Default whats left to do in maintenance

i have a 97 ls400 with 182k miles. recently did timing belt water pump and all required. fixed the PS leak and transmission pan leak. changed all fluids also.about to clean the throttle body and replace the PCV.

is there anything else thats easy and inexpensive that needs to be done at this mileage that i could do myself? thanks

what does "and all required" include?

spark plugs, plug wires, air filter.
bleed out the old brake fluid and cycle in new.

Put leather conditioner on the seats. They could always use that!

I can think of lots of smart things to do that are inexpensive and would make a big difference in either reliability or comfort in how the vehicle rides & drives!

● replace the $40 transmission mount that is almost surely broken at that mileage (make sure to get this part from the dealership only)
● replace your likely worn out strut rod bushings (also about a $40 part from dealership only)
● replace your ECU caps before they leak and ruin the ECU ($20 in parts)
● replace the positive battery terminal, they develop hidden corrosion from dissimilar metals ($15 from dealership only)
● replace the Engine Coolant Temperature Sensor ($50 - use the real Toyota part - can make a big difference in gas mileage)
● remove the troublesome fuse link from the cig lighter socket if you depend on this socket for phone charging, etc.
● clean all the weatherstripping thoroughly with mild soap and then rinse a couple of times with water and then apply genuine Shin-Etsu grease

Mine has about 5K more than yours. I'd refresh the tranny, differential and bleed out the old brake fluid. MY ECT sensor was going south so that was another good fix.

thanks! im defenitely doing the transmission mount! strut rod bushings have been done. and as for the leaky ecu, im not too much of an electrical person. where can i get that done?
ill also look into ect next! and what did you mean about the fuse link for cig lighter?

the fuse link fails in the cigarette lighter, leaving it inoperable, after removal, the 12V socket is still protected by a normal fuse. - this repair is only really necessary for people who depend on their cig lighter 12v socket for something important, such as a cell phone for someone in sales, for example - otherwise, you can skip that until such time as it goes out, if the socket is not critical to you.

In my case, I have to have my phone charger, so I went ahead and did it, but I probably use my 12V socket more than most folks, between the phone and the inverter for my laptop.

Register with your ClubLexus name and you also get a discount! There are more websites, but I'll wait for more informed people to chime in haha.

yes

the tiny fuse link I am referring to, is inside the 12V cig lighter socket - there is a thread or two somewhere on here on how to take it apart and remove it, I am too lazy to search for it tonight - lol

but that is the tutorial I followed, a good one on here with many pics

Yes. I use Rockauto all the time. They are the cheapest supplier of aftermarket parts by far. And you can buy Aisin,Denso and Koyo branded "aftermarket" parts, which are the exact ones you would get from the dealership.

all of these below are legit, as is RockAuto

● Sewell Lexus
● Lexus of South Atlanta
● Carson Toyota
● Park Place Lexus
● Lexus Parts Now

however, with RockAuto, keep in mind that the vast majority of their parts are aftermarket, and not up to Lexus standards of quality, unless they specifically mention Aisin or Nippon Denso or other Lexus OEM brands in the part description.
