2005 Chevrolet Malibu Exhaust Manifold Parts and Q&A

• Q: How to replace the right exhaust manifold on a 3.5L engine on 2005 Chevrolet Malibu?

  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.
