This ^^^ No retightening / no leaking… much better than worm drive clamps.

Keep / reuse the OE clamps, or find replacements if they’ve been previously discarded.

I use Gates solid surface clamps designed for silicone hoses they work great on rubber hoses as well.

I did a quick Google search and didn't come up with anything on "Gates solid surface clamps". Please elaborate.

I'm guessing your issue with "OE constant tension clamps" isn't that they're "constant tension" but rather that they happened to have been inferior quality constant tension clamps, i.e., you've had trouble with them leaking. Am I mistaken? I can't say I've had any problems with them... but in my lifetime I've probably used fewer hose clamps than you've used in one month.

They were low mileage OE clamps that start leaking mainly. So if they were inferior quality that was what GM and Nissan used.

When I say solid surface, this is what I am talking about. They have a solid band on them that contacts the hose, rather than the normal open worm gear clamps.

Yes, “inferior quality OE” was what I meant to but didn’t type.

I have had nothing but bad luck with the OEM clamps, they always leak and are a pain to install and remove.

That's weird. I have my originals with over 300K miles and I've never had an issue with them leaking. They're a European brand, and hard to get here in the US from industrial sources. The US made Rotoclip versions don't seem as heavy to me, although I've never had radiator hose sizes in hand, only smaller ones.

Yes they are a kind of a pain, to remove install, but I don't have the proper tool either. One of these days, I'll buy the tool.

I own both the pliers and the pliers with the extension cable. Still a pain to work with, especially where GM tended to install them.

The only PITA about the pliers with cable, is that intermittently, the release will stick.
