A faulty timing belt has to be replaced, and the sooner the better. The best course of action is also to replace the tensioner at the same time. Timing belts can become damaged due to excessive wear as a result of old age, or because of contamination from water or oil leaks. If a new belt is over-tightened, it could fail prematurely, or even break. When that happens, the broken timing belt can also cause neighboring components to fail.
If the belt looks worn or damaged, it needs to be replaced. When the timing belt is replaced, other parts, including the tensioner, should be replaced at the same time. This is because these components wear out at essentially the same rate as the belt. For instance, the tensioner bearings could dry out or even seize. It would be a shame if you had the timing belt replaced, only to have a tensioner seize and throw the belt off its pulleys.
When you replace the timing belt and tensioner, your mechanic may also recommend replacing the idlers and the water pump. You could replace the belt and tensioner, only to have the water pump go shortly afterward. Then the belt and tensioner are going to have to be removed to get at the water pump, and that can be more costly than simply replacing it at the same time as the belt.
To reiterate, have the timing tensioner replaced at the same time as the timing belt. And also have any other parts replaced that are associated with the timing belt. That way, you can be assured of many more miles of worry-free driving.

The belt can break due to a number of reasons, but the most common is age.Twitch change game title command
One other common problem is the belt tensioner. If the tensioner is bad, it can cause the belt to come loose or cause the pulley to seize, making the belt come off. Knowing some of the signs of a bad belt tensioner can help you to prevent serious engine damage due to a timing belt failure.
The timing belt tensioner is used to do just that - keep tension on the timing belt. The timing belt is a rubber belt that runs over and through a series of pulleys and gears. Over time, due to age and heat, the belt will stretch out.
As the belt stretches it can become loose, so the tensioner needs to adjust the belt as needed to keep it tight. There are two main types of belt tensioners.Verset pour souhaiter joyeux anniversaire
When a timing belt tensioner fails, it can result in a number of different symptoms. Symptom 1: Squealing, rattling, or chirping. When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. Symptom 2: Knocking or slapping. If the tensioner is not keeping the belt tight, the belt can come loose and hit various parts inside of the timing cover, including the cover itself. This can cause a slapping or knocking noise.
Symptom 3: Check engine light illuminated. Though noise is the most common symptom, a loose timing belt can also cause a check engine light. The check engine light can come on and set a code for a valve timing problem.
This is because the valve timing can become out of sync due to the belt not being tight. Having all of the necessary materials prior to starting the job will make it go more efficiently.Gm parts delay
If you are going to replace the tensioner, it is also a good time to replace the timing belt and the related parts. Since there are many other parts located at the front of the engine that can make similar noises to a failing tensioner, it is important to isolate the noise.
You should remove the serpentine belt and start the vehicle and see if the noise remains the same. If the noise goes away then the noise is coming from one of the engine accessories. Step 2: Open the hood and locate the serpentine belt. The belt will be on the front of the engine.Not impossible, but unlikely. It could be many things, but the timing belt is pretty far down the list. If the timing belt breaks the engine will stop running, regardless of where you are or how fast you are driving, and it will NOT restart no matter what you do.
Whether this car has the 1. However, it will strand you, and if it snaps while you are on the highway in the midst of 18 wheelers, the loss of engine power, power steering, and brake boost could be…very bad. The engine works, sounds, and smells normal right up to the milisecond after the belt snaps.
However, I guess that if the belt was beginning to shred, it is possible that you might smell something. If you are a bit of a gambler, then you can drive it, but I suggest that you take local streets rather than highways just so that you are not driving at more than mph if the belt snaps.
This is one case where local driving would be preferable to highway driving, simply because of the highway scenario of having to dodge trucks while you have no engine power, power steering, or brake boost. It sounds to me like a clutch issue-- maybe the hydraulic clutch system if so equipped is losing pressure.
It could be a fairly simple hose or cylinder. Check the engine oil, transmission fluid level, and coolant in the radiator. Check these things before even starting the engine again. Just as I got to work and was turning to down a street to park, the engine abruptly stalled it had been idling at a light in first, with the clutch in and it took me several tries to get it going again.
Is it Necessary to Replace the Tensioner With the Timing Belt?
Mike makes an excellent point about the timing belt being intact at this point. Have it towed to a reputable independent garage and fix whatever needs fixing, including the timing belt, tensioner and water pump.
There is a guy in my neighborhood who drives an older Celica with 1. He got it from his brother in Nevada where it was used a great deal in the dry desert. The original white paint still looks OK and the engine has never been rebuilt!
I only haveon my old Accord. Now I have something to shoot for. Well look dude. Maybe the timing belt has slipped a notch. Or maybe any of a dozen other possibilities.The timing belt tensioner is part of the internal combustion engine of a vehicle, and it is responsible for keeping the timing belt moving at a consistent pace.
The gear and chain systems that connect the timing belt to the crankshaft or camshaft will not work properly if the tensioner is worn, cracked or torn.
Since the timing belt and tensioner are difficult to inspect without removing them completely, you will need to listen for specific noises to determine if there is a problem with the timing belt tensioner. Listen for a rattling noise.Juwata jazz solemba mp3
A rattling noise when you start or accelerate could be an indication that there is too much pressure on the tensioner pulley, or that it is cracked. Listen for rapid changes in rpm when you accelerate at low speeds. If the tensioner is not working properly, it may be very difficult for the car to pick up speed smoothly.
Check for oil leaks. If you notice signs of oil leaks within the engine around the camshaft or crankshaft, the tensioner could be cracked and is leaking grease into the engine. Listen for an inconsistent humming noise. Intermittent humming may be a sign that the tensioner bearings are worn or torn.
Listen for squeaking or screeching when changing gears. A tensioner that is under too much pressure will begin to screech or squeal when shifting gears; this could be an indication that the tensioner is worn out and needs to be replaced.

