Timing Belt vs. Timing Chain: What’s the Difference

Every component within your engine is perfectly synchronized. It’s truly amazing that motors can produce so much power and move so quickly with elite precision. Every stroke, every time. The flawless timing of your engine is the responsibility of, unsurprisingly, your timing chain. belt.

Both timing belts and timing chains carry out the job of ensuring your valves and cylinders are in perfect harmony every time you start your car. Without it, your engine wouldn’t survive. Valves would crash into each other, mistimed air intake or exhaust, pistons extending at the wrong time; all of these can and will lead to catastrophic engine failure.

Timing Belt vs. Timing Chain

Now that we’ve made the similarities between the two clear, it’s time to look at what sets these two components apart despite carrying out the exact same duties. Chains and belts are made of completely different materials.

Timing belts are made of a thick rubber material, allowing for quiet operation and cheap production. Timing chains, on the other hand, are well, chains. They’re made of durable metal and are usually more expensive to produce.

However, material isn’t the only difference, though. Timing belts are located on the outside of the engine, exposed to the air and debris around them. This can cause them to dry out, stretch, or crack and cause issues down the line. Timing chains are instead located on the inside of the engine and constantly lubricated by the engine’s oil.

Which is better?

So far you’ve probably got the impression that timing chains are a superior option; they do come with downsides. Timing chains are typically considered much noisier than their rubber counterparts, which can make them appealing for manufacturers looking to make a silent luxury car. Belts are made of a soft material, which means that they’re usually the quieter of the two options.

However, many manufacturers are focusing on timing chains for their modern vehicles, as advances in quieter chains and cheaper production have made them the clear choice for many models.

Timing chains are also the more durable and long-lasting option. As stated earlier, what makes belts so appealing for their price and noise reduction also makes them the higher maintenance of the two.

Timing Failures

Both timing chains and belts have made advances in durability and will last much longer than their predecessors, but timing failure is still a real possibility and should be addressed immediately. It can be a product of a misaligned or improperly tensioned belt and cause major issues without repair.
