timing belt
 

I have been giving three different mile figures of when to replace the timing belt on my Acura 2013 TL
1. 60k mechanic
2. 90k google
3. and dealer told me 105k

What is the right amount?

The dealer is correct.

I'm in the process of buying a 2012 TL Advance right now and it has 95k miles on it. Since the Acura dealer is collocated with the Honda dealer I walked into the Honda dealers service department, Acura shares this department with Honda. I asked the service rep that exact question and I was told 8 years or 100k miles whichever comes first.
