The timing chain in a Toyota V6 engine typically needs to be replaced every 90,000 miles or 72 months, whichever comes first. However, this interval may vary depending on the specific model and year of the vehicle. It's important to check the owner's manual or maintenance schedule for your vehicle to determine the recommended timing chain replacement interval.
Replacing the timing chain is a complex and time-consuming process, so it's best to have it done by a qualified mechanic. The cost of a timing chain replacement can vary depending on the shop and the vehicle model, but it typically costs between $500 and $1,000.
Ignoring a worn or damaged timing chain can lead to serious engine problems, so it's important to have it replaced according to the recommended schedule.
