Most of the car mfgrs seem to be using
spring clamps now. They'll automatically maintain constant
pressure on the hose, even if it 'flows' a bit with heat. Of
course, you'll have the same issue; they must be sized properly
for each hose.

are more flexible. Safety wiring them is a good idea also.

Anybody try Oetiker crimp style clamps?
Nothing to unscrew there.

Question
Also, in the past, I have turned the
screw so the slot is parallel to the hose, then
wrapped safety wire through the slot, around the
screw housing and under the threaded end of the
screw.
If
it's a worm clamp bend free end over
screw, will not loosen.
Good Morning,
Question for the group ...
Has anyone experienced a clamp in the
cooling system loosening over time due to
vibration?
Do you safety wire them?
Use a particular type of clamp (such as
Oetiker) to avoid this situation?
What's the recommendation?
