2008 Toyota Sequoia Water Pump Parts Q&A

• Q: How to install the water pump assembly on 2008 Toyota Sequoia?

  A: The process for installing the water pump assembly requires installation of a new O-ring onto the water by-pass pipe followed by application of soapy water to the O-ring before connecting the pump to the pipe end. Logically tighten the water pump assembly using 5 bolts, 2 stud bolts along with a nut to reach a bolting force of 21 Nm (214 kgf-cm, 16 ft-lbf) for bolts while reaching 18 Nm (183 kgf-cm, 13 ft-lbf) with the stud bolts and nut simultaneously. Use Toyota Genuine Seal Packing Black, Three Bond 1215B or equivalent to apply seal packing as a continuous line to the specified areas while making sure the standard diameter falls between 2.0 to 3.0 mm (0.0787 to 0.118 in.) and clean the contact surface before installing the water pump within 3 minutes of sealing application. A new O-ring requires soapy water application before installation to the water inlet housing which needs temporary securing with 2 bolts at a torque of 18 Nm (184 kgf-cm, 13 ft-lbf). Fasten the water by-pass hose to the water inlet housing. When finishing the procedure you should disconnect the timing belt before securely reinstalling the negative battery cable with 5.4 Nm (55 kgf-cm, 48 in-lbf) torque. Initialization of systems might be required after reattaching the battery cable. An inspection of coolant leakage should be performed following engine coolant addition. According to the procedure you need to install the No. 1 engine under cover.
