Hood hinges

My hood hinges are getting discolored due to last summer's heat, but I have not really gotten around to getting them touched up. I had some time today and took off the cowl piece to repaint, and tried removed the hood hinges also. Well I broke 2 torx bits and about 1/4th a can of PB blaster on the bolts and still the hinges are firmly in place. Anyone have any sure fire way to get these off? I don't trust heating them up if I can avoid it, unless it is 100% safe(well as safe as using a propane torch is).

Use an EZ-out. The hood hinge bolts should be 5/16". EZ-outs and PB blaster should do the trick. If you can find a penetrator called "Aero-Kroil" that's like PB blaster on steroids, penetrates down to 1-millionth of an inch. I always use that and it always gets the rusty-rounded torx bolts out.

another tip on these torx bits it to use a small flathead or a skinny knife blade or a pick, something to get in the tip and clean all the paint off from in there. If you get it to bare steel inside the hole, you're bit will sometimes seat twice as far into the socket on the bolt.

Always try to get to the back of it as well. If you can see the bottom of it under the hood, spray the threads and maybe apply some heat to it.

I have gotten the broke head of the torx bits out of the bolt head, the bolt head won't turn. I can get 3 of the bolts from the bottom to apply heat which I may do, but that still leaves the 2 bolts that hold the hinge to the Jeep body I cannot get to the underside. Will it damage/warp the metal or paint if I heat the bolt heads?

probably. you dont want to heat the bolt, you want to heat the sleeve to expand it off the bolt.

See if chipping the paint out of the bolt will allow the torx to sink in further and grab. Otherwise, you may have to drill down through the head until the head pops off. Then drill out the hole and re-tap it for another bolt. I've also seen where the heads were drilled off then new bolts were used with a nut and a lockwasher on the underside.

See if there is any was possible to get a squirt of spray under them. Maybe be removing the cowl? wheel well? not sure but there has to be somewhere to get to them.

May not work but look at this idea to... someone told me once that I could use a flat disc on a die grinder and grind a flat groove across the head down into it. Then use a really large flathead bit on an impact gun.

Or, forget the whole idea and tape off around them to get a fresh coat of paint on there.

Yeah that is the plan I think to just tape it off and spray it, just a lot of taping off... But that is the way I think. Haha
