![]() One of the greatest signs of a bad timing chain is a rattling sound when your engine is idle. Still, if you don’t have the luck of your timing chain operating throughout the life cycle of your vehicle, we’ll deal with the signs of bad chains. ![]() On the other hand, timing chains last much longer if properly maintained. Timing belts should be replaced every 5 or 6 years, or within 60,000 to 100,000 miles. One benefit of driving a car with a timing chain is that the engine is quieter when compared to those with timing belts. However, that’s not always the case, since the chain could get damaged as well. ![]() Well, some manufacturers certainly claim that their chains should truly last forever, for as long as you change the engine oil frequently. These are all the downsides of timing belts, so one would think that timing chains could last forever. So, you won’t have to worry about your belt freezing in cold weather, or wearing off due to high engine temperatures over time. On top of that, the timing belt is rubbery, while the chain is, you’ve guessed it, a metal chain. Timing belts are mostly used on cars with low engine displacement and older models, while more powerful engines usually have timing chains. The difference between timing belts and timing chainsĪlthough both parts serve the same role within your engine, timing chains are much more durable than timing belts. However, sometimes damages could occur, and it’s important to act swiftly in that case. Most modern cars have timing chains, which evolved from timing belts that serve the same purpose but are more vulnerable to heat.Ī timing chain gets lubricated by the engine oil which prevents wear and tear due to contact with the gears within the engine. If the timing chain brakes, pistons will hit the valves and damage the engine which causes expensive engine rebuilds. So, it’s one of the key components in your car’s mechanical system. It ensures that the engine’s pistons don’t hit the valves which would cause your engine to stall. It connects the crankshaft and camshaft, therefore opening the valves and controlling the pistons in a precise manner.īecause of the is chain, everything runs smoothly within an engine’s firing cycle. Your car’s timing chain is a metal chain mounted in the engine which rotates between the gears in the engine to move some of the crucial mechanical components. What’s a timing chain and what does it do? It’s always useful to know how a damaged timing chain will affect your engine’s functionality, so our team decided to give you a detailed overview of the greatest signs. So, it’s crucial to respond after hearing the first timing chain symptoms telling you it’s time to change your chain. The metal chain serves a key role in opening your engine’s valves on time, and its dynamic role in the engine makes it vulnerable. Technological advancements in the automotive industry enabled car manufacturers to replace rubbery timing belts with more sophisticated timing chains.
