try it and it's simply outstanding! wow!
i used it today on my van and the results were amazing! took me a total of 5hrs. to wash, dry, use the clay bar and then wax.

the product really works!

    To summarize for this topic, I was looking for any input on routine brake care.

    I am due to check, clean, and lube my brakes. My plan is to disassemble my front pads, inspect and clean them, use disc brake grease on the backs and shims, and reassemble, bleeding a bit of fluid. For the rear, I will open and vacuum them, and possibly bleed a little.

    Does anyone have any additions? Any advice on "synthetic" brake fluid?

    i dont normally remove the pads/shoes to clean. i just vacuum/blow or and spray brake cleaner.

    what i started to do recently was use a very fine sandpaper and lightly sand the shoes at the back to remove any dirt/junk on the shoes. i also lightly sand the drums. some brake shops do this to remove the glaze on the shoes.

    because it usually isn't compatible with most brake systems. Also, check your warranty. Here's a link, you can read all about it. Rudy

    Thanks for the informative link, Rudy!

    By "synthetic," I meant Valvoline Synpower DOT 3/4 brake fluid. As the tirekingdom points out, DOT 5 is a synthetic-silicone formulation; I think the usage of the term synthetic is different here. Synpower fluid claims to be completely compatible w/ conventional fluids, and it does meet DOT 3, as required by my Sienna.

    There's a general discussion on this in "Maintenance and Repair."

    Has anyone changed out their PS fluid on their Sienna, and what technique did you use?

    For newcomers, be aware that the owner manual and reservoir indicate Dexron II or III as a power steering fluid. Technicians at my dealer recommended using a power steering fluid.
  • I have a 2000 Sienna with 41K miles on it. My wife usually drives it but I've noticed in the last month that I hear a light squeal just before the car comes to a complete stop. Also if I back up in the car (usually slowly) I hear the squeal when I put on the brakes. Is this an indication that the disc brake pads need replacing? I've replaced pads on other cars but I haven't tackled that chore yet on the Sienna. Can anyone give me some steps in removing the caliper and changing out the pads? Thanks! Also I read in another BRAKE section of Edmunds that squealing is sometimes due to vibration not wear, and you can put a piece of duct tape on the back of the pad to reduce vibration (& squeal). So even if it's not time to change the pads, I'll need to know how to remove them if I want to add something to reduce the vibration. If you want to send me some tips without posting them to the site, my email is Thanks again. John. Durham NC.

    I have a 1999 Sienna XLE with lower side panels that I believe are not metal. Over the last few years they have accumulated some scuffing, marring and general abuse. What is the best way to make these begin to look better? After I wash, polish and wax the vehicle and it looks so good I want to take care of these panels and I don't think that polish and wax are the answer. Any help?
  • Does anyone know where the 'third' coolant drain plug is located. One is under the radiator, another is next to the oil filter, but I can't see the third one. Thanks.
  • pjksrpjksr Posts: 111
    According to the Repair Manual, the third plug is on the right "cylinder block side cover." Remember, the engine faces the passenger side, and its left side faces the front of the van.

    To drain, they say to loosen the plugs (not remove); use ethylene-glycol base coolant; and use distilled water, if diluting. Capacity is about 11 qts with a rear heater unit, 10 without.

    Torques: Left-Hand drain plug 13 [N-m]; RH plug 7 [N-m].
  • Ok, thanks for the LH/RH info. I have the manual too ($145!!) but I just don't see the RH drain plug. I guess I'll just have to raise the Sienna and crawl under it to have another look around.

    I'm getting close and want to do the brakes myself (I do them on my BMW without too much trouble). Anyone done a brake job. Can you summarize the steps and/or post some pictures. Also, where is the best place to by discounted OEM Toyota parts?

    Thanks in advance...

    Dealer maintenance schedule suggests tranny fluid change at 30k...I could not find any mention of this in the owners manual.

    any help

  • I bought new plugs for my 2000 Sienna XLE, couldn't believe the cost. It looked like an easy job and I figured I save a few bucks by doing the job myself along with most of the other 60k maintenance. I replaced the first three in less than 10 minutes. The other three I am having a problem with. It looks like there is some kind of brace over them(under the black cover) but wasn't sure how to remove. Any one have any experience or suggestions with this? Any help is appreciated!
  • jeproxjeprox Posts: 466
    to you and anyone who thinks it's easy to replace plugs on the sienna - the answer is a big NO, not that easy! :) the 3 plugs on the front are easy but the 3 plugs in the rear bank needs a lot of work to get to them. the brace (black cover) you are referring to is the cowl, that big plastic piece needs to come off before you can get access to the plugs in the rear bank. you can try and see if you can reach the plugs but i doubt it with the cowl in place.

    give yourself about 30mins. to an hour to replace the rear plugs. :) this is mainly coz' you have to remove the cowl and put it back when you're done replacing the plugs.

    this is why dealers in my area want to charge over C$220 to replace the plugs on any sienna.
  • The cowl takes all of 10 secs to remove, but there seems to be something else in the way once the cowl is removed. It looks like a brace over the top of the plugs, but I am not sure enough to just remove it. Any thoughts?

    Thanks for the help.

    hmmm... 10 seconds to remove. :) that sounds too easy. :)
    i have to check my service manual when i get home tonight. i wonder if you are talking about the fuel rail.
  • jeproxjeprox Posts: 466

    visit this link and look at all the engine pictures (11th picture to be exact) and tell me which part is in the way.

    on one of the pictures (11th picture), you will see the cowl with sticker on it, that whole piece needs to come off for u to get access to the rear bank. this is why i'm surprised it took you only 10 seconds to take that piece off! :)

  • We may be talking about different things. I was talking about (in your 11th picture) the piece directly on top of the engine with the toyota insignia and the engine size markings. Are you talking about the piece with stickers that runs the length of the engine compartment right under the wipers? If so, I must not even be finding the plugs. Once I remove that cover, it only has two odd size screws holding it down, there is a long rod at least 1/2 inch in diameter above all three of what I thought were the plugs. What i think are the plugs have green plastic covers with a wiring harness attached. At first I thought they could have been fuel injectors under the green covers, but I have never seen fuel injectors with wires going to it. The rod that is in the way can be seen in your 11th picture sticking out from under the cover I described. I will have to take a closer look this weekend and follow all the plug wires to make sure I am even finding the plugs. I didn't even really have time last night to put in the other three plugs, even if they were really easy.

    At least the air filter wasn't too difficult!

    My last three toyotas were so easy to do everything, I even replaced a water pump and radiator in a tercel.

    The piece covering the engine, with "V6 Four CAM," etc, is the engine cover. In the 2002 model, which is different than jeprox's: To remove, you'll need a 5mm allen wrench for the 3 nuts, AND you need to unscrew the Toyota logo.

    The "cowl" is the black plastic that lines the rear of the engine compartment's top; where the wipers and brake reservior come thru. You will need to remove the cowl, along with, most likely, the intake manifold, to reach the right-side (rearward) plugs.

    I'd recommend a repair manual!

    Jeprox: is that engine cover a "mod," or is it pre-2001 OEM?
