This allows for the precision movement in the valves and pistons of your vehicle so that your engine fires at the exact precise time. They synchronize the motion of the crankshaft and the camshaft. Whether your vehicle uses a timing chain, or a timing belt purpose is the same. One of the most common problems with a timing belt is that the rubber teeth on it can fall off and get stuck in the gears, potentially causing a catastrophic failure for your entire engine. The result is that you'll need to have them repaired more often. Unfortunately, because they are rubber, they tend to fall apart more frequently than timing chains do. Chains are making a comeback in some newer automobiles, but many still make use of timing belts because they do reduce cost. Timing chains are generally stronger than timing belts, as you would guess, and they last longer as well. It was part of a cost-cutting measure through the production of vehicles as a reason oil prices and other concerns that made manufacturers want to reduce the cost of making vehicles overall.

Older cars used to exclusively have timing chains, but during the 1970s belts became the norm.

Timing chains are made of metal, while timing belts are rubber. These terms are often used interchangeably but they're not exactly the same thing.

Your vehicle has either a timing belt or a timing chain inside of it.
