60K mi all-fluid replacement tips on ‘how’

2020 4wd
60K mi
Mostly highway, some dusty conditions, quite a bit of very hot day driving, rarely off-road, almost zero towing, use 4wd occasionally in winter.

Without going into what sources I use to decide this, I am planning to change the following.
I realize this is controversial with a hundred opinions vs the service manual. This thread is not about that.

(I’ve been doing engine oil & filter every 5K, Pennz 0W20 synthetic)

Which ones need more than drain & refill (ie flushing)?
Send any important tips on how, and any gotchas if you will.
Also your opinion on preferred products.
I am too far to involve the dealer on most things (3hr drive).

trans
diff x 2
xfer case
coolant
brake
steering
what else?

Thanks and Happy 4th to all.

 

For diffs and transfer case I used Ravenol at 30K and will again around 60K https://www.blauparts.com/toyota-tundra-transfer-case-differential-fluid-change-kit.html

Subbing to see about the rest since I'm coming up on same mileage.

 

This is what my intervals are:

Brake Fluid - Flush every two years. Dot 3 synthetic.
Transmission - Drained and filled 3 times after breakin. Drain and fill every 25K to 50K after. You can use WS. I use Valvoline Maxlife ATF.
Diffs and Transfer case - Drain and fill every 30K. Use whatever fluid you want, as long as it meets toyota spec.
Coolant - Drain and fill every 3 years. Toyota SLLC
Power Steering - Flush every 2 years. Dex 2/3 sythetic ATF. I use Castrol Transmax Dex VI, which is compatible.
Engine oil - Drain and Fill, change filter every 5K.

Thanks Chip-
Can you describe the flushing?
It’s more than cracking the brake lines at each wheel and allowing them to drip til empty?
Something more active than that?
And the PS?

 

Nothing needs a flush, which are for toilets, not cars. Unless you drain and there is some serious crap in there which would be next to impossible at 60k miles.

Drain and fill all of it. For brake and power steering I drain the reservoir and refill every couple oil changes. Both fluids are very cheap and easy to get to. I would use the block drains for the coolant if there isn't alot of corrosion on them.

I use Motive pressure bleeder with BA10 master cylinder adapter after three years. Also use dot3 synthetic fluid

 

Brakes are very easy if you use the tube into bottle method. Get a clear hose/tube that fits the bleed port and run it from caliper to a bottle. Fill the bottle with enough brake fluid to keep the hose submerged to prevent sucking air into the caliper. Baste out the reservoir of old fluid and fill with fresh. Starting at the rear passenger side (furthest from reservoir), you crack the bleed port open, pump a few times until the reservoir is no lower than minimum fill line (keep topping off the fluid) or fresh fluid runs into the bottle. Tighten the bleed port, then move to the next furthest caliper (usually driver's rear). Repeat with each caliper while topping off the reservoir with fresh fluid. Just be careful you don't drain the reservoir and don't overfill the bottle.

With this method you'll never suck air into the lines or calipers, and you get clean fluid in all the lines.

 

not bad, pressure bleeding far easier and quicker one person job. To each their own

 

This is also a 1 person job. I installed my Z06 Brembo BBK on my Tesla, and swapping lines, calipers, and flushing the lines myself took about 2 hours.

The Motiv pressure bleeder has worked decently in the past, but I've had moments where the seal wouldn't be tight enough.

 

that’s fair. I did buy the Toyota specific adapter and worked great, could do all four in less than an hour.

 

As far as brake bleeding goes, I did mine with a Mityvac. I would suggest not just doing the reservoir because the fluid closest to the brakes will be dirtier than the fluid in the reservoir since the dirt collects at the lowest point. After I bled all 4 and drove around I felt the pedal wasnt has hard as I remembered so I used the brake bleed option on TechStream which activates the ABS module while you are bleeding and that stiffened the pedal up more.

 

Does the public have access to the specs & recommended brands for all the discussed fluids, or is that only in the service manual?

 

For brakes, I did in fact mean bleed. I use a fluid extractor with a bleeder attachment and it becomes a one man job.

I do the same with the power steering. Yes, it's more involved than a drain and fill, but I like clean fluids and components.

 

I've used a Lisle 75000 Vacuum pump to bleed brakes. Also helps make it a 1-man job. The Lisle vacuum pump can be used for other diagnostic purposes too , pretty useful tool.

 

The dealer parts desk offered this info:

Tfr Case 1.6qts BG brand
Front Diff 2.2qts BG brand
Rear Diff 3.8qts BG brand
PB 1qt brand?
PS 1qt brand?
ATF 5qts Toyota brand
Coolant

Posts 2 & 3 had good tips.

 

Yall would cringe if you knew my opinions and thoughts on coolant, brake, and power steering fluids.

Transmission, at least once every 100k miles.

Diffs, at least once every 50k miles.

Engine, every 5k.

And yes, I’ve taken many vehicles over a 100k and a couple over 200k with no issues.

For brakes get a Mityvac MV8500 suck the master cylinder out then refill after at each wheel bleed the wheel until clear fluid. Put some grease around the bleeders if in the rust belt. The front diff use hose up threw the engine bay to fill it.

O’Reilly’s -

Got Valvoline;
-dot3 brake fluid
-‘power steering fluid’
Those had no confusing choices.

However, the ATF was a different story.
I grabbed one that had the Toyota spec “WS” shown, then asked the teenager at the counter to see which one his computer suggested for my 2020 4wd SR5 and he said “Wrong” and pointed me to the red Valvoline (they only had it in quarts so I skipped that for now)
There were 3 or 4 colors all with different descriptions, I confess to some confusion now.

Thinking this is probably the right one.
comments?

It appears the only truly acceptable coolant is Toyota brand.
Think this is truly Toyota, or is it Chinese crap-clone?
(I’m 3 hours from a dealer & they won’t ship.)

Power steering fluid is incorrect. Correct fluid for our power steering is Dex II/III ATF. This is the Toyota part number 00718-ATF00.

 

Thank you sir.

 

I am not seeing Dex II/III power steering fluid.
You say Dex II/III ATF - so I suppose I can use the same ATF that I'll be using in the tranny - the one I mentioned before;
This ATF says on the label; "for Toyotas, Dex II/III and WS spec."
let me know if I'm on the right track.

https://www.oreillyauto.com/detail/...tomotive-truck-2020-toyota-tundra?q=atf&pos=0

 

Thats correct Dex is an ATF type, our power steering system does not use power steering fluid it uses ATF. I can't comment on aftermarket fluids for those. I personally used that Toyota part number for my power steering fluid and use ATF WS in my transmission.

Interestingly on the OReilly website when you search for Valvoline ATF filtered for the 2020 Tundra, it "Fits" but when you put it in the cart it does "Not Fit".
I asked about that and they say it comes up that way b/c Arnley was the original ATF for this vehicle but Valvoline ML D1 will work.
Reliable info? Hard to know.

 

Arnley?

 

just noticed its not full synthetic but a synthetic blend.

You can keep it simple and just use Toyota WS fluid, its not super expensive and then you're not mixing different fluids since a drain and fill is only about 4 out of the 12 quarts.

$10.80 a quart here
