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

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?
