Water pump AISIN or OEM Toyota

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.

I wish I knew myself before my overheating probs with the failed first gen water pumps from toyota. Once the new pump was in the engine would work really well when it comes to heating and cooling.

My original lasted 18 years / 249k miles. The replacement one has been in place for almost 2 years / 22k miles.

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.

Mine started going out at ~165k in 2023. 05 Prius. I mostly drive less 5miles at a shot, and it would toss a code if driven much more than that and it was hot

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.
