Disappointed,

"it's running hot"
yeah?
"yeah the gauge is in the red"
*looks at gauge one tick mark on the red*

"it's overheating"
yeah? is it boiling over?
"no"
then it's not over heating.

people never cease to amaze me

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
