Serpentine/V-belt replacement
Hi guys. I'm the one that just changed the steering rack on the GX460.
The serpentine belt was off when I got it and I don't see a diagram anywhere under the hood and no manual in the glove box. Can anyone give me or link me to a belt routing diagram? There are WAY too many pulleys to guess, I'd never get it right. Thanks in advance, Wayne |

Thank you! I actually googled it and found it, much to my surprise. Google has gotten terrible for all the garbage on it. You search for a wiring diagram for an 02 Grand Am and it'll pull up an 05 silverado....just goofy!
Thanks though, that was exactly what I found. Wayne |

v-belt replacement
hey, everyone-
how difficult is a v-belt replacement? |
Usually pretty easy with the auto tensioners. I haven't looked at tensioner on GX but on another car a 1/2 socket drive us used to release tension and then I used a L shaped Hex key to hold in place.

I don't recall when this is recommended in the manual. Looks easy enough but my GX is my only source of transportation. If I had another ride I would change this out along with spark plugs and other mechanic DIY. If I got frustrated I could take my other ride to work but all of my needed work equipment is in my GX, I have played this game when I had my MDX and it is frustrating to move from one vehicle to another for me :sad: Simple things (subjective) become mentally difficult when it MUST be immediately accomplished and supposed simple things can become a hassle. I would really like to accomplish this on my own just for personal satisfaction. |
It doesn’t appear service guide shows replacement but shows inspection at each service interval. It says: “Drive Belt Inspect for cracks, excessive wear and oiliness. Check the belt tension and adjust if necessary. Replace the belts if they are damaged.” |
At 124K miles I prefer to replace it. If this breaks I am screwed.. .While Lexus is reliable, Belts and hoses have a limited life and yes there are factors on the wear. Just want to be proactive here. Probably a 1 time thing for me and piece of mind.

I would replace it too.
|
At 124k miles, you could also replace the fan pulley bracket too while you’re there. |
Looks awfully tight in there. I'm due to do mine in 5k when my rig hits 120k... I was eyeballing it awhile back and it seems like it might be a challenge just due to the lack of space.

I can’t say I have looked closely at what it would take. I would imagine you want to take lower skid off as well as the top plastics. With tensioner pressure released belt should be fairly loose. |
If you remove the fan, there’s plenty of room. I didn’t do the work but gave it to a friend when replacing the waterpump. I didn’t recall it took that long either. The old belt looked really good at 45k miles, no strays or micro cracks. It could be passed as new. https://cimg3.ibsrv.net/gimg/www.clu...7f376f5a2b.png https://cimg5.ibsrv.net/gimg/www.clu...18201f3ae.jpeg https://cimg6.ibsrv.net/gimg/www.clu...e58d75836.jpeg https://cimg7.ibsrv.net/gimg/www.clu...3d1d93bba.jpeg |
Why are the 2 belt diagrams above different?
