Does the 2014 Buick LaCrosse have a timing belt or chain?

The 2014 Buick LaCrosse has a timing chain that is used on the engine. This is an improvement over a timing belt because they can last longer. Changing a timing belt in an engine is usually one of the most expensive pieces of service that You have to do. Using a chain means that You will not have to change it. A belt usually lastS60,000 to 100,000 miles and a chain should last over 300,000 miles. I recommend You still check Your timing chain at least once a year to make sure that it is tight and free from damage.
