The 2008 Acura RDX originally had a 2.3 L 4-cylinder engine with a timing chain system, a feature shared by models made from 2007 to 2012. However, starting in 2013, the RDX started using a timing belt instead. Typically, the timing chain should last the entire lifespan of your vehicle, but it could fail in cases of severe engine damage or after an accident. If you need to replace the timing chain, expect to pay around $150 to $250 for a timing chain kit. Due to the complexity of the task, it's advisable to have a mechanic handle the job, which may cost anywhere from $700 to $1100 for both parts and labor.
