Hood latch spring failure

    My 1990 240 popped up an odd little failure yesterday. Two of them
    simultaneously, actually.

    It was reluctant to start and was stumbling on acceleration from a stop;
    this was following several days of rain and in the past this has
    indicated new spark plug wires being necessary. So I popped the hood
    and the wires looked fine. I noticed a strong gasoline smell though and
    started looking around. I found a fuel leak just in front of the left
    rear wheel, dripping off a sort of cage around what is probably the fuel
    pump (I haven't looked at my manuals yet to verify, and I'm not going to
    fix it myself anyway. It's also due for a new fuel filter and the
    in-tank pump makes a lot of noise too so there are several issues to
    attend to).

    Figuring that the fuel leak may have been causing the slight stumble, I
    closed the hood. It wouldn't stay down. Further investigation showed
    that the hood latch retention spring had broken off. Jeez. Now this
    seems like something I could fix myself- the question is, do I need a
    specific part from Volvo or can I find something suitable at the
    hardware store?

    The fuel pump and filter are both mounted in that bracket, that leak
    certainly needs to be fixed ASAP.

    I'm sure you could find a suitable spring somewhere to replace it, but I
    would just go to a salvage yard and get one from another 240, there are
    millions of them out there and I've never seen that spring break so
    there should be plenty of good ones.

    Yes, leaving a trail of gasoline is a bad idea on many fronts. I'm
    hoping my mechanic can take it in tomorrow.
    Looking at the latch, that spring looks surprisingly non-robust. It
    appears to have just rusted away.

    Thanks!

  4. in the 70's & 80's there were junk yards. i often knew who had what
    vehicles so" presto replaco" i could find what was needed by whom.
    mais, l'est plus ca change le plus ca reste meme. we no longer have
    yards we have ip adresses. i know a "few" dismemblers but all their
    stock is on line.

    you don't need the exact spring. @ first guess many other (read
    American) hoods opened the same way. on line there will be people who
    sell just spings. if you are smarter than the average bear, you will
    find one that works. i own an R which i race.... so Volvo, small
    package, Swede-air -- first class oh, & two points of attachment,
    2x$millions. right now my hood doesn't pop. instead of springs, i use
    my wallet or a book, or a.....

    the filter, pump, bracket arrangement was fairly comman @ that time.
    after 20yrs the connections become aged & fiddled/ refiddled w/. my
    lines are monel, "steam fitted" & inspected frequently. alot of vinyl
    ended up being used. 5 connections 20 cm -- Houston we may have a
    problem.

    Depends on where you are I guess. There's at least half a dozen well
    stocked U-pull yards within an hour or so of me, about half of which
    have a good selection of Volvos and cheap prices. Seems to be a thriving
    business, the places are almost always packed, especially when the
    weather is nice.

  6. Don't forget a new fuel filter as well and maybe the tank sock filter.

    They ought to be over full after the cash for clunkers debacle.
    My uncle is in the used car business (karnutz.com, voted the most
    irritating web site on the net) says the junkyards he uses were giving
    parts away to make room...

    Today the leak was fixed, apparently two things were involved. The
    first was that the fuel filter hadn't been changed in about 100,000
    miles. The second was corroded aluminum washers/gaskets where the fuel
    line attached to the fuel filter.

    It was also discovered that the in-tank fuel pump has no output (e.g.,
    it's not running). So that's on the list of things to do. A couple
    other things were noted included a control arm bushing needing
    replacement (which I knew already but had forgotten about) and an inner
    tie rod end starting to have some movement.

    Jeez, these 20 years old cars... I'm delighted to have it back and
    running well, now on to fixing the newly discovered issues.

    The pre-pump failure is very common, and will eventually lead to failure
    of the main pump. The rubber accordion hose to the pre-pump is almost
    certainly split as well.

