Replace drive belts at 30k miles?

jchammond · 06-06-2017, 04:35 AM

Did mine @65,000 12/15'... no crack's & 4yrs. old from build date.
I drew a diagram on bottom side of radiator (because of the routing) and replaced it.
Not bad from bottom side & put the old one in the sleeve for a spare.
#1 thing that i did notice & it was the same on all of them,,,the idler pulley's seemed to have a bit more clearance than i'm use to seeing.
It could be designed that way, because of the high rpm's of engine...but bearings were all smooth-they just seemed to have extra play in them.
82,000+ and running great.

Destroyed my serpentine belt at 57k. Shredded it at the race track and replaced the belt. Fast forward 14k miles later, I sold that car bought a 6spd manual with 42k miles, put two track days on it and it's now at around 52k miles. Changed the belt last weekend just in case and the job wasn't too hard.

Mine blew out a just over 20k, I took it to the Nissan dealer in Montclair and they changed it and the idler pully under warranty.

I usually go with OEM belts and hoses...there are probably some crap ones out there from "overseas"

97K miles here and the belt looks fine

Not only mileage, but I think it is also based on years every 2 to 3 years regardless of the miles driving. I have a 2013 Nismo, I purchased 9 months ago with only 13k miles on it...I changed the belt stick with OEM ...easy as hell honestly.
