When I drove a Volvo I just did a belt and water pump every year. OE Aisin one every time.
Aisin is what my shop used when mine started to die at 140k. No problems so far at 150k
Go for Aisin, Toyota just repackages same pump so skip the brand tax.
Aisin pump $67 on rockauto. I know they make a ton of Toyota OEM water pumps, not sure about this specific model.
Currently running a fvp, which is just a gmb, and it works great.
I'd swap them out for multi-layer steel gaskets and new head bolts. Given the engine is in good order and hasn't had a gasket failure yet I'd say you'd be fine skipping the head decking and just install the new gaskets after a good cleaning.
Aisin is the maker of Toyota water pumps.
The fel pro gasket set and head bolts + head bolt tool will be close to 300 and then you'll need RTV sealant. Another probably 200 for the Aisin water pump.
I used the same kit on my tl and the water pump started leaking 2 years in.
I went with a aisin kit and at the 2 year mark the water pump went.
