    So it looks like it's coming from in front of the fan just below the thing that says hybrid synergy drive and has a silver lid on it the inverter more than likely you're going to have to undo the 10 mm bolts on your fan or fans and lean them back You can push them back a little bit so you can get a view in there if it's pissing water that means it's under pressure so it's got to be coming from the radiator so more than likely the radiator is going to have to come out The plastic tank that holds coolant is not under pressure so it wouldn't usually piss out of there it could be cracked and leak but it wouldn't squirt like it was under pressure pissing or streams is generally under pressure it'll be coming from the aluminum radiator assembly.

    That's near the location of the radiator cap... I bet once the engine is cold again you can simply replace the radiator cap and top it off with coolant and it'll be problem solved.

    It’s the one next to the hybrid silver thing that’s just pushing it all out

    It’s more like it’s just rapidly draining also if I did have to replace the radiator how much would that cost do you think?

    If you go out and look at a car at a junkyard or see your radiator at a shop for this car you'll see it's two radiators if you will anyway regardless of all that I have three laying here and I got them all for nothing and anytime I'm over at LKQ I can grab another one I just usually don't because these things almost never get replaced or it is very rare other than a front accident.

    All you're gonna get here are guesses. You, and only you can find the leak.
