I don't know what car you are working on but usually there is a bolt that the pulley arm pivots on and another that will tighten and hold it in place. Look for that second bolt.
Power steering/Drive belt Adjustment To adjust P/S belt tension, loosen tension pulley bolts and turn tension pulley using hexagon wrench. Adjust belt tension to specification described in CHECK. Then tighten tension pulley bolts to specified torque. Tightening torque P/S belt tension pulley bolt (a): 25 Nm (2.5 kgf-m, 18.5 ft. lbs.)
You don't. The tension on the belt is held tight by a spring loaded tensioner idler.
The 1989 Toyota Corolla serpentine belt can be tightened or loosen with the tensioner pulley. Pry to the left on the tensioner pulley until the belt is tight. Tighten the tensioner pulley.
Yes, if the belt tension is not tight enough it won't spin the radiator fan due to slippage. Replace the tensioner pulley.
You release the spring tension on the tensioner, a pulley in the belt system who's only purpose is to keep the belt tight. Normally you can use a ratchet to move the pulley away from the belt, but some are adjustable and require loosening a bolt.
loosen the tension pulley bolt which is in the middle of the pulley, use a wrench, little work space is provided, just a little bit, then lossen the bolt that is behind the pulley, tho relive tension in the belt. take off the belt, and put on new one and tighten the bolt behind the pulley till belt is tight, then retighten the pulley bolt.
On the tension pulley above the AC unit there is a tension bolt behind the pulley. Loosen the front nut on the front of the pulley then loosen the long bolt to drop the pulley until the belt fits. Tighten the long back bolt until the belt is tight ( see manf. recommendations on torque ) then tighten the bolt on the front of the pulley.
There should be a tension pulley that keeps the belt tight. I have used a ratchet socket to release the tension. The belt can then be slipped off the pulley. Be sure to note the way the belt is wrapped around the various pulleys before doing this. It can be confusing to figure this out afterwards.
if belt needs tightening, u need a new belt serpentine belts use a tension pulley that automatically keeps belt tight until belt is worn out or stretched.
Check belt tension. Make sure all nuts and bolts are tight and that you did not pull the alternator tighter while mounting it.
The adjusting pulley for the power steering is found on the side of the engine under the power steering pump. Loosen the bolt that keeps it tight and the belt will have some slack to slide off the pulley.
