Why does the serpentine belt keep slipping off the bottom pulley after replacing the belt and tensioner on a 1995 Ford Thunderbird V8 4 6L?

Chances are the belt and tensioner is not the problem. Your water pump is. Check the bottom of the water pump and see if there is some anti-freeze comming from the weep hole. If there is then that is the problem. Anti-freeze will cause a serpentine belt to come off because of its lubricating properties If there are not leaking fluids dripping on the belt that would cause it to come off then, it sounds like a belt alignment problem. You should check your mechanics guide to determine how to adjust the alignment.

On vehicles with a single serpentine belt, tension is usually self-adjusted automatically via a spring loaded tensioner. No additional adjustment is necessary. If the belt is slipping or loose, then it needs replacing. Also check the tensioner bearings and replace the tensioner if necessary.

tensioner wobble , check all pulleys for straightness and replace as need

If you're certain that the sound is from the serpentine belt you should check the belt tensioner. A weak tensioner spring will result in slipping and a noisy belt.

The serpentine belt on a 2003 Dodge Dakota is replaced by loosening the belt tensioner and slipping the belt off. It can then be removed from the engine accessories and a new belt installed.

Engine used a serpentine belt, with a spring-loaded tensioner. You cannot tighten the belt. If the belt is slipping, either one of the driven components is going bad and dragging the belt, or the tensioner is bad.
