Toyota Sienna Care & Maintenance



  • I have a '04 with 112K miles; my local repair shop is recommending along with the timing belt replacement to also have the water pump done. They are quoting around $600 for both; should I have the water pump replaced or can I just stick with the timing belt? THX...

    I paid $ 200 to have the timing belt done on my 2000 XLE-3ish years ago.Work was done at a Toyota dealership.I don't know why the newer model would be so much more expensive

    Just had water pump and timing chain done; cost me about 650.00. I semi trust the shop that did it. The labor is the problem with this as they have to take off so much just to access the water pump.

    I have this as well, Also, every now and then it just won't start. Leave it alone for a day or two and it starts just fine. Dealer was no help. Hours of googling seem to suggest the solution is carb cleaner in the Idle AIr Control Valve, or as a last resort replacing the valve. Has anyone tried this, and did it work?

    Cleaning the IAC valve took care of the problem. I found the fix on Edmunds and faxed it to the repair house.

    I have a 2005 Sienna with 99000 KM (60,000 miles?) and I just visited the local Toyota dealer in Cancun, Mexico. I asked about the typical or recommended interval between water pump changes. (All my experience is with belt driven water pumps.) The response I got took me by surprise. The service representative stated the water pump fitted on my model of Sienna is electric and essentially they replace it only after it has failed. I immediately questioned this so he pulled out a diagram of the 3.3 liter V6 and sure enough it showed an electric water pump. Did the pump change to an electric type after 2004?

    Yes you should have that done as soon as possible, if you haven't done at all since you own the vehicle. Typically because of the labor involved, the water pump is right there when they service the timmimg belt, so you can "kill 2 birds with one stone" so to speak. My recomendation is to use a mechanic that you trust rather than the dealer (for they are much pricier than other mechanics- unless offcourse you still have warranty on the vehicle.

    It's better to be safe than sorry, the brakeage of the timmimg belt will ruin your engine. Trust me I fell in the same thinking with a nissan that I owned, but this time they were right. I didn't replace it, when it broke, it ruined the valves permanently. (a very expensive job) I ended up getting rid of the car :cry: :cry:

    If the timing belt fails on a 2001 Sienna XLE at highway speed of approximately 70mph, will it harm the engine components such as valves, etc, or will the vehicle simply lose power and come to a controlled stop? I have heard that the 2001 Sienna has the type of engine that will survive a timing belt failure without causing any other engine damage. Is this correct?
    Also, I have just turned 100,000 miles on my 2001 Sienna. I know the maintenance manual calls for timing belt replacement at 90,000 miles. My local Toyota dealer is telling me that the timing belt on my 2001 Sienna should last for 300,000 to 400,000 miles or at least 15 years. My van is running perfectly right now. Should I believe what the dealer is telling me, or should I have the timing belt and water pump replaced now at 100,000 miles?
    Thanks for any help.

    Get the belt and pump replaced according to the schedule - which it appears you have already passed the 90k point. An engine always "is running perfectly" when the belt breaks. Belts and pumps are cheap compared to an engine replacement of 5-7 thousand $.

    By the way neither of these parts lasts to 300,000 miles.

    I have a 2004 XLE FWD, and I just replaced the battery. From everything I could determine online, 24F is the correct size. Based on good reviews in Consumer Reports, I bought the EverStart Maxx 24N at Wal-mart. Only after I got it home and started installing it did I realize that it's about half and inch smaller in depth (front to back), and thus the top bracket is way to big. I used some wood pieces to make the bracket fit tight, but was wondering if anyone else has had this problem. I can't remember ever having this problem before with other vehicles. Should I be concerned?

    I went on-line and found the specs for the BCI Group Numbers, but they list the sizes as "Maximum Overall Dimensions", thus I guess smaller is acceptable.

    Thanks for any advice anyone has.

    Funny thing is once I had the opposite problem - the battery was just a tad too big.

    I think you'll be OK as long as nothing works itself loose. Check it each time you check the oil.

    I just had the struts replaced, under warranty, on my 2007 Sienna XLE Ltd AWD. The left front strut was making noise and Toyota advised that upon inspection they found a leak in the right front strut also. In addition, the steering rack was leaking. The car has slightly less than 19000 miles on it. Toyota told me that they verified that the problems were "factory defects" and covered under warranty.

    Does this make sense to anyone? Anyone else experience this kind of problem with a supposedly super-reliable vehicle such as the Sienna?
  • ateixeiraateixeira Posts: 72,587
    Don't complain, I'd be glad they covered it, no questions asked.

    Don't tell them about your side job as a minivan rally racer. LOL :D
  • I had the same problem with Sienna 2004. As I drove it out brand new from the Toyota dealer in 2004 and got it in front of the driveway, I noticed an oily patch under the front left tire. I checked and saw it was coming from the strut.
    I took it back to the dealer who with a smile had the strut replaced under warranty.

    Recently, in april 2009 after 80K miles I started hearing a persistent knocking sound in the front left side. I checked the strut and found what looked like a leak. Took it to Toyota who said the strut had leaked and needed to be replaced. They said it will cost "between 355 and 800$" because they may have to change other parts related to the strut.
    The problem is they did not have the strut in stock. They had to order it. We have been waiting since then and no replacement strut has shown up yet. They called me this morning to say the part is still backordered and that they dont expect it soon !!! I think I am going to go to a local garage and get an OEM intalled except you have to do both sides when you change for another brand of struts
  • ateixeiraateixeira Posts: 72,587
    I was gonna say, it's out of warranty so just get some Monroe Sensatronics installed at your local shop. You can probably do both sides for that price.
  • My son threw a golf ball up into my 2009 Sienna exhaust pipe and we cant reach it. Turning the car on and gunning the engine didn't send it out. Any ideas on how to get it out and is it dangerous to drive? Thanks.
  • MaryTNMaryTN Posts: 2
    Have you tried a shop-vac? On a steep hill?
  • Thanks for the suggestion. I tried it but it did not work. I think the ball might be into the muffler.
  • ateixeiraateixeira Posts: 72,587
    Kids these days... ;)

    I guess once it's hot enough the golf ball will melt in the muffler. Per wiki:

    They usually consist of a two-, three-, or four-layer design, (named either a two-piece, three-piece, or four-piece ball) consisting of various synthetic materials like surlyn or urethane blends

    Not sure if any of those will damage the metal muffler as they melt. Or if the fumes will be toxic? :confuse:

    Any chemists around? What happens to surlyn and urethane as it melts?
  • Talked to the Toyota guy today and he says it shouldn't be an issue even if it is in the muffler but could make some funny noises. I drove the van today and thankfully didn't hear a sound! It is interesting about the golf ball melting. I guess only time will tell.......
