Water pump AISIN or OEM FORD

Otherwise, given the information you've shared, I think replacing the pump is a good idea.

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'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.

I had a 2017 GT… here are common issues that I also ended up having:

Water pump went out at 60k

AC started to struggle, especially on hot days, around 70k miles

Get the OEM water pump, I had no luck with aftermarket Aishin. They leaked almost immediately.

Replaced with Asin, failed in 7k miles. The propeller disintegrated on the second one.

Only thing that left me stranded was the water pump. I thought I had a squeaking belt for the week leading up to it. I was wrong lol

2006 Ford Explorer with the V6. Somehow went through four water pumps in one year. Made of the cheapest ticky tacky bullshit.
