinder head and ensure the manifold is fitted Thread the mounting nuts starting with the middle one before you tighten all of them. Replace the rest of the parts in the reverse order you removed them, starting the engine to check for leakages through the exhaust.
