Toyota 16100-29146 Water Pump

To remove the water pump, first disconnect the cable from the negative terminal of the battery. Next, drain the cooling system. Remove the engine drivebelt and the alternator. Proceed by removing the bolts that secure the water pump and carefully take it out, noting the length and position of the bolts for reinstallation. Thoroughly clean all sealing surfaces and remove the O-ring from the groove in the timing chain cover. To install, begin by placing a new O-ring in the timing chain cover and positioning the water pump in place. Install the bolts in their original positions and tighten them to the specified torque. Finally, reinstall the remaining parts in the reverse order of removal. Refill the system and check for any issues with the water pump.
