Need to tighten the belt and nothing looks movable. Anyone have a diagram?

You cannot tighten it, the belt tensioner needs to be replaced.

Belt pulley and belt tensioner. Belt pulley is fxhed and tensioner is movable. You need to have belt tensioner relased of the pressure using belt tool (long handle and 15'' wrench) .. Then you can folow belt routing diagram located on fan shroud or underneath front hood!

You should be able to tighten it by adjusting tensioner pulley

There may be a diagram imprinted on fan shroud. There is a belt tensioner that tightens the belt. Also when installing belt be sure you have grooved part of belt riding on grooved pulleys. And flat side of belt riding on flat sided pulleys.

Really don't need a diagram. Loosen the slide bolts on the power steering pump. loosen or tighten the pump by turning the jack screw (long transverse bolt) under the pump. Once the belt is tightened up, lock down the slide bolts and you are finished.

Below are diagrams for both the M44 and the M50 engines. On the M44, you may need to hold the tensioner in the retracted position with a drill bit or hex tool through the hole in the front of the tensioner. The belt tensioner is automatic so no tightening is necessary. Best of luck!

I thought the same thing on my 1998 plymouth breeze but it was because I didn't route the belt correctly. Maybe this will help:

go to 2carpros.com, look on left side of column, click on belt routing diagrams, click on year, model, type, and it will have the diagram that you need!

I can't send you a diagram,but it's not too hard to explain. Loosen off the alternator first. Two bolts, one you can see that goes through a bracket on the engine and another that is directly under that bolt on the bottom of the alternator that goes into the engine. Fit your new belt over the fan first, one blade at a time and on the pulley. Run the belt down to the bottom crankchaft pulley and then across to the alternator. Before you tighten the belt make sure that all 3 pulleys are in a straight line when you look from the side. If not move them so they are. Take a long screwdriver and put it in the hole on top of the alternator bracket and pry the alternator over so the belt is snug and a little bit more. Tighten the top bolt first,but be careful because it can strip the threads. Then tighten the bottom bolt.You will probably have to retighten it after a few days because the belt will stretch. If the belt squeals when you start or rev the engine then it needs to be a little tighter. If you strip the top bolt, just take it out and find a smaller one with a nut and washers and use it with the washers on the front to keep the new bolt from pulling through the bracket. Hope this helps.
