  Q: What steps are involved in replacing a damaged exhaust manifold on Chrysler PT Cruiser?

  A: Turbocharged models are equipped with an exhaust manifold and turbocharger assembly. If the exhaust manifold is damaged, it must be replaced as a complete unit. Begin by disconnecting the cable from the negative battery terminal, setting the parking brake, and blocking the rear wheels. Raise the vehicle and support it securely on jackstands. Remove the air filter housing and the coolant reservoir. Disconnect the MAP sensor and remove the power steering fluid reservoir from the Cylinder Head, positioning it off to the side without disconnecting the fluid lines. Remove the accelerator cable and the cruise control cable if equipped. Next, remove the upper heat shield bolts and the upper heat shield from the exhaust manifold, followed by the exhaust manifold support bracket. From under the vehicle, apply penetrating oil to the threads of the exhaust manifold-to-exhaust pipe studs and allow it to soak in before removing the exhaust pipe-to-exhaust manifold flange nuts. Remove the lower heat shield mounting nuts and the lower heat shield from the exhaust manifold, then remove the oxygen sensor. Proceed to remove the exhaust manifold bolts and nuts, followed by the exhaust manifold and gasket. Inspect the exhaust manifold for cracks and other obvious damage; if any damage is found, replace it. Clean the threads of the exhaust manifold bolts with a wire brush and inspect for damage, replacing any that are damaged. Use a scraper to remove all traces of gasket material from the mating surfaces and inspect them for wear and cracks, taking care not to scratch or gouge the surfaces. Inspect the exhaust manifold mating surface for warpage using a straightedge and feeler gauge, checking the cylinder head surface as well. If warpage exceeds specified limits, the exhaust manifold or cylinder head must be replaced or resurfaced. For installation, coat the threads of the exhaust manifold bolts and studs with an anti-seize compound, install a new gasket, and then the manifold, tightening the fasteners in several stages from the center out to the specified torque. Complete the installation in reverse order of removal, and after finishing, run the engine to check for exhaust leaks.
