The last two Hondas I worked on where push on style hoses like this with no clamps because they were low pressure systems.
Both had pressure caps and I was asked specifically which year when at the parts counter because they apparently changed them between model years for the refresh.
I’m a mechanic and have been one for 15 years. As someone else said there’s no clamp on the hose. That should give you a clue.
Yes, SOME cars are different, especially newer ones that self burp air out of the system. But 90% of vehicles, do not have pressurized overflow lines.
The springs in radiator caps are there TO allow air and coolant to escape to the overflow tanks when the rest of the system is pressurized.
