Alfa156 AC ventilation repair

With the dashboard removed, it is a good time to fix several typical Alfa 156 issues, mainly relating to the AC ventilation control.

AC ventilation – internal circulation malfunction

My 156’s air conditioning internal circulation function has not been working for long. The main reason is a broken gear in the flap control box

Broken gear in the control box

There are 2 means to fix it:

  • Replace the gear. I was lucky enough to find the gear from Taiwan. An alfisti there produced a small batch of the gear.
  • Replace the entire box

The real challenge, nevertheless, is to get the control box out. I’d say it is almost impossible to do it without removing the dashboard, at least it is the case in the RHD cars. Many just use a wire to fix the flap at the close position. It is a simple fix and indeed we do have the internal circulation on most of the time. Albeit, I still want to have it work properly. So leveraging the opportunity, I had it fixed.

To ensure success, attention must be paid to the existing pivot position. It must be in the same position when it is reassembled.

While other ventilation control of my 156 seemed to work properly, I decided to have a look at their condition too. And I’s glad that I have done it.

Gears of the other 2 control box are broken too. Even though they were working without problems, I replaced the gear right away. Having said that I’d not suggest you doing so unless you already have the new gear ready. No problem, don’t fix it, the golden rule of thumb.

At last, the working internal circulation flap

    That’s a great write up, one of the best 156 blog out there.

    I am wondering if there’s a Taiwanese forum dedicated to 156 owners? I have recently acquired one and looks like Taiwan has some very active owners for this car.

    Thank you in advance.

        Thank you so much!

        Very excited as mine will be landing in west coast US very shortly as they are just turning 25 yrs old, anything would help getting any potential issues sorted out in the future.

  2. We will go over completely different variations of bench presses further below, however because the flat bench press is the primary chest press exercise,
    it deserves the most element on form. Plus, plenty
    of these similar cues apply to all the opposite chest presses, as you will see, and if they do not we will make note of
    it. All that stated, grasp the flat bench press first and
    your life might be lots simpler if you start studying and implementing the incline and decline bench press into your
    exercise program. If you discover the incline bench press uncomfortable, a fantastic
    alternative is the incline dumbbell press. It works the same muscle groups, however some people discover it more comfortable and that they will prepare via a longer range of motion than with
    a barbell. Most individuals carry with a slightly longer range of movement in the incline bench press in comparability with
    the flat bench press. You can merely decrease the bar further earlier than it stops in opposition to
    your physique.
    If you want to crush PRs, add slabs of muscle, or shed weight, KIZEN has
    the proper program for you. Now that we’ve covered the primary differences between these
    two exercises, let’s go over the professionals and cons of every, which
    is ready to additional allow you to determine which one is finest on your goals.
    What most trainees do mistaken is to try to use their abdominals and hip flexors in a flexing and curling movement.

    In Any Other Case, you might have little or no control over the shoulder advanced and you can not set the scapula.

    Yes, the dumbbell bench press is a great different to the barbell bench press and offers added benefits of stability
    and increased vary of motion. The triceps brachii, situated at the again of the higher arm,
    act as synergists through the flat chest press.
    They assist the chest muscles in extending the elbows and
    finishing the pressing movement.
    Whereas the Overhead Barbell Press is a great higher body
    pushing exercise too, the Bench Press permits for larger strength just because it’s easier to progress with.
    Hold your shoulders (rear delts) on the bench all through the lift.
    A good cue is to consider pushing your self away from the bar rather than pressing the bar away from your chest.

    I liken these three bench press variations to squatting via totally different
    ranges of movement. When we expose ourselves to different ranges
    of movement we’re going to coach the tissues utilized in these ranges to be
    extra resilient.
    Quite than doing numerous more isolated workout routines for numerous reps, you’ll be able to bench press heavy loads (relative to your
    strength) with much less volume to the same and even larger effect.
    Each barbell bench press and dumbbell bench press ought to have their place
    in the common weightlifters routine. Another beauty of lifting heavy,
    which you can do with bench press better than some other
    upper physique train, is that it boosts the pure manufacturing
    of testosterone. The more testosterone in your body, the more muscle you’ll construct and the stronger you will get.

    This can be an essential distinction to contemplate for beginners and intermediate lifters.
    When serious about training the pecs, I break them into three different divisions and these include
    the sternal pec fibers, clavicular pec fibers, and costal
    pec fibers. Each of these bench press variations will practice
    these divisions of pec fibers to completely different degrees.
    If you prepare each the flat and the incline bench press equally exhausting
    and persistently, you will with time develop the strength ratio that
    is “correct” for you.
    After the athlete is seated on the bench, they should firmly grasp
    the dumbbells and carry them onto their knees one by
    one. As the athlete lays down, they should “kick” the dumbbells up above their chest.

