    Belt up until model year 2006.

    Chain from 2007 onward.

    Not sure of the interval because I have an 07 with a chain.
  • My 06 Sienna LE has a peculiar driver side wiper problem. Somehow the driver side arm stopped rotating while passenger side arm continuing it's normal course and then moving over the stopped driver side arm and get stuck. I did untangle them and found that the nut securing the driver side arm was loose. I tighten it up as much as I could but again after about 100 miles of driving under rain the problem recurred. Again I tightened the nut and after 100 miles it was loose. Any one know what needs to be done? TIA.

    Can't speak to this particular wiper problem but if the problem can be solved with keeping the nut tight then just get some of the liquid that does this at the hardware store. I've forgotten the name. Just be sure to get light or medium strength. They have different products and some would make it damn near impossible to loosen.

    I recommend that, too.
  • I just replaced spark plugs on my 2002 sienna.Three plugs in the back are little difficult.when you stand infront of the vachile look on the rear right side of the engine, there is a little space that you could put your hand and feel the coils.
    use a 10 mm socket to remove the careful not to loose the rubber gromet.Before you loosen the coil remove the wire harnes.There is alittle clip on the wire need to press on the clip while pulling to unlock it. once you remove the coil and stem use a spark plug socket by inserting the socket and extention first then the rachet.
    You could do two plugs from the right side, the third one you need to access from the left.There is a little hose on top of the left side plug, you could pull it up and move to the side.Same with the ground wire behind. let me know how you make it.
  • I have a 2002 Sienna LE with 72,000 miles on it. I bough it used with 56,000 miles.

    The vehicle runs good but, I was thinking about getting a Transmission Fluid change and Timing belt work done. The quotes here run at $650+Tax for Timing belt and $80+Tax for Transmission fluid change. Transmission fluid flush costs $165+Tax.

    I see than some of you have mentioned Timing Belt can wait until 90,000 Miles. What do you say about 2002 model. Its 7 years old. And also can you advice if Transmission fluid drain and fill is sufficient or should I get a Transmission flush done.

    I don't have much knowledge on these. Any advices welcome.

    What does the owner's manual say?

    Also, what does it say about age? The van is 7 years old. So if they say 7 years or 90k miles, you're still due.

    I have an 00 and did the timing belt about 2.5 years ago at 90k.I think I paid about $300 for it though.There is a place here on edmunds about maintenance which will give you an idea what it should cost
  • The repair shops say - that the water pump needs to be replaced when they do the timing belt. They say, if the water pump breaks down later, it would be a pain as they have to redo a lot and labor costs would be high. Any ideas?
  • jprocjproc Posts: 133
    Like I said mine was done 2+ years ago and they did the water pump as well.My memory still says about 300.I checked the edmunds maintenance site and they said it should cost you about $220 to have the timing belt changed.I really don't know what a water pump goes for.
    Mine was done at a Toyota dealership which was running a special at the time-still I think 600 sounds way too much.Try Pep boys see what they would charge you for a water pump

    My 2005 Sienna has a burnt-out bulb almost monthly! It's usually a different one but we've had some repeats. Has anyone else had frequent taillight, brakelight, and headlight outages? :(
  • I have a 2002 model with 100,000 Miles. When I come to a stop a strange noise from under the van. Any idea what this could be? .

    2000 Sienna: This is a recent problem: The parking/tail lights do NOT come on when turned on with the switch - only the headlights come on. When the brakes are applied, ALL of the lights (including the front parking lights) come on. I have checked all of the fuses - Although I didn't expect to find anything since they all work at some point. Any clues? Thanks.
  • On a 2002 Sienna , where is the PCV valve located and how hard is to replace it?
  • Thanks guys. I will check with the auto shops and ask them to just do the timing belt and leave the water pump out for now.

    One tip I'd say it to replace them in pairs.

    Usually the 2nd one fails right after the first.

    So if a tail light burns out, replace the other side at the same time, else you'll be doing it again a week later.

    I have an 06 LE with 64K miles, everytime I bring it to the dealer and ask if these need replacing he says no. They did "clean" the PCV once. Every other car I have ever owned has had it replaced before 60K. When is the PCV and fuel filter due to be replaced on this thing?? Is it a major hassle to replace the fuel filter so they don't want to do it as a preventive maintenance issue?

    Here's a word to the wise, or at least I hope it is:

    We purchased a 2007 Sienna new in April of 2007. We purchased the prepaid maintenance from the Toyota dealer when we bought the car. It covers scheduled maintenance for the first three years.

    We just took the Sienna in for scheduled 15,000 mi. maintenance. This is our fifth visit since we've owned the car. Every time we've been in, without fail, the dealer has tried to get us to agree to pay for items that they "recommend". Today's nut would have been $329 if we had agreed to it. It included draining and refilling the transmission fluid, among other things. The only "extra" I've agreed to, in a moment of weakness, was a new cabin air filter, and I probably didn't even need that.

    There isn't a manufacturer in the world, unless you're plowing snow or pulling stumps, that requires a transmission service such as this at 15,000 mi. After a brief and polite discussion we finally were able to make it clear to the service adviser that the only work we wanted them to perform was that which was covered under the prepaid plan. This includes any maintenance required by in the Toyota warranty book, including oil change and tire rotation.

    I guess they're just doing their job trying to make a few extra bucks, but it's darn annoying to have to have this discussion every time we go to the dealership. Bottom line: beware of dealer service extras. Don't agree to them unless you think you really need them.
