I bought my son a 2009 Lexus RX350 with 150k miles on it. I am trying to establish the maintenance record for it. Here is the recommended maintenance L-MMS-09rx350.
First of all, how to reset the maintenance light, bingo!!
Found a guy is changing the power steering fluid.
Programmed Homelink buttons.
Purchased map update on Ebay for less than 10 bucks and updated the map. Another guy does a video for RX400h, it is exactly same as RX350.
Install a new battery into the remote key.
Flush the power steering fluid. This guy has a better idea, at least has more viewing.
Engine air filter changed (12/03/21).
Cabin air filter changed (12/03/21).
Replacing the steering rack boot
Here is a complete process to replace the tie rodsteering tie rock.
Found a very good video explains why the passenger side boot tend to break easily.
This guy gives an overview of the job, it is quite informative.
This guy shows replacing the boot a slightly different way.
Overall reminder is to mark the bolt for the correct position when we put it back on.
This guy does it in a crazy way way,
On an Toyota Avanlon.
Replacing the cooling oil line, hopefully, I will not need it before I sell it.
replacing the VVT-i oil line
This video is much better. I am going to follow this video to conduct the fixing.
I may need an E8 Star socket to remove the stud.
Measuring the proper automatic transmission fluid
It seems to be an intuitive practice, but it can get more complicated than one can imagine. I am documenting what I find out.
Firstly, shall we test the transmission fluid level with engine on or off?
According to this document honda-ATF, the engine shall be turn off to measure the ATF level.
But, it is the different case with Toyota/Lexus brand.
According to the report, it seems to leave the engine on to test the ATF level. BUT it is VERY vague.
This guys's second video shows he is testing the ATF on a Highlander, which is equivalent to RX350.
I think the question is still up in the air until I get some professional validation.
I have found another video also echos that for Honda vehicles, the engine needs to be hot but off position to measure the ATF level.
Change the automatic transmission fluid
Here is the forum site for people to discuss.
This guy shows a video on change transmission fluid and filter.
This guy shows how to examine an RX350.
This video looks promising. It is for Toyota Highlander, but it is same as RX350.
This guy shows on 2008 RX350, provides some follow up testing.
Change rear differential oil
Here is a very clear video, easy to follow.
We need regular ATF fluid for the rear differential oil.
This guy shows how to properly use a pump to pump the rear differential oil back.
Just another good details video on this project.
