How would i check/bleed the air out if there is any mate?! Assming runnign the car with the pressure cap off? is so done that

Cheers for the advice.

Ermmm not too sure on the bottom hose if im honest tis in the garage now so cant really check, seems as if theres not enuff water getting to the head as obviously the water cools it so without enuff the temp would go high as thats where the sensor is, theres no aparent leaks from the head gasket either from what i can see.
