Torx rotors screws stuck on 96 Volvo 850

Get a torx driver that fits. (1)Then, as you exert counterclockwise torque, lightly tap the upper end of the torx driver with a small, steel hammer. (2)If the screwheads are accessible, it'd be wise time to purchase a tiny, but GOOD pair of vice grips (I have a pair ~3 1/2 inches long made by ViceGrip)--I've used them for such many times over the years. You'll wonder how you ever got by w/out them. s

Try a 3mm Allen key to remove the rotor if stuck use a good pair of vise grips to loosen Glenn

Torx heads come in several different sizes, and you need the correct bit to fit a particular one. Yours are probably T-25 or T-40. Maybe you are using a T-15 screwdriver?

Glenn indicates it is an Allen head, in which case any Torx will just chew it up. A piece of plumber's putty pressed lightly against the head will show which it is for sure, but I think Glenn already knows :-)

Volvo uses 'torx' screws???

I have a feeling they are allen head, could be wrong though. Non of the older Volvos I used to own were cursed with torx.

Might they even have been metric Allens? It wouldnt surprise me. And for that application, are they right hand or left hand threads? Just a thought. I know little or nothing about Volvos...

(Friend of mine met an old acquaintance on the plane, who wanted him to come home with him, have a drink,and take a look at his wife's 'Vulva'. Friend was excited until he saw that darn little Swedish car parked in the driveway;>) ((a true story, mostly))

I haven't seen them on a Volvo yet, Saabs are full of them though. So long as you have the right bits they're actually great, I have yet to ever strip one out and the screw will usually stay on the end of the bit well enough to feed it into a tight space.

Yes. (Whether they use them in the distributor, I don't know yet, though.)

Fair point - although the OP clearly thought that they were torx!

However, I've just looked at a photo of a rotor arm in my Haynes 70-series manual, and the screws look distinctly like Allen screws - so I guess the

850 had those too.

That, or Haynes is using the same picture they have used for the last 20 years......

..........or a generic picture from another car entirely.

Not that its the same, but i have seen both hex head and torx head caliper pins on taurus of the same vintage. I about got caught using the wrong tool for the job because of this. DOn't know if it was a factory thing or after market parts. It pays to check

Jeeps are full of them. The teeth rot on them with the slightest bit of a paint chip so once used, they strip out extremely easily. Same for sizing. The paint thickness won't allow the proper sized bit to fit, so folks use one size too big, the paint just crushes and bingo, another one stripped. So to use them you have to chip the paint out which rots them....

At least they do drill out easily because the hole centers the drill bit nicely...

When I last changed the rotor on my 850, the old one was held by Torx screws, the new one with Allen screws. So I figure it might be either, depending on the manufacturer of the rotor.
