1994 suburban belt tensioner

I am trying to put the alternator back on my suburban. I am trying to figure out which bolts to loosen to relieve tension on the belt so I can put the alternator back on and then get the belt back to where it was.

The tensioner pulley is right on top of the motor and all you do is use a socket to release the pressure long enough to put the belt back on

Tensioner location on 97 chrysler sebring 2.5L 6 cyl


The tensioner pulley looks like an idler pulley, only with an adjusting bolt protruding out about 2 inches from just behind the pulley. Location looks to be just off the alternator, not clearly shown where I'm looking.
To loosen belt, you loosen the tensioner pulley nut, and then turn the adjusting bolt in to relieve tension. When putting the belt back on, adjust tension with adjustment bolt, then tighten the pulley nut. This is for Sebring Coupe, Convertible is different. Good luck.

What do I loosen to get 1st belt off so I can change ac belt?


Assuming you're talking about the 22re ... there are tensioners on both the power steering (first) and the a/c belts. Loosen the bolt on the pulley and then the bolt on the side of the tensioner tightens and loosens the belt. You might want to check the inner ... alternator / water pump belt while you're there. No tensioner for this one, you need to loosen the bolt that the alternator pivots on, loosen the bolt on top of the alternator that holds it in place on that bracket and then pry alternator and tighten bolts to hold the tension.

How to releived the tension on the belts when removing the the alternator on A 1995 jeep wrangler


Serpentine Belt:

If there is a tensioner with a spring, then put a 1/2" breaker bar on it and rotate the tensioner to relieve tension.

Conventional V-Belt:

Loosen the nut and bolts for the alternator to swing it in a way that relieves tension on the belt.

May have to relieve tension on other belts in similar way to change the belt in question.

  2. Raise and support the front of the vehicle, then remove the passenger side tire and wheel assembly for access to the rear of the alternator through the wheel well.
  3. Working through the wheel well, unfasten the alternator brace-to-block bolt, then remove the brace-to-intake nut and the brace-to-engine stud nut.
  4. Unplug the alternator wiring connector, then remove the battery terminal nut and wire.
  5. Carefully release the serpentine belt tension and remove the belt from the alternator pulley. Do not allow the tensioner to snap back into position once the belt is off the pulley.
  6. Loosen the alternator retaining bolts, then support the alternator and remove the fasteners. Remove the alternator from the vehicle.

To install:
  1. Position the alternator in the vehicle and loosely install the retaining bolts.
  2. On 1994-98 models, tighten the top alternator bolt to 22 ft. lbs. (30 Nm) and the bottom bolt to 32 ft. lbs. (43 Nm).
  3. On 1999-99 models, tighten the rear bolt to 37 ft. lbs. (50 Nm) and the front bolt to 18 ft. lbs. (25 Nm).
  4. On 1994-98 models, install the alternator brace, then tighten the retaining nut(s) and bolts to 22 ft. lbs. (30 Nm).
  5. On 1999-99 models, install the alternator brace, tighten the brace-to-alternator and brace-to-intake retainers to 18 ft. lbs. (25 Nm). Tighten the brace-to-engine stud nut to 37 ft. lbs. (50 Nm).
  6. Install the battery terminal wire and tighten the retaining nut, then engage the alternator wiring connector.
  7. Hold the serpentine drive belt tensioner, back off the belt while slipping the belt over the alternator pulley. Gradually lower the tensioner into contact with the belt, then check for proper alignment and tension.
  8. Connect the negative battery cable.

    How do I release belt tension to replace alternator?


    Hi,according to what year you have.Look for either an adjusting bolt and through bolt at the alternator.Loosen both and push the alternator back.If it has an extra pulley look for a belt adjusting bolt close to this pulley.You have to loosen the bolt that goes through the front of this pulley.(the bolt that holds the pulley to engine).Then turn the adjuster to loosen belt.Some of the later models have automatic belt tensioners.You have to put a wrench on the tensioner pulley bolt and relieve the spring pressure.I hope this helps!!!Please rate this answer.Thanks and Good Luck!!!
