    I finally got it, i ended up replacing just the thermostat, the pump was in good shape.

    I just drained and filled. Hardly noticed the difference between the new and old fluid. There's a whole lot of unknowns about the maintenance of this vehicle, so in good faith, this was probably for the best.

    The leaking or evidence thereof was on the thermostat. I actually discovered why it was leaking there to begin with the gasket edge of the block where it makes was not exactly smooth. I smoothed it as best I could with a non - scarring pad. For good measure I used high tack gasket sealant (a light coat, heavier near the uneven area). I most definitely either got a refurbished pump using an OEM stamped pump housing or an all out fake. These eBay sellers went to Great lengths to make it look genuine. There were no QR codes, barcodes, serial numbers or anything, just Toyota Aisin stamped....

    It will be returned. The thermostat was fake as well but comparing the two they were so close to being the same down to every detail i decided to use it. Pump is easier to get at if it does fail later. Also to note I spun the pump by hand new and old....it felt the same as I felt each magnet pulse. It very well could have been used as a very good pump but I'm not going to trust it. Every single detail on the thermostat was spot on. It's almost like it was the exact same part except no Toyota markings...

    Yeah, I feel like those alone were the worst of the problem. I also may have misread the scantool P0300 not P3000. Big difference, idk ill check the scantool again sometime and see what shows up.
