How do you adjust the belt tensioners on a 2004 endeavor?

To adjust the belt tensioner on a 2004 Endeavor, first, locate the tensioner pulley, which is typically accessible from the front of the engine. Use a wrench or a socket to turn the tensioner counterclockwise to relieve tension on the serpentine belt. Once the belt is loose, inspect the tensioner for wear or damage; if it needs replacement, remove it and install a new one. After replacing or adjusting, ensure the belt is properly aligned and tensioned before starting the engine.
