Default 2007 RX350 Serpentine Replacement - Anyone Tried it?

My car is now over 100K and I believe the belt was never changed (I bought it at 90K) ... I found the below link on how to do it. Looks straight forward ... Just wondering if anyone has tried it and if the they could add to the below instructions. Thanks!

yes it's straight forward...the link has pretty much everything you need. I took a couple of pictures of the belt layout just in case and the job took about an hour. If i have to do it again it'll take about 15mins.

Did mine on the 2007 this past weekend.

There is an additional pulley to the left missing from the first photo.

If you have skinny hands it could take you as little as 5 minutes to change - with a cold engine.

It took me about a 1/2 hour.

As for tips...

I found it easiest to go over the water pump pulley first, the "vane pump" second and then back to the top right and around finishing at the tensioner.

A 14mm ratchet won't fit for releasing the tensioner - you will need a box end wrench - the longer the better.

Good luck!

Just finished putting this on ... took less than 2 hours and that is because I had to draw out the belt map. Coluccim map is the most accurate.

I still went ahead and made a belt loop diagram and took some pics ... It looks a little daunting at first and I almost did not do it but once I loosened the tension-er the belt came off no problem. At that point there was no turning back. I started from the top and worked my way to the bottom. Took less than 10 minutes to put the belt on and I did refer to my drawing a few times as well ...

A couple quick notes ... You will need a flat wrench (14 mm I believe) ... You cannot use a socket on it with a ratchet ... Not enough room. Also ... Make sure you have plenty of lighting. I had my office light which worked well.

Found out the hard way ... I am glad I had a boxed end wrench. Thanks for the post.

Good job!

Yes, the photos in the write up are missing the idler and power steering pulley (vane pump?) to the left.

Mine looked like the second diagram I posted, just more compact from left to right.

Great DIY! Regarding the DIY link on the OP's first post, I have a question regarding the "5mm bi-hexagon wrench". Is this the same as an Allen key? What is the purpose of this wrench? Does it keep the tension loose, so that one can remove and replace the belt?

Also, what brand belt is everyone using? I'm thinking about using the gator back belt.

Thanks guys.
