LMM Fan Belt

Working on the truck last night and noticed my fan belt is so loose you can take it off by hand without any effort. What is the best way to tighten the belt on this truck? I know the tensioner but where is it located and how do I adjust the tension?

Give it some time, someone will know. I'd say just take the dang thing to a dealership and have them fix it. It's gota be under warranty still.

Passenger side near the Alternator, but it Seems like you’re leaving something out here. Did you remove the belt, work on a component on the front of the engine, or alter something? There is no adjustment of tension on the Drive Belt, the Drive Belt Tensioner handles that. Is the belt routed incorrectly causing this slack? Drive Belt Tensioners do wear out, just not normally on a truck as new as yours.

truck is two weeks old. have not touched the belt or any of the components on it. was installing air filter last night and noticed how loose it is. I can literally take it off the alternator with my hand, you can move at least 3 inches of slack in the straight area of the belt. There is no adjustment on the tensioner?

A. Wrong belt installed. (unlikely)
B. Most likely, the belt routing is incorrect. Check the diagram up front for the proper routing of the belt. The tensioner has plenty of adjustment on it. It fact, with a normal handle length of a ½” drive wrench, you still need a pipe extension to pull that baby back all the way, there is that much pressure against the spring. It is very easy to miss one spot in the routing and still have the belt stay on with the available travel on the tensioner. I would recommend another set of hands to assist.
