  Q: How to install the exhaust pipe on Scion xB?

  A:

  The installation of an exhaust pipe begins with measuring the compression spring's length with vernier calipers so check the length reaches 41.5 mm (1.634 in.) if not install a new compression spring. Join an exhaust pipe gasket to the exhaust manifold converter before using 2 compression springs along with 2 bolts that need 43 Nm (438 kgf-cm, 32 ft-lbf) of torque to install the front exhaust pipe. Install a new gasket on the front exhaust pipe before attaching the center exhaust pipe assembly through two bolts and No. 4 exhaust pipe supports with 43 Nm (438 kgf-cm, 32 ft-lbf) torques. Use 4 bolts to install the front floor center brace while applying torque of 51 Nm (520 kgf-cm, 38 ft-lbf). Assess the No. 2 center exhaust pipe assembly compression spring length that must be at least 38.5 mm (1.516 in.) before replacing it if necessary. A plastic hammer and wooden block assist in installing a new exhaust pipe gasket that reaches flush with exhaust manifold and center exhaust pipe assembly while maintaining correct installation direction to prevent gasket damage and re-use. The No. 2 center exhaust pipe assembly requires installation with 2 compression springs and 2 bolts that should be torqued to 43 Nm (438 kgf-cm, 32 ft-lbf). A plastic hammer should be used to uniformly drive a new tail pipe baffle into position through its keyway which should align with the protruding part of the exhaust pipe tail. For assembly of the No. 2 exhaust pipe connect a new gasket before attaching the tail exhaust pipe assembly with its 2 bolts and No. 4 exhaust pipe support. The procedure ends by installing the heated Oxygen Sensor followed by leak tests on the exhaust gases prior to fitting the No. 1 engine under cover.

  Q: How to remove the exhaust pipe on Scion xB?

  A:

  One must begin exhaust pipe removal for the 2AZ-FE engine by taking out the No. 1 engine under cover. After the Oxygen Sensor reaches temperature there will be a following step to detach it. The removal process starts with 2 bolt removal from the tail exhaust pipe assembly while taking off the No. 4 exhaust pipe support before eliminating the exhaust pipe gasket. A plastic hammer should be used for uniform tapping to extract the tail pipe baffle. Tear down the No. 2 center exhaust pipe assembly when you have removed its 2 bolts along with its 2 compression springs before you remove the No. 4 exhaust pipe support and the exhaust pipe gasket. You should remove the front floor center brace when you take out its four bolts. The next step requires detachment of the center exhaust pipe assembly along with its 2 bolts along with 2 No. 4 exhaust pipe supports and the exhaust pipe gasket. The front exhaust pipe assembly can be removed by disconnecting its 2 bolts together with 2 compression springs.
