2003 Chevrolet Malibu Exhaust Manifold Parts Questions & Experts Answers

• Q: How to replace the right exhaust manifold on 2003 Chevrolet Malibu?

  A: The exhaust crossover pipe together with the egr pipe and Oxygen Sensor need removal before starting right Exhaust Manifold replacement. After raising the vehicle remove the Catalytic Converter followed by disconnecting the Exhaust Manifold heat shield bolts and then the heat shield itself. When changing the Exhaust Manifold you should first remove all Exhaust Manifold nuts before extracting the Exhaust Manifold from its position along with its gaskets. Perform surface cleaning at the cylinder head and Exhaust Manifold areas before you put in both the Exhaust Manifold Gasket and the Exhaust Manifold. Fasten the Exhaust Manifold nuts to 16 nm before adding the Exhaust Manifold heat shield followed by heat shield bolt installation at 10 nm torque. The last step involves reinstalling the Catalytic Converter followed by lowering the vehicle before continuing with Oxygen Sensor and egr pipe connection and finishing the process by installing the exhaust crossover pipe.
