Is a serpentine belt and drive belt one in the same?

Technically,Yes. But realistically no. They are both drive belts, but the term drive belt is normally what is referred to as a non-serpentine belt. This term is used to distinguish between the two type belts. A drive belt tension must be adjusted manually, whereas a serpentine belt tension is controlled by a tensioner.

with a 1/2" rachet or breaker bar placed in the square whole on the tensioner pully, you push (from passenger side to drivers) which will release the presure on the belt. Might want to draw a "map" of how the belt goes cause it ain't obvious when its off the car.

Why does the serpentine belt keep popping off on a 2001 zx2?

My '99 did the same thing. First time, it was raining really hard, got it towed to a garage. Mechanic said sometimes they will do this in heavy rain, and just put the belt back on ($70)! Second time, I drove over a medium to large sized puddle, and off it went. I was able to drive it home, and put a new belt on. The old one was a tiny bit stretched. Belts are only good for 3-4 years, so maybe that is the reason. Or, it could be: too loose or too tight, or your pulleys are not in-line.

good luck!

What is the difference V belts 4l vs b belt?

The specification of "4L" indicates that the V-Belt is 1/2 inch wide at the top. This is the same as the specification "A" in terms of width, and in fact "A" specification belts are often interchangable with "4L" specification belts in terms of size - however, the composition of the belts and the effective duty rating may nonetheless be different. The "4L" belts are designated as light duty industrial or lawn and garden, and are often found on lawn tractors. They are typically 5/16 in cross section (height), as compared to the 11/32 inches to 13/32 inches for the "A" specification. On the other hand, the "B" specification V-Belt is a larger belt in both dimensions than the "4L" (this was the premise of the question). It is 21/32 inches in width by 7/32 inches in height. It is not interchangable with either the "A" or the "4L" belts. However, it is roughly the size of the "5L" belts, which is the same width (or sometimes 20/32 inches), but slightly less height - 11/32 inches. The specifications relate to design stress placed on the belts (i.e. the horsepower of the drive motor, the requirements of the driven device, the pulley ratios, etc.). Although many people use the "4L" in place of the "A", or use the "5L" in place of the "B", I cannot imagine doing so merely to save a buck or two (literally). Bottom line, it is my recommendation that one stick with whatever the manufacturer specifies for the product. Otherwise, the manufacturer will likely have a good defense to any failures associated with the subject system (i.e. when the belt fails and your widget breaks or you get injured by a flying belt that is not strong enough for the job).

How do you replace the alternator belt on a 1985 Ciera?

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 release the tension for a serpentine beltin an Isuzu Rodeo?

Don't know what year you have but try this:The tensioner is located above the alternator.

If you don't have the Allen wrench, use any 15mm wrench instead at the tensioner pulley nut to achieve the same.

How do you replace the drive belt on a 2000 Nissan Altima?

There are two belts on the 2000 Altima, the A/C compressor belt and the main belt. Remove the A/C belt first by loosening the nut in the middle of the idler pulley (the pulley below the compressor) and then loosening the tension bolt on the bottom of the idler pulley until enough slack is in the belt to pull it off. Remove the main belt by loosening the alternator which acts as an adjustable tensioner. Loosen the top and bottom bolts first then lossen the tension bolt until there is enough slack to remove the belt. To install new belts follow these instructions in reverse. Tighten the belts to about a 1/4" deflection and be sure to tighten all bolts. Notes: The lower dirt shield under the car may have to be removed first to gain access. Make sure to note the position of the belts through the pulleys before you remove the old ones. There may be a diagram under the hood of the belt route to use for a reference.
