Is the water pump pulley suppose to move freely or not w/o the serpentine belt? 2006 Impala 3.9 194,000 miles.

2006 Impala 3.9 194,000 miles. I also noticed that when the engine was running, the a/c pulley was not turning!? Is this 2 separate issues or, is this one in the same? Thanks 4 any help. Update: W/o the belt on the a/c pulley turns by hand but, with the belt on & running the a/c pulley doesn't turn. not the water pump pulley. Update 2: I 4 got to mention, the water pump pulley does not turn by hand w/o the belt on

The a/c pulley is clutched, the ribbed portion( that the belt rides in), should turn freely w/o the belt! With the belt on, the a/c on, and the car running, the a/c clutch should kick in and spin occasionally! The waterpump should have little resistance w/o the belt! Id suggest replacing it if you cant turn it by hand, without the belt!

    Turned engine on & looked @ the a/c compressor pulley & it was locked~!?I'm talking about the pulley not the clutch but, when I took the belt off, I could turn the pulley by hand!?
    Thanks 4 your post & help.

    I thought the a/c pulley is suppose to run with or w/o the a/c on!? Whether the a/c is on or off, the pulley itself will not turn. Only with the belt off.'
    Thanks again.

    Sorry it has been so long, I forgot my log in, just now got that straightened out! Im not sure if im following you correctly. With the belt on, or off, you should be able to turn the a/c clutch/pulley. If it doesnt turn at all, your compressor is most likely seized!

The water pump is going bad should have a little resistance --with the a/c clutch pulley the pulley is two parted with a clutch that when energized will turn as one with the pulley the clutch is the front part and will be hard to turn the pulley where the belt rides should turn freely

The water pump pulley is seized and therefore not allow the AC pulley to move

Inspection

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.


Removal & Installation

  1. Disconnect the negative battery cable.
  2. Rotate the auto tensioner clockwise to release tension, then remove the drive belt.

To install:
  1. Install drive belt (A). Route the belt over the components in the following order: Crankshaft pulley - A/C pulley - idler pulley - generator pulley - water pump pulley - P/S pump pulley - tensioner pulley.
  2. Rotate auto tensioner arm in the counter-clockwise moving auto tensioner pulley bolt with wrench.
  3. After putting belt on auto tensioner pulley, release the auto tensioner pulley slowly.

Need diagram for serpentine belt for chevy imo l s 2003

Click on the following free direct Link. It has the Serpentine Belt Diagram and Tensioner location for your 2003 Chevy Impala.

GENERAL/Standard Rules to Removal the Serpentine Belt with a Tensioner:
A. Find the Tensioner(s). (See Diagrams on Link)
B. 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 the Tensioner Pulley/Arm - 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.
C. Remove the loosened belt off one of the other more easily accessed Pulleys.
D. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

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.

99 Altima with 190k miles warbling noise

It sounds like your water pump is going it usually vibrates throughout everything if it was your alternator it would show signs with your power the easiest way would to take your belt off remembering the belt route and spin the alternator pulley and the water pump pulley to see if they spin freely without noise

Serpentine Belt and pulley were replaced. Drove

High moisture with cheap belts would be a start. 2nd possibility is you have a bearing in an accesory drying out. Check water pump pully first with the screwdriver methode. Do not place on a moving part!!!

Serpentine belt slips off idler pulley

The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.

Serpentine belt

The pulley's aren't supposed to spin freely with the belt on. The belt connects all the pully's to the crankshaft, which does not spin freely because it is attached to the pistons inside the engine. To turn the pulleys, you have to turn the crankshaft, which in turn moves the pistons inside the engine up and down.

1996 Jeep Cherokee Classic with serpentine belt and fan problem or water pump?

Hey Dougnchico,

I'll bet your car died. And it over heated, And the battery was flat
, And the steering went out and every other system run off of the belt.

This is for anybody who has had trouble getting a serpentine belt on. It's easy and doesn't require a prybar.

  • Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
  • Get the belt around all the pulleys except the A/C compressor or Alternator.
  • Locate the tensioner pulley. It's one of the smaller ones and is mounted on a spring loaded arm. It's job, as the name suggests, is to keep the belt tight. Get your socket on the center nut of this pulley.
  • Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
  • Slowly release the tension.
  • You're done