    If you’ve shoulder injuries, it’s essential to
    seek the advice of with a healthcare professional or a qualified fitness trainer for workout routines which
    might be appropriate for your particular condition. Taking
    the time to heat up correctly enhances efficiency
    and reduces the danger of pressure or harm.
    The key to gaining these advantages is to remain constant,
    maintain yourself engaged by way of its variations, and follow a wholesome lifestyle.
    So as you’ll have the ability to see there isn’t a exact science to calculating your barbell bench press based of your dumbbell press.
    But you’ll find a way to determine it out simply by beginning light on your bench press and growing from there.

    Experiment with completely different inclinations, grip widths,
    and bar paths to search out what feels greatest in your physique.
    This is as a outcome of when the bench is at an incline, your upper pec muscle fibers shall be directly beneath the line of force.
    In the flat bench press, the line of drive passes via the middle of your chest muscle tissue,
    and this is why the flat bench press is such an excellent general chest builder.

    Newbies can benefit from bench presses without weight on the bar to warm up, get a feel for the bar, and be taught proper type.
    If you are extra advanced and bench press with heavy weight,
    use a spotter. Also, a pair of weightlifting gloves can provide
    you a better grip. Relying on your goals, there are different variations of bench presses that work slightly completely different muscle
    tissue, too.
    Whereas the Smith machine supplies stability,
    it could not engage stabilizer muscle tissue as successfully as free weights.
    Dumbbell presses require extra stability and coordination, potentially main to higher
    muscle improvement and practical power. By learning the best form and utilizing it in your exercises, you’ll unlock
    your higher body’s full potential. Remember to warm up, progress
    steadily, and prioritize safety for the best
    results. Keep your head flat on the bench and feet flat on the floor for stability,
    however do not push your head into the bench to assist the
    lift—firm up the neck muscles as an alternative.
    Contrary to some weightlifting security recommendation, you can “lock out” your elbows when doing a bench press.
    The key to creating this motion protected is to not
    lock your elbows all of a sudden or explosively.

    Correct breathing patterns and lifting tempo are essential for maximizing the efficacy of the Flat Dumbbell Press.

    Inhale as you lower the dumbbells, keeping the movement regular and unhurried.
    This not solely helps in stabilizing the core but in addition ensures a rhythm that can improve focus and power era throughout the raise.

    Following this sort of diversified routine is necessary to
    make sure you’re working your whole physique. This sort of weekly routine also
    lets you take rest days to permit totally different muscular tissues to recuperate.
    If you want variety, you’ll have the ability to pick
    2 or extra variations per workout. Attempt to give your self
    1 or 2 rest days, allowing muscle tissue to recuperate earlier than switching
    between the other variations. Steven is a licensed

    Dumbbell bench press challenges are numerous targets or exams that an athlete
    can full. They are a means for athletes to push themselves to accomplish more in the weight room.
    If you may be able to dominate the dumbbell bench press,
    you need to comply with these six steps. Your elbows should be immediately below your wrists
    as you prepare to decrease the dumbbells. Preserving your elbows and wrists
    in alignment will maintain your shoulders within the appropriate place.
    To set your back, flex your shoulder blades and
    squeeze them together.
    The greater the angle, the extra the exercise will have interaction the shoulders.
    After those 2 weeks, you can start to use progressive overload by lifting
    heavier dumbbells and decreasing reps. Let’s clarify- it’s okay if you are a thin beginner to lift mild and in excessive rep ranges of 15+
    per set if you first begin coaching.
    Nonetheless, if you would like to achieve sheer power,
    compete in a powerlifting meet, or have more power & explosiveness on the sphere, a flat bench press is the way in which to go.
    Whether you’re an athlete or not, it’s a good
    idea to include each bench press variations into your routine.
    They may target the same muscle groups, however they every supply distinctive benefits.

    Throughout this step, you would possibly be making ready your body to execute the lift.
    This step is the foundation of performing the dumbbell bench press.
    The triceps brachii is situated on the bottom of your upper arm.
    When you straighten your arms, the dumbbell bench press works your triceps at the end
    of the press. Variations of the dumbbell bench press include the incline,
    decline, ground, wrist rotation, neutral grip, alternating,
    and single-arm.
    As with any exercise, changing the incline is a helpful method
    to swap up your training every few weeks and hit your muscular tissues in new difficult ways.
    Heavy lifting is right for constructing muscle, gaining strength, and enhancing your dumbbell bench press.

