How do I remove this bolt from my smog pump!!!

The bottom one came right off and the top one is satan himself. I have tried everything. It is stripped beyond all hope so I drilled a slot into it to use a flathead screw driver but It just won't budge. Can I just cut around it with my dremel or can I drill it out. Here is a pick of the bolt that I am talking about.

I am about ready to do that but I wanted to keep the bracket in one piece. Oh well, I geuss I can always replace it if I were to ever put the stuff back on. I am pretty sure I can pass the sniffer without it (I have a cat). I don't have smog where the car is registered but may when I move after school.

I'd set the a/c compressor to the side if ya can and get at it with some vise-grips... spray some PB blaster in there too at 2-3 hour intervals for a day or so and I bet it'll turn loose. Whatever you do, DO NOT do any hot wrenching on it. Those acessory brackets are aluminum and, well, you get the idea.

I am not sure what hot wrenching is but I am pretty sure that I am not doing that. Just drilling it out. I may try to get at it with vice grips.

Just do like you originally thought. Get a dremel with a cutoff wheel and cut the head of the bolt off.

Hot wrenching is where you use a torch to heat a nut or bolt that has siezed. Heating the nut or bolt will help to break it loose, but you cannot use this method where aluminum is involved. One of the problems with steel bolts in aluminum is that they expand and contract at diffent rates often causing the bolts to sieze (this is why you use copper anti-sieze compound on spark plugs that are going into aluminum heads). Even if you can twist the thing outta there, if it's siezed that badly by forcing it out half the threads are probably gonna come with it anyhow. Just cut the thing off flush with the pump and if you really want that bolt out, weld a nut onto the end of it and then use your ratchet on it.

If I cut it off flush will that be enough for the pump to slide out? Would I have to drill into it a bit to clear the bolt from the bracket?

Make sure you use the right torx the first time, 2 of them will fit, a small one, and a big one. Thats a mistake alot of people make.

What I did.....This is a VW trick.

Get a big hammer and a chisel(sp) and hit the head of the bolt counter-clockwise. Eventually, it should break loose.

An air chisel works great too. We had one when I worked at Lube Time to break loose drain plugs that were too tight. We called it "The Persuader"

Usually when drain plugs are too tight, they internally strip the pan.

Well I got it out. I took off the AC compressor and set it aside and was able to grab it with some vice grips. I did damage the bracket (trying to drill it out) but the threads are okay and can be reused if I ever put it back on. Thanks for all of your help. I am now trying to find a belt that will fit. I hear the 968K6 is the one to get. I had a 967K6 belt that was to short by a couple of inches.
