The operation of an automobile is accompanied by a combination of intricate sounds. However, not every sound symbolises functioning, some of it is caused due to a malfunctioning part. One such noise is of timing belt. The timing belt harmonises camshaft and crankshaft rotation in the engine. That said, a noisy timing belt is an indication of an underlying issue with an auto part. The timely identification and fixture of timing belt noise can secure car owners from major problems like engine failure.
Here we have elaborated on the core reasons for timing belt noise and how to fix this noise.
What is Timing Belt Sound?
Before discussing what the timing belt sounds like, let’s first quickly glance over what this belt is all about.
A timing belt is a crucial component of the internal combustion engine. What basically a timing belt does is connect the camshaft to the crankshaft in your engine, enabling a synchronized rotation that allows the engine to properly function. Therefore, if the rubber belt breaks, the functioning of an engine can be affected significantly.
As for the timing belt noise, if the belt does not work properly, there is synchronization. This is when your car starts to make unusual sounds, called bad timing belt noise.
Timing Belt Sounds
The following symptoms will help identify if the noise coming from your car is a timing belt noise or not.
Ticking Sounds
The teeth of the timing belt make it sound different from the other moving parts of the engine, such as a serpentine belt. The meshing teeth on the inside of the timing belt running between the camshaft gear and the crankshaft gear keep the gears in place. When the teeth wear out or fall off, fast-paced, repetitive timing belt noise is generated as it rotates.
Squealing Sounds
Although squealing noises are mostly associated with the serpentine belt, an irregular squeal can be due to a worn-out timing belt. Unlike the ticking timing belt sound, this sound is not continuous. However, when you hit the brakes or accelerator with full force, the timing belt makes squealing sounds.
The best way to be sure the symptom is related to a problem with the timing belt and not any other belt or part of the engine malfunctioning – is to visit a mechanic who would open the engine and visually inspect your vehicle engine’s timing belt.

Knocking Sounds
If the timing belt tensioner is loose and the timing belt is getting stretched out because of this reason, you will continuously hear knocking or slapping noises. This happens because the loose timing belt hits several parts inside the timing belt cover.
Other Symptoms of a Malfunctioning Timing Belt
Aside from the noise, here are some other symptoms indicating a failing timing belt.
Flickering Engine Light
If there is a problem with your timing belt, your engine might flicker the check engine light on your dashboard. However, there are several reasons why the check engine light goes on. So just to be sure, check your car manually and with the help of devices. For manual checking, start your car, if your car cranks but won’t start, it is due to a timing belt.
Aside from manual checking, use an onboard diagnostic tool or plug an OBD2 scanner into your car to figure out why the dashboard light turned on in the first place.
Motor Oil Leaks from the Engine
Other than timing belt noise, another sign identifying your timing belt has gone bad is motor oil leaking from the front of the engine. Generally, oil leakage starts from the timing belt cover. Another reason for oil leakage is when the gasket fit between the engine block and timing cover debilitates; it will also happen if the gasket has a crack or has been improperly installed.
Smoke from Exhaust
Smoke from car exhaust can indicate several malfunctionings, including a failing timing belt. When a timing belt malfunctions, it disrupts the rotation of shafts, forcing the engine to work harder. The additional force incurred on engine components causes different damages, like oil leakage, which leads to excessive exhaust smoke.
Engine Misfiring
The core role of the timing belt is to maintain the synchronisation between moving parts of the engine. That said, any sort of disruption will cause cylinders to work at different times, causing engine misfiring.
The above-mentioned systems can be avoided by changing a timing belt on time. Here is when to change a car timing belt to avoid any hassle while driving.
What to Do When Timing Belt Makes Noise
In order to isolate the noise, you should go through the following process:
- Park your car and turn off the engine
- Open the hood and remove the serpentine belt
- Start the engine again and see if there is a noise
- If there is noise, this is most definitely a timing belt sound, making it clear that the timing bad is wearing out
- Get the timing belt replaced by a professional
Timing belts are easily available throughout the country. You can buy a number of car parts and accessories in the UAE online. However, replacing it requires a lot of expertise. Therefore, it is suggested to seek professional assistance from a mechanic to replace the timing belt.
FAQs
How do I know if my car timing belt is bad?
The easiest way to rule out a failing timing belt is by noise. When a timing belt malfunctions, the car creates different types of noises indicating an underlying issue.
Can a timing belt affect acceleration?
Yes, a malfunctioning timing belt can affect the overall engine performance, making it difficult to accelerate and shift gears.
How long does a timing belt work?
It varies from manufacturer to manufacturer and usage of the vehicle; however, a right-hand thumb rule of timing belt life span is almost 96,000 km.
That is all about timing belt noises and solutions to the problem. Besides, if your car asks for lots of repairs and you face mechanical issues often, it may be because your car is ageing. In such a situation, it is a good idea to buy another car and avoid hefty repair and maintenance expenses. Take a look at used cars in the UAE here.
