• Q: How to service and repair the exhaust pipe on 2004 Toyota Corolla?

  A: Service and repair of the exhaust pipe requires you to start by detaching the oxygen sensor through the removal of a clip then pulling away the floor mat before disconnecting the sensor connector and removing the sensor. You must first detach the tail pipe assembly through the procedure of removing two bolts as well as two springs. The front floor panel brace needs uninstallation through the removal of 2 nuts. The front exhaust pipe assembly needs two bolts and two springs to be removed for installation removal. The installation of front exhaust pipe assembly requires using vernier calipers to check the compression spring free length; it must measure 41.5 mm (1.634 inch) so a new spring is needed if the measurement is incorrect. Insert the new exhaust manifold gasket then connect the front exhaust pipe section with the 2 bolts and 2 springs while torquing them to 43 Nm (440 kgf-cm, 32 ft. lbs.). Insert the front floor panel brace using two nuts and tighten them to 30 Nm (302 kgf-cm, 22 ft. lbs.). To measure the compression spring in the tail pipe assembly, verify its free length should be 40 mm (1.575 inch). If the measurement does not match, replace the spring with a new one. The installation includes placing a new exhaust pipe front gasket followed by bolt attachment of the exhaust tail pipe using 2 springs and 2 bolts with torquing force set to 43 Nm (440 kgf-cm, 32 ft. lbs.). The oxygen sensor needs installation on the exhaust pipe front with 44 Nm (450 kgf-cm, 33 ft. lbs.) torque while connecting the oxygen sensor connector correctly but avoiding wire twisting since rewiring may be required. Check for any exhaust gas leak through a final step.
