exactly right.

but also remember to put the temp slide to HOT , leave the car idling until the thermo fan switches on TWICE and top up the coolant as it drops in level.
after twice most air would of worked its way out. replace cap and drive as normal , and check your overflow resevoir in the next few days , it may need a top up.
