Yesterday night while rushing around to try and get a card for the mother at 10pm ( yes i left it late lol ) i noticed the temp guage was around 3quater's up thought it was strange as never seen it above half before, but carried on driving droped my gf off home left the car running while i said the usuall cya tomoz and what not and then the red temp light came on. So car straight off bonnet up and noticed this pipe was semi together.

Connected back together and still had high temp around 75-80% so drove to chippy had something to eat so car was off for about 20min's tunred car on and it rose to about 70% pritty quick what problem could this be ?
