Im changing the water pump on my explorer. As i was unscrewing the bolts one of the heads to the bolt wore out and now its really hard to take out and its giving me a headache. any ideas of what i should do to take it out?
Drive a smaller size 12 point socket onto it.
use minny vice grips it slow or grind head off take rest of bolts out pull water pump an alot more bolt to grab with vice grips an turn out a little lube blaster an screw back in an walk it out like that till all the way out an get a new bolt
If there's tail of the screw still out ,use an alligator clamp wrench . clamp it as hard as you can ,then spray some WD-40 waite 5 minutes and then try to open it . If it brake from inside the trade ,there's no way except drill small size hole than the screw, in the screw and then use left turn opener wrench (buy it from auto zone or home depot) direction of the use it's on the Package .It is a left turn traded screw with square end . After you get ride of that screw for re installation use high temperature grease and apply to the tread ,make sure pump cap it's not deform ,if is deform buy new and apply grease to the washer gasket before install .
