• Q: How to Service and Repair a Water Pump on 2001 Toyota Tacoma?

  A: Professional service of the water pump begins with timing belt removal followed by connections to both water inlet and thermostat. The No.2 oil cooler hose must be disconnected from the water pump before you can remove the water pump by unbolt its 7 fasteners and using a pry bar to extract it. First check if coolants are leaking from the drain hole of the water pump. Replace the water pump and timing belt in case of leakage detection. The water pump bearing should be checked by examining the pulley rotation for smoothness and absence of noise before obtaining a new water pump if needed. Replace the fan by removing its 4 nuts and checking for damage and silicon oil leaks as well as performing any necessary replacement before reinstalling the fan with torques of 7.4 Nm (75 kgf-cm, 65 inch lbs.). The smooth operation of the fan pulley bracket must be inspected with a replacement if required and all timing belt elements need to be checked. The installation process demands that you eliminate all old packing (FIPG) materials with caution while maintaining the surfaces between the water pump and cylinder block free from oil exposure. A razor blade along with a gasket scraper should be used to scrape off all old packing material from gasket surfaces and the sealing groove while cleaning all parts thoroughly to remove loose debris followed by cleaning each sealing surface with a non-residual solvent. Apply seal packing material (Part No. 08826-00100 or equivalent) into the water pump groove through a 2 - 3 mm (0.08 - 0.12 inch) nozzle opening. Reinstall all parts within 5 minutes, otherwise remove the material and reapply it. Replace the water pump with its seven bolts while torquing them to 20 Nm (200 kgf-cm, 14 ft. lbs.). Once the nozzle is detached from the tube, reinstall the cap. The last step includes installation of the timing belt together with the thermostat and water inlet and attachment of the No.2 oil cooler hose.
