    I put my owner’s manual in a safe place. So safe, I can’t locate it. :(

    Time for me to do my pre-winter maintenance. I just hit 20,000 on my 2020 Tundra. I plan to

    • Do an oil and filter change
    • Note: just changed the air filter.
    • I plan to bleed the brakes.
    What other maintenance would Toyota recommend for 20,000??

    Too many, but not enough....
    Have you done rear diff yet? If not I would. I would put a new pcv as well for 8 bucks. Wouldn't hurt to suck out your power steering fluid and fill with new.

    I think that pretty much covers it. There's not a lot of maintenance before 50,000. I don't know that I'd even bother bleeding brakes at only 20k.

    Check the cabin air filter maybe. Mice and bugs find their way in there in the Fall and Winter.

    Checking the cabin filter is a good idea. It can't be hard to relace and not an expensive item.
    Bleeding the brakes has more to do with time rather than mileage. Five years is the maximum I usually go. In my past, I have not been so diligent, and the insides of the calipers rusted. The rebuilt calipers I purchased never seemed as good.

    rotate tires, pour 2 cans Berryman's B12 injector cleaner into a half tank of fuel, wiper blades, drain and fill coolant, too old. Brass drain valves on both sides of block can be accessed behind tires through wheel well with steering turned, way up in there. Just crack them open to drain the block. That coolant turns acidic with heat cycles over time and eats head gaskets. Also replace the radiator cap, the rubber seal fails and gets stuck inside the water jacket or pump.

    Honestly, just the normal oil, filter and air filter change is all that’s needed at that age and mileage. Tire rotation. No need to swap parts that haven’t even had a chance to give you some service life.

    I am going to take a six-hour drive to the Finger Lakes. I planned to add two cans of BG 44K Fuel System Cleaner Power Enhancer 4. It was recommended to me by a gentleman on this board who is one of the engineers that formulate Shell gas. I use it in all my cars.

    I forgot to add tire rotation. I do that in the fall when I do my oil change.

    Don’t bother with the brake bleed/brake fluid change. You can buy brake fluid test strips to test for moisture. If the fluid looks golden and there’s no moisture you’re golden.
