as title peeps this is a nightmare i can not get all the air out of this punto.its a 1.2 8v (2000)i put a head on it bout 3 weeks ago and sorted some other problems on it.the car runs fine i did a 100 mile stint in it a couple of nights ago to make sure it was fine and i had no probs at all however i cant get rid of this water noise from the matrix.when i put the head on i had it skimmed put new bolts on it as well.i have tried bleeding it everyway i can think of and i cant get the airlocks in the matrix out.it is not blocked i have run a hose through it and i have good heaters in it all the time.i have tried the guide to no avail.i am a mechanic and cant believe this is beating me i have done a sniff test and there is no prob with that it is not building up any pressure.sorry if i have rambled on but i am at my wits end with this.any suggestions?

They're a nightmare tbh, I just keep re-bleeding mine after every journey till it's sorted.

Try and park it with the nose of the car higher, this raises the coolant resoviour above the rear bleed point helping you get more air out.

ive had it right up at the front with no joy.thanks for the advice though.looking under the dash it looks like the matrix is actually quite a bit higher than the bleed points WTF is that all about?
