  Q: How to replace the alternator on Chevrolet Cobalt?

  A: Start by turning off the negative Battery Cable and removing both the Drive Belt together with the air cleaner outlet resonator. The installer begins the generator removal process by disconnecting generator connectors after they remove generator bolts. Position the generator onto the engine before you install generator bolts to reach 22 n.m torque (16 lb ft). Attach the positive battery harness to the generator battery terminal while tightening the terminal nut to 20 n.m (15 lb ft). Connect the generator's harness terminals before you install the air cleaner outlet resonator and Drive Belt. Reconnect the negative Battery Cable as the last installation step.
• Catalytic Converter

  Q: How to replace the catalytic converter (LAP) (2.2L) on Chevrolet Cobalt?

  A: The first step to install a new lap (2.2L) Catalytic Converter is to lift your vehicle onto a support device. The first step involves removing the wheel drive shaft heat shield and heated Oxygen Sensor (HO2S) after that. You must detach the Catalytic Converter from its connections to the resonator pipe and Exhaust Manifold after removing their responsible nuts to extract the Catalytic Converter. Remove the exhaust gaskets from the system before cleaning both mating surfaces free of remaining gasket material. You should install a new gasket on the resonator pipe studs before fastening the Catalytic Converter to the pipe using 30 nm (22 lb ft) torque. Place back both the (HO2S) and the wheel drive shaft heat shield into its proper position. An inspection of the entire exhaust system for leaks undergoes completion.

  Q: How to replace the exhaust camshaft and lash adjuster on Chevrolet Cobalt?

  A: You can start the exhaust camshaft and lifter replacement by removing the camshaft cover along with the upper Timing Chain Guide. After installing the sprocket holding tool (J 43655) you must remove both intake and exhaust camshaft sprocket bolts while discarding them. Mark the camshaft caps as they are separated so you can easily return them to their initial positions before moving them forward. Cautiously loosen each bolt on each cap for a single turn before ending the spring tension on the camshaft and ultimately removing all caps together with the exhaust camshaft and roller followers and hydraulic adjusters. Before fitting the parts, apply lubricant to the valve tips and place the hydraulic lash adjusters and camshaft roller followers following the same alignment as the camshaft sprocket. Add the exhaust camshaft together with camshaft caps while employing a three-turn installation order to a final torque of 10 n.m (89 lb in). The installation continues with camshaft sprocket attachment to each camshaft while finishing with new bolts that receive hand tightening only. Implement the sprocket holding tool (J 43655) to eye up the camshaft sprocket bolts until they reach 85 n.m (63 lb ft) with an additional 30-degree angle. To complete installation place the upper Timing Chain Guide then tighten it to 10 n.m (89 lb in) while putting back the camshaft cover.
