It is important to note that noise could be indicative of a bigger issue that could cause damage to your belt, pulley or drive over time. If you need assistance in determining the cause and solution for our belt noise, please contact a BRECO flex applications engineer. February 27, in Blog , Knowledge Base.

The job of the timing belt is to keep the camshaft and crankshaft pulley in sync. This way, the valves and piston push at the correct time. So, what could cause noise in a timing belt? The timing belt is a part that is very important to replace before it is too late. Depending on the issue, the noise of your belt could vary. That high number is definitely on the rarer side of things and tends to be for high-end vehicles, but it's not outside the realm of possibility. One other thing to be aware of is that if your timing belt isn't that old, which is to say it has been replaced within the last 60, miles , then you may have another problem that you need to look at.
Most timing belts need to be replaced between 60, miles and , miles. Your best bet is to check your owner's manual to find out for sure. But if your belt has been replaced more recently than that and it should still be working, then you may have a problem with your timing tensioner rather than the belt itself. As the name suggests, the timing tensioner is what helps keep your timing belt tightly wound around those pulleys that it rotates between.
When the timing tensioner goes bad, the sound is often the squeal that we mentioned earlier or sometimes even a rattling sound. It'll be different from the ticking sound however, which is exclusively caused by those teeth wearing down that we mentioned.
A bad timing tensioner will mean that your timing belt is not able to maintain the precise timing that your engine requires and you'll get all the symptoms of a bad timing belt, even though your timing belt is still working properly.
Regardless of whether or not it's the tensioner or the belt itself, a mechanic is going to need to inspect the area and determine for sure which one it is that's failing and will need to be fixed. Aside from noises there are some other signs that you can be on the lookout for to let you know that you're having a problem with your timing belt.
If you're experiencing a noise as well as any of these symptoms, then there's a good chance you have a bad timing belt and you should get it checked out as soon as you can. Engine Misfires: As we've seen, your engine has to fire at a very precise time for everything to work properly.
If the timing gets misaligned then your spark won't be happening exactly when it needs to, and you're going to get a misfire in one or more cylinders. This will likely happen fairly frequently until such time as you get the timing belt fixed. Engine misfires can cause a significant reduction in overall power from your engine and reduce the performance accordingly.
Rough Idling : If you're experiencing rough idling and your vehicle seems to struggle and stutter even when you're just sitting still and not putting any stress on the engine, that could be an indication of a timing belt issue as well. As the belt slips away from the gears, the teeth could wear off and get stuck in the gears.
This will cause your engine to jolt and shake on you. Bad Oil Pressure: When your belt begins to wear down and pieces start to break off, if they don't get stuck in the gears causing the misfires and idling issues we mention, they can fall right down into your oil pan. When they clog up your oil pan is going to reduce your oil pressure overall, which can also cause your engine to overheat.
This will also lead to your engine overheating. A problem with your timing belt can cause the check engine ligh t to show up on the dashboard of your car. Unfortunately, there are literally hundreds of different reasons why a check engine light may come on so you may have to rely on these other symptoms to help narrow down the problem for you if the light does come on.
Even though the check engine light is a very vague warning that doesn't alert you to the specific nature of the problem that caused it to come on of the first place, it does at least let you know that there is a problem. That means you can combine it with these other observable side effects in the symptoms of a bad timing belt to help you figure out what's going on.
If you do have a check engine light on your dashboard and you want a more specific diagnosis of the problem before heading to a mechanic to get them to do your inspection your best option is to use the same diagnostic tool that a mechanic would use to check out why the check engine light showed up on your dashboard. You've likely seen the mechanic using what is called an OBD2 scanner before, or an onboard diagnostic tool.
It looks like a large cell phone or tablet and is usually in a bright yellow case, but not always. This is what a mechanic will plug into your car to test why a dashboard warning light came on.
Although the mechanic you go to probably has a very complex OBD2 scanner you can get a basic one on a site like Amazon. This will still be able to help you diagnose the problem so that when a check engine light comes on your dashboard you'll be able to know if it's the timing belt or something else under your hood that made it come on in the first place. It won't fix the problem, but it does tell you where the problem is, so you know what to do to get it fixed.
Unfortunately, the cost of replacing a timing belt in your car once it goes bad is a little overwhelming. This is one of the more expensive repair jobs that you're going to need to get done in your vehicle.
This is due to the fact that it's a fairly involved job to get to the timing belt which is located deep in your engine. Unfortunately, although it is technically possible to do this job on your own at home if you're not a very skilled mechanic already then you may want to leave this one to the professionals.
