2009 Toyota Matrix Parts Questions & Experts Answers

• Q: How to install the exhaust manifold on 2009 Toyota Matrix?

  A: Start the exhaust manifold assembly by installing the No. 1 manifold converter insulator through 4 bolts which need proper torque of 12 Nm (122 kgf-cm, 9 ft-lbf). Next install two bolts for the No. 2 exhaust manifold heat insulator while torquing them to 12 Nm (122 kgf-cm, 9 ft-lbf). Mount the exhaust manifold converter sub-assembly with the new gasket and torque its 5 nuts to 37 Nm (377 kgf-cm, 27 ft-lbf). The installation process starts with a bolt and nut on the No. 2 manifold stay while torquing to 44 Nm (449 kgf-cm, 33 ft-lbf); next is the manifold stay with another bolt and nut that receives the same torque of 44 Nm (449 kgf-cm, 33 ft-lbf). After installing the air fuel ratio sensor you should place the No. 1 exhaust manifold heat insulator with 4 bolts using a torque of 12 Nm (122 kgf-cm, 9 ft-lbf). Inspect the compression spring length in the front exhaust pipe assembly using a vernier caliper because replacement is necessary when the measurement falls short of minimum specifications. Clean the converter section of the exhaust manifold with a brush then install the new gasket correctly while avoiding damage before adding 2 springs along with 2 bolts and torquing them to 43 Nm (440 kgf-cm, 32 ft-lbf) while connecting 2WD heated oxygen sensor cables. You must measure the compression springs and gaskets needed for the center exhaust pipe assembly before installing 4 bolts and 2 compression springs which should be tightened to 43 Nm (440 kgf-cm, 32 ft-lbf) after connecting it to exhaust pipe supports following suspension design. The center exhaust pipe assembly of 4WD systems must connect to 3 exhaust pipe supports before installation. Installation of the generator assembly and V-ribbed belt needs to follow engine under cover RH installation before reconnecting the cable to the negative battery terminal while some systems require system initialization when using the negative cable. Check for exhaust gas leakage as the last step.
