the exhaust manifold bolt that also supports bracket for a/c compressor and power steering pump broke off in engine block. i was drilling out the old bolt and must have gone to deep. coolant started to slowly leak from bolt hole. how do i fix this problem? this is my only vehicle so i need to fix this asap.

 

You could try getting a stud and coat it with jb wield and screw it in the bolt hole and a nut on it but you wont be able to take the stud out but it might get you threw until you can replace the head but other than that replacing the head is about your only other option
