Does the Chevy Sonic 2013 have a timing belt or chain?

The 2013 Chevy Sonic 1.4 liter turbo is equipped with a timing chain. The 1.8 liter engine employs a belt. The 1.8 l's belt needs replacing at 97,000 miles, but the Sonic's timing chain is designed to last the lifetime of the vehicle. By default, metal chains are more durable, don't suffer from cracking or drying out like belts do, and can improve fuel economy. Chains are also more protected, operating from inside rather than outside the engine. Occasionally they break, which can have catastrophic results for the engine. If You're finding metal shavings in the oil, experiencing mIS Fires or hearing a rattling noise while idling, have the chain examined by a mechanic. Cost to replace a timing belt on the Sonic averages $500-$600 in parts and labor.