    Ah. That would be bad. OK, the to-do list:

    Left control arm bushing (probably should just do all of them)
    Inner tie rod end(s)
    In-tank pump and associated bits
    Replace the plastic radiator with a metal one
    New plug and coil wires
    Replace the bracket by the coil, which is cracked
    Repair or replace the driver's seat.
    Replace the center console/rear seat ashtray assembly

    I think that's about all the known stuff until the next timing belt
    change which is 20,000 miles off.

    I'll trade you chores. I'm about to do motor mounts on my '83.

    fwiw, I got seats at a pick a part (ecology center?) for $40.00 each.
    They were cloth instead of plastic. Dirty but cleaned up nice. Beats the
    heck out of sitting on springs and foam.
    Can't hardly do much fixing for that kind of money.

    Cool! No, wait. Not. I'll keep mine, thanks. ;-)
    On mine the lumbar support adjustment failed resulting in a rather bowl
    shaped seat back; I understand this is basically a glorified string on a
    winder. And I think one of the wires in the mesh of the seat failed,
    too. The odd thing in that the seat back leans unevenly, farther back
    on the right side than the left. I wonder if there is a cracked frame
    member. One of these days I'll pull it out of the car and get the
    upholstery off to have a look at it.
    True. If I could find a good driver's seat for $40 I'd probably just
    swap that in. I vaguely recall "Road & Track" making up a hotrodded
    turbo 240 and putting Recaro seats in the thing; the idea was that a 240
    was basically invisible to police so it was a stealth hot rod.

    String on a winder. Yup, more or less. Repair kit available at dealer.
    Also, look in 700/900 FAQ, there is something in there about repairing
    a broken winder.
    Nope, probably not anything cracked. I once had an '86 240 wagon
    with that exact symptom. Along with the broken lumbar support. Damn
    near ruined my back before I fixed it. I removed the seat from the car.

    IF YOU HAVE AIRBAGS, DISCONNECT THE BATTERY AND LET
    THE CAR SIT 30 MINUTES. Otherwise, if you don't, and you hit the
    sensor under the seat, bang goes the airbag.

    Next, I figured out how to separate the seat back from seat bottom,
    basically
    unbolt some stuff, pull out rod connecting left and right, separate back and
    bottom,
    or something similar. Unclip and unroll upholstery on back to expose lumbar
    mechanism. Fix. Replace upholstery. The reason the the back was tilted
    was
    that the 2 separate gear sections, left and right, became 'unsynchronized'.
    You
    need to figure out how to assemble everything so that it all moves at the
    same
    pitch. It might have been something like get both gearsets to the same
    extreme
    end position, (all the way back?) and then assemble...??? It's been so long
    (I now do only 940's and 740's), so I don't remember if it might have been
    in
    the Haynes book, or I found something online. It must have been somewhat
    intuitive, or I would have screwed it up. All I know is that I got it
    right, and my
    back loved it.

    best of luck, /glenn

    My lumbar support went boing one day as I went over a speed bump. That
    was long after I was sitting on springs and foam though.
    My 'pick a part' seat has exactly the same issue.
    Boneyards are full. Go get one.

    I vaguely recall "Road & Track" making up a hotrodded
    After looking at prices for foam, covers, etc. I figured I could buy a
    Recaro, or Corbeau, or Sparco, for less than fixing the stock one.

    Motor mounts are pretty easy, last time I changed a set it took about 2
    hours including jacking up and lowering the car. You'll want a decent
    floor jack and a block of wood to put under the oil pan to lift the motor.

    Probably, I've seen several cracked seatback frames. Fortunately
    replacements are not too hard to find so far.

    I hadn't thought of that until today, but as I am 6'4" and 220 lbs it
    wouldn't be a surprise.

    Open the seatback and have a look, if you can't find a replacement, you
    can weld the frame, it's just steel. Let me know if you need tips for
    getting the seat apart or back together, I've done quite a few seat
    rebuilds.

  19. The frame breaks or bends on that side as yopu tend to lean with pressure on
    the seat to reach kids or objects on the back seat .In Taxi cabs its common
    ..

    I've never pulled one apart and haven't looked at it closely. Are there
    photos somewhere to see the process?
