2009 Toyota Sequoia Parts Questions & Experts Answers

• Q: How to install the water pump assembly on 2009 Toyota Sequoia?

  A: The first step for water pump assembly installation involves applying soapy water to a new O-ring on the water by-pass pipe. The water by-pass pipe end should be joined to the water pump using 5 bolts and 2 stud bolts along with a nut which must be tightened in multiple passes according to a specified torque of 21 Nm (214 kgf-cm, 16 ft-lbf) for bolts and 18 Nm (183 kgf-cm, 13 ft-lbf) for stud bolts and nut. Use Toyota Genuine Seal Packing Black, Three Bond 1215B or equivalent for continuous application on the designated areas. Specify the standard seal diameter at 2.0 to 3.0 mm (0.0787 to 0.118 in.) while avoiding contact surface oil and installing the water pump within three minutes. A new O-ring requires soapy water treatment before installation into the water inlet housing followed by temporary bolt attachment with 2 bolts experiencing uniform torque of 18 Nm (184 kgf-cm, 13 ft-lbf). The operator should install the water bypass hose into the water inlet housing. Remove the timing belt according to its necessary service schedule. Attach the cable to the negative battery terminal while tightening it to 5.4 Nm (55 kgf-cm, 48 in-lbf) and be prepared for potential system initialization tasks following this cable connection.
