There is an adjustment on the Power Steering pump to tighten the belt. About 1/2 inch deflection is correct tension. Too loose or too tight will put undo stress on the bearings & cause them to wear early. I usually soak the bolts with penetrating oil before trying to adjust since they will probably be a bit stuck. It helps avoid breakage.
Loosen up the power steering pump and pull on pump till belt is tight.
Should have an automatic belt tensioner - if tension not correct replace tensioner
A serpentine belt has an idler pulley on is to keep it tight at all times. If your serpentine belt is loose, then something is worn out. Its possible the idler pulley is stuck in its bracket so it cannot move or the spring on it is worn out.
Loosen bolt in tension pulley, then loosen tension bolt. Replace belt. Tighten tension bolt. Last, tighten bolt through pulley.
it is adjusted throught the power steering pump loosen the adjuster bolts remove belt and reverse
Your belt is probably stretched or the tensioner is weak. Try a new belt, or replacing the tensioner. If it is still loose get a 1/2 inch smaller belt.
You can obtain a serpentine belt diagram have most Chrysler/Jeep dealerships. The serpentine belt diagram can also be found at most auto-parts stores.
Should have an automatic belt tensioner -perhaps it is defective I don't think there is a belt tensioner. Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.
I need a routing diagram for the serpentine belt on a 1998 Jeep Wranger, 4 cylinder, with air conditioning
its self adjusting
not from the factory
A/C Condenser is on the serpentine route.
