Hey guys, this is a atupid question, but I can't find anything in my owners manual. Most of the $15K in mods on my 03 Convertible where done professionally, I am not a gearhead. Do these cars have a timing belt/chain that needs to be serviced? I know most cars need it every 60,000 miles, but what about New Edge Mustangs, mine is a 2003. Thanks in advance, my friends.
