My “new” truck. Next steps?

Hi all, recently dodged a bullet after buying and returning a 2019 sr with a blown transmission. I then did all my due diligence and picked up my new-to-me 2017 SR5 5.7 4x4 in quicksand today!

It runs and drives PERFECTLY (compared to a ‘21 I got brand new a few yrs ago). got my 17 today at a Toyota dealership. It has 102k miles. It has had dealer performed oil changes every 5k and recommended maintenance up to 30k but that’s about it…. (As far as recorded maintenance)

can you knowledgeable folks please advise me some mechanical services to perform on my new truck?

-transmission drain and fill?
-t case fluid?
-coolant?
-spark plugs?
-seafoam treatment?

anything else? I’d like to drive this for a good while. Glad to be apart of this wonderful community again

 

Congrats on the new rig...

Transmission: Drain and fill every 60k or 6 years (w/Toyota ATF WS)
T Case and Diff: Every 30k
Coolant: Every 50k or 5 years (w/Toyota OE PINK 50/50 super long life)
Plugs: Plan on those at about 120k (OE only)
Power Steering fluid: every 50-70k (do not use transmission fluid)
Brake Fluid: every 3-5 years

Seafoam: I know some people swear by this stuff, but I try to just stick to the basics; so far, it has served me quite well... My '08 is over 265k now, and my '21 will be taken care of w/the same protocols (we'll see how that plays out)!!!!

 

Congratulations!! That's an outstanding truck! Like you suggested, swap all fluids, plugs and any hoses that look dangerous with cracks on the vacuum side... get a tune and be smiley ☺️! Let's see this best of yours!!

 

OP added images.

thanks for the suggestions, I will be doing the applicable services ASAP!

 

Are these sealed u joints (I come from Tacoma and 4Runner where they’re not) if they’re not sealed don’t forget to grease those as well

 

Congratulations on the new ride !

 

What does it mean? Extract by vacuum through bleeding screw only, do not force fluid into reservoir by pressure?

 

+1 for everything in post #2.
Additives: (seafoam, shit you add to oil, add to fuel, etc),.....if you don't really understand how something works, or what it really does/doesn't do, it's better to simply not use it, than to pour it in and hope or assume. Assuming a product does "something", or, "I use X and never had an issue", are not reasons to use a product.
It's not a boat from the 1950s. Don't use seafoam.
Changing brake fluid every 3 yrs is also a good idea that I don't see mentioned enough. It absorbs moisture, so it's good to change it every few years.

 

Good catch... I was flipping between my maintenance spreadsheets and that post; started to cut and paste, but then decided to just type and lost some attention to detail on that line.

There is really no way to do a brake fluid exchange w/o flushing the system. I've seen people 'turkey baster' the MC reservoir and then just fill the missing fluid, but that's a waste of time and money.
