Just wondering if anyone else had this problem before....if i drive my car in the city and let it warm up over 190-200 degree's...when i get home i look at the rad hoses and there both collapsed...it only happens when my car gets hot...then i open the bleeder screw and i get quite a bit of air bleed out...
ive changed the rad hoses...bled the coolant system and it still happens, seems like im getting air into the coolant system...anyone?

 

You could be sucking air into the system from possible leak somewhere. Try changing the radiator cap, then go looking from there if there's still a problem. If you aren't running hot, I don't think I'd worry about it too much.
