    I have coolant disappearing out of my reservoir tank thing, however there isn't any visible signs of a leak on any of the hoses or the ground.

    Car runs like a raped ape...doesnt get above the half point on the temp gauge or anything out of the ordinary.

    This means??????

    Run a pressure ck on it. U can get a loaner tool for it at the parts store
    If the pressure leaks down and you see no fluid it most likely means you popped a head gasket at the least.
    As you arent seeing any fluid it is most likely going out the tail pipes as vapor......

    Also do the pressure test with the car up to temp.

    the car would overheat if you popped a head gasket. and the oil would be milky.

    I've been reading different things, but I believe it may be the non OEM rad hose clamps...soo Im gonna run to ford tomorrow and try and get some.

    Broken non oem hose clamp under coolant reservoir...guess maybe I had overtightened it and stripped it, replaced it with the oem one I had just found, hopefully that was the issue.

    Tap uh talk app post...

    Also check, as I've been having mysteriously disappearing coolant, that your rad cap doesn't have a cracked gasket.... :facepalm: That evaporating vapor will make your level lower...

    i double checked that before taking her to work...might go for a spirited drive after work in the am to see if I fixed it by replacing that busted non oem clamp.

    not always... if the head gasket failure is between a cylinder and water jacket, it will burn coolant, causing the coolant level to go low which is the actual cause of the over heating. if he is keeping a close enough eye on it, it could just loose coolant and never get far enough for the over heating.

    as far as non oem clamp, if they're tightened propperly, they work just as well or better... but if it's a low quality one, they really are easy to strip out.. hopefully that's all your problem is.. the autozone pressure checker will likely not come with the propper fitting for the degas bottle.

    looks like it was stripped and wasn only tightened to be snug...so I replaced it. I hope that is what it is...kinda wanted to work on other things... like a blower or something fun.

    NOt always if the water is enter the combustion chamber it can go thru and out the tail pipe w/o overheating or milky oilll Of course left alone long enuf it will cause an overheat issue

    Does your car have an oil cooler? I have the same coolant disappearance issue your describing. I was told to check that. Just an idea if yours has it. Mine leaking is so far in between having to fill it up, I havent decided to mess with it.
