The dealer said I should replace my timing belt. I have 122,000 miles. on 2004 Honda Pilot

Someone told me that it makes a difference if the belt or chain is metal or not. What is the advice on replacement please?

you have a timing belt and it should be repl every 100k miles,repl water pump and tensioners at the same time to save money in the long run
