What I'm saying is, DON'T immediately unscrew the radiator cap (if so equipped) on an overheated radiator. Stop, open the hood, wait for the "the racket" to stop, THEN very slowly unscrew the overflow tank cap just enough to release the hot water/air pressure, while keeping hands/faces away.
    I was responding to this
    just loosen the cap on the overflow tank enough to release pressure
    But yeah..loosening the radiator cap too soon is never a good idea if overheating is suspected. What happens is that the superheated coolant (say 255 degrees plus) is prevented from boiling and becoming steam only because of the 15 psi or more of pressure it is under. You release that pressure and BAM!...instantaneous steam explosion.

    Agreed.
    If all you are gonna do is give me grief about what I post DON'T READ IT Heh? Have a nice day :-D

    Well they already say "Do not open when hot". Guess you could make them Red, or put another cap under the first one that pops up when the pressure is high and says "What the hell did I just tell you!"

    Wait for it.

    The danger is greater than ever as manufacturers has pushed the normal operating temperature up and up over the years. Current modern vehicles often have normal temp range well exceeding 212 degrees. You could - and probably will - experience a coolant flash if popping the radiator cap on a newer vehicle even when the guage shows it's within the normal range.

    Hopefully the guy is alright but like everyone has stated, not sure how this isn't common knowledge. Worked at a service station in high school and saw this a few times from grown men. That's a lesson you DONT want to learn the hard way.

    My dad was laid up for a week in the hospital and 3 weeks at home when I was about 9 or 10, steam burns at work.
    He was an industrial boiler and furnace repairman. Old pipe gave way.

    Sorry to hear that. I'm convinced that there is no greater physical pain than a severe burn. Had a good 2nd degree burn on my hand when I was younger and the pain was unbelievable. Felt like someone was constantly putting a match out on my skin. This was a very small burn so I couldn't imagine the pain someone must feel with severe burns on a large section of their body.

    Steam burns do hurt like holy hell for a long time.
    No more splitting Uranium for fun and profit, retirement is cool so far....

    With the advent of reliable +150K motors and very few service tasks required under the hood, and "mysterization" of all mechanical things, what you might think is common knowledge isn't really so common anymore. I work on a eight person team, pretty sure only one of them could reliably identify more than one item under the hood any modern car. Some vehicles, the radiator cap isn't so obvious, in facts it's appearance is deliberately minimized so as not to compete with the overflow tank as the obvious place to service the coolant.
