2003 Toyota Celica Water Pump Parts Q&A

• Q: How to service and repair the water pump on 2003 Toyota Celica?

  A: Proceed to service and repair the water pump by first removing the RH engine under cover together with draining engine coolant before you remove the drive belt. A 1ZZ-FE machine requires six bolt removal to disconnect the water pump as well as its O-ring from another bolt followed by water chamber room cleaning from all engine coolant. Special Service Tool: 09960-10010 (09962-01000, 09963-00600) must be utilized to remove the 4 water pump pulley set bolts followed by the water pump pulley and subsequent removal of the 6 bolts and water pump then O-ring and ensure complete removal of coolant from the water chamber room. The proper water pump replacement requires users to avoid removing the RH engine mounting bracket or generator from installation. The water pump must be checked for drain hole coolant leakages and bearing movement before the replacement decision. The installation process for the 1ZZ-FE engine requires a new O-ring on the timing chain cover followed by water pump installation with 6 bolts and torque values of Bolt A to 9.0 Nm (92 kgf-cm, 80 inch lbs.) and Bolt B to 11 Nm (113 kgf-cm, 8 ft. lbs.) with measurements of Bolt A being 30 mm (1.18 inch) and Bolt B measuring 35 mm (1.38 inch). The installation of the water pump with 6 bolts on 2ZZ-GE requires placing a new O-ring on the timing chain cover and applying torque to 9.0 Nm (92 kgf-cm, 80 inch lbs.). Next install the water pump pulley then tighten the 4 water pump pulley set bolts to 15 Nm (153 kgf-cm, 11 ft. lbs.) using Special Service Tool: 09960-10010 (09962-01000, 09963-00600). After reinstalling the RH engine under cover, drive belt, the system requires filling with engine coolant and engine operation to detect leaks and recheck engine coolant levels.
