    Q:
    How to replace the right exhaust manifold on a 3.5L engine on Chevrolet Malibu? Posted by Customer
    A:
    A replacement of the right Exhaust Manifold for a 3.5l engine requires the heated Oxygen Sensor socket (J 39194-B) as part of the required tools. First detach the generator and disconnect the heated Oxygen Sensor (HO2S) electrical connector after removing the connector position assurance (CPA) retainer without damaging the attached pigtail. You should employ the heated Oxygen Sensor socket (J 39194-B) to achieve ho2s removal. The workflow proceeds with a three-step removal process of exhaust gas recirculation (EGR) pipe bolts that is followed by a controlled pipe relocation. Start by taking out the spark plugs and then remove the Exhaust Manifold nuts followed by the rear Catalytic Converter before extracting the Exhaust Manifold from its position. The Exhaust Manifold will require a new gasket applied to the cylinder head studs before returning the manifold to its position. First install the Exhaust Manifold nuts while torqueing them to 16 nm (12 ft. Lbs.) before reinstallation of the rear Catalytic Converter along with the spark plugs. Position the egr pipe according to needs before securing the three egr pipe bolts with a torque of 10 nm (89 inch lbs.). The Oxygen Sensor threads should receive nickel-based anti-seize compound equivalent to gm p/n 5613695 before installation through the heated Oxygen Sensor socket (J 39194-B) until the torque reaches 42 nm (31 ft. Lbs.). The ho2s electrical connector needs to be reconnected before installing the generator with its cpa retainer and securing the connector rosebud to its bracket.

    Q:
    How to replace the left exhaust manifold on a 3.5L engine on Chevrolet Malibu? Posted by Customer
    A:
    Before replacing a 3.5l left Exhaust Manifold one needs to gather a suitable set of tools that should include the heated Oxygen Sensor socket (J 39194-B). Start by removing the duct for air intake before extracting the connector position assurance retainer and disconnecting the heated Oxygen Sensor electrical connector. The sensor's operating performance can be damaged if the ho2s's permanently attached pigtail and connector are removed. The heated Oxygen Sensor socket (J 39194-B) should be used to undo the ho2s and complete the Exhaust Manifold heat shield bolt removal and shield uninstallation. Before lowering the vehicle first remove the spark plugs followed by the front Catalytic Converter and then disconnect the spark plugs. To start with remove Exhaust Manifold nuts followed by extracting the Exhaust Manifold and disposing the used Exhaust Manifold Gasket. To complete the installation apply a new Exhaust Manifold Gasket on the cylinder head studs before putting on the Exhaust Manifold while tightening its nuts to 16 nm (12 ft. Lbs.). The installation process should begin with front Catalytic Converter and Spark Plug replacement followed by heat shield and bolts installation with 10 nm (89 inch lbs.) tension. To install the Oxygen Sensor, apply gm p/n 5613695 nickel-based anti-seize compound to its threads and use heated Oxygen Sensor socket (J 39194-B) to tighten the ho2s to 42 nm (31 ft. Lbs.). Complete the process by reconnecting the ho2s electrical connector then installing the cpa retainer followed by putting back the air intake duct.
