In contrast, timing chains are much stronger and more durable than timing belts. Timing chains typically last the life of the engine. The main disadvantage of timing chains is that they cost more to manufacture.

But first, you need a replacement timing belt or chain. Quality matters a lot. OEM timing belts and chains are generally better than aftermarket ones. It's because they are designed to be the exact same size and type as the original equipment. Aftermarket timing belts generally cost less because they have a universal design. Like with many car parts, you get what you pay for. Aftermarket timing belts and chains rarely last as long as OEM ones.

You can find the timing belt outside of the engine. The timing chain is on the inside, where it’s lubricated by the engine oil.

Each design its own advantages and disadvantages. Many older Toyota models have timing belts. All newer Toyota models have timing chains. Toyota did away with timing belts for several good reasons.

It's pretty easy to replace the timing belt by yourself. There are plenty of model-specific tutorials available on the web. For example, here's a timing belt replacement tutorial for the Toyota Highlander.

Whether an engine has a timing belt or a chain, the setup is the same. The belt or chain's rotation determines the engine's timing.

Timing belts and chains are designed differently, but they function the same way. The crankshaft powers the timing belt or chain. There's a pulley or gear at the front of the engine, mounted to the crankshaft.

From the crankshaft, the belt or chain extends upwards to the camshaft pulley(s) or gear(s). There's one pulley/gear if it is a single overhead, inline camshaft configuration. There's more than one pulley/gear if it is a V-style or multiple overhead camshaft configuration. Between the crank and camshafts, the belt or chain often powers other critical engine components. For example, the oil and/or fuel pump, depending on engine configuration. Often, the tightness of the chain or belt is regulated by a tensioner pulley as well. It's a small pulley that pushes or pulls on the chain/belt to provide the tension.

The timing belt (also called a cam belt) or timing chain play a big part in your engine's valve timing. A timing belt or timing chain is what synchronizes all the engine's operations. It creates the timing intervals the engine runs from. Most modern gasoline and diesel-powered engines use a timing belt or a timing chain to accomplish this.

The timing belt or chain links the rotation of the crankshaft to the rotation of the camshaft(s). This, in turn, dictates when the valves open and close. The valves control the flow of fuel or exhaust into or out of the combustion chambers (cylinders). It is critical that the crankshaft and camshaft(s) be in perfect time for the engine to run at optimum.

OEM timing belts and chains tend to be more expensive than aftermarket ones, but not always. You can find pretty great deals online. For instance, we carry genuine OEM Toyota parts, including timing belts and chains, at deeply discounted parts. Check out our inventory of OEM Toyota timing belts and chains here!

Timing belts have a few disadvantages that timing chains do not. First, timing belts experience stretching over time and will wear out after 90,000 miles or so. Replacing a timing belt is not difficult for a mechanic, but it is time consuming. A car owner will typically pay more than $1000 to have the timing belt replaced.
