This is how tight the bolt is done up, the manufacturer will specify this is newton meter or foot pound. You will then need a Tourque wrench to measure the force as you tighten the bolt.
What tension bolt? There are many bolts under tension.
Loosen bolt in tension pulley, then loosen tension bolt. Replace belt. Tighten tension bolt. Last, tighten bolt through pulley.
It is torsion and tension while tightening, and pure tension when tightened
Looking into the engine compartment from the passenger side you you will see two large bolts and a smaller bolt on the alternator. The large upper bolt is the pivot bolt, the lower bolt is the locking bolt. The third bolt is used to adjust belt tension. 1. Loosen the alternator locking bolt. You may need a breaker bar to free the bolt. 2. Loosen the pivot bolt. 3. Turn the tension bolt counter clockwise to loosen tension, clockwise to increase tension. 4. Tighten the pivot bolt and locking bolt.
Pretensioning is the tension on the bolt (when fastening) without any load applied to the bolt
Loosen lock nut, turn tension bolt.
The tension bolt should not be removed. The four bolts holding the alternator in place need to be removed, the loosening tension bolt will give enough slack to get the belt off.
First you need a breaker bar and 19mm socket to fit the "tension bolt". Turn tension bolt clockwise to release tension in order to remove the serpentine belt.
The tension pulley should have a bolt that holds it on, allowing you to replace the unit.
It probably has a tension release pully, not a bolt. The pully has no function except tension. Your repair manual probably has instructions on changing the belt and a photo of the small pulley. Mary
Yes, it is used to adjust the tension on the A/C compressor. Looking into the engine compartment from the passenger side it is to the left of the alternator. To adjust tension you need to loosen the bolt which holds the pulley and then adjust the bolt which is directly above the pulley. Once you have proper tension tighten the pulley bolt.
