- How to change the AC/alternator belt in your 4th gen Maxima.
As said, this applies to 5th ('00-'01), 5.5 ('02-'03), and 6th ('04-08) gens. Access to the main tensioner bolt is slightly more difficult on the VQ35 (2002-2008) due to the VTC covers, and possible more difficult on the 2004-2008 due to the subframe (vs crossmember of 1995-2003).
Make sure the belt is centered on all of the pulleys, otherwise it may seem tight but it really isn't. I forgot to mention this, and after I started it up to check, the belt was thrown into place and was extremely loose.
PS belt replacement: • 1995-2008 Nissan Maxim...
There are only 2 belts. The specs for both belts are in the FSM, in MA. Assuming new belts, the AC/alt belt should have 3.8-4.1 mm deflection between the compressor and crank pulley. PS belt should have 5.8-6.2 mm deflection on the bottom side.
@Ruef23 Could be faulty brand new parts, or more likely a wiring problem. Best thing to do is have the charging system tested. When you have concrete numbers on how it's performing, that can give a clue as to what's wrong.
@tank7500sw Just a 14mm wrench for the nut itself, then another wrench for more leverage.
@theejock What is this 'internal belt' pulley you're talking about?
Compare the pulley sizes between the old and new alternators. Some can be close enough in size to not be a noticeable difference at a glance, but enough so that the belt will no longer fit.
@plamster You could call it that if you'd like. I don't just because it doesn't drive all the accessories...personal preference, really.
A torque adapter or crowsfoot would be required, but I really wouldn't worry about torquing it to spec.
No, the water pump on the VQ is chain driven, a thrown belt should not affect your cooling system at all.
However, if you drove with no alternator for a while and your battery could not supply the current necessary to drive both cooling fans, it's possible you could see an overheat condition. I would think the engine would die first, but it's possible.
Well done. Thank you!
For a beginner like me, I will be using a torque wrench. How would one use a torque since there is no space for a socket torque wrench to tighten the pulley nut? Thanks.
I like your video
I hope you still look at this. The new belts are to big. I have tried two different belts and replace the tensioner. Still when I put the belt on and tighten it, slack slack slack.. What could be the problem..
Likely don't have the AC belt routed correctly. Wouldn't make a difference on the PS belt, though. What part number belts are you getting?
gtot a video on removing/installing the alternator
Thank you sooooooo much! Perfect!
Do u have Any instructions on how to replace the power steering belt?
Great video. Do you have a video on replacing the AC compressor? I believe mine is shot and could be the reason that my Alternator belt has disappeared...
Yes, I put the link in the description.
my belt completely popped off the battery light came on in the car, and the coolant in the radiator started to boil, is that also connected with the alternator belt some how?
What tool combination did you use when releasing the idler pulley nut.?
hello all. i still cant manage to put the damn belt on my alternator, the compressor, and between the tightener pulley and a pulley that is connected to an internal belt. Now i tried disconnecting all the parts one by one to see if the belt will give any slack, but it doesnt. i also tried to loosen the belt bolt, as mentioned in the video, and it doesnt really help. So basically i replaced the alternator and now i cant seem to put the belt back on.... Help please.
Not yet, but it's on the list.
Just to make it possible to film. Removing the wheel, or even jacking the car up just adds unneeded complexity to the job.
I change my alternator on my 2000 nissan maxima an replace my belt an wen on turn on my heater for windshield defogger it squeals any any ideas wat I did wrong ??? Would really help thanks
+Uriel Cruz Incorrect tension on the belt (defrost turns on the AC compressor, causing your squeal).
How can I put the right tension on the belt??
+Uriel Cruz There are belt deflection gauges and specs for that, but honestly it's just all about feel. You want maybe 1/2" deflection at the longest run between pulleys is a good rule of thumb.
how tight should all three belts be?
Yes, compressor video here - watch?v=UKulYTlhfeA
Wait so this isnt the serpentine belt?
