Worm gear vs spring type hose clamps?

This. Squeeze, position, release, done.

A light smear of silicone sealant just inside the hose does help constantly leaky hose joints, even with a new hose on a poorly-engineered joint.
 
Thanks for all the replies. I replaced the clamp with another
spring clamp and that solved the leak. The hose was relatively
new but the clamp was original and about 17 years old.

Lots of good tips here. I'm beginning to think that the constant
tension spring clamps are the way to go. Along with a good
set of CTB pliers. I fumbled with those spring clamps for many
years using regular pliers, until I discovered there was
a dedicated tool for those type clamps...

Mubea constant pressure type. Google Mubea(one of the manufacturers of this type of hose clamp.
 
I butter the sealing surfaces with silicone so they'll be easier to take apart. I've learned from spending a lot of time in the past fighting hose connections.
 
I've used 20 year old used spring type clamps harvested from a junkyard. If you are having leakage, I'm wondering if you have some other problem (unless your spring type clamp has rust issues).

This is the clamp I used when I replaced the radiator in my Escort. A stupid mechanic threw out my OE ones when I had the engine replaced, and I did not want to use a worm type clamp on a plastic radiator part:

What i dont like about the Spring type is that they can rust and break. You have to observe and check them from time to time.
And you need these special type of pliers.
But sometimes there is no room for this tool, so its really a hassle to remove the spring type clamps.

I dont like them.

I agree with you, but I will actually reuse the spring clamps if they are easy to get to. I haven't seen this mentioned, but my old boss (with a gazillion years of experience) would use Permatex #2 on reused hoses and then put a new worm clamp on it. This was before the days of plastic radiators, though. I have heard the warnings about using worm clamps on plastic radiators, but you'll be ok if you don't overtighten them. The are a lot of opinions on this issue, but my advice is to use the one that's the easiest to replace, make sure you have a good feel for whether something is too tight or not (if using worm clamps), and to recheck tightness once you go through a few heat cycles on your new hose.
