• Q: How to service and repair the exhaust pipe on 2003 Toyota Corolla?

  A: Service and repair of the exhaust pipe involves first unclipping the oxygen sensor while removing the floor mat before disconnecting the sensor connector to remove the sensor. Begin the exhaust pipe service by removing the tail pipe assembly through removal of 2 bolts and 2 springs. Work on the front floor panel brace by untightening 2 nuts. The front exhaust pipe assembly requires removal through the process of disassembling two bolts along with two springs. The installation process requires you to measure the compression spring free length with vernier calipers which should be 43 mm (1.693 inch), if not replace the spring. The exhaust pipe front connects with new manifold gasket while using 2 bolts and 2 springs and torqueing to 43 Nm (440 kgf-cm, 32 ft. lbs.). Fasten the front panel brace with 2 nuts that need proper torquing to 30 Nm (302 kgf-cm, 22 ft. lbs.). The measurement of the compression spring's free length for the tail pipe assembly should be 40 mm (1.575 inch) with replacement of the spring if required. After installing a new gasket on the exhaust pipe front the technician attaches the exhaust tail pipe with 2 bolts and 2 springs while torquing them to 43 Nm (440 kgf-cm, 32 ft. lbs.). Attach and tighten the oxygen sensor on the exhaust pipe front using 44 Nm (450 kgf-cm, 33 ft. lbs.), after which install the oxygen sensor connector but check the wire for proper alignment ensuring it is not twisted until redoing the sensor installation. Exhaust gas leaks should be checked as the final step.
