2007 Chevrolet Aveo Exhaust Manifold Parts Questions & Experts Answers

• Q: How to replace the exhaust manifold on 2007 Chevrolet Aveo?

  A: The Exhaust Manifold replacement process begins with disconnecting both the battery negative cable and pre-converter oxygen sensor connector. Start by removing the Exhaust Manifold heat shield bolts accompanied by the heat shield and continuing to unscrew auxiliary catalytic converter nuts from the Exhaust Manifold. The procedure starts with taking out the Exhaust Manifold retaining nuts according to the defined sequence until the Exhaust Manifold with gasket becomes removable. The sealing surfaces of both the Cylinder Head and Exhaust Manifold require cleaning before adding the new Exhaust Manifold Gasket and Exhaust Manifold. Follow the specified sequence while installing Exhaust Manifold retaining nuts at 25 n.m (18 lb ft) then install the auxiliary catalytic converter nuts to the Exhaust Manifold and tighten them to 40 n.m (30 lb ft). Screw down bolts securing the Exhaust Manifold heat shield until they achieve torque of 15 n.m (11 lb ft). The last step involves reattaching the pre-converter oxygen sensor connector as well as the negative Battery Cable.