    You can even do dumbbell squeeze presses, alternating dumbbell bench presses, and single-arm dumbbell bench
    presses utilizing a stability ball. To get essentially the most from this
    (or any other) train, you must do it correctly. Doing the dumbbell bench press with incorrect kind
    will make it less efficient and could increase your danger of damage.
    If you’re a true newbie, then you really simply want to stay to a minimum of one bench press variation, and we might recommend that to be the flat barbell
    (or dumbbell) bench press.
    Convey the weights to your knees in order that the dumbbell ends relaxation on the knees and sit again onto
    the bench so that the bells are planted
    in your knees and you’ve got a “hammer” grip. Include these exercises 1-3 instances weekly, relying on your exercise split.
    Guarantee adequate relaxation between classes for muscle restoration and progress.
    Outcomes depend on consistency, correct kind, and vitamin, rather than the
    sort of press.
    With that in mind, the flat bench press will be your most “generalist” of
    those three bench press variations. The incline bench press is usually the second most
    popular choice to carry out and the decline press is essentially the most specific and often least used.

    The dumbbell bench press is a compound exercise that
    targets the pectorals, triceps, deltoids, and rotator cuffs..

    Frequent mistakes embrace using a really broad arm path and pressing the dumbbells straight up and down, which may result in shoulder pressure.
    It’s necessary to maintain correct kind by maintaining
    the elbows slightly tucked and following a natural
    arc during the press. The quantity of weight that you must
    bench press is determined by a quantity
    of components, including your health degree, size and build, lifting experience, and objectives.
    For best outcomes, be sure to carry out bench presses on nonconsecutive days so
    that your muscles have an opportunity to completely recover.
    Yes, many think about the dumbbell bench press an essential weight lifting exercise.

    The incline press also hits the anterior head of the
    deltoid muscle of the shoulders or the front a part
    of your shoulder. The guillotine bench press works the same muscles as any bench press
    (chest, shoulders, triceps). However, because of the distinctive path of the bar and the way the elbows are flared, you’ll be minimizing the anterior deltoids and maximizing
    your higher chest (clavicular head) significantly.

    In truth, some EMG research actually show it’s higher than another bench
    press for complete pec main activation. The solely problem is,
    it’s extra dangerous considering you’re lowering the bar
    to your neck and could be more durable on the shoulders because you elbows are flared.

    This hybridization ensures optimum efficiency and mitigates
    injury risk, making a well-rounded athlete. If you end up straining towards the tip of a set,
    ask a friend to spot you as you raise. This will permit you to
    finish your set without altering the motion. If you
    discover yourself over-arching your again from the get-go,
    choose a lighter set of dumbbells. When you are fatigued towards the tip of a set or if you’re trying to lift extra weight than you want to, you might end up straining and over-arching your again to
    attempt to drive the dumbbells upward. When you velocity via
    a motion like this, you discover yourself losing the target focus for
    the train, allowing different muscle groups and momentum to help
    you full the transfer. This might not seem like a big deal,
    but it finally ends up lowering the effectiveness of your exercise, making it
    more durable to see the improvements you need to see.

    Furthermore, every arm is unbiased of each other, which forces extra stability, thus making things tougher.
    Apart From bodily advantages, the bench press is fairly simple to be taught and its efficient.
    Basically, at the top of the carry, the bar is directly over your shoulders and at
    the backside when the bar touches your chest your forearms are vertical.

    Overall, by squeezing your shoulder blades together, your chest
    will lift up a bit in path of the ceiling and
    you’ll naturally have a mild arch in your thoracic spine.

    This will guarantee security of your shoulder joint and maximum energy.

    A 30° inclination is sufficient for considerably higher
    upper pec activation compared to the middle and decrease pec.

    They work several different muscles in your higher physique,
    including the chest, shoulders, and arms. Cortisol can be produced when performing the dumbbell bench press.

    Nevertheless, cortisol helps the physique create
    vitality by consuming tissue. Preserving your cortisol levels
    low by resting between sets of snatch-grip
    deadlifts is important. It makes use of the same form as a barbell bench press, but lifters
    have a higher range of movement, so it’s simpler
    to beat plateaus. Deciding On the appropriate weight for
    a dumbbell bench press is essential for performing this exercise.
