How can i get an oil drain plug off that has been rounded/stripped?

Its rounded on the head of the bolt. I've tried Gator Grip, Vice Grips with no luck. Its on there VERY tight.How can i get an oil drain plug off that has been rounded/stripped?
Use a ';easy out'; . You first drill a small hole in the bolt.(you may want to use a dremel to grind a spot in the exact middle so you dont get it off center)then you drill a larger hole with the size needed for the easy out.(it should have the bolt size/drill size requirements on the package) then after the drilling you screw the easy out into the bolt and when you remove it ,it locks the bolt and takes it out with it.Be careful not to drill all the way through. It would get real messy)How can i get an oil drain plug off that has been rounded/stripped?
using a hacksaw blade cut a straight line across the head of the bolt for a large flat tip screw driver, the use a manual impact driver to loosen the bolt
i have in the past,use a small chisel and on the edge of the plug to remove these,just tap lightly in the counter clockwise direction
If its a metal plug and metal pan, away from plastics, hoses, wires, etc... use a propane torch or a heat air gun to heat the plug area. Then spray it with penetrant oil (WD40) and then crack it out with vice grips.
pipe wrench or beat a smaller socken on it with a hammer
A pipe wrench will turn any bolt.
whatever means you use, dont try to use tourque to turn it, instead use a hammer to tap it loose. next time, do not overtighten it, or kick the persons *** who put a stripped plug back in.
They have special sockets available at most auto parts store that remove rounded bolts. Just ask they'll know what to give you.
vice grips would work it you put a longer handle on for more leverage, or anything with a long handle...i recomend a pipe wrench....and you can extend that handle by slipping a piece of pipe over the end of that handle!
Buy a new plug and take car somewhere to have oil changed. I am sure they will be able to remove plug and put new one in. Should not cost anything extra. Then you can change it yourself next time.
two ways first you can drill it tap it insert a left hand thread and it should screw out





second .quicker and less bother .. cut the top off a bolt and weld the top of it to the stump of the old plug then it will unscrew
