2001 Toyota Corolla Water Pump Parts Q&A

• Q: How to service and repair the water pump on 2001 Toyota Corolla?

  A: Service and repair of the water pump begins by removing the RH engine under cover followed by draining the engine coolant and removing the drive belt. You should start by removing the water pump by taking the 6 bolts out together with the water pump component and the O-ring before cleaning the engine coolant from the water chamber room. The process of water pump replacement requires drivers to keep both the RH engine mounting bracket and generator in position. You should examine the water pump by looking at its drain hole for any coolant leakage before performing a water pump replacement if leakage occurs. Turn the pulley to check for smooth and quiet movement of the water pump bearing and consider replacing the water pump as needed. The installation procedure requires installing a new O-ring on the timing chain cover followed by installing the water pump using six bolts which should have Bolt A tightened to 9 Nm (92 kgf-cm, 80 inch lbs.) while Bolt B receives 11 Nm (113 kgf-cm, 8 ft. lbs.) torque with Bolt A measuring 30 mm (1.18 inch) while Bolt B has a length of 35 mm (1.38 inch). The procedure requires reattaching the RH engine under cover and drive belt installation followed by engine coolant filling and engine startup and leak inspection then a final check of engine coolant level.
