how to bleed the air out after draining the coolant

[Amir]

Hi everyone. i got a zx2r c model
i hv no idea wat bots to open to bleed the air out. after draining the coolant... i looked up on the owners manual that is uploaded on this website but it hasn't been scaned really well so can't really see the second bolt... whic is the cylinder head...
i was wondering if someone can upload a picture or something... dat will show which bolts to open...

oh besides my coolant is really brown... is dat bad??? like permenantly bad?

i would greatly appreciate your help

U should have a small bolt above the water pump...
Also u don't need to bleed the air out once u drain it and re fill squeeze along he rubber hose to push any air out.
Once filled up start and let the bike run and warm up to allow the thermo to kick in leave the rad cap off and watch for the flow over the top of the rad this will also flush any air out, top up if needed.
The brown coolant no idea mines only ever come out green or red same as it went in...

Brown coolant is a sign of rust, & yes there are metal components in the radiator
