Hello I have a 2007 honda civic ex and I am pretty sure that I have a belt and not a chain. I do not have a drivers manual because I bought this car as a used car. I have 64,000 miles right now and was wondering when I should replace my belt. Thank you for your help.

 

If you have a belt you should replace it. However, I believe the 2007 Civic has a chain.
The maintenance interval is 110,000 miles, so that would indicate chain.
