Toyota Sienna Care & Maintenance

    The oil filter is in a little bit of an odd position:

    When looking down into the engine compartment, look to where the oil dipstick is. Look 3-4 inches to the right and then down 8 or 10 inches (rough guess), under the silver heat-shielding. The filter is parallel to the ground.

    It is easy to remove if you use a special type of wrench - a "cap" or "cup" wrench that fits over the end of the filter. Be very careful to get the right one. There are two slightly different types, one with 16 and one with 17 flutes (I think that's the right term). It may be 15 vs 16, I don't remember the specific count.

    The oil change on the Sienna (with that wrench) is *really* easy. I find it a bit laughable that Toyota considers it beyond the grasp of owners to do on their own (like other manufacturers).

    I just changed the oil today for the first time on an 04 Sienna. Removing the oil drain plug was easy, but taking off the oil filter was a bit messy. The hot intake manifold prevented me from putting enough torgue to loosen the thing reaching from above. I had to jack up the front end and reach it from below. I used instead a strap-type filter wrench and it helped.

    I have a question for kinct: did you notice whether there was originally a rubber gasket between the oil pan and the drain plug? I did not see one - perhaps they forgot to put one on at the factory? The service manual clearly suggests a new one be put on after each drain & refill, which I did (the drain plug gasket costs 72 cents each).

    Try using the cap/cup wrench on the filter - *if* it is one that has fluted ends (e.g. Toyota/Fram filters, vs Purolator/Wix filters which are completely circular). That makes getting that nasty little filter off much easier. JUST MAKE SURE TO COUNT THE NUMBER OF FLUTES! Fram filters have a different count than Toyota filters (IIRC Fram has one more). With that wrench, this becomes the 2nd easiest car to change the oil on that I have ever had (older VW golfs/GTIs (86/87) were easier still). It's really easy.

    Re the gasket between the oil pan & plug - be careful - I bet the original gasket was still attached! The gaskets are some sort of hard composite material, not rubber or a soft metal. They really like to stick to the oil pan.

    Thanks for your advice. I'll see if I can find the right cap-type wrench. As to the drain plug gasket, you are probably right about it sticking to the oil pan. I looked for it all over the place, and I thought the raised ridge around the drain hole is part of the oil pan. Oh well, I'll take care of it next time I do the oil change.

    I currently own a 1998 Sienna LE, and I was wondering how often you have to change the timing belt. Thanks so much!

    90,000 miles. At my dealer, they charge $219. I would also get them to change the belts - no additional labor - only the cost of the 3 belts.

    The SERVICE MAINTENANCE REMINDER LIGHT came on after 7,500 miles. I looked in my service manual and found out that it meant replace the engine oil. Since I had changed the oil at 5,000 miles, I wanted to reset the reminder lite. It was nowhere in the manual. Do any of the 2004 sienna owners know how to reset the light?

    Have any of you replaced your rear shocks? I have a '99 LE and I am going to replace the rear shocks and front struts. The rear looks like I will have to pull the each side panel from the cargo area. Anyone been through this yet?
  • filodfilod Posts: 189
    Dave, thank you. This is very helpful for us who change their own oil in between the maintenance reminder.
  • freebirdfreebird Posts: 77
    In case anyone else is interested in this - the rear shocks are easily accessible from inside the van. It took about 5 minutes to change both rear shocks.

    OK, I've scanned all the messages on changing the plugs on the Sienna. But I have an additional concern: one of the three front side ignition coils seems to have a slight leak (there is a trace of a black oily substance on the valve cover). Are these coils filled with oil as an insulator? Or is the insulation inside the coil a solid material? I'm assuming that if the oil is the insulator then I'll have to replace it (I'm sure it's $50+). Comments please?

    Hello - I'm a new poster to the Sienna board and I hope someone can help me out.

    I attempted to DIY the 30K antifreeze change on my 2001 Sienna yesterday. I followed the standard procedure of heating the engine with the heater on high, turning things off, and draining (after allowing things to cool off) via (i) first removing the lower radiator hose; and (ii) then realizing that there's a handy valve on the other side of the radiator.