Tip Tensioner bearings are sealed permanently, so there is no way to clean or inspect the tensioner bearings once they have been installed.
Most mechanics will replace the timing tensioner when replacing the timing belt. Warning If a tensioner bearing is failing and begins leaking grease, it will deteriorate rapidly. About the Author This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information.A belt tensioner is utilized in different parts of the automobile engine, such as the serpentine belt.
The main purpose of any belt tensioner is to tighten the engine belt, allowing the belt to energize congruent parts of an engine, such as the serpentine belt to the alternator. Belt tensioners lose strength over time and a driver might begin to notice several signs that a tensioner is going bad.
The fluttering is a sign that the belt is moving too easily in the engine, indicating the tensioner is too loose. The tensioner and the belt might need to be replaced. Any noise that sounds like a squealing, whirling, or chirping might be a sign that the tensioner is weakening.
The pulley bearings should be ruled out first because loose bearings can also cause such a noise. If the noise is coming from the tensioner, it is time to replace it. If the battery light goes on and off during the start up of the car or while driving, this can be a sign that the tensioner is weakening.
A normal tensioner speeds the belt enough to keep the alternator on, powering the car battery. A loosening or weak tensioner causes a belt, like the serpentine belt, to slow down or slip out of its normal compartment in the engine. The car battery light will go on when this happens. When inspecting the engine, if rust or dirt are built up around the tensioner, it is probably time to replace it. Rust and dirt build-up wears out the strength of the tensioner.
Worse yet, rust tends to distribute onto other parts of the engine, such as the alternator, causing further engine damage. Routine maintenance checks can determine if the tensioner needs to be replaced. While the engine is cool, the driver should use torque on the tensioner and spin it in the direction the tensioner spins in when the engine is on.
If the tensioner is not spinning smoothly or if it moves in segments, then a replacement tensioner should be considered.

Also, when your timing belt is loose, it will cause some drivability issues usually under high load or high rpm. If your timing belt is not properly tensioned it will not keep the valves timed properly to the lower end and this will cause misfires, loss of power, bucking, and could even cause a no start condition.
If the car runs, then stand on the side of the car where the pulleys are and try to distinguish where the noise is coming from. If you hear the noise coming from the front of the engine and it is not coming from your accessories, you may hear the belt flapping around due to the loss of tension. If the car doesn't run and you are going to be the one doing the work, then remove your front accessories enough to get to the front cover. Once done, remove the front cover and check to see how loose the belt is.
There should be a little slack on the opposite side of the tensioner, but not much. With the cover off, check for the free movement of all the idler pulleys and the tension itself. It will be very apparent if something is broken. While you are in there, it is smart to just get a timing belt kit and replace all the pulleys and the belt.
Make sure that you line up all your marks and set the proper tension on the belt. I have had to change my timing belt twice within a year. What could be the cause? First, check that none of the teeth that the belt is riding on are worn. Worn teeth will dig into the belt and cause premature wear. Then, check each gear's bearing. The belt tensioner bearing is the most likely one to fail first, but it's usually the easiest to check and fix.
With the belt off, spin the belt tensioner which is usually the plain, smooth wheel on a spring loaded arm; the smooth side of the belt rides along it.
Finally, check for rubbing. See if anything is rubbing against the belt, causing it to fail.Some forums can only be seen by registered members. If it fails completely it could cause more damage and strand you in a dangerous position. I would not ignore the advice. Change it. Should be small potatoes to an Audi owner, right?

Messing that job up would be very difficlult. Omaha Rocks.
