i was in the process of changing out the thermostat and snapped the head on one of the bolts any ideas on what to do  
      
                        
                      
                             
      
      
            
            
        vice grips if there's anything left of the shank,  or drill it & easy out it.  ensure you center punch the bolt before you drill cause if you're crooked, heli-coils are damn expensive!
good luck
      
                        
                      
                             
      
            
            
        If you take a small nut and spot weld it to whats left and turn it out. 
      
                        
                      
                             
      
            
            
        They make a socket that has a left hand thread on the inside for grabbing the shaft of the bolt to unthread it. Much easier then a left hand drill bit.
