2002 Toyota Corolla Parts Questions & Experts Answers

• Q: How to service and repair the water pump on 2002 Toyota Corolla?

  A: Begin water pump service and repair by taking away the RH engine under cover followed by draining engine coolant then removing the drive belt. The water pump service requires you to remove 6 bolts then take out the water pump together with the O-ring while cleaning the engine coolant from the water chamber room yet keeping the RH engine mounting bracket and generator undisturbed. A visual inspection of the water pump drain hole must be performed to check for coolant leakage until the pump needs replacement if leakages exist. The pulley should be turned to test water pump bearing motion before replacing it if necessary. After installing the new O-ring on the timing chain cover, fit the water pump using its six bolts with an initial torque of 9 Nm (92 kgf-cm, 80 inch lbs.) for bolt A and 11 Nm (113 kgf-cm, 8 ft. lbs.) for bolt B. Both bolts have respective lengths at 30 mm (1.18 inch) for A and 35 mm (1.38 inch) for B. Installation should begin by reconnecting the RH engine under cover then adding the drive belt followed by engine coolant fill-up before engine startup for leak detection and ultimate engine coolant level reassessment.
