Question about 1994 Dodge Caravan
I looked it up and found that the 3.8L engine is found on a Dodge 'Grand' Caravan.
The 'Dynamic Tensioner' has to have the belt removed first, then it unbolts with a socket wrench or regular wrenches.
3.3L and 3.8L Engines ACCESSORY DRIVE BELT Fig. 14: Accessory drive belt adjustment — 3.3L and 3.8L engines
All of the belt driven accessories on the 3.3L and 3.8L engines are driven by a single serpentine belt. The belt tension is maintained by am automatic tensioner.

Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight. WARNING
A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.
