  Q: How to service the left-hand exhaust manifold on Ford Five Hundred?

  A:

  The service of the left-hand exhaust manifold begins with fan removal and HO2S electrical connector detachment. Before reinstalling the exhaust manifold to the Catalytic Converter you need to remove the two securing bolts while tightening them to 40 Nm (30 ft. lbs.). The service of the exhaust manifold requires nut removal from six points before reinstallation when users should fasten them to 20 Nm (15 ft. lbs.). Follow the removal process in reverse while replacing the manifold but first dispose the old gasket.

  Q: How to service the right-hand exhaust manifold on Ford Five Hundred?

  A:

  Service of the right-hand exhaust manifold requires neutral gear position along with a hoist-supported vehicle. Service of the right-hand Catalytic Converter begins with disconnecting the HO2S electrical connector as well as removing this component. You should extract the right-hand exhaust manifold heat shield by removing its three securing bolts while torquing them to 11 Nm (8 ft. lbs.) before reinstalling. The exhaust gas recirculation (EGR) system module tube needs to be detached from the exhaust manifold but must be tightened with a torque of 40 Nm (30 ft. lbs.) when you put it back. The six right-hand exhaust manifold nuts should be discarded and installed with a torque of 20 Nm (15 ft. lbs.). The installation requires new studs that need to be tightened to 12 Nm (9 ft. lbs.) after removing and discarding the three studs located toward the rear of the cylinder head. Remove the right-hand exhaust manifold with its gasket as you dispose of the gasket material. Complete the task by taking away the three remaining studs and installing them tightly at 12 Nm (9 ft. lbs.). To reinstall the exhaust manifold technicians must use new gaskets and studs as well as nuts requiring the reverse steps of removal.
