I have looked through all Sunbird posts

[Loonerone]

and have not seen any relating to removing and replacing the Drive Belt Tensioner.
'93 LE with 2.0 L4.
Should I look as well in the threads of Sunfire??

There is a very evident squeal emmanating from the engine front and the squeal was somewhat lessened by having the Alternator rebuilt.
The squeal may well be additionally from the Timing Belt Tensioner since it has not been replaced for over 80,000 miles.
>>I'm curious as to the Drive (Serpentine) Belt Tensioner Bolt size (?mm and length of Bolt because of limited access and no size offered in a Haynes manual) as well as Person or Persons that have done such fix that can provide requested/adequate/relevant information.<<

Thank you for your time and assistance/information.

The end result of the elimination of the main squeals were/are from:
New Timing Belt and Water Pump.
New Belt Tensioner installed without additional charge (because the Mechanic stated such and confirmed on the billing).
There is still a remaining squeal which is the Alternator and it was again worked on at the shop that did the rebuild. There were bearing replacements and the Pulley Nut was white from some odd overheating.
The alternator squeal is just a squeal that is seemingly impossible to eliminate.

Thank you Dr. Sievers and all others.

I don't get the connection the " timing belt" has with an alternator or tensioner squeal?

EVERYTHING mechanical breaks down.​

Yes, while there is no discernable connection between these components, these parts needed some attention.
The squeals were indeterminate apart from the Alternator yet were loud especially in wet weather.
The tensioner of the timing belt has the same characteristics of the tensioner of the exterior component(s) drive belt and thus will wear out and squeal, like ANY bearing equipped device/construct.
ALL squeals apart from the peculiar one of the *rebuilt* Alternator have disappeared. *bearings replaced twice*
