Timing Belt vs Drive Belt: Are These Both Same?

“What’s the difference between timing belt vs drive belt?” is a popular question among those wondering about the two types of belts that come with most modern vehicles — the drive belt and the timing belt. Both belts are vital for the vehicle’s proper functioning.

Timing Belt vs Drive Belt

Even though they have a similar makeup, they are different in terms of functionality, material, and location. Let’s find out more about the differences between drive belt and timing belt here!

Features Drive Belt Timing Belt
Complexity of repair Easy to replace Requires timing setting and some disassembly
Cost Less expensive More expensive
Location in engine Front Timing cover
Function Powering important engine accessories Ensures synchronization of camshaft, valves, and crankshaft.

What Are the Differences Between Drive Belt and Timing Belt?

The main difference between drive belt and timing belt is that the drive belt is located on the exterior part of the engine, and they provide power to some engine components. Timing belts are placed inside the engine, and they help to synchronize the camshaft and crankshaft.

Both products are reliable, and you can choose either one based on the requirements of your vehicle. They also have other differences, and it’s important to know these differences before choosing. These differences include the following:

– Main Functions

The drive belt receives mechanical power from the engine and delivers it to different peripheral devices for a vehicle to run smoothly. People also call these belts serpentine belt because it takes the appearance of a snake. The belt basically coils itself to different accessories to provide drive and power. If the serpentine belt fails, it can cause other peripheral devices to fail equally.

On the other hand, the prominent purpose of the timing belt is to synchronize the crankshaft and camshaft. This belt is designed to enhance the movement of these components in cases where the gear does not function properly. Another thing to note is that the timing belt allows the camshaft to shut and open the intake and exhaust valves.

– Make and Appearance

The appearance of the two belts is also an area of confusion and a reason why most people use the terms interchangeably. Even though they are both long belts used in vehicles, there are some differences and similarities in their appearance. For example, both the serpentine belt and timing belts are made of rubber.

However, the rubber used for the timing belts utilizes high-tensile fibers or fiberglass for extra tension. Another thing to note is that the timing belt features high-quality materials like welded urethane, molded polyurethane, and neoprene. On the other hand, drive belts either include flat and fabric leather, in addition to rubber.

Another distinguishing feature in the appearance is that the drive belt has fewer teeth than the timing belt. This is because timing belts are mostly applied for the synchronization of crankshaft and camshaft, and as such, it needs zero slippage and better grit. On the other hand, a drive belt is applied for the continuous flow of power, which is why it doesn’t have many teeth.

– Cost and Service Life

Drive belts are generally cheaper because they are located inside the engine, while timing belts are more expensive. It’s not easy to reach the timing belt, and repairs require more labor, unlike with drive belts. This also applies to the replacement cost, with timing belt replacement being more expensive than drive belts.

They also differ in there service life. In general, drive belts require replacement after every 30,000 to 50,000 miles. On the other hand, timing belts require replacement after every 60,000 to 100,000 miles.

– Effects of Failure

If the drive belt breaks when the vehicle is running, the effects will only affect the accessories it supplies power to. This can result in overheating and eventually lead to the failure of your engine. On the other hand, if your timing belt breaks, it can significantly affect your engine, and you may need to get a full engine replacement.

What Are the Drive Belt’s Characteristics and Specifications?

The drive belt’s characteristics and specifications include providing power to different parts of the vehicle. This includes the water pump, alternator, air conditioning, and fan for some vehicle models. The belts are located on the exterior part of the engine and are made of rubber.

Element and Properties of Drive Belt

One of the two types of belts that most modern cars use is the drive belt, and it’s designed to perform different functions, all of which are vital for the car. Drive belts are also known as serpentine belts, and it’s a single belt that is driven by many pullers. This drive action allows it to provide power to components like the crankshaft of the engine.

As mentioned earlier, the serpentine belt helps to provide power to some of the most essential parts of the car, and this also includes the power steering systems. Today, most car engines are designed to utilize the serpentine belt as a source of power for the engine fan.

According to most manufacturer reports, driving belts can last between 30,000 to 50,000 miles, but this depends on the driving conditions. It’s important to know how to identify faults within the drive belt, and you don’t need a mechanic to do this. Signs to look out for include squeaky, loud, and other unpleasant noises from the engine bay. There are also cases where the issue can result in loss of air-conditioning, loss of electrical power, or overheating.

Other symptoms of a faulty driving belt system include cracking, melting or malformation, rip separation, abrasions, and uneven damage on the ribs or belt. The cost of replacing the drive bet also varies, depending on the seller.

What Are the Timing Belt’s Characteristics and Specifications?

The timing belt’s characteristics and specifications include directing the movement of the camshaft and crankshaft to ensure that the introduction of file, spark, and exhaust gas flow happens concurrently. This is a long rubber belt that connects the camshaft with the crankshaft to align their rotation.

Aspects and Hallmarks of Timing Belt

One of the key features of the timing belt is the hard teeth that interlocks the cogs of the crankshaft and camshaft. Timing belts are located within the interior compartment of the engine, unlike driving belts that are on the exterior part.

These belts are very important for combustion engines. This is because it’s vital for the spark and flow of exhaust to occur at the right time. The timing belt plays a key role in ensuring synchronization in the movement of the crankshaft and camshaft.

Timing belts are also designed to last long and only require changes after every 60,000 to 100,000 miles. This implies that you can use them for as long as 10 years with correct maintenance. A faulty timing belt can cause the engine to find it difficult to run smoothly. There are a lot of signs and symptoms to look out for to help you determine whether or not there’s a fault in your timing belt.

Some symptoms to look out for include loss of oil pressure, rough idling, and misfiring. There are also cases where a faulty timing belt will cause the pistons or valves to break. In addition, symptoms like engine failure, ticking noise from the engine, and oil leaks from the rear are also signs to look out for.

The cost of replacing the timing belt varies depending on where you do the replacement, the brand, and the model of the timing belt you get. In general, timing belt replacement generally costs more than drive belt replacement.

Is a Timing Belt and a Drive Belt the Same Thing?

A timing belt and a drive belt are not the same thing. While the former is crucial for synchronizing engine camshaft and crankshaft rotation, the latter helps power various components like the alternator or water pump. However, neither of them relate to fixing a stuck seatbelt.


The two belts are important for the car’s engine, and your car won’t start if any of the belts malfunctions. Forcing a vehicle to run with a damaged timing belt can cause internal parts within the engine to damage, and this can be hard to fix in many cases. Both components are vital and require regular maintenance to ensure that vehicle components like valves and pistons function properly.

Drive belt is a vital component that ensures that different car components are operating up to the required standards. It also requires proper maintenance, as a malfunction could cause your vehicle to overheat. These issues can also cause the air conditioning and batteries to fail. A key thing to note is that the dangers associated with a faulty timing belt are always more than that of a drive belt.
