SQUAK AROUND FAN BELT - 2006 Citroen Xsara Picasso

No, you should be able to fish the belt over the fan blades, one at a time. Follow this:
Step 1 Open the hood. Disconnect the negative (black) battery cable.
Step 2 Inspect the fan shroud for the accessory belt routing diagram. If the diagram is missing or illegible, use a pen and paper to draw your own diagram before removing the belt. The new belt must be routed around the pulleys exactly as the old one was.
Step 3 Locate the spring loaded belt tensioner on the front of the engine. There is a small pulley attached to the bottom of the tensioner arm.
Step 4 Slide the square end of the breaker bar into the square hole in front of the tensioner pulley. Rotate the breaker bar counterclockwise and the entire tensioner will move enough to relieve the tension from the belt. Pull the belt out from under the pulley and slowly let the breaker bar retract.
Step 5 Remove the accessory belt from each pulley with your hands. Rotate one of the fan blades to the top side of the engine with your hand and pull the belt around it. Repeat this process until the belt is around all of the fan blades. Pull the belt out of the engine compartment.
Step 6 Route the new belt carefully around each fan blade. Wrap the belt around the crankshaft pulley to begin the belt routing process. Refer back to the belt routing diagram instructions to properly route the new belt around the accessory pulleys.
Step 7 Turn the tensioner counterclockwise again with the breaker bar. Position the new belt evenly under the tensioner pulley. Allow the tensioner pulley to tighten against the belt. Pull the breaker bar out of the tensioner.
Step 8 Reconnect the negative battery cable.

If there is no diagram pasted in the engine compartment, check your owner's manual...or else go to your local auto store warehouse or Chevy dealership...usually the parts counter person can print out the diagram specifically to your vehicle. Since you did not mention the engine specs- I'm going to generically how to install a serpentine belt.

1.) make a loop and slip the loop around the crank shaft pulley
2.) continue looping the belt around the water pump pulley
3.) ...around the A/C pulley
4.) ...and around the idler pulley
Skip the alternator pulley for now- you want to do that one last.
5.) Continue placing the belt around the power steering pump pulley
6.) and over the belt tensioner pulley
7.) Now move the belt tensioner position so that you can loop the belt over the alternator.
8.) Now double check to make sure that the belt is properly and securely fastened around each pulley's grooves. Don't start the motor until you are absolutely sure... and can visually verify that the new belt is installed properly. And don't have anyone (or pets) standing around the car or open engine compartment when you initially start the car just in case the belt breaks...serious injuries can occur!
I've attached a generic drawing it may or may not fit the description of your auto.

Check with Autozone and discuss your problem. They know what they are talking about and have always come up with the right parts or belts for me. I used to be a mechanic in my youth and I never go anywhere else.........

It is a big process

Open the hood. Disconnect the negative (black) battery cable.

Locate the spring loaded belt tensioner on the front of the engine. There is a small pulley attached to the bottom of the tensioner arm.

Slide the square end of the breaker bar into the square hole in front of the tensioner pulley. Rotate the breaker bar counterclockwise and the entire tensioner will move enough to relieve the tension from the belt. Pull the belt out from under the pulley and slowly let the breaker bar retract.

Turn the tensioner counterclockwise again with the breaker bar. Position the new belt evenly under the tensioner pulley. Allow the tensioner pulley to tighten against the belt. Pull the breaker bar out of the tensioner.

Reconnect the negative battery cable.

Start the engine for five to ten seconds to seat the new belt. Turn the engine off. Visually check that the belt is properly seated around all pulleys.

Instructions

Things You'll Need
3/8-inch drive breaker bar
Metric sockets
Serpentine belt

1 Open the hood and inspect the flat surface on top of the plastic fan shroud for the belt routing diagram. Follow the diagram instructions to route the new belt.

2 Locate the serpentine belt self-adjusting tensioner on the front of the engine block. The tensioner has a pulley on the bottom of the tensioner arm, which the belt travels under. The tensioner can only be rotated from the bolt that secures the pulley to the tensioner arm.

3 Rotate the tensioner in a clockwise motion with a metric socket and the breaker bar to loosen the tension from the belt. Then, pull the belt off the top of the tensioner pulley. Release the tensioner pulley and pull the breaker bar off the pulley bolt.

4 Pull the belt out of the accessory pulleys. Then, slide the belt around each fan blade and out of the engine bay. Rotate each fan blade to the top side of the engine to get the belt around each fan blade.

5 Match both the new belt and the old belt together to make sure that the new belt is the correct size. Then, route the new belt around each fan blade and around the crankshaft pulley. The crankshaft pulley is the big pulley at the very bottom of the engine.

6 Follow the routing directions from the belt routing diagram to install the new belt around the other accessory pulleys. Once the belt has been routed around all of the pulleys, look over the belt and make sure that it is secure inside all of the pulleys.

7 Crank the 1998 Dodge Caravan and let the motor run for about 15 seconds. This will finish seating the ridges of the new belt into the grooves of each accessory pulley.

8 Shut the motor off and close the hood.

it may be your tension pully check it .with the belt off spin it by hand it should spin freely

no just slip belt around fan to install, you may have to spin fan slowly around whil slipping belt over it.

you need a new fan, is it the inside fan for the heaters? or the main cooling fan? is the engine vertical or stright? if its a vertical engine then it will be quite a big belt around the fan, sort this quickly if so, as can cause alot of damage if the belt snaps.

Squak & knock, as in maybe belts squealing due to loose?

it could be the tensioner .or it could water pump.you almost have to take off belt and spin by hand the individual pulleys. also wile fan is still on and truck is off take the fan see if it moves back and fourth front to back it should have no play in it .because it is attached to the water pump shaft.
