Upper Rad hose popped off radiator inlet 5.2?

I was driving home from work yesterday and 10 minutes into my drive I noticed the temp gauge was acting funny, then started smelling coolant, then the smoke started coming out from the hood...I was able to get off the highway and into a parking lot.

Opened the hood and discovered the upper radiator hose (with worm clamp still attached snugly onto the hose) had slipped off the upper radiator inlet tube. No real idea how this happen? Roughly 3,000 miles ago I replaced the entire cooling system: Radiator, water pump, timing chain cover gasket, upper/lower hoses, used OEM thermostat. Everything has been running great with no issues until now?

I know that hose clamp was on there tight bc I am ocd about tightening things and I had to loosen it a bunch to get it re-attached so I could limp it home. From my google research I have read that a bad radiator cap (also new) could cause too much pressure, possibly blowing off the hose, but this whole thing is strange to me?

Any ideas?

Maybe this brings up the great spring clamp vs worm clamp debate? The inlet tube on the radiator is plastic, I guess there is a possibility that worm clamp un-seated due to exspansion/contraction? I know I am over thinking this entire thing and only time/more miles will tell but its just odd to me...

KNOW THAT FEELING....
but mine got reallllly hot before popping off/almost in the red, but was two blocks from home.
luckily I was already home when the hose blew off.

Was it overheating prior to this?

The cheap worm drive hose clamps loosen up. All of them, every time. Use spring clamps, NAPA has them. They are more expensive.

Funny, same thing happened to me Tuesday night about 2 miles from home. The hose HAD the factory spring clamp on there and sure as hell it came off. Put a GOOD quality hose clamp on there and kept the spring clamp as a back up.

Thanks for all the replies, spring clamps it is then. This makes me mad because I replaced every oem spring clamp with a worm style when I did all of the above repairs because I read somewhere that recommended them....live and learn.

Well when I said spring clamp, I meant spring loaded t-bolt clamps. I would use t-bolt clamps over those idiotic stock clamps. You can get t-bolt clamps with or without spring loading. Either would be fine.

For anyone that might replace theirs, rockauto has those t-bolt clamps for half of what the auto parts places want..
