What are Car Belts? Different types and their importance

Car belts are an essential part of your vehicle as they ensure that the various components of the engine work seamlessly. Without belts, your car might break down and face major mechanical issues, leading to costly repairs. Understanding the types of belts and their roles in keeping your vehicle functioning smoothly can help you maintain your car's performance.

Types of Belts in a Car: Accessory, Timing, and More

There are several important belts within a car engine, all serving a specific purpose. These include:

Accessory Belt: This is a single, continuous belt that controls multiple parts of the engine, such as the alternator and air conditioning compressor. Thanks to the accessory belt, multiple systems can be driven at once.

Timing Belt (sometimes referred to as a cam belt): The timing belt synchronizes the movement of the engine’s camshaft and crankshaft, ensuring proper timing of the engine's valves and pistons. A broken timing belt can lead to severe engine damage.

Drive Belts: These types of belts are often found in older vehicles and are individual belts for each system, such as the water pump or alternator. Nowadays, they have been replaced by the accessory belt.

What is an Accessory Belt and How Does it Work? 

An accessory belt is essential for transferring power to critical vehicle components. Thanks to the smooth operation of this belt, all these components run efficiently and in sync.

When the engine is running, the accessory belt moves continuously, ensuring that each of these systems operates effectively. Without a properly functioning accessory belt, you may experience battery issues or overheating. That's why regular inspections, at service centres such as Motrio, are essential to avoid sudden breakdowns.

Common Signs Your Belt Needs Replacement

Over time, belts naturally wear down and need to be replaced. Luckily, there are many signs to watch out for before it’s too late.

One of the most noticeable is hearing strange noises, particularly a squealing noise when you start the car or turn on the air conditioning. A high-pitched sound could mean that the belt is slipping or worn out and struggling to do its job properly.

Belts, especially those made of rubber, tend to degrade over time, particularly if exposed to high heat. If you spot any cracks or frayed edges, it’s a good idea to get the belt replaced.

For the timing belt, signs that it needs replacement include a squealing or a ticking noise coming from the engine. 

Finally, the most obvious signs to look out for are the loss of power to a certain system and your dashboard warning lights.
