P261B

This is more of a rant...

Little background.... I usually buy a used(fix upper) Prius every year in anticipation of of my dispatch assignment for work, and sell it when my assignment ends so I won't put extra mileage on my personal vehicle..
So back in March I purchased a fix upper 2010 Prius that have a blown head gasket, and after replaced the head gasket and all the maintenance for it, I then drove this vehicle for couple of hundred miles and decided to change engine oil and drain and refill the coolant again to get whatever may till trapped inside the motor out..

An unfortunate event happened yesterday, during the drain and refill system coolant I somehow left off the spring clamp to return hose from thermostat to radiator and it blew off while I was driving on highway... pulled off to the nearest parking lot off ramp, put everything back together and drove to the nearest parts store for coolant. I wasn't thinking and should not have drove it with coolant loss, and now I have P261B code and engine is over heating... I can hear the water pump ran, but have issue with getting air out of system somehow...

Picking up a new water pump tomorrow, just in case water pump burned up while drove it to auto parts store...

Very frustrated at the moment, it was a perfect running vehicle until radiator hose blew off. A lesson learned...

Always double check your work after completing, NO MATTER WHAT!

Got the water pump out, and propeller is ceased inside. I tried to pull it out to get a better look at this, and only part of the top came out with a forcefully pull.. LOL

This was a perfectly working pump when I installed weeks ago, just to show what heat and lacking of fluid can do to this thing in short period of time...

Drove a hilly highway 90% and couple of stops, the temperature average 195° ( constantly) with 199°(up hill) being high and 188°(down hill) low...

One question tho, I checked the hose that below off couple of days ago the one between thermostat and radiator. It feels cool comparing to all other hoses, engine coolant reservoir is pretty warm and all hose to and from are warm, I can touch it with my bare hand so it's not hot, hot..

My question is... is this normal?
I remember that hose being pretty warm before, I should have checked the thermostat but didn't get to...
