Type in the model and year, sometimes vin number, and then the part you are looking for.
I don't understand how that is hard? Or take the info to Toyota....

Seems like you need the coolant pump, and coolant.
Shouldn't hurt to get the thermostat also.

Trying to find the proper thing I want on Toyota web sites is very complicated. That said, unless there's a lot of other things I need that I don't know about, I can get the proper water pump assembly from a local Toyota for $265, which is certainly better than $500. But I don't know if that is all I need, or if I also need this and that and the other.

Anyone know with a fair amount of certainty if the water pump assembly is the totality of what I need for the pump? (ie not fluid or thermostat.) It is listed as the part number I was expecting.
