What size serpentine belt do I need?

With the measurement made, subtract 5/8-inch (16mm) from the length to compensate for the position of the loaded tensioner and that's your belt length. To convert the inch measurement to millimeters, just multiply the length in inches by 25.4. As an example, if the belt measures 66 inches: 66 x 25.4 = 1676mm. via

Do serpentine belts fit all cars?

Today, there's one belt to run them all—well, for the majority of vehicles. It's called the serpentine belt. Some rides may have an additional belt to run select accessories, but the serpentine does the bulk of the work. via

How do you find the belt number?

Automotive belts start with either 4L (12.5mm wide) or 3L (9.5mm). The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2" less for a 4L belt, and 1-1/2" less for a 3L belt. An example would be 4L460, which would be 46" long outside, 44" inside. via

Are all serpentine belts the same?

Every car engine is different, even engines from the same auto manufacturer. That means the serpentine belt will snake around the pulleys in a different order too. Newer cars might have a plastic covering over the engine that will need to be removed in order for you to see what's going on with the belt. via

How do you size a pulley belt?

    Can you bypass the AC with a serpentine belt?

    The compressor cannot be bypassed without the use of a compressor bypass pulley. It would cost more for a bypass for the compressor than it would be to just replace the compressor pulley. Install a new pulley or pulley bearing if it can come off of the compressor and then put on a new belt. via

    How do you buy a serpentine belt?

    Get the right size: If your old serpentine belt no longer has a part number on it and you can't find a manual for your vehicle, slip off the old belt and use a string to measure its length. Then order one size smaller than the string, to make up for the stretching of your current belt that has occurred over the years. via

    What happens if you use the wrong serpentine belt?

    Bad Serpentine Belts Cause Vehicle Performance Issues

    The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly. You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt. via

    Can a serpentine belt be to tight?

    If the belt is too tight, it will cause excessive side loads and overheat the bearings. This in turn causes noise, decreased output and even the seizing of the alternator. If the belt is too loose, it will cause the alternator to slip. This slipping can cause the alternator and the battery to work harder. via

    Does a serpentine belt stretch?

    Serpentine belts stretch with age and use; as time goes on, the rubber becomes dryer and less pliable making cracking more prevalent. However, cracking can also be caused by a defective tensioner. via

    Do I need to replace tensioner with serpentine belt?

    Tensioners add pressure from an adjustable pivot point or spring mechanism to keep your serpentine belt taut as it circulates around the engine. There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does. via

    What is a 5L belt?

    5L Belt = 5/8 (.625) Inches Width x 3/8 (.375) Height. 3V & 3VX Belts = 3/8 (.375) Inch Width x 5/16 (.3125) Height. 5V & 5VX Belts = 21/32 (.65625) Inches Width x 17/32 (.53125) Height. via

    What belt do I need for my car?

    There are two belts you need to be familiar with when talking about car maintenance — the serpentine belt and the timing belt. The serpentine belt winds through your engine and carries power to several key components, including the alternator, air conditioning, and power steering pump. via

    What are 3 types of drive belts?

    There are three basic types of power transmission belting: flat, V, and synchronous. via

    Why does my serpentine belt squeal?

    Worn/Cracked Serpentine Belt – Serpentine belts have grooves which fit into grooves in the pulleys. Over time, the friction wears down these grooves, resulting in a loose fit. A worn belt can, therefore, begin to slip, which is one of the causes the squeal. Alternatively, cracks can cause the belt to snap. via

    Does a smaller drive pulley increase speed?

    Pulleys of Different or Same Size

    If a smaller pulley turns a larger one, the larger one will turn slower, but with more power available at the shaft. If a bigger pulley turns a smaller one, the smaller one will turn much faster than the bigger one but with less power available at the shaft. via

    How do you find the diameter of a pulley?

    Step 4: To determine diameter of pulleys. Step 5: Standard pulley diameters: d = 280 mm and D = 450 mm (OR) d = 250 mm and D = 400 mm can be selected. For this problem, d = 280 mm and D = 450 mm is selected.
    ...
    Step 7:

    C min = 0.55 (D + d) + T
    C max = 2 (D + d) = 2 (450 + 280) 1460 mm

    Can I use a shorter belt to bypass AC compressor?

    Yes, this is possible. However, unless it was the AC compressor clutch and pulley which failed, bypassing the AC pulley is unnecessary. Simply disconnect the wire to the AC compressor clutch and that should do the trick. via

    Can I use a shorter serpentine belt bypass AC compressor?

    Can you Bypass the AC with a Serpentine Belt? Yes, you can bypass the AC compressor with a serpentine belt. via

    Can you drive with a locked up AC compressor?

    Your car is not safe to drive since the air compressor is operated by the same drive belt as the remainder of the engine (serpentine belt). Because the AC compressor has seized, this could cause the belt to lock up other components resulting in major engine damage. via

    How many years does a serpentine belt last?

    Under ideal circumstances, you'll get anywhere from 50,000 to 100,000 miles of reliable service from a typical serpentine belt. In terms of years, it may be anywhere from 4 years to an entire decade before you'll need to replace your serpentine belt. via
