Probably only if it's large enough to work it over the fan to start with. You can on some cars, but don't know about yours.

The belt goes to flywheel, radiator cooling fan and alternator. It does not go to a/c depending on what engine configuration.

It sounds like the alternator is not properly lined up. You had the belt on right the first time. Put it back on and before you start the truck check the alignment on the belt. From the side of the truck look down thw belt to the fan pulley and see if you notice a slight bend, or use a straight edge to do the same thing. Also sight down the belt to the crank for the same thing. Yoiu may have to shim out the alternator brackets to get the belt in line with the other pulleys. Hope this helps.

How do I intall a new fan belt on a 2004 envoy. I am not sure witch way it goes around the fan


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.

Try slipping the drive belt (fan belt, alternator belt, or whatever you want to call it) off the engine, then run the engine momentarily without the belt. If the noise disappears, at least you now know it is not an internal engine problem, and it will be an issue with one of the pulleys, or belt-driven accessories.

Fan belt came loose...how to tighten?


it does not have a fan belt, it has a serpentine belt. the radiator fan is electric. if the serpentine belt is loose, means your tensioner's spring has lost its strength, you need to buy a new tensioner. they are about 50 bucks at autozone or advance. if you look around under the hood you will find a little picture of the belt, and a wrench being applied to the tensioner in order to remove the belt. get a new belt while you are at it. in the real world you are going to take off the right front tire and remove the service access panel behind it which will expose the bolts to remove the tensioner and allow you to put the belt around the crank pulley. it could be done without removing the access door, but unlikely. there is a motor mount there also, called a dog bone. if it has never been replaced before, this would be a good time to do that as well. they are about 18 dollars each. when you have that under your belt you can go hog wild and replace the dog bone on the other end of the engine, under the battery holder.

Alternater change belt release


Hi and Welcome to Fixya

Here's how to replace the belt.

1
Disconnect the battery ground cable and lay it aside, ensuring that it does not touch metal. Unplug the wiring harness connector on the back of the alternator if so equipped. If you can't pry the plug tangs open with your fingers, use a screwdriver.
2
Remove the nuts on the back of the alternator with a wrench then pull the wires off the studs. Loosen the accessory drive belt tensioner with a socket, by pushing the tensioner towards the engine. Lift the belt off the pulleys.
3
Unbolt the alternator mounting bolts with the appropriate socket then remove the alternator.
4
Fit the new alternator onto its bracket then insert the mounting bolts. Tighten the right bolt to 18 foot-pounds of torque then tighten the left bolt to 37 foot-pounds of torque. Route the accessory drive belt around the pulleys, except for the tensioner pulley. The drive belt routing diagram is located on the fan shroud or the inside of the hood. Push the tensioner towards the engine. Slide the belt on the tensioner then release the tensioner.
5
Plug in the wiring harness connector if so equipped. Slide the wires onto the proper terminals on the back of the alternator. Tighten the battery feed wire nut to 71 inch-pounds of torque. Reinstall the negative battery cable.

Have a good one!

Replace alternator


The alternator belt on the 1999 Dodge Caravan also controls the air conditioner compressor, the water pump and the power steering pump. The belt is called a serpentine belt, and it is designed to fit around all of the accessory pulleys at the same time. As the belt travels around each accessory pulley, it enables the accessory to operate. Once the belt is damaged, cracked or frayed, you should change it before it breaks. If that happens, each of the accessories will stop working.

Open the hood and prop it up so that it does not fall. Engage the parking brake.

Inspect the top surface of the fan shroud for the serpentine belt routing diagram. Follow the routing instructions on the diagram to install the new belt.

Locate the serpentine belt self-adjusting tensioner on the front of the engine. The tensioner is directly below the alternator. Use the bolt that connects the tensioner pulley to the tensioner arm to rotate the tensioner.

Turn the tensioner device counterclockwise to move the tensioner. This will relieve the tension from the belt. Once the belt has enough slack in it, slide the belt out from under the tensioner pulley.

Lift the belt off each accessory pulley. Slide the belt around the fan blades and out of the engine area.

Lay the old belt next to the new belt to ensure that the new belt is the correct width and length. Slide the belt around the fan blades and around the crankshaft pulley on the bottom of the engine.

Follow the belt routing diagram to position the belt around the air conditioner compressor pulley, the power steering pump pulley, the water pump pulley and the idler pulley. Once the belt is routed inside each accessory pulley, inspect the belt to make sure that it is securely inside the pulleys.

Crank the 1999 Dodge Caravan for 10 to 15 seconds to completely seat the belt ribs in the grooves on each accessory pulley. Shut the engine off and close the hood.

If the belt routing diagram for the 1999 Dodge Caravan is missing, use a pen and a notepad to draw the exact routing of the old belt and use it when installing the new belt.
