youll have to pump the hoses a lot with your hands (prefably wrapped ina towel or summink coz they get VERY hot) also youre suposed to let her run up to the point when its just about to boil out of the header tank, then quickly put the cap on n kill the engine, then let it all buble about etc for a sec... whe the level starts to drop again slowly open the cap a bit to let the air out, dont let the (VERY VERY HOT) water escape tho if you can help it...

keep repeating this till no more air comes out then just make sure the water level is always kept topped up (as the water cools the level will get lower)

you may have to repeat this process LOTS of times

i spent most of the morning saturday bleeding mine as its a pain in the arse to do sometimes, and i kept making mistakes n letting all the fookin water boil out
