Maintenance question

I’m at around 54000 miles on my trd off road 4x4 manual 2020 .besides oil change is there anything else I need to replace .
Dealer was saying fuel injection cleaning but I dont see anything in the maintenance interval for servicing fuel injection .
Another thing should I replace the power steering fluid and coolant ? The power steering looks ok but I can’t find anything in the manual about it . Coolant shows in manual to replace 10years or 100k . I have seen others replace earlier . Thanks guys .

 

I keep this thread bookmarked.

Probably front and rear differential fluid.

I'd inspect the brakes, cabin filter, and engine air filter, but you might not need to change any yet. How much of roading do you do? Any towing?

Power steering fluid wouldn't hurt to do, but probably isn't necessary. Coolant should be good for a while. Transmission fluid is debatable, some people like to change early, but technically you don't need to. Some transmissions were apparently underfilled from the factory, so it wouldn't hurt to do the check procedure, but if you do it's only a little more work to drain and fill.

Transfer case fluid is good for a long time. I just changed mine at 129k miles for the first time and it still looked decent. Front and rear diffs looked worse. Now that break in is done you can probably go longer until the next change.

Brake fluid would be good to change, but most people don't do it and don't seem to have problems.

 

Is it the same for a 4 banger. 2.7?

 

Is what the same for the 2.7

 

Sure. Spark plugs *may* be a little different, fluids should all be the same.

 

I feel dealer recommended fuel injection cleaning is only cleaning your wallet.

If you can do the work yourself changing out the fluids isn't all that expensive or difficult.

One item I feel the recommended service interval is too long is the coolant.

The only thing protecting the head gaskets is the inhibitor package in the coolant - it may "look" good, it may test good from the freeze protection standpoint but the inhibitors may be tired.

It is an easy job requiring just under 2 gallons of coolant (OEM preferred )and a piece of 5/16" hose.

I agree. I've read that the coolant starts getting acidic after about 50k. Not good on the head gaskets. I did mine at 50k and sleep well.

 

I go by time rather than miles for the most part.

I have an old Subaru (97) and change the coolant every 2 years.

 

Are miles or years more important for coolant? I have a high mileage 2019 with 129k miles on it.

While searching for an answer, I found this interesting article about Toyota cooling systems. https://automotivetechinfo.com/2022...e-coolant-sllc-and-cooling-system-components/

 

The usual recommendation is 5 years or 100K so you have passed both.
Interesting that after the factory fill is changed the recommended interval is 50K.

As I stated a few posts back, coolant is the unsung hero of head gasket life so I prefer to change it earlier than recommended.
