I am sure most of the professional mechanics on here know about tamper resistant torx bits like this http://buy1.snapon.com/catalog/item...9&group_ID=285&store=snapon-store&dir=catalog
I went to pull my MAF sensor on the Duramax last night, pulled out my torx bit set and found out none of them worked becasue GM put tamper resistant torx bits on the MAF. It basically has a dimple in the bottom so a regular torx bit will not work. All I had to do was un-do my air box lid and loosen one clamp, then the top of my air box came off with the MAF sensor still attached. I shot it with a dozen or so shots of CRC MAF cleaner, let it dry and then put it back.
Sorry for the rant, it just pissed me off that I need a special torx bit and I had to undo 5 screws instead of two torx bits.
Hey Kevin I should have asked you first! any other special tools I should consider for the '03?
 
get the bits cheap at HF, they have a 100 pc set of tamper resistant type bit drivers for like 5 or 6 bucks.

Ding ding ding.
We have a winner.

Or in a worse case scenario, you can drill the end of a regular one.

I think I'll swing by there at lunch and pic up a set for that price. I'd rather do that than spend any time drilling one. thanks for the tip.
 
on the injection pumps on our M1151's there is a special 5 point torx type security bit with the same little stud in it. A cold chisel makes it into a flat head screw real quick. Not pretty, but gets the job done.
 
Torx bits suck, I don't care who makes the tools Snap On, Matco, Cornwell, Craftsman etc they all suck because the bolt heads round out too easy.

And in this corner... me. I have never, not once, had a Torx screw round on me when i was using the right size. Just gotta clean the crud out of 'em before you start wrenching...

Allen bolts, on the other hand... :shaking:

You need a nice older jeep then. Try taking the windshield brackets off of a yj.

Hm, I'm with Rich (tag-team match fight?). I thought the whoel point of the torx design is that it allows more force to be applied/suspstained due to the star shape. As lon gas it's a tight/clean fit, the grip is fantastic (have 6 corners to grab by).
Every time I've had a problem with one, it's been b/c the socket I had did not really fit the bolt... or said bolt was so stuck that the bit broke.

LE penetrating oil and an impact work great.. start the impact off lightly

Props to Chris M. I could not find the 100 pc for 5-6 bucks but a 7-8 pc for $7.99 at HF during lunch. I just hope the ones on my truck are not metric. doh!

Your just not strong enough.:fuck-you:

If you don't have the right size, grind on the tip til it fits in there nice and tight. Sometimes you may have to force it. No pun intended.
 
Eric, T-20 Tamper proof torx bit for those, If I still have one I'll give it too you.

Seems when my tools were stolen a few years ago that was one of the items that was left, only because it wasn't in a case or on a rail.
Though they did get the T-70 torx that cost me $70 ( try to find an application for that one other than a GM C4500-C5500 rear brake rotor bolts, locktighted with Yellow locktight from the factory, THAT is a big Torx bit and it HAS to be used with a damn good impact, using a ratchet will round out the flutes )
 
Look at the seat mounting bolts on that dmax next. I've got most specialty and security bits/drivers there are, but this one got me. For some reason gm decided it would be a good idea to use reverse torx bolts for the seat mounts. Fawesome. Way to really standardize things guys, mechanics don't have to buy enough one time use tools already.
 
E bits have been around for just as long as the T bits, There are whole socket sets that include both T and E bits and full wrench sets for the E heads.

GM has used E and T head bolt s for years, mostly in applications that the "COMMON USER" need not be messing with. Seats and seat belts being some of these applications. the seats, now that the seat belts are now integrated into the seat, they really don't want just anyone to be fawking with them, especially that those same seats also include side impact air bags. and the seat is now an integral part of the crash protection system.
 
Now they are using Inverted torx plus(5 sided) and tamper rest. torx plus(also 5 sided).

Nothing an improperly used metric socket didn't fix. It was what snappy is referring to, torx plus. I'm glad they don't want people working on their own shit. One more reason why I won't be owning a newer vehicle anytime ever.

It's not so much that, but there is a certain amount of liability on thier part when stuff don't work as designed because Joe Backyard hack decided THIS part didn't need to be in this position or what ever.

That you or anyone "defeated" thier attept to keep you from dismantling the assembly for what ever reason, has pretty much absolved them of any responsibility if fit hits the shan.

Like it or not, it's gonna get worse.

This is why I am not a professional mechanic. Whats the difference between an E-bit and a T-bit? Sorry if its a dumb question.
