In a 94 chevy cavalier the tensioner is pulled towards the front of the engine compartment with a 15 mm socket, when the alternator is replaced the tensioner is pushed back towards the rear of the engine compartment, in this tightening procedure does the tensioner get pushed back as far as it can go or is there some point along its potential arc that it is supposed to stop.Is the tensioner suppose to lock or bar or it it pushed just far enough back to achieve the good tension, would a belt that is too loose or too tight prevent the car from turning over.

The tensioner usually has an internal stop that will be felt as you loosen or push back against spring pressure. There is no lockout; you have to hold the tensioner back out of the way, against spring pressure with your wrench
As for retensioning the belt the tensionners spring is suppose to do that all on its own with its spring as you release it.
If the belt is to loose or the tensioner doesn’t spring back on its own as you release it then it’s time to replace the tensioner.
If the tensioner not seized; its spring hasn’t broken or become weak; if the belt is of the proper length; there is no such a thing as a to loose or too tight belt when it comes to this system
A loose belt will allow pulleys to slip causing different issues such as the alternator not charging the battery or the power steering to become jumpy; usually accompanied with a squealing belt.
To tight will usually cause a belt to fail or this excessive tension will damage bearings on/in anyone of the pulleys the belt is turning.
So I guess a loose or an over tight belt could stop an engine from turning indirectly? Because of a dead battery or a seized pulley and the started motor can’t crank the engine.
