How does the timing chain work on an engine?

Every time you use the engine, the timing chain will be used. It connects the crankshaft to the camshaft. The metal links in the chain move on the tooth sprockets on the end of the crankshaft and crankshaft so that they rotate together.

Can a check engine light be a bad timing chain?

The check engine light can illuminate for a variety of reasons, one of which could be a failing timing chain. A car’s computer will display warning lights that must be checked and scanned for trouble codes to determine the source of the issue.

What are the bright links on a timing chain?

Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.

What should I do to tighten my timing chain?

Tighten the chain according to your car manual’s specifications. Some chains are tensioned by adjusting either the crankshaft gear or the camshaft gear, while others have an automatic tensioner. This will vary by make and model of your car. The important thing is to make sure that your timing belt is as tight as it should be.

How often should the timing chain be replaced?

The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem. Issues with the chain are pretty common in high mileage vehicles, so if you are driving an older vehicle, or one with a lot of miles, it is best to be on the lookout for symptoms of the timing chain going bad or failing.

How does the timing chain work in an engine?

The timing chain or timing belt (sometimes called a cambelt) is an essential part of every internal combustion engine. Sometimes the job is done by a system of gears instead but there has to be some method of synchronizing the crankshaft rotation with the camshaft(s). This makes the valves of the engine open and close at the right time.

How can I tell if my timing chain is bad?
