Hello, thank you for writing in. There are a few things you need to look into. One, have you been buying the same brand of tensioner, and have they been warrantied? You may want to make sure you are getting a higher quality tensioner to begin with, or at least make you can get your money back for them. Secondly, you should make sure that the mounting bolts are not stripped or loose allowing the tensioner to rotate or move. It needs to be secured tightly. There are other pulleys in the system that the drive belt depends on. Make sure the idler pulley, and all of the other pulleys connected to the respective components are working as designed.

The tensioner is located on the outside of a serpentine belt which is the smooth side of the belt. It puts tension on the belt to keep it tight. The serpentine belt stretches over time, so the tensioner puts more tension on it to keep it tight. A broken tensioner might click or squeal.
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.
The serpentine belt goes by a couple of different names: accessory belt and drive belt. The belt is long and snakes through several pulleys. That`s why it`s called a serpentine belt. You can find the serpentine belt on the front or side the engine.
Tensioners can be divided into three general categories; fixed, adjustable, and automatic.
The main physical difference between an idler pulley and tensioner pulley is a simple adjustable bolt! However, in terms of function and purpose, an idler pulley is responsible for guiding a belt drive in an engine or mechanical system, while a tensioner pulley is responsible for tensioning the drive belt.
The drive belt tensioner powers the crankshaft pulley to the water pump pulley, which is engaged and disengaged by an electric actuator. All this innovative system results in less mechanical loss during the disconnection phase of the water pump.
We find two types of chain tensioner: hydraulic tensioner and mechanical chain tensioner. The tensioner ensures the correct and necessary tension of the timing chain that surrounds the crankshaft sprocket and the camshaft sprocket.
A V-belt is a wedge-shaped belt manufactured out a rubber compound, reinforced with a tensile cord specifically engineered to transmit power into movement. V-belts can be found in driving mechanisms, such as engines in air compressors, fans, and pumps.
Each engine accessory (e.g. the air conditioning, power steering, and so on) has a pulley. The serpentine belt acts as a connection between these pulleys to the rotating engine crankshaft.
A seized or loose drive belt tensioner can cause the belt to snap, which will disables those accessories and can cause problems such as overheating, a dead electrical system and battery, or a disabled AC system.
Loosing the serpentine belt should not affect the engine timing.
There are a couple of factors influencing the answer to this question, but on average, your car should be able to run between 20-90 minutes with a broken serpentine belt. The engine will overheat faster without a functioning cooling system on a hot day, so your driving window is less.
In this case, the driver A pulls the belt from one side (i.e. lower side RQ) and delivers it to the other side (i.e. upper side LM). Thus the tension in the lower side belt will be more than that in the upper side belt.
There are three main types of belt tensioners found in the replacement auto parts market. Each one works a little differently, but all ensure that your alternator and auxiliary pumps receive the power needed to keep your car or truck moving.
Tensioners, idlers and dampers work together to synchronise the timing belt`s rotations in your engine. While tensioners prevent slackness in the timing belt, idlers route the timing belt around ancillary features, and dampers work with the idlers to prevent the timing belt from coming loose.
Idler pulleys are produced in a variety of styles such as, V-belt, plain, flat, and cable style. V-belt idler pulleys are designed for strength and durability. The use of radial supporting ribs provides additional belt support and prevents groove deformation.
You should expect to replace your belt tensioner in the 40,000-70,000 mile range. It is also customary to swap more than one part simultaneously, usually a worn-out pulley from other systems and even the serpentine belt itself.
The primary function of a belt is to transfer power (rotary energy) from one source to another. Whereas pulley that has a groove around its circumference allows a belt to smoothly through it when transmitting rotational motion.
The rule of thumb is to add 1½ to 2 inches to the inside circumference measurement. Our setup demanded a belt between 57½ and 58 inches in length.
Tensioners can be either static (fixed) or dynamic (moving) in operation. A static tensioner means that the tension is set and the tensioner fastened into place to keep that specific tension against the belt during drive system operation.
Tensioning pulleys of the chains or a sliding block are attached to the lever with a screw. It is a universal flexible element that can simultaneously perform the functions of suspension, guidance, tensioning and damping.
Belt manufacturers recommend that the tension ratio for a system with 180° of contact on each sheave should be no tighter than 5:1 (when a new belt has been installed) and no looser than 8:1 (after the belt has run-in).
Standard V-belt pulleys SPZ, SPA, SPB, and SPC are used for classic V-belts 10, 13, 17 and 22. These pulleys can actually be used for all kinds of classic V-belts, narrow V-belts and raw-edged belts with inner cogs.
But, auto manufacturers began to favor the serpentine belt over the V-belt because the former is lighter and easier to place back on track. The latter is heavier and more difficult to install. Plus, the flatter design of the serpentine belt provides greater traction, which generates more power for your engine.
