How many miles should I change timing chain on Honda Accord?

According to the Honda Accord owner's manual, the timing chain should be replaced every 105,000 miles or 7 years, whichever comes first. However, some mechanics recommend changing the timing chain more frequently, especially if you drive in harsh conditions or put a lot of miles on your car. If you are unsure when your timing chain needs to be replaced, you can take your car to a Honda dealership or a qualified mechanic for an inspection.
