How to remove and install the exhaust manifold in Four cylinder engine on Lexus RX350?

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.

Lexus RX350 Exhaust Manifold

In Lexus RX350 Exhaust Manifold, hot gases of the six cylinders are directed to a single outlet and then go through the catalytic converter, muffler, and tailpipe. The Exhaust Manifold is connected to the cylinder head in each Lexus model year with a gasket that seals off the pressure and avoids toxic spillages and back pressure that could deprive the engine of power or endanger the passengers. On the RX350, cast iron is still common, but some years have applied welded stainless steel tubing with heat shields to ensure cabin floors are cool and adjacent components are not damaged. The two designs have the same fundamental purpose, to direct the flow in a flowing manner, although the tubular design on the later Lexus RX350 models causes less internal restriction, which means that the engine will be able to breathe easier and thus react faster. Other models even incorporate the catalytic converter or an oxygen-sensor port as an extension of the Exhaust Manifold itself, reducing the weight and complexity of the under-hood design. Due to the large temperature variation of Lexus RX350 in day-to-day driving, the Exhaust Manifold will experience continuous expansion and contraction and thus cracks may develop and lead to loud noise, reduced fuel economy, and harmful fumes. The Exhaust Manifold is normally robust, but timely replacement of a damaged Exhaust Manifold will ensure that engine balance is maintained and the luxury crossover is quiet and efficient by ensuring that proper scavenging of exhaust is done.
