  Q: How to service and repair the exhaust pipe assembly on Scion xA?

  A:

  Service and repair tasks on the exhaust pipe assembly can commence after shifting the shift lever knob sub-assy and removing the console box assy rear and floor panel brace front with their corresponding 2 bolts. The procedure starts with tail exhaust pipe removal after unboltage of its clamp and unfastening its bolt and separation of its exhaust pipe supports followed by exhaust pipe tail extraction alongside its gasket. The exhaust pipe assembly front requires removal of the 2 heated oxygen sensor connectors after which you should remove the grommet before unscrewing the 2 bolts and 2 compression springs. Begin by disconnecting the 2 exhaust pipe supports and then remove the exhaust pipe front. Perform the next step by removing both the exposed gasket from the exhaust manifold while also removing each of the 2 heated oxygen sensors. The first step in installing the exhaust pipe assy front includes adding the 2 heated oxygen sensors then torquing them to 44 Nm (449 kgf-cm, 32 ft. lbs.). Check the free length of compression springs with calipers since it should measure 40.5 mm (1.594 inch); get new springs when the length is less than that. A plastic-faced hammer needs to tap new gaskets flush with the exhaust manifold under the correct installation direction while using a wooden block and preventing reuse of the replaced gasket. After inserting and securing the exhaust pipe front it is necessary to add both compression springs and bolts which should be tightened to 43 Nm (438 kgf-cm, 32 ft. lbs.). Connect both heated oxygen sensor connectors before adding the grommet into place. You must place a new gasket on the exhaust pipe front then combine the 2 exhaust pipe supports before installing the exhaust pipe tail using a clamp and bolt which should be torqued to 32 Nm (326 kgf-cm, 24 ft. lbs.). Start by installing the floor panel brace front with 20 Nm torque (199 kgf-cm, 14 ft. lbs.) followed by the console box assy rear and ending with the shift lever knob sub-assy for manual transaxle.
