How do you replace the serpentine belt in a 2006 Ford Taurus?

Honestly, you really cannot do it by yourself, it is most likely hidden among all the useless equipment in cars of this era.

Not True!While I concur these belts are typically hidden amoung the 'useless accessories' like alternator and are in seemingly tight spaces; Honestly You Really CAN do it yourself!

Replacing the serpentine belt (aux drive for alternator, power steering, water pump, A/C, etc.) on any vehicle simply takes patience and a little mechanical aptitude.

Don't be afraid to go for it if have:

What size is the serpentine belt for a 2004 Ford Taurus 3.0L SFI with no air condition as the factory does not make or provide this belt size ie not in store info?

Route a long piece of string as the belt would be routed. Pull it taught, then tie it off. Cut the string and measure it.

Most brands of belts are supplied in sleeves that explain the relation between belt size in length. Consider that you need a belt one size SHORTER than your string, as the tensioner was not loaded when you tied the knot.

I just measured my car with out the ac comp. It was 82 1/2 inches. I bought a belt size 81.75" from a AutoZone. Works perfect. Just no AC! Had to remove the water holder for the Radiator to install Belt.

How do you change a serpentine belt on a 1999 Lincoln Navigator?

It is actually pretty easy... You need a Serpentine Belt Tool that can be borrowed from a local auto parts store... (Discount Auto lent me mine)... Use the tool on the tensioner to loosen up the belt for removal. (The tensioner is in the center of all your pulleys about mid vehicle) {Mine has a identification diagram on panel above radiator} Once loose enough the belt should slide forward and completely off. Just put the new one on in reverse order {Mine shows a diagram of path on panel above radiator}. And your done!

How do you bypass the ac compressor on a 1993 ford thunderbird lx v6 with a serpentine belt?

If the compressor is in the path of the belts you will need to remove it. If it is outside the path you can simply replace the belt with a smaller belt. Serpentine belts are sized by their number of grooves and length. For example: a 50.5" circumference belt with 6 grooves wwould be : 6K505 or a variation of that. Take a wire and run it along the new belt path to get a idea for the length and count the grooves. Good luck! You would have to get a shorter belt. Why do you want to bypass it? Just unplug the compressor clutch or pull the fuse and use as is. The clutch will not engage and there will be no drag on the engine.

Why does the AC squeak when it is running in a 1998 Nissan Altima?

Could be the belt needs adjusting. While, hopefully, answer 1 is correct, it is also possible that a bearing or other component INSIDE the compressor is worn, and beginning to "gall." Also, that first answer is assuming that the squeaking sound is coming from the compressor, belt, or pulleys. It is also possible that the bushings [bearings] in the BLOWER motor are galling.j3h.

How much will it cost to replace the transmission in a Nissan Quest?

instead of having it replaced you best bet if you don't want to pay that much is to go a junk yard, they have good ones, and then just have someon put it on for a couple hundred, because i had a Nissan stanza and just replace the damaged parts and labor was about &2000.

Do serpentine belts stretch?

Yes, you can stretch it to put it on and then adjust the tension.

How do you replace the serpentine belt on a 2000 Dodge Dakota V6 diagram?

You need to remove the fan shroud.

Put a 3/8" socket wrench into the square hold in the auto tensioner (the arm with the pulley on the left side of the engine, as you are facing it.)

Rotate the arm with the wrench (counterclockwise, I believe) and slide the belt off. It helps to have another person help you. Before you do it, make a note of the routing of the belt so you know how to install the new one around the pulleys.

When you install the new belt, you have to string it around the fan. It takes a little practice, but eventually you will get it. Once you have it routed around all of the pulleys except one - go back to the tensioner and release the tension again - then slip the belt over the last pulley. (a second person helps.) It is easier if the last pulley you leave is the water pump pulley.

Correction to aboveOn the 1999 Dakota with the 3.9liter, the fan shroud absolutely DOES NOT have to be removed. Very simple job. Simply use a breaker bar with a 15mm socket on the belt tesioner pulley nut. Using the breaker bar push (as though tightening) the pulley nut...the reaction will be that the tensioner removes tension from the pulley and the entire belt can be removed by easily slipping it toward the front of the vehicle...comes right off. The new belt can go back on in exactly the same manner. By the way the belt routing diagram IS CONVIENENTLY LOCATED between the hood latch and the radiator mounting for simple and quick refernce...one person job, I did removal and installation four times in less than 10 minutes. (why four times? The auto parts store was selling replacement belts that were too long and did not allow the belt tensioner to provide suffiecient tension...I had to try four different manufacturers before the tensioner was adequately tight with room to grow as the belt naturally stretches from use.). I found no stringing around the fan is required because of the way the belt is routed (it doglegs around the main engine pulley which is centered below the fanhousing and then the belt runs from there to the left side of the fan housing...avoiding the fan/fanhousing all-together (sure you can try to go past the fan/fan housing if you so desire...but you dont have to...and besides the space between the pulleys and the fan is ample to allow the belt to pass between with minimal interference or a simple rotation of the fan as you attempt this method. One hint that made my installs easy as pie...the last pulley you put it over should not be a bezeled and ridged pulley or you will needlessly make life difficult for yourself...the last pulley should be the water pump pulley which is a smooth bore and non-ridged pulley (makes you wonder how the belt even stays on it!)...making it easy as pie to slip it right over...as your last act of defiance to that mean old serpentine belt! Added TipOn my 97 Dak, the tensioner pulley has a little stop. If you don't use the breaker bar to push the pulley back to the left after you install the new belt, you won't get proper tension. This is definitely just a 15 minute job, even for a complete novice mechanic. My tire shop (I get free rotations) wanted to charge me $75 for the job. I just laughed in their face.

How do you replace serpentine belt 2000 focus?

Most cars and trucks today have what is called a serpentine belt which runs most accessories.They are very dependable and usually easy to replace. To decide if your belt needs replacing, simply look at the grooved side of the belt to see if it is cracking badly. A couple of cracks every 3 inches is normal, but if you see cracks every 1-2 inches I would recommend that you replace it. On most cars and trucks the procedure is basically the same. First off, get the correct belt by bringing your cars VIN number to the parts store(located on your cars dashboard) the parts store may need it. If there are two choices, get them both so you can complete the repair. Once you have the correct belt, take a minute to review how the belt runs across the pulleys and also check to see if your car/ truck has a underhood diagram of belt routing in case you need it. In most cases you will need a socket wrench or breaker bar with either a 3/8" and /or 1/2" head on it and possibly a short extension. Some models may require a wrench of these similar sizes.Now that you are ready to go to work, you will need to find the spring loaded tensioner which is generally located near the top of the belt path; it usually has a shinny pulley on it. Look at the tensioner and insert the tool into it and apply opposing pressure to release the belt.Now, simply install the new belt making sure it fits into the grooves on all the pulleys. Start the car to check it and you are done and you saved yourelf some money!

How do you replace the serpentine belt on a 1999 3.0L ford ranger?

Make a diagram of all the pulleys and draw the belt in. Locate the belt tensionor. Loosen it. Slide belt off of the pulleys. Look at your diagram and install the new belt. Tighten tensionor. There should be little play in the belt after being installed on the pulleys.
