Torx rotors screws stuck on 96 Volvo 850

    In trying to replace the distributor cap and rotor I ran into a problem
    getting the torx screws out that hold the rotor on. They won't budge.
    I'm pretty sure it's the original rotor on there because it's really
    worn out so I'm confident that it's causing my gas mileage problem.

    I tried using a torx rachet socket and a torx screwdriver and they both
    feel like there are a little too small for the bolts. I'm afraid of
    stripping the screws if I try too hard. I sprayed some bolt lossener
    on them but this didn't help. What else can I do?

    Thanks,

    Bill

    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

    My 98 V70 came with a few Torx screwdrivers in the toolkit. Have you
    checked around the spare tire to see if the proper size is there?

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

    In an earlier contribution to this discussion,
    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?

  6. 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.)

    In an earlier contribution to this discussion,
    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...

    Bill,
    I take off the cap & rotor every year to clean the points of carbon
    deposits on my '95 850 an the rotor is held on by 3 mm. Allen head
    bolts, not torx.

    Bill,
    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.
