2005 Chevrolet Cavalier Exhaust Manifold Parts and Q&A

• Q: How to replace the exhaust manifold on 2005 Chevrolet Cavalier?

  A: Starting the replacement of the Exhaust Manifold requires disconnecting the Battery Cable and removing the Exhaust Manifold heat shield. Begin by taking off the Oxygen Sensor followed by lifting up and suspending the vehicle. A bend of less than 3 degrees in any direction applied to the exhaust fox decoupler remains safe for operation. The Exhaust Pipe should be separated from the Exhaust Manifold by removing its attaching nuts followed by pulling down then back on the Exhaust Pipe. First modify the vehicle height before dismounting the Exhaust Manifold to cylinder head nuts and finally taking out the Exhaust Manifold. Thorough cleaning operations should be performed on every sealing surface before putting an Exhaust Manifold Gasket together with its cylinder head. Use new exhaust nuts together with retaining nuts for installation and torque them to 18 nm consistent with the specified sequence. After raising the car use a new Exhaust Manifold to flex coupler gasket to position the flex coupler at the Exhaust Manifold location. The retaining nuts should normalize to 30 nm (22 ft. Lbs.) during the process of securing the manifold to the flex decoupler. You should first lower the vehicle to reinstall the Oxygen Sensor after which you can attach the Exhaust Manifold heat shield before securing the bolts at 25 nm (18 ft. Lbs.). Complete the task by reestablishing the connection to the negative battery terminal.
