• Q: How to replace the water pump on 2004 Toyota Highlander?

  A: The first step to replace a water pump requires draining coolant followed by using Special Service Tool: 09249-63010 to remove both fan and generator V belt. Start by using Special Service Tool: 09960-10010 (09962-01000, 09963-00700) to remove 4 bolts and the pump pulley from the generator assembly and water pump. After that disconnect the crankshaft position sensor wire harness clamp. The water pump assembly removal requires the detachment of 4 bolts and 2 nuts and the bracket and subsequent removal of the water pump. Install seal packing (Part No. 08826-00080 or equivalent) to the water pump but first remove all old packing (FIPG) material from the contact surfaces and wipe the water pump area free of oil residue and execute the water pump installation within a 5-min window after application while waiting 2 hours before adding engine oil. Install the water pump together with its bracket by using 4 bolts and 2 nuts then torque them to 9.0 Nm (92 kgf-cm, 80 inch lbs.) before reconnecting the crankshaft position sensor wire harness clamp. Use Special Service Tool: 09960-10010 (09962-01000, 09963-00700) for installing the water pump pulley using 4 bolts which require torquing to 26 Nm (265 kgf-cm, 19 ft. lbs.). The procedure ends with coolant addition and leakage evaluation of engine coolant. The inspection includes draining the water pump to check for coolant leakage before assessing the pulley movement along with its silent operation of the bearings.
