Toyota Sienna Care & Maintenance

    No the seats cannot move to a different row.
  • I have recently purchased a 2004 Sienna that is due for its 60,000 major servicing...The dealership also strongly suggested throttle body service, power steering flush, fuel injection cleaning and cabin filter replacement...Does this seem reasonable? and if so , why is it not part of the mandatory Toyota maintenance schedule? Just discovered this site and quite like it.
  • My friend ran into this scam with her Corolla. I started looking at her dealer invoices and found she had spent around $1500.00 over three years in dealer BS costs.

    The cabin filter is the only one I know of that might be remotely legit - but check the manual. You can buy the filter on line and change it yourself, if necessary, in about four minutes.

    Find a reputable independent Toyota Specialist and follow the owners manual is always the best advice with very rare and compelling exceptions.

    Consumers Reports did an expose on this dealer BS sometime within the past 18 months.

    Best wishes.
  • I don't know where "Problems & Solutions 2004+" went but my problem is the car is only 3 weeks old and when I went to see how easy it was to change the air conditioner filter I found many seeds and a mouse nest on top of the filter. How do the mice get into that area? Thanks for any help.

    I know there are many seeds and leaves on my filter but a mouse nest? that's something you may want to keep an eye on. since the filter is located inside the glove box, my guess is that the mouse maybe coming from other part of the air filter system? near the engine?
    You should double check the car and hopefully the mouse is gone by now :)
  • Who makes the OEM oil filters for the Sienna 2006? Looks like it may be Bosch or Denso ? Which filter do you use?
  • Hi,

    I recently bought a used toyota siana 99 model. I want to know that how often (miles) i suppose to change the transmission oil. Is this really naccessary to flush it? My understanding is that just changing the oil and filter would be sufficient.

  • The dealer said that the difficult startup and low idle on my 2002 Sienna was do to a dirty throttle body. I found this site:

    with instructions on cleaning a 3.0 liter V6. Will this work on my Sienna? Anybody DIY to clean the throttle body?

    I want to avoid the $200+ cost they quoted.

    I just bought a 2006 Sienna, and the manual says I can change the settings so the vehicle does not automatically lock when put in gear, but I have tried their method several times, and cannot make them stop locking. Has anyone done it and exactly how did you do it? ;)
  • zizithzizith Posts: 11
    The manual says go see my Toyota dealer to make the illuminated entry lights change from staying on for 15 seconds to another time. I want 30 seconds. Is it possible to do it myself? Has anyone tried it yet? :confuse:
  • Detailed instructions for this can be found in the owner's manual and it seems quite simple.
  • zizithzizith Posts: 11
    Thanks for your reply, but I was using the manual to set it and the manual was missing a step. After setting the brake, then you MUST put the shifter into neutral, then continue on with directions. I had to go to the dealer, watch him read the manual, and add the extra step that it didn't explain clearly.

    Thanks for your post. :)
  • I plan to take my van in at 90,000 for timing belt replacement. I ask the dealer service rep if we need to replace the sparkplugs and wires while the car was in for service. She said the van had some special plugs that did not need to be changed unitl 100,000 miles.

    Is that true?

    Looks like from a labor standpoint, it would be cheaper to replace plugs and wires while we are replaceing timing belt.
  • My 2002 van is due for the 90,000 service which includes timing belt replacement. The dealer said not to replace spark plugs at this time.

    Should I insist the plugs and plug wires be replaced at this time? It appears to me it would cost less to have them do the work now while they have the engine covers off.

    Any suggestions on this repair???

  • caravan2caravan2 Posts: 198
    It is passed warranty, correct?

    If so, what would be the damage if you let the timing belt wear out let it break? I know in the old engines, it used to damage valves. I newer engines there is no damage when the belt breaks.

    I think it will cost quite a bit to replace timing belt. What is the quote you have?
  • Caravan2

    I think the timing belt change estimate was $285-300 plus they have a 25 point check, this also includes new drive belts.

    Another dealer told me the plugs in this van were designed to go 100,000 miles. They cost $10 each and have a coil per plug so there are no wires to replace.

