The tension spring is broken, and the entire assembly must be replaced.
Install a new tensioner pulley. If a serpentine belt is loose then the spring in the tensioner pulley is probably weak or the tensioner pulley is hanging up on something. Have fun! Chris
it is a spring loaded pulley that keeps a constant pressure on the belt
If your car has a serpentine belt it will have a tensioner pulley. A tensioner pulley is easy to spot. All of your bolt on accessories i.e. water pump, alternator, a/c compressor etc. will have a pulley to run each one. There will be 2 other types of pulleys, a idler pulley and a tensioner. The idler pulley will be a single stationary pulley with a bolt going through the middle and the tensioner pulley will be on a spring loaded piviot.
a spring loaded
There should be a spring loaded tensioner pulley. If the pulley isn't holding the belt sufficiently tight you may need to replace the tensioner.
You don't. The tension on the belt is held tight by a spring loaded tensioner idler.
pulley tensioner replacement%ford ranger xlt 3.2l 2wd instructions. do use an ALLEN wrench to loosen the spring or is it a special tool
No, tensioner pulley is at a preset tension, no adjustment can be made. If there is slop in the belt, the spring loaded tensioner should be replaced.
No you can not, It is kept tight by a spring loaded belt tensioner with a smooth pulley on it. Probley needs a belt tensioner on it.
Remove the belt, then remove the bolt in the center of the spring tensioner with a 15mm wrench, install new one
as new as the car is it would have a belt tensioner pulley...its a pulley with a spring loaded pulley to self tightn the belt...if u take the right size of socket for at the pulley and turn the pulley down...but not by unscewing the bolt at the pulley...by using the bolt as something the to hang on to the pulley so when u turn it the pulley will retract and losen the belt to take off...very easy but takes some muscle....if it doesnt have a belt tensioner pulley it would be the alternater that will have to be moved so the belt losens....if that's the case have when u put the new belt on you have to make sure the belt is tight enogh or to tight....the belt will have play in it but with strong applided movement...also the serpentine belt doesnt have to be timed
pretty much-the 2 get confused all the time. Technically a tensioner is an assembly with a spring and an idler is a fixed pulley-most newer cars have both.
