    Hi Guys,

    I had my petrol engine water pump replaced yesterday at a local mechanic, as it was leaking coolant. As far as I know the hybrid water pump is fine.
    After about 15-20 minutes of driving, I get a red exclamation mark flash on the dash, followed by "Problem" on the MFD. It happens once, then a few minutes later, 3 more times within a couple of minutes for about 5 seconds at a time. I stopped to try and figure out what it was, couldn't, then continued on and didn't encounter the error again.

    This morning while driving to work, it happened again after about 20 minutes, but this time after the "problem" it gave me an actual error symbol in the left corner of the MFD. It is the symbol for "high coolant temperature".


    I had them install an off-market water pump as they assured me it was just as good quality, and came with the same warranties as a toyota pump, and was overall $150 cheaper.
    Could this be a faulty pump, or have they installed it incorrectly?

    Thanks guys

    perhaps they didn't bleed all the air out, it's bit more difficult than a regular car.

    Right okay, thanks for that.

    I am taking it in tomorrow to get them to look at it, is there anything I should tell them that they need to do?

    This was why I've been using Toyota since I got the car, I've felt that local mechanics just won't be as well versed in the minutiae of the car, and I've been willing to pay a huge premium at Toyota for piece of mind.
    Toyota quoted me $550 for the water pump replacement, and the local dealer did it for $250 with an off-market pump, so I couldn't really justify that.

    can't blame you for that. the trick is finding a mech who is wiling to check toyota service lit and follow it, instead of assuming the prius is the same as any other car. some things are, some things aren't.

    i don't know the process off hand, but there are threads here with complete instructions, or you can try googling youtube.

    I changed the engine water pump myself about a year ago. Quite easy to do. I'm not saying that to brag, just saying any mechanic should be able to do it easily.

    Maybe the aftermarket pump installed is faulty? No odd sounds or leaks in the area where it sits? (left side of engine)

    did you check the fluid level in the radiator?
    are the fans still working?
    I know I would not drive it that way if you blow a head gasket the shop isn't going to fix it for free..

    Most likely it needs coolant and bled. Air pockets can be stubborn to remove.
