    Was it a flush or a drain and fill?

    I have heard of people having issues after coolant flush.

    The question is why they even removed those when the drain petcock on the radiator is like a foot away from those hoses.

    Glad you got it figured out though. Did you wait till the engine was cold (to avoid steam explosion) and then check the coolant level in the actual radiator? The coolant should be up to the neck. Also, keep an eye on the coolant reservoir for a few days, sometimes there is air that burps it’s way out and then the radiator pulls coolant from the reservoir tank.

    Yes it was cold was not touching it while it was hot, i left the TRD skid plate off and think i will leave it off for a week or so.

    That skid plate hides leaks.

    what about the Pecock at the bottom of the radiator could just be seeping out of that

    agreed they’re only two things you need to remove,, the radiator cap and the radiator Petcock at the bottom of the radiator that’s it. I just did my 2011 SR5 last month and it was a gallon and a half of fluid that came out out of the radiator