    I may still have the plugs replaced when I do the timing belt change.

    Note: It's my wifes van, if the belt broke on her and left her in no mans land, she would trade the van asap. It is cheaper for me to take good care of van and hope it runs great for many more miles.

    Just changed battery today, battery was 5 years old and did not want to get stuck out somewhere in the cold.

    I just bought 2007 LE to replace my 99 LE that was totaled by a texting teenager. I read through the maintenance schedule and did not find anything about the timing belt needing replacement. I know the 2007 uses a new engine (3.5L), does this new engine need the timing belt replaced? Does it have a timing belt?

    I am looking for a service manual for My 2002 sienna. If any one have it on a'Cd', I would like to buy a copy.please post a message. thank you.
  • I have a 2005 LE AWD with about 37K miles. The struts that hold up the rear hatch have failed. The hatch is very heavy and the door slams very hard. Scared the heck out of us. If my son (7 year old) would have been standing near the back it would have crushed him.

    The service manager at toyota dealer hinted that this is not the first time they've seen this. Given the serious hazard I am guessing that toyota will do a recall. But in the meantime, please be aware of the risk. Do NOT let your kids hover around the rear access with the hatch up.

    I have a 2000 Sienna with 95K miles on it. When replacing my timing belt, my local mechanic also suggested to look into the water pump. He said the same labor can be used to fix the pump as well if it is also worn out, and hence I can save money in labor. Is it common practice replacing a water pump when replacing a timing belt? Please share your experience. Any help is appreciated.

  • dudleyrdudleyr Posts: 3,469
    It is fairly common to replace both. The water pump should last, but it is not too expensive for the extra insurance.

    Could someone help me out with my Sienna 2002.The engine wont stay after starting. Some suggested my altinator was bad.
    Has anyone had this kind of problem before.
  • steeltagsteeltag Posts: 2
    GoodDay all! I"m a new owner of a '04 Sienna LE w/36,069 miles. It was back-n-forth over the Odyssey and Sienna but the Toyota won due to the transmission problems of '00-04 Ody's ( motor mounts and electric doors too).

    There is a unpleasant odor coming from the vent ( not a/c usage) and I suspect it might be the cabin filter. I hear from others that its behind the glovebox, but how does one back there? I couldn't figure out how to take the glove box out/down. Could someone give me some insight on this procedure?

  • zizithzizith Posts: 11
    I just learned that if you drive your van around 5000 miles without changing oil, the "req'd maintenance" light goes on and stays on at the dashboard, I googled for help to learn how to turn it off, and my husband found the answer in the manual. (Oh, those computerized cars!) :surprise:

  • Hi:

    I have a 2004 XLE with a problem with the rear lift gate that I have been trying to get Toyota Canada to fix for 3 years. Mine only happens in the cold weather which we have a lot of up here in the 'frozen north'. I have had my struts replaced 3 times and it only gets worse.
    The NHTSA has an on going investigation into this problem. Here is their site:
    Just drill down to the 2004/2005 Sienna.

    Nice find.

    If you do change the oil before the light comes on, do you still need to reset it using that procedure?
  • mnrep2mnrep2 Posts: 200
    Yes the light comes on every 5K.
  • ateixeiraateixeira Posts: 72,587
    Cool, thanks for the tips.

    I bookmarked that one. :shades:

    Follow-up question - how do you reset the Trip Computer again? Someone told me the outer two buttons, left most and right most, but that didn't work for me. Any help? :confuse:

    Just got XLE w/ DVD last month. Today, while I was listening to my radio at front, kids turned on the DVD.

    Then, I just pushed the PWR/VOL knob to kill my radio, they shouted. It apparently turned off the DVD as well. After reading the manual and tested a few times, the "RES DVD Lock" on/off is to respond/ignore the remote.

    Now, how can I just turn off my radio meanwhile keeping the rear DVD alive?

    I guess to turn down the vol to 0 might be a workaround. Isn't it dumb?! :confuse:
