If you have a shop do it, make sure to ask for Napa/Gates belts so they don't just use some cheap POS.

I change mine every year but it's very hot here in Phoenix and my engine bay also has a lot more heat than the normal G's. Plus the way things have been the last few years I seem to have my motor out once a year anyway. LOL

Belts are ultra easy unless you have the mechanical fan! ugh

how hard is it to really do this yourself? is it a big head ache to buy the 2 belts yourself and try to do it? Can everything be done from the top. I have no stands to get under the bar from bottom. I dont want to mess anything up then too late because i already took other belts off.

If you have no stands, then i'd recommend not doing it yourself. stands are cheap, go get a pair

My belt broke while driving, I then replaced both serpentine belt & A/C belts, Car started and was able to drive for a bit, but now car won't start? Any idea what it could be.

did your alternator belt break also??

if so your battery may need to be charged or possibly replaced

useful thread. thanks for the info guys my car's @ 69K now and they recommended i change the belts. alternator belt was worse than the ac belt. called the local herb chambers infiniti dealership and its like $230 total. Getting it done @ valvoline this afternoon for about $120 but an extra 15% off since im a teacher, so it'll be about $100 even.

^ In this case it truly depends on what your time is worth. Is 70 dollars worth an 1 hr of your time.....Food for thought for the next person thinking of doing this work.

I keep getting told that there's only one belt for both AC and power steering. Is it because I have a coupe? Firestone told me its two belts while everyone else said its just one.

I need to have mine changed now that I'm at 45k miles. Sears is charging $75, Pep Boys $106, Firestone is $130. They all use Dayco although Firestone might use Gates.

why don't you just look under the hood?

It's really fairly simple. I used an online video in YouTube and one from Infinitihelp. Followed it step by step and wallaaaah, 1 hour later it was done. It took me longer b/c I don't have the strength needed to maneuver as easily as you guys. It saved me $70+; however, I make very, very good money so that's not an issue.

My thinking is that if a completely non-mechanically minded muchacha can do this, most everyone else with:

*** all appendages attached,
*** >2 firing neurons,
*** who's breathing, and
*** has a pulse of 60-80BPM,

can also do it. I'd much rather learn just in case I'm ever stranded somewhere on some lonely rode in backwater Alabama or Nevada.

Chica you never fail to crack me up. Good stuff.

I bought my G35 used so I'll probably just go ahead and change the belts since I'm driving the G everyday through rush hour traffic...lol

^^^ These used to be my dating criteria (all appendages attached, breathing, a pulse, >2 firing nerve cells.... and able to more than grunt or scratch himself), but had to up the standards a bit since it was attracting the wrong kind of men:

Ciao and have a fantastic day,

Haha thanks for the tip on looking under the hood I wonder what lies in there.
