2000 Toyota Avalon Parts Questions & Experts Answers

• Q: How to service and repair the water pump on 2000 Toyota Avalon?

  A: The repair and servicing of a water pump should start with coolant draining from the engine. Before extracting the water pump remove the timing belt, camshaft timing pulleys and No.2 idler pulley and No.3 timing belt cover by taking out the four bolts and two nuts along with the gasket. The water pump should undergo inspection of the drain hole for coolant leakage; when leakage is detected the water pump replacement becomes necessary. Check the water pump bearing movement by rotating the pulley because a faulty bearing requires a water pump replacement. Secure the water pump with a new gasket through installation of 4 bolts and 2 nuts to a torque strength of 8 Nm (80 kgf.cm, 69 inch lbs.) while keeping the gasket free of oil residue. The installation process must follow with the No.3 timing belt cover accompanied by the No.2 idler pulley and the camshaft timing pulleys and timing belt. Check engine function by adding coolant before starting the system then verify leakages and gauge engine coolant levels.
