What to do when your timing belt makes noise?
Remember the timing belt drive may not be the only source for noise. To eliminate the timing belt as the noise problem, spray it with soapy water while it is running. If the noise goes away or decreases, then the timing belt is part of the problem. If the noise is still evident, then the problem is likely due to other drive components.
What is the frequency of the timing belt?
Meshing frequency is assumed to be the primary frequency of noise generated by timing belt drives since the noise is generated from meshing interference and land impact during operation. Meshing frequency is defined as the number of timing belt teeth that enter and exit the timing belt pulley grooves per unit of time.
Is there a way to reduce belt drive noise?
In addition to design considerations, there are several other accepted methods of reducing belt drive noise: Split Width Timing Belts. Although this method generally results in only very small reductions, approximately 4-5 dB, tests have shown it will help.
Do you need a split width timing belt?
Split Width Timing Belts. Although this method generally results in only very small reductions, approximately 4-5 dB, tests have shown it will help. When using wide timing belts, the drive can be split into two standard width timing belts, i.e., one 170 mm = two 85 mm wide timing belts.

Why does my car engine make a clicking noise?
Engine noises can be hard to trace. Talk with a trusted mechanic to figure out what’s wrong with your car. Rotating parts, like belts or brakes, make grinding or whining noises, but reciprocating parts, like pistons or tire rods, make an annoying ticking or clicking noise during operation.
What causes excessive noise in a timing belt?
Improperly tensioned drives will more likely generate noise. Timing belt tension should not be too high or too low. Too low a tension can also lead to shortened timing belt life or ratcheting, while too high a tension will add undue stress to bearings, shafts and other related components.
What should I do if my timing chain is making noise?
Use a socket and breaker bar to attach to the center bolt on the belt tensioner pulley. Turn it clockwise to unload the belt tension and then slip the belt off the pulley. Start the engine. Use the stethoscope to listen for noise at the timing chain cover.
Why does my car make a noise when I accelerate?
Belt noise can mean the belt is worn or loose. Belt noise can also come when one of the pulleys the belt is riding on starts to fail. When the belt no longer moves smoothly along the pulleys, it makes a noise when the car is accelerating. The other noise you might be accustomed to is that of a loud exhaust system.
How to reduce the frequency of the timing belt?
Minimize timing belt speeds. By slowing down the drive, the noise level is reduced and the frequency of any generated noise is lower. This often puts the frequency of the drive system into that unobjectionable area. Minimize timing belt width.
In addition to design considerations, there are several other accepted methods of reducing belt drive noise: Split Width Timing Belts. Although this method generally results in only very small reductions, approximately 4-5 dB, tests have shown it will help.

Can a timing belt change cause exhaust valves to burn?
That is absolutely ludicrous and even if the intake valves are not bent due to a mistake it’s also possible that the exhaust valves could burn depending on the cam timing situation. You cannot continue to drive the car like this; period. I would approach them one time about making this right.
What are the symptoms of a timing belt going bad?
Let’s look at some of the symptoms of a bad or failing timing belt: 1. Engine runs poorly: A worn timing belt can slip, getting out of the proper alignment. 3. Ticking sound coming from engine: A failing timing belt can cause a ticking noise when the car is running.
What sound does a timing belt make?
The big sign that a timing belt is about to jump or break is clanking sounds. These sounds can be metal sounding or like a jingle sound. It will kind of sound like you is shaking your keys or a metal chain. These sounds occur because the timing chain is getting loose and hitting things as it spins.
What is your timing belt noise telling you?
When the timing belt starts to wear out, it may create a ticking sound inside the motor. This warning sign may also be an indication of low oil pressure or the engine not having the proper amount of lubrication.
What does a bad timing chain sound like?
Place the probe of the stethoscope on the top or side of the timing chain cover. If you hear a rattling or scraping sound, with no other noise being emitted from the engine, it indicates a bad timing chain.
How can you tell if a car belt is a chirp or a squeal?
One method to determine if the noise is a chirp or squeal is to use a water squirt bottle and spray the rib side of the belt while the vehicle is running. If the noise gets louder, it’s a squeal. If the noise goes away, it’s a chirp.
What causes belt noise and what causes misalignment?
One of the biggest burdens today for professional technicians and do-it-yourselfers is belt noise, and the No. 1 cause of belt noise is misalignment. There are two distinctively different types of belt noise, “Chirp” and “Squeal”. Each has its own unique characteristics, causes and solutions.
What causes a high pitched squeal when you change a belt?
A new belt is recommended once the accessory drive has been realigned. “Squeal” is a high pitched noise, typically lasting several seconds in duration. This type of noise will typically increase in volume as the engine speed increases, and is caused by relative slip between the belt and pulleys.
