It would be difficult. I would not attempt it unless there were parts from a later model that would interchange with it.A salvage yard might be able to answer interchangability issues.
Yes, it is possible that a cracked serpentine belt will cause poor fuel economy. Many people will have significantly improved gas mileage after changing the belt.
No.
If you are asking about changing a person's sexual orientation, it's not possible nor necessary. Just be a good friend.
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
No, not at all possible. But constant speed with changing velocity is possible.
In same models this is possible.
POSSIBLE CRANKSHAFT POSITION SENSOR.
Changing the depth of field.
You had to have disrupted something else while you were changing the serpentine belt. I've driven a short distance without the belt at all so just changing it shouldn't have any side effect like not starting. Check all your electrical connections and be certain you didn't dissconnect anything while you changed the belt. It's possible that your battery is dead if you drove a distance without the belt in place. The belt is needed for the alternator to charge the battery but this would be the only way I can think of that changing the belt would cause your car not to start.
A serpentine belt has an idler pulley on is to keep it tight at all times. If your serpentine belt is loose, then something is worn out. Its possible the idler pulley is stuck in its bracket so it cannot move or the spring on it is worn out.
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)
yes
