When I supposed to change timing belt in my Acura TL 2004, 6 spd.

 

i think at 105,000 miles. i was told this and im not totally sure but rule of thumb is you change a timing belt every 100,000

 

Most do it at 105

 

The most correct answer is:

"When the MID tells you to."

When the MID shows a service minder with a "4", then it's time to change the belt. There is no mileage associated with a timing belt change in the Owner's or Service Manuals, but most folks have got the message around 105K miles. (Note: the owner's manual does list 60K for severe driving conditions.)

See page 199 of your owner's manual.

 

There's usually a time limit too. I think it's something like 105Kmi or 7 years, whichever comes first.

 

This discussion of time/miles has come up before, but I have yet to find any Acura reference to either (except for the 60K for high/low temp operations listed in the 3G owner's manual, pg 199). It's also possible that the MID is set to display a "4" after a set time if that "set time" arrives before the mileage trigger.

One might surmise that Acura arrived at the 60K figure by simply cutting their regular interval in half (i.e 120K).

I'd love to see any written Acura reference to time/miles for timing belt replacement.
