Broken Coolent Bleeder Vavle

[jay561]

well i posted in the 240 section not knowing about this section, but heres the back round my 93 240 was over heating so i changed all this and it still over heats radiator, water pump, thermo, coolent temp sensor, resovour tank, and radiator cap. then it still over heated and some one told me to bleed the system with the beelder bolt, i did and it worked FOR AWHILE then it started to heat up and when i was losing the bolt a bit it just snaped! so now i have the bolt head and the bolt half way threaded in, how should i go about trying to get it out? and what the hell could still be wrong with my cooling system?? o ya my fans both work also

probobly have to drill and tap it, the metal is soft because the intake mani is aluminum. make sure you dont open that when its hot

methods to try in this order1)vise grips on bolt shaft or eraser head if its sunk in.2)drill tiny hole in center of bolt shaft and use extractor3)drill hole out and install helicoil
