    How many pumps on the 3rd Gen Prius ???

    I'm assuming the 3rd Gen Prius has two pumps, one pump for the engine coolant and the other pump for the inverter coolant ???

    Please correct me if I'm wrong, should I preventively replace both of those pumps ???

    Does NutzAboutBolts have videos on this ???

    Below are some videos towards the right direction:​

    Hmmm. I would NOT do preventative maintenance on those items. I would WAIT until those items actually failed.

    Best of luck to you.

    Almost forgot the most important one - the brake booster pump. There'd be no ABS without it...

    Yeah, it will cost you your first-born if it fails.

    There's also electronic pumps that convert your traction battery voltage ~210 V to ~600VAC for driving the electric motors. :eek::confused::eek::confused:
