It's for track cars to help raise the boiling point and increase cooling since they can't run glycol. Whether it does anything or not is up for debate.

ever since we invented all this newfangled technology people just don't have a healthy fear of steam any more.

live steam from a radiator like that will take the flesh right off your bones and boiler explosions will demolish a building just as effectively as dropping a bomb on it.

Engine plant steam is around 400 degrees, from which you can calculate the pressure, and definitely stays invisibly hot long enough.

The fluffy white clouds are not steam. That's condensed water vapor that used to be steam but isn't any more.

When you have a steam leak, you'll know you have a leak somewhere, but it's not necessarily going to be obvious where exactly that leak is.

I have to audit OHSA inspection agencies for my work occasionally, which can entail going with them when they do a checkup of a tower crane. I have to climb 2 or 3 a year, and I hate it. for average length cranes (let's say 30 meter) in my country there is no mandatory safety features when going up, just a ladder in different sections, usually with a steel cage around it. The hardest part is when you get to the top: transitioning from the tower bit with ladders through the rotating hole is usually rather difficult. None of the climbing is done with any sort of equipment to protect you from falling down, it's too much hassle, so you only attach yourself when you're at the top. Climbing back down is scarier than going up.

That had to have been hissing enough to indicate danger. I had a beat up old car in my 20s and even not knowing anything about cars I knew that if I was removing the radiator cap and the pressure didn't let off immediately to just wait until it was done sounding angry. Some things only require a caveman brain

I have successfully brought temps down on an overheating 1960s Chrysler product* by spraying the radiator with water while it was running. I hated shutting the engine down during a bad overheat because the temp will spike even higher once the coolant stops circulating - but there is usually no other choice. An oil change will follow.

the car I'm thinking of from my childhood was either a 1970 Plymouth Fury III or a 1963ish Plymouth... something boring, so at least that part of my memory adds up.

what I remember is the service station guy not waiting until the car had cooked down all the way and very gingerly taking off the radiator cap with a rag. the coolant came out more like a hose stream than a puff of steam, so when he ran like hell he managed not to get burned.

no idea why this would've happened, and I can't imagine that my father remembers this random Saturday decades ago to verify or correct

Even under normal operation conditions, the coolant will still be under pressure. As it's technically a sealed system, once the coolant heats, it's producing pressure. Normal operating temperatures are like, 190-220°F. While it's still very hot, it's not vaporized into a steam, so you get a liquid expulsion instead of steam when you open the system. Or a radiator geyser, I guess.

E: this is where the glycol coolants conversation come in, because it has a higher boiling point, it will remain liquid at temps higher than water can. Then the mechanical pressure of the cap adds to it, allowing it to remain liquid until around 260°F as long as it is under pressure. Remove the mechanical pressure of the cap at that temperature, and you have a rapid change of state from liquid to gas form.

An employee opening microwave popcorn at a huge office I worked at in the early 90s received a similar injury.

They consequently banned microwave popcorn from the break room vending machine.

These weren't the brightest bulbs on the tree, either: there were at least a hundred unattended cubicles, each with their own computer that could log into the system, with no passwords or any security whatsoever. So you could sit down at any randomly, and, say, create fake auto claims as well as a fake tow company and send that fake tow company real checks for towing fake cars after fake accidents.

That place was a real-life Dilbert/Office Space.

Full service gas stations used to top up your oil and coolant during the fill. They aren't really gonna wait around for your engine to cool so they just deal with any back pressure in the very safe use a rag and runaway method you recall. If your engines not super hot it'd usually just spit a bit at you and you could do your thing.

That's a lesson someone learns once. Chances are you saw his first experience with opening a hot radiator. Smart service jockeys just put more fluid in the overflow and call it a day. Customer sees poking and prodding, hears a little trickle from topping up the overflow, and they're happy.

I wouldn't want a gas station jockey loving around under my hood. They're there because they're just starting in the auto field, or flunked their way out of wrenching. It's the walmart greeter of the car world.

Drills can be pretty top heavy with the tower up. It always weirds me out though, when I see a drill with the jacks at the front of the deck and not one in front of the hood.

I haven't seen a full service station since I was a kid. Yeah, there's handicap assistance, but full service isn't really a thing anymore. I have not lived in Oregon or New Jersey, so I don't know what it's like where attendants are required.

Even then, the places I remember from when I was a kid that did have a mechanic do the full service, were usually 2-4 pump stations, 1-2 work bays, on the edge of towns with less than a thousand people where a new stop sign is an event. Usually owned by the mechanic, too.

Noones screwing with your coolant and oil even in NJ or Oregon. For largely the reasons you've mentioned but probably also because modern cars don't tend to leak and consume those fluids as much.

You might convince them to wash your windshield if they're not having a bad day.

Finding the high pressure dry steam leak is a terrifying combination of dowsing and marco polo. You KNOW it's there because it's hissing like a bastard, but the steam stays invisible, so you get your broom and start waggling it at the pipes and fittings until you find the spot where the broom bristles suddenly fall off/start melting. 1200 PSI dry steam acts like the bastard lovechild of a water jet cutter and a oxy-acetylene torch, high enough pressure to just cut through you entirely, with the added insult and injury of massive steam condensation burns.
