I doubt you hurt anything.
What are the choices anyway ..
it's either fix alt and belt, check/service/fill coolant and see how she
acts and works .....
or takebigger things apart.

the heads have several leak modes ....they seldon to to immediate
significant external leaks in my experience...
'never' even.

fresh engine ...might be more sensitive to getting a little hot,
compared to one well worn in with 150K+ miles on it.

the Blue Pressure cap ..those can not be counted on to release pressure.
I have seen the pressure coolant bottle puffed up badly from high
cooling system pressure ..
the blue cap sure never relieved pressure like normal coolant pressure
caps used to.

you might change the oil .

The gauge was rising quickly before I shut it off in a safe location. Opened up engine compartment, I could hear water gurgling but nothing was spewing out anywhere and it had not hit a temp that caused the coolant to go from expansion tank to overflow tank.
