Just changed the coolant on my KH Verada 3.5 V6 and I was wondering if there is a bleed screw on the system?

Cheers!

Not a direct answer, but I remove the coolant hose from the front of the throttle body. Replace when there is a steady flow of coolant (when refilling radiator).

I'm not sure how you changed your coolant without removing any drain plugs but as a general guide there are two plugs on either side of the main block. They are 14mm in diameter and, at the front of the engine block, are located towards the drivers side and at the back they are located towards the passenger side.

Otherwise the radiator has two bleed valves on the bottom (left & right) and, as per above, the throttle body also has coolant hoses that can be removed to drain coolant out of the throttle body.

he is talking about bleeding the system after refilling to remove air trapped. some cars have a screw at the top of the system where air collects, so as you let it idle and warm up it expells the air. i always just leave cap off as it idles and add coolant if necessary, once the coolant starts to swell in the spout replace the cap. i have found that after the first heat up/cool down, if there is air it is expelled to the expansion tank, then as the car cools it draws back coolant. always check the expansion tank level after.

Thats what I was getting at! But thanks to the others that answered too.
Thought this might have been the case so I did what you mentioned earlier and it worked a treat.
