I guess my experience has taught me that if I build a car/engine with a cooling system that can't keep the coolant at/near thermostat temp, gets hotter in traffic, at lights etc. can't climb a long incline, isn't capable of towing a trailer, and if left that way the temp WILL climb till it pukes .
Is the customer happy if I tell him to pull over every once in a while so it doesn't " overheat " till it pukes , causing potential engine damage/tow.
If the temp keeps creeping up, something is deficient .
In my opinion it overheated once the temp went above the constant thermostat temp expected .
The fact that modern cars have the fan switch come on at 230* doesn't mean it's good for old cars, that only mean the pressure cap works .
Has it overheated ?
In my position, rather than have phone calls, I deliver a vehicle that'll run, no issues .
Imagine telling my racecar driver to slow down if it starts to puke. .rofl
And him telling me to fix the fkn cooling system.lol
