Does the clamp look anything like this?With adjustable pliers. Not with any special tool.
I don't really have a problem removing and installing those pinch clamp with those.
Do you think the pinch clamp could be worn?

This.Try one of these Gates specialty clamps designed for hard to seal leaky hoses.

Those are a constant tension hose clamps. They can lose their tension over time especially if they've been expanded out too far. The way they work is they expand and contract depending on what the hose is doing. Rubber hoses will shrink when they get cold and the clamp will shrink with it. You can replace it with a worn clamp but worm clamps need to be monitored all the time because they are not constant tension.yes that's the one

I highly doubt it. I think there's a possibility you need a new clamp.I was wondering whether a blockage (somewhere at the thermostat housing area) could somehow increase the pressure in that area?
you have overlooked a possibility.
The hose was the problem. And the new hose is a problem.
It's the clamp, man. Just put a new clamp on it and quit overthinking it. You should, as a habit, almost always pair new hoses with new clamps, unless the car is only a year or two old. A worm-drive (aka a few) type clamp will work fine. Been using them for almost 30 years and never once have they given me any issues with coming loose or anything bizarre that people here seem concerned with. Make your life easy, though, and use a nut driver or a 1/4" ratchet instead of a screwdriver to tighten. Much less headache than a flathead. Just tighten them to tight and stop, you don't have to crank down on them.I'm about to go crazy.

Technically, you can unscrew a screw clamp all the way, open it up, and fit it around the hose without disconnecting the hose, then reassemble the clamp and tighten it down in the proper place on the neck/hose junction. Just move the spring clamp out of the way, and be careful not to kink the band on the screw clamp. No hose disconnect, no coolant loss or mess, and you'll know pretty quickly if it was the issue or not.I hear you.
The problem is if it leaks again, it's going to create another mess.
Draining coolant. Buying more coolant. Round and round we go.

A new clamp didn't make any difference, hmmm.,,
NAPA Know HowBut I'm going to give NAPA a call to see if they have a 1.5 inch constant tension clamp, if they have it I'll give that a try first.
How do you expand this type of clamp out too far?Those are a constant tension hose clamps. They can lose their tension over time especially if they've been expanded out too far.
