To re-install a belt tensioner for a 1987 Ford Taurus, tighten the bolt when the tensioner pulley is holding the serpentine belt tight. The belt tensioner sits in a slot and can be adjusted to hold the belt tight.
The tensioner pully is just to the left of the alternator. It is an arm with a round pully on the end of it. It has a square 3/8 ratchet attatchment. It is about 7 inches long.
You have to install a new belt tensioner.

Sorry, we can't do pictures.
you do not need a tool to tension pully belt if belt is loose, belt needs replacing tensioner works automatically
get a 1/2 drive rachet and a socket that fits the tentioner pully hand pull the pully to slack the belt pull the belt off and let the pully back in placethen you can loosen the nut ans tap the pully off if needed
It uses a spring loaded belt tensioner. The tensioner is autmatically set. IF there is not enough tension, then replace the tensioner. The belt may be stretched and need replacment however.
Something is out of line. Check alternator, a/c pump, idler and tensioner. I've had 3 Taurus and never a single broken belt.
