Ive got a road trip coming up and my 2004 V8 now has 176K miles, last timing belt change was at 89K miles. Everything is up to snuff, and im confident with the rest of the SUV. Would you be worried to take it on an 800 mile total road trip?
I try not to do any major service right before a major trip unless I have time to shake it down… I rather drive on something that has been working just fine.
Change it after, some people go way over the 90k life and there belt looks good.
I just did a full timing belt change at 130K. Bought my 2003 used last year and there was no evidence if it was changed before (sticker with date/miles). The belt looked great except for the threads coming out at the 2 locations where they are visible on a new one, so if it was original it held up great.
