1. Someone, unknowingly removed and replaced the belt incorrectly, by MISROUTING the belt on the pulleys.
2. Someone, unknowingly replaced the belt with one of the wrong size.
3. One of the belt driven components [water pump, alternator, smog air pump, Power Steering pump, air conditioning compressor, etc.] has been replaced with a new unit which has a different sized pulley than the one replaced.
4. The tensioning SPRING in the auto tensioning arm has become weak, and if so the arm assembly must be replaced.
As 1 implies, there is no provision for adjustment, as the tensioner arm assembly is supposed to automatically maintain the proper tension. j3h.
you do not adjust tension on a serpentine belt the tension is automatcally adjusted if the belt is loose, replace the belt SOME TIMES THE TENSIONER CAN BE WEEK ALSO.
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
There is no way to adjust the belt tensioner, if it's not keeping enough tension on the belt the complete tensioner itself will need replaced.
Your Explorer has a serpentine belt tensioner which keeps the proper tension on the serpentine belt unless the tensioner has failed.
To loosen the tension on a serpentine belt on a 2005 Grand Caravan 3.8L, turn the nut of the belt tension pulley to loosen it. Adjust the belt, then tighten the tension pulley by turning the nut in the opposite direction.
If the truck doesnt have a tensioner than you must adjust the alternator
you cant, it has an automatic belt tensioner.. you would have to replace the belt if it has stretched
You don't, it has a spring loaded tensioner, If the serpentine belt is loose the tensioner has failed and needs to be replaced
you dont, it has a spring loaded tensioner
Tension is automatic. There is no adjustment.
If it is a serpentine belt, the tension is automatically adjusted by the tension idler. If the belt is loose then the tensioner needs replacing. If it is a normal drive belt, then the alternator is mounted on a slotted bracket that allows you to adjust the position of the alternator. You can loosen the bolts and adjust the tension on the belt.
you do not adjust a serpentine belt. the adjustment is done automatically by the tension pulley if belt is loose, purchase a new belt . also check that all pulleys are in good shape before installing new belt
The belt tension should adjust automatically. There's a thing called a belt tensioner that has a strong spring in it (you can't see the spring) that keeps pressure applied to the belt. This belt tensioner is what makes the serpentine belt so hard to remove. Many times the tensioner is in a difficult place access.
should have spring loaded tensioner nonadjustable
how do i find the auto tension release for the serpentine belt on a 2004solara
The tension on a serpentine belt is automatically set by the Idler Tension Pulley. If you find it is not correctly setting the tension, the the spring may be broken.
you don't tighten a serpentine belt the tension is supplied by a tension pulley if belt is loose, it is time to replace belt or tension pully if tension pully needs repplacing belt will be worn anyway
No need to, it is done automatically thru the belt tensioner. If you suspect the belt is loose you may want to replace the tensioner and possibly the belt.
Most serpentine belt systems have a self adjusting tensioner.
The zd30 has a hydraulic tensioner using an idler pulley to automatically tension the serpentine belt.
You cannot adjust the tension on this, it has a spring inside of it. If it is weak, it must be replaced.
Should automatically supply the proper tension for the serpentine belt - if not could be defective and require replacement
there is no adjustment for tension on a serpentine belt because there is a spring tensioner the belt goes around and if it is sticking and not keeping the belt tight enough you will have to replace the tensioner. They probably cost more than the labor to do it.
No, the serpentine belt is used to drive more than one thing and tension is automatically adjust by way of a spring loaded idler pulley. Normally it will drive the alternator, power steering pump, & A/C compressor. A drive belt normally drives only one thing and tension is manually adjusted. A serpentine belt is wider that a drive belt and is not a V-Belt like a drive belt.
The alternator is rotated on it's pivot to adjust belt tension.