    I didn't keep track of how much liquid drained (no, I wasn't draining it into the sewer), but made sure that no more liquid drained from the valve or the lower hose attachment. When refilling the system, it only took 1.5 gallons, versus the 2.75 gallons that it should take according to the engine specifications.

    I've gone through earlier posts on this board and now realize that there are engine mounted drains, as well as the suggestion that I should drain the rear heater line. Given this knowledge (I know, I should've checked this board first), I have the following questions:

    1. Is it possible that the engine block holds one gallon of fluid. Will opening the engine valves release this fluid?

    2. The rear heater appears to use only one quart of fluid (based on the capacity specs for rear heater vs. no rear heater vehicles). If this line holds significantly more fluid than this and I choose to drain that line, which hose (there appears to be two) do I remove?

    3. How do I find and access the rear engine drain valve?


    4. I now have a cooling system that's 1.5 gallons of Prestone ethylene-glycol (green-diluted 50:50) and 1.25 gallons (approx) of OEM Toyota fluid. Can these two coexist for a while or should I be re-changing the fluid (once I figure out how to fully drain the system) ASAP?

  • Jack, did you ever get any answers? I have a 2004 Sienna and the bumper plastic seems so soft. Only had the car a few months and there are scratches that I wouldn't expect in a +/- $30K vehicle.

  • No - I just use some silicone on the bumper to get it looking nice - then it slowly fades. My LE has the gray bumpers.
  • davenowdavenow Posts: 171
    look into getting the clear plastic (like bubble- wrap, but a lot more expensive) for your vehicle. I think trdparts4u caries them for us...

    I'm thinking of getting these, but looking for the price to come down...(I just purchased a LTD recently and i'm still licking my wounds, but I'm happy) :)
  • The service maintenance light on my new Sienna XLE AWD keeps coming up. I have completed only 4750 miles of local and highway driving in NJ. The service manual recommends a service once every 7500 miles. Does anyone know why this light comes up ? Is there a potential problem ? Do I need to have the service done sooner than 7500 miles ?
  • I would like to know more about rustproofing treatments for Sienna's 2004 and over.

    Do you need to do any treatment. What is recommended.
  • I am would like to know too. I sent an email to toyota but they did not respond.

    anyone responded to your message?
  • deepandeepan Posts: 342
    there are typically 2 kinds i think. One is they apply a coat of tar (or similar product) to the underside and its pretty much for life although yearly touck ups are recommended. $350
    The other is spraying oil which is a bit cheaper but has to be done yrly atleast once in 2 yrs. $75)

    i wouldnt let the dealer do this as i undertstand the markup is higher.

    I have done this practically every yr especially if you live in a cold wet climate.
  • Does anyone know where I can purchase an after market cabin filter? I priced one today at my Toyota dealer and it was $30+ .
  • davenowdavenow Posts: 171
    ~$18 plus tax & shipping
    and it's not aftermarket!!! (true toyota parts)
  • My 2004 Sienna has about 4000 miles. I need to change the oil before 5000 miles (according to the manual).

    Should I go with Synthetic oil for life on this van?

    Also, should I always go with 5W30?

  • davenowdavenow Posts: 171
    For "do it yourselfers" I would use fully-synthetic 5w-30 weight motor oil. the money is well spent in good quality 100% synthetic oil.
  • I need to change the oil on my new Sienna for the first time--but I can't find in the owner's manual anything about how many quarts it takes. Can someone enlighten me? Thanks!
  • davenowdavenow Posts: 171
    5 quarts of 5w-30 weight motor oil with filter change.

    Make sure no sand falls into plug sockets when you change your plugs. Engine could be get ruined.
  • todolisttodolist Posts: 2
    Has anybody changed lamps in their dashboard. Local shop wants $125 for the labor and I would like to save the money and do it myself.

    rust proofing is very important to do on any vehicle. All that salt on the roads just eats away at the vehicle. You should go to a dealership and get it done. I did. It's the best way to do it, you get a life time warranty and only have to do it once so it never costs you anything again
