Does the 2009 Infiniti G37 use a timing belt or a timing chain?

The 2009 INFINITI G37 comes equipped with a timing chain, which is housed inside the engine and gets lubricated by engine oil. Unlike timing belts that are located outside the engine and are prone to drying out and cracking, timing chains can last a long time. To prevent timing chain problems, it is essential to maintain your engine properly and have the engine oil changed according to the manufacturer's recommendations. Using high-quality engine oils and oil filters can also be beneficial. It is crucial to keep the oil level correct to ensure continuous lubrication of the timing chain, especially since many modern engines are known to consume oil. Timing chains typically last the entire lifetime of the engine. However, when the mileage gets high, around 200,000 miles or more, a timing chain may potentially cause some timing issues and require replacement at that point.
