    Out of curiosity, did you change the engine coolant at 100k miles per Toyota's recommended schedule?

    I was a little late since I purchased the car at 120k. First thing I did was change all the fluids with a full EGR/Intake clean. Transmission fluid was a little dark but everything else looked good, the coolant didn't have signs of corrosion in the engine or inverter. I'm currently at 145k.

    Do we have any testimony from someone who has changed just the impeller only? ......

    There’s been a few reports here, nothing negative IIRC. So far.

    I just changed the impeller.... Only because I dropped the pump as I was reinstalling it.
    And broke the plastic. The original one did spin freely and no cracks.
