2008 Chevrolet Aveo Exhaust Manifold Parts Questions & Experts Answers

• Q: How to replace the exhaust manifold on 2008 Chevrolet Aveo?

  A: The process of Exhaust Manifold replacement begins by cutting the ties between the negative Battery Cable and pre-converter oxygen sensor connector. The Exhaust Manifold heat shield bolts as well as the shield must be removed before taking out the auxiliary catalytic converter nuts from the Exhaust Manifold. The necessary next step involves removing the Exhaust Manifold retaining nuts in their specific sequence to extract the Exhaust Manifold combined with the gasket. The sealing surfaces of the Exhaust Manifold and Cylinder Head must be cleaned before adding the new gasket followed by the Exhaust Manifold installation. Connect the Exhaust Manifold retaining nuts first before adding the auxiliary catalytic converter nuts to the Exhaust Manifold. Tighten these two sets of nuts to their specified torque values of 25 n.m and 40 n.m. Replace and fasten the Exhaust Manifold heat shield using bolts that should be tightened to 15 n.m (11 lb ft). Before completion disconnect the pre-converter oxygen sensor connector and the negative Battery Cable.
