OEM 2009 Toyota Tundra Intake Manifold

2009 Toyota Tundra Parts Questions & Experts Answers

• Q: How to install the intake manifold sub-assembly and related components on 2009 Toyota Tundra?

  A: Starting the installation requires setting new gaskets on each cylinder head with proper port hole alignment while maintaining correct installation direction. The intake manifold should be mounted between cylinder heads and 10 bolts need to be torqued to 26 Nm (265 kgf-cm, 19 ft-lbf) during multiple tightening passes starting at the inner bolts. Installation of the fuel delivery pipe sub-assembly follows the procedure. The installation process for the surge tank requires a new gasket before using an 8 mm hexagon wrench for mounting four bolts and two nuts to a torque of 28 Nm (286 kgf-cm, 21 ft-lbf). Use 2 bolts to fasten the No. 2 surge tank stay along with the No. 1 surge tank stay at a torque of 21 Nm (214 kgf-cm, 15 ft-lbf). Secure a bolt on the oil baffle plate to achieve a torque of 9.0 Nm (92 kgf-cm, 80 in-lbf) before installing the throttle body bracket with two bolts at 21 Nm (214 kgf-cm, 15 ft-lbf) while attaching the wire harness clamp. The vacuum switching valve (for ACIS) connector receives installation together with 2 wire harness clamps and the No. 1 ventilation hose and the union to check valve hose, purge VSV connector, and purge line hose which need their hose clamp directions confirmed before assembly. The installation requires connecting the No. 4 and No. 5 water by-pass hoses and the throttle position sensor and throttle control motor connector in sequence. Install the air cleaner assembly with element through 2 bolts that require 8.0 Nm (82 kgf-cm, 71 in-lbf) torque and create a hose clamp tightness with a height below 0.5 mm (0.0197 in.). Connect the MAF meter connector before adding wire harness clamps to the configuration and connecting the vacuum hose while securing the clamp with proper torque. Insert the pin completely into the grommet for the No. 2 air cleaner hose before you fasten it at 7.5 Nm (76 kgf-cm, 66 in-lbf) using two bolts and achieve 4.0 Nm (41 kgf-cm, 35 in-lbf) torque on the hose clamp. Connect the negative battery cable but initialization procedures should be performed on systems that require these steps. The technician should perform coolant addition followed by a leak inspection for engine coolant and fuel. The V-bank cover requires installation with 2 nuts at 7.5 Nm (76 kgf-cm, 66 in-lbf) torque before adding the front cowl top outer panel using 7 bolts to the same torque specification followed by washer hose connection. Installing the front wiper motor should be completed after both the front wiper motor and link assembly alongside the No. 1 engine under cover are placed.
