When to replace a faulty timing belt tensioner?
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.
How do you adjust the tension on a serpentine belt?
Locate the adjuster bolt on the belt tensioner used to secure the serpentine belt, and adjust the tension by loosening or tightening the adjuster bolt with a racthet and socket while you simultaneously move the belt back and forth gently to find the proper tension.
What does the pulley on a timing belt do?
Everything is mounted on the base in the spring is what is used to keep things pulled tightly in place. The pulley allows the belts to move as necessary in the system and the tensioner arm is a counterbalance to the spring allowing the timing belts to move and adjust as necessary.
Can a loose timing belt cause a check engine light?
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.
When to replace timing belt and tensioner bearings?
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.
Why does my timing belt keep stretching out?
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.
Why is my belt tensioner not working properly?
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.

What happens if your timing belt comes loose?
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.
What happens when a belt tensioner goes bad?
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. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise.
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.

Can a bell tree be replaced without a tensioner?
Without the tensioner arm you wouldn’t be able to pull the bell tree to replace it with a new one. Usually we hear of the timing belt itself going bad and needing to be replaced, it’s possible that the timing belt tensioner is the problem when your engine and it can be replaced separately from the timing belt if it’s not doing his job properly.
What causes the timing belt and idler to fail?
Misalignment of the timing belt can cause premature failure of the idler pulley or the pulley on the tensioner, as well as the belt. Generally, this indicates that the tensioner or idler is not attached to the mounting location on the engine correctly or the bearings for the tensioner, idler or both, have worn and have excess “play”.
When did the first timing belt come out?
Originally made of a band with metal clips this proved to be expensive and noisy, in 1945 Singer in conjunction with Uniroyal which is now Gates Inc. developed the timing belt. Now to all you guys from the 50’s and 60’s typically every engine had a timing chain.
How do you remove a timing belt from a car?
This tensioner may be an automatic hydraulic type that you simply crank in one direction to remove the old timing belt. Or, you may have to loosen the tensioner pulley adjustment bolt to release the tension and the belt. Before proceeding, confirm which way the engine rotates during normal operation.
Is it necessary to replace the tensioner with the timing belt?
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. Additionally, the timing belt’s teeth can develop stress cracks, or even detach. If the belt looks worn or damaged, it needs to be replaced.
Why is my timing belt still working after 500 miles?
After all, they’re belts so they can sometimes stretch to where they want to be without your effort. If the sound is still there in 500 miles, it’s bothering. If it’s there in 1,000 miles, it’s concerning.
What to do if your timing belt is rubbing?
Take the covers back off and look for signs of the belt (s) rubbing against something. That’s what I hear on the clip. May want to recheck belt tension. Run the engine with the belt cover off to double check before buttoning everything back up.
Can a timing belt be changed on a Honda Goldwing?
Well, I was finally able to pick up my new-to-me Goldwing this past Saturday. I started off with the first thing recommended by many and changed the timing belts. I followed the recomended and provided instructions to the letter. I still feel however that the tension is not right. At idle speed the bike sounds perfect.
How is the tension set on a serpentine belt?
Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times. If your vehicle does not have a tensioner pulley, the alternator bracket is likely how tension is set on the belt.
Can a bad belt tensioner cause a car to break?
In more severe instances, a bad tensioner pulley can cause the drive belt to break. Since the belt tensioner keeps the proper spinning of the drive belts in the car’s engine, certain components or accessories may fail to operate if there’s a problem with the tensioner.
What’s the best way to replace a serpentine belt?
Auto tensioners have either a hole that will fit a half inch drive ratchet, or a bolt you can use a socket to apply pressure to. Insert the wrench or place the socket over the bolt on the tensioner and twist it away from the belt to relieve the tension on it.
