Tips for new-to-me GX 460 owners: Immediate fixes, checks, and things to look out for. (1 Viewer)

[Green4Gulf]

Hey Ya'll,
I just got myself a new-to-me 2013 Lexus GX 460 Premium (that I paid way too much for). I bought this vehicle sight unseen (IDIOT!) with low mileage and a good interior. Today I am going to scope out the secondary air injection pump and see if a service has been done on it since the Lexus website showed my vin didn't have any service campaigns or recalls. Anyways, what should I and any other new-to-me GXer be on the lookout for? What else needs an immediate fix? If anyone has a good master list, that would be GRRRREAT! Thanks!

All depends on your maint history and mileage. If you post those, plenty of good advice and some bad to be had here.

460's have only a few common issues so there's not much to do preemptive. You could change the radiator if you're over 125K to avoid any SMOD issues. There have been a lot of reports of coolant leaks from the valley gaskets so make sure you flush early and often and stay on top of trans flushes. Lexus doesn't push that much so they get skipped even by maintenance minded owners. Mine had been serviced at lex for everything, including batteries. Had every 5-10-15K service, for its first 135K but they never flushed the tranny for some reason. Or maybe it's just not listed on the 60K service they did, but in any case, trannies go more than engines in these so you might consider drain and fills between services. My shop does a flush for only $225 though and that's better.

And watch all this idiots videos: www.wastingtimeinthewoods.com He bought his 460 sight unseen also and it's worked out pretty well ; )

Verifying that the secondary air pump does not have the original filter.

Coolant related items are good service points. Perhaps my ’12 was an outlier but water pump started heavily leaking at only 38k miles. It was covered under powertrain warranty at the time though. Keep an eye on timing cover oil leaks… I’m gonna say like 95% of them probably don’t need to be repaired if they occur and just cleaned up. Brake cleaner and rags are cheap if no noticeable oil loss between changes and it isn‘t ending up on my garage floor.

I’m at 68k miles. I’m gonna change all the fluids soon and do a thorough inspection. I’ll definitely be on the look out for any valley gasket leaks. Thanks!

It definitely has the original filter. I’m going to call Lexus tomorrow and see if I can get the work done. The filter looked to be in good condition, so I can wait on an appointment with the dealership. Thanks!

I’ll be sure to be on the look out for those. My coolant tank is half full, so I’ll have to do some investigating. Hopefully it’s nothing. Thanks for the links!

Buying a Pedal Commander should be one of the first things you do. You'll appreciate it Every. Single. Time. You. Drive.

The accelerator mapping in these is horribly conservative.

I remember looking at one of these some time ago. I check it out again. Thanks!

Congrats on your GX! Welcome to the form!
Personally, and we've done this with EVERY used vehicle we've purchased, go get a COMPLETE service. including all fluids. Have them check ALL hoses and anything else they may have a list for.
Now you'll have a datum point to start all your regular service maintenance from.

Thanks! I'll be servicing all the fluids soon and having everything looked over. From what I've seen so far, everything looks to be in great condition. Now all I have to do is comb the forum for my mods list.

"Useful" mods depend on how you plan to use it. Tell us about how you plan to use it, budget, terrain, etc. For example, if I was "budget conscious" and planned light wheeling my mods on order would be 1) Pedal Commander, 2) Crawl Control (and MTS while you're at it) 3) skid plates for the dangly bits, 4) tires 5) lift. Oh, and a good compressor... If you don't plan to wheel much, but plan on long road trips, etc, that list would change.

 

[Green4Gulf]

So I checked my service records on the Lexus website and noticed the secondary air injection service campaign (JLG) was performed around 50k miles, but it still had that little grey filter in it, so I’m prob just gonna go ahead and put the Uni filter on and take the old one out.
@re_guderian I’ll start out with some light wheeling for sure, probably go with some tires as my number 1, was looking at the 17” fj steelies, but I do want to be weight conscious when it comes to my wheels and tires. I’ll be using my stock suspension for now and would like to utilize the spare tire slot, so I gotta keep that in mind when getting the tires, if not both tires and wheels. Everything I do has to be budget friendly for the rest of the year , well, maybe .

 

[re_guderian]

Despite what you read here, your spare doesn't "have" to be an exact size match. Look into the CC/MTS sticky thread. 500 bones for both is the best bang for your buck at not getting stuck, or getting unstuck...

 

[Rednexus]

I would also suggest a full transmission fluid exchange (with pan drop and filter change) as part of your fluid replacements. Lexus says the factory transmission fluid is "lifetime" but, IMO, it really needs to be done every 60K, so now is the perfect time to do it. You might have to call around to find a shop (whether dealer or non-dealer) who does that kind of service and uses the correct fluid (Toyota/Aisin WS or a WS-equivalent fluid like Valvoline MaxLife, which is what I use).

 

[Green4Gulf]

@re_guderian that CC/MTS option is attractive. I will be upgrading my rear air suspension to shocks at some point so buying the CC for the air ride will almost be a double purchase if I did it now. I can add the MTS now though, I believe that’s what I read in the forums, they can be added separately?
@Rednexus when I get to it I’ll be draining all fluids an changing all filters. This isn’t a daily driver, but won’t be kept in the garage either.

This is an awesome reply!
Similar to what I post to other new owners who want to go nuts on their rigs with mods.
Develop an "end game" of what your goals are for your rig.
Also, unless you have a pretty open budget, plan out your build in stages, example:

1. Tires and wheels.
2. Suspension. Reverse 1 and 2 if you're planning larger tires than will fit at stock height.
3. Skids plates and rock sliders. I suggest this before bumpers. You never now when on a simple trail you may bounce hard off something unexpected. Ask anyone on this forum who's done any trails.
4. Bumpers
5. Fun stuff: roof rack, lights, winch, etc.
6. And if you're planning serious off roading, lockers and gears.

Good luck and have fun!

If you don't have the OEM Class IV hitch you can fit a 265/70/17 or 265/65/18 in the spare tub and an otherwise stock GX with 1 inch larger all terrains can do a lot of work off road.

I have the OEM hitch

 

[Banandalorian]

I have the OEM hitch

Then you might be able to fit either of those tires. The official diameter of a 265/70/17 is 31.5 inches but different tire brands/models will vary from the measurement. My Pirellis measure 32 inches and won't fit (or won't fit without deflating, smashing the tire into place, and contacting the sway bar). But I know plenty of people on here have fit those sizes with the OEM hitch. There are a few threads on here about this topic.
