How often should the Serpentine Belt be replaced?

 

It should be checked for cracks and if you have a belt gage you can use that as well. They rarely fail, but when they do it will be spectacular As a rule of thumb they should last around 60k. Sometimes they will start making noise when they get a glaze on them from the smooth side of the pulleys...doesn't mean they're bad, just a bit noisy.

 

Generally, most dealer replaced them around 105,000 miles.

Look for cracks and damage. Then check the position of the drive belt auto-tensioner indicator. The indicator is located on the auto-tensioner, see attached pic. Replace if it is not within the range shown.

If there are a lot of cracks or damage, then you may want to replace sooner. Most drive belts will develop a few minor cracks with wear and still be okay.

 

7 years, or 105k miles, whichever comes first. They will usually start slipping, on damp mornings, way before they snap.

 

Thanks!
Where can I find this information for all the other replacement intervals?

 

It is not listed. The 7 years/105k belt change, which ever comes first, is based on previous generation Accord service recommendation. The dealer generally goes by the condition of the belt, the tensioner range, or the 7 year/105k interval.

Your car has the maintenance minder, which will show service codes at different intervals. With the exception of motor oil, most other maintenance minder service codes are based on mileage, etc.

 

I personally wouldn't let a belt go 105k, but that's just me and my opinion.

 

I will be honest with you. On my own car, I wouldn't let it go to 105k. I changed my drive belt around 77k on my 2009, it was still fine; but, I like to keep things fresh. Even on my dad's Toyota, I always change the belts early.

 

To add, my friend knows, the belt on the wife's Pilot was replaced at ~83k.....and those hyd belt tensioners vs the spring loaded ones are a different animal ...the slow balde wins......
