To adjust the belt tensioner on a 1992 Mercedes-Benz 190E 2.3, first, locate the tensioner pulley and the adjustment bolt. Using a suitable wrench, loosen the adjustment bolt slightly, then use a socket or ratchet to rotate the tensioner arm, relieving tension on the serpentine belt. Once the desired tension is reached, tighten the adjustment bolt securely. Finally, check the belt's tension by pressing down on it; it should have slight give but not be overly loose.
