    I bought a 2004 with 111,000 miles on it and getting ready for a 2,000 mile trip. There’s no record / maint history of a timing belt change. I pull one of the covers and the belt looked very good. I noticed the belt said “made in USA” . Can I assume that the timing belt has been replaced based on this info?

    thanks in advance.

    Welcome from NY.

    I would change the belt before the trip. It added insurance. Pay me now or pay me later. It's cheaper to fix before it breaks.

    I hear you and that was my thought, but after disassembling a bit and pulling the covers... the thermostat was relatively new, all bolts and fasteners removed with ease, and the belt is in great shape for 16 years and 111,000 miles.
    Just trying to confirm if Tundra 4.7s were originally assembled with “made in USA” timing belts?? I don’t think so. And the condition of the belt, new thermo, and easy bolts leads me to believe it was done around 90k.
    I don’t mind doing maintenance just don’t have the time or money for unneeded maintenance.

    I would start by checking the timing belt cover for markings. Usually the mechanic will write the date/mileage on the cover. the belt can look pretty dang new after 100k miles. Mine did...


    if there aren’t any markings Then it comes down to whether or not you have 8-ish hours to do it or $1k bucks to spend on it before your trip.
