The 2016 kia optima is equipped with a timing chain. the pro side of this is that unlike a belt that needs routine replacement, a chain is designed to last the life of the vehicle. on the downside, if you do have to replace one, which happens sometimes, it's quite expensive. this part is constantly rotating when the engine is running. it essentially controls the intake and exhaust valves by sync-hronizing the camshaft and crankshaft sprockets. these valves need to open and close every time the engine fires. if a chain gets loose, it can throw the timing off. if it breaks, it can result in expensive damage. the most common symptom of a failing one is rattling in the engine compartment. friction can cause small pieces to break off. they land in the oil drain pan and bounce around while the vehicle is in motion. the average cost to replace a timing chain in a 2016 optima is $ 570 to $ 700. labor makes up the majority of that expense.
The 2016 kia optima has a timing chain. though a timing chain is more durable, they can get worn and stretch. if you hear a ticking noise in your engine, you should consider a service call to check the timing chain.
