Q: How to install the exhaust pipe assembly on Toyota 4Runner?
A: The 2UZ-FE engine requires a new gasket before installing the exhaust pipe front to the exhaust manifold while securing the front exhaust pipe with 2 nuts tightened to 62 Nm (633 kgf-cm, 46 ft-lbf) torque specification. The installation of the No. 2 exhaust front pipe assembly requires placing two new gaskets and media between the manifold and front pipe before securing with two bolts and two nuts that should reach 62 Nm (633 kgf-cm, 46 ft-lbf) for the nuts and 48 Nm (489 kgf-cm, 35 ft-lbf) for the bolts. Vernier caliper examination of the exhaust pipe assembly center compression spring length must reveal at least 40.5 mm (1.5945 in.) otherwise replace the spring. Secure the exhaust pipe assembly front with 2 bolts and 2 springs while using a new gasket and tightening both bolts and springs to 43 Nm (440 kgf-cm, 32 ft-lbf). Put the exhaust pipe center gasket new on the tail pipe center then fasten it with two bolts tightened to 48 Nm (489 kgf-cm, 35 ft-lbf). The heated oxygen sensor for Bank 1 Sensor 2 requires installation on the exhaust pipe front with torque set to 44 Nm (450 kgf-cm, 33 ft-lbf) before connecting the sensor connector while checking for twisted wires that need removal and installation of the sensor. Reperform this method on the heated oxygen sensor for Bank 2 Sensor 2. Exhaust gas leaks need to be checked as the last step.
Q: How to install the exhaust pipe on Toyota Camry?
A: The installation of the 2AZ-FE engine exhaust pipe starts with front exhaust pipe No. 1 support bracket installation through 2 nuts with proper orientation followed by 33 Nm (337 kgf-cm, 24 ft-lbf) torque. The installation process includes fitting the heated oxygen sensor after it. After putting a new gasket on the front exhaust pipe assembly install 2 nuts while torquing them to 43 Nm (438 kgf-cm, 32 ft-lbf). Afterward, fasten the front exhaust pipe No. 1 support bracket using 2 nuts which require 33 Nm (337 kgf-cm, 24 ft-lbf) torque. The front exhaust pipe requires installation of a new gasket followed by attachment with two bolts and two nuts that should be torqued at 43 Nm (438 kgf-cm, 32 ft-lbf). First install the front exhaust pipe against the tail pipe assembly and attach it using 2 nuts which require a torque of 43 Nm (438 kgf-cm, 32 ft-lbf). Inspect exhaust gas leaks while performing necessary repairs of damaged parts to achieve proper leak prevention.
Q: How to install the exhaust pipe assembly on Toyota Tacoma?
A: A new compression spring should replace any existing spring that shows a measurement less than 40.5 mm (1.594 in.) when checked with vernier calipers. Free length assessment takes place before the 2TR-FE exhaust pipe installation process. A new gasket must be tapped into place by a plastic-faced hammer and wooden block while being checked for correct angle and keeping away from reused gaskets. Release the new gasket from being compressed by installing the exhaust pipe front in the exhaust pipe support. Then secure the 2 bolts and 2 compression springs with 43 Nm (438 kgf-cm, 32 ft-lbf) torque. Connect a new gasket to the exhaust pipe front followed by securing the exhaust pipe tail onto the 4 exhaust pipe supports through tightening both bolts and nuts to 48 Nm (489 kgf-cm, 35 ft-lbf). Set the cable to the negative battery terminal with a torque of 3.9 Nm (40 kgf-cm, 35 in-lbf). Afterward install the oxygen sensor along with the air fuel ratio sensor. Exhaust gas leakage should be tested as the last step.
