How to remove and install an exhaust manifold on Four cylinder engine on Lexus ES350?

Disconnect the cable from the negative battery terminal. Raise the front of the vehicle and support it securely on jackstands. Working below the vehicle, remove the lower splash shields. Apply penetrating oil to the bolts holding the exhaust pipe to the manifold. After the bolts have soaked, remove the bolts retaining the exhaust pipe to the manifold. Separate the front exhaust pipe from the manifold. Unbolt the lower exhaust manifold braces and remove them from the engine. Also, disconnect the oxygen sensor connectors. Working in the engine compartment, remove the upper heat shield from the manifold. Remove the nuts and bolts and detach the manifold and gasket. Use a scraper to remove all traces of old gasket material and carbon deposits from the manifold and cylinder head mating surfaces. If the gasket shows signs of leaking, check the manifold for warpage with a straight edge. If the manifold is warped, it must be replaced. Position a new gasket over the cylinder head studs, noting any directional marks or arrows on the gasket that may be present. Install the manifold and thread the mounting nuts into place. Working from the center out, tighten the nuts or bolts to the torque in three or four equal steps. Reinstall the remaining parts in reverse order of removal. Run the engine and check for exhaust leaks.

Lexus ES350 Exhaust Manifold

Lexus ES350 Exhaust Manifold directs the flow of hot combustion gases away from cylinders and into a single outlet, allowing the rest of the exhaust system to complete the job in a clean and quiet manner. In all Lexus ES350, Exhaust Manifold bolts to the cylinder head with a tightly fitted gasket that prevents any leaks while directing flow through the catalytic converter, muffler, and tailpipe and keeps power-sapping backpressure from occurring. Early Lexus ES350 cars had heavy cast-iron Exhaust Manifold units that were known for their toughness and limited airflow; early versions switched to welded steel or stainless tubing, sometimes applied in conjunction with the catalytic converter and a sensor port, trimming weight and allowing for greater breathing. These lighter styles of Exhaust Manifold often wear heat shields that prevent any nearby parts and cabin floors from heating up. Because the Exhaust Manifold is exposed to constant temperature swings, it can crack, but timely replacement seals the fumes and protects the occupants from carbon monoxide and also allows the Lexus ES350 to maintain smooth acceleration and efficiency.

Should you need to purchase new auto parts for your vehicle, we strongly suggest you consider the genuine Lexus ES350 Exhaust Manifold available on LexusPartsNow.com. Our OEM Lexus ES350 Exhaust Manifold come with the reassurance of the manufacturer's warranty, a hassle-free return policy, and speedy delivery service, all at affordable prices online.

Q: How to remove and install an exhaust manifold on Four cylinder engine on Lexus ES350?
A:
Disconnect the cable from the negative battery terminal. Raise the front of the vehicle and support it securely on jackstands. Working below the vehicle, remove the lower splash shields. Apply penetrating oil to the bolts holding the exhaust pipe to the manifold. After the bolts have soaked, remove the bolts retaining the exhaust pipe to the manifold. Separate the front exhaust pipe from the manifold. Unbolt the lower exhaust manifold braces and remove them from the engine. Also, disconnect the oxygen sensor connectors. Working in the engine compartment, remove the upper heat shield from the manifold. Remove the nuts and bolts and detach the manifold and gasket. Use a scraper to remove all traces of old gasket material and carbon deposits from the manifold and cylinder head mating surfaces. If the gasket shows signs of leaking, check the manifold for warpage with a straight edge. If the manifold is warped, it must be replaced. Position a new gasket over the cylinder head studs, noting any directional marks or arrows on the gasket that may be present. Install the manifold and thread the mounting nuts into place. Working from the center out, tighten the nuts or bolts to the torque in three or four equal steps. Reinstall the remaining parts in reverse order of removal. Run the engine and check for exhaust leaks.
