How are gears connected to the timing chain?

Locate marks on your crankshaft and camshaft gears. These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly.

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.

A timing chain doesn’t need to be replaced unless there is a problem with it.

Where is the timing chain located in an overhead cam engine?

In overhead cam (OHC) engines, the camshaft is located high in the cylinder head far from the crankshaft. This requires a much longer chain or a rubber belt to drive the camshaft. In some engines, such as a Chevy 3.4L DOHC V6, a timing chain is used to drive an intermediate sprocket that drives two belts (one for each cam).
