The timing chain on a 2010 Scion xB typically does not require regular replacement like a timing belt, as it is designed to last the lifetime of the engine. However, if you experience symptoms like rattling noises from the engine or poor performance, it may indicate that the timing chain or its tensioner needs inspection or replacement. If you suspect issues, it’s best to consult a mechanic for a thorough diagnosis and potential replacement, which usually occurs around 100,000 to 150,000 miles if necessary.
