Check for vaccume leaks and also you PCV valve. check the hose too. Visually inspect every vaccume hose you can find. Sounds like a leak .

That should be right if it is an idler pulley. On belts that do not have idler pulley you will have to loosen lock bolt on adjuster. Like alternator

How do i tighten power steering belt on a 1991 Nissan sentra


This is just a general answer. There are 2 ways to tighten a power steering belt, 1, by adjusting the power steering pump OR 2 by adjusting a tensioner pulley.
Inspect the belt system and see which one your vehicle uses. If the pump is adjustable, it will be mounted on one end by either a sliding bolt on a curved bracket like the alternator, or by an adjusting bolt.
If your car has an adjusting pulley, check the routing of the belt. It will normally run from the front engine pulley over the adjusting pulley then over the power steering pump pulley. The adjusting (tensioner) pulley will have to be loosened, then either pulled to the tightening position by hand and retightened, or else there will be an adjusting bolt and nut which must be turned to tighten the belt before retightening the pulley.
Sorry, I don't know your car that well so my answer is just generic.
Good luck

Idler Pulley replacement


there is normally a spacer on the bolt that positions the pulley the correct distance to miss the mounting bracket. IT sits between the bracket and the inner race of the bearing and locks that race so that the bearing can operate correctly.

How do i tighten belt


My sincere apologies for the severly delayed response.
I am personally going back to answer your unanswered questions.

I do not know if you still need this information, however I am answering it in case you still do.

Click on the following direct Link. It has several Diagrams for your Belt depending on your engine size and options (AC/No AC etc.) AND whether you have Tensioners OR Locking/Adjusting Bolts/Nuts.
IF APPLICABLE: These point out the direction of rotation for the Tensioner in order to loosen and reinstall the Belt.
IF APPLICABLE: These also point out where the Locking and Adjusting Bolts/Nuts are, to loosen the belt and remove; and reinstall the Belt and TIGHTEN.

Standard Rules to Removal the Serpentine Belt with a Tensioner:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating it\moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.


Standard Rules for Installing the Serpentine Belt with Tensioners:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them

Again my apologies...
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.Com!
