Yeah I heard higher temps close loop - why do people say 180 ? Is it like an on an off switch or a gradual closing of loop ?
What is a closed loop control system and how does it work?
Closed loop control systems automatically regulate desired states in systems with no human interaction. Learn how they work, pluses and minuses, and use cases.whatis.techtarget.com
Running 225 on the highway would concern me. It should drop on the highway, not go higher.
On my pushrod engine I ran a mr gaskets 180 with a pepboys 3 rom and it pretty much always ran in the 180's.
No. That's only part of it. The "loop" is input to output & back to input in a loop, etc. The inputs can change the outputs & the outputs can change the outputs via some of the inputs. A/F is an output.From what I read a closed loop system takes human intervention out of equation - since the driver does not input any information ( timing , air temps , water temps , A/F ratios ect... ) I would have to say each “ mode “ the car operates in is a closed loop system - during the initial start up of car , until it gets to a predetermined operating point , the car operates in a “ safe mode “ closed loop and ignores the input information from various sensors and operates in a pre-programmed setting from the ECU . Does this sound correct ?
I wouldn't think too much of it.No sudden swings in temp - I burped like described - a new radiator would not hurt anything and mine may be too old anyway - but .... why still perplexed as why did the engineers at Ford put 270 as danger ?

In open loop, the outputs cannot change the outputs, i.e. the loop is "broken" or open.
Negative feedback in an amplifier would be an example of a continuously operating closed loop system.
These don’t have a spring .It has new lower hose - are they suppose to have a spring inside to prevent collapse ? How do you check for collapse under high rpm
You are going in the right direction replacing the old radiator.
also check to make sure the lower hose is not collapsing at higher rpms.
the 270 mark on the stock gauge is just the engineers way of inaccurately say'n 'your done'.
