Will have an auto tensioner. will always be tight enough. if not, would squeel when you turn your ac on. if it does then you need to replace your tensioner, maybe your belt too if its damaged

Tighten Serpentine Belt

Technically, you don\'t. The tensioner pulley keeps the belt tight. If you took the belt off and put it back on, and now it is not tight, it may be on one of the pulleys wrong.

How do you replace a serpentine belt for 1996 jeep cherokee sport?

You need to loosen up the power steering pump and un-adjust the jack bolt that runs under it. Then just follow the diagram on the sticker on the radiator support. If you can't find the sticker, I'll give you the routing if you ask. to tighten the belt just tighten the jack bolt and lock down the bolts you loosened on the pump. Tight is when you have about one inch deflection in the longest run of the belt,
Loose is better than too tight as you can re-tighten it if necessary. Too tight will damage pulley bearings.

Replace alternator belt

  • Locate the two belts on the left side (passenger side) of your Mitsubishi Lancer. The outer belt is a serpentine belt, operating four pulleys and the inner belt is your alternator belt.

  • 2

    Follow the serpentine (outer) belt to the three pulleys lined up vertically near the front of the engine compartment. Locate the middle pulley, which is the tension pulley for the belt.

  • 3

    Loosen the bolt on the middle pulley with a socket wrench by turning counter-clockwise. Do not remove the bolt, just turn it a couple of times. Loosen the tensioner bolt on the side of the of the pulley, facing the front of the vehicle.

  • 4

    Remove the serpentine belt and then loosen the bolt on the alternator. With the alternator loose, move it forward so that the alternator belt loosens up and then remove belt from the pulleys.

  • 5

    Install the new alternator belt by placing it over both inside pulleys. Tighten the tension on the alternator belt by moving the alternator back and keeping tension on it by holding it back with a long screwdriver. While the alternator belt is tight, use a socket wrench to tighten up the bolt on the alternator.

  • 6

    Place the serpentine belt back on the pulleys and then use a socket wrench on the bolt on the front of the tension pulley. Once the serpentine belt is tight, tighten up the bolt in the middle of the tension pulley.

  • 7

    Start the Mitsubishi Lancer's engine to test the alternator belt and make sure it is working properly. Once you have verified it is working, turn the engine off.

    Serpentine belt tensioner will not tighten

    If the tensioner will not keep the belt tight then the tensioner is bad and will need to be replaced. The spring on the inside will loose it's tension over time.

    loosen the the two bolts (show on the figure above) first
    loosen also the bolt used for adjusting tension.
    remove the old worn-out belt.
    place the new belt (you may need to loosen further the tension adjusting bolt)
    when belt is properly place, tighten it enough the tension adjusting bolt,
    (not too tight, but not too loose) press the belt to ensure its not too loose!
    When belt tightness is enough, tighten the the other lower one of the two bolt then the lastly tighten the pivot bolt.

    there is a tensioner on that. it will take i think a 14mm or a 15 mm and the 12mm for the bolt that tightens the belt after its kinda tight not real tight then use the 14 or 15 mm to snug down the tensioner nut .
