    Removing the Air Filter

    Hello guys,

    OK first of all I know my dignity is shot to hell asking this question I'll work on that this spring and summer! I checked to see if there was anything in the 1,000 page pdf manual for my van, and all they had was about half a page dedicated to the air filter. They act like this is as ez as taking it off a 80s Corolla. lol There was NOTHING on getting this thing off and replaced! Blow compressed air or just replace air filter. That was it!

    I'm having problems getting that silver thing off in the pic. I managed to get that duct off, thinking I could fake the rest, but aint happening. Any tips on how to get thing off and replaced?

    At this point I'll go the extra steps to make sure things are in good working order. I'll work at getting things cleaned up too.

    Thanks for any and all help in this matter.

    Re: Removing the Air Filter

    Don't bother with "the silver thing" you don't need to remove it.

    Air filter box only needs to be opened enough to slide the filter out (although you do need to remove the air intake hose, as you have already done). There are four clips on the lid (well, four from stock they have a habit of being lost or removed). Unclip. Squirrel the lid up. Scoot the old filter out and work the new one in. Be sure it is seated properly (hard to do 'cuz ya can't see). Put the lid back on. Put the clips back on (they have a habit of preventing you from seating the lid, too). Sounds fast. ISN'T!!! Allow an hour, no kidding! Easier on a 3Y van, FWIW. Also easier if you have super-skinny hands and strong skinny fingers.

    If you weren't considering a K&N "lifetime" filter before, you sure will be now. Guess what my vans have.

    Re: Removing the Air Filter

    Yeah, I've been working on these vans forever, and I still cuss like a sailor every time I change an air filter . My hands and fingers are big so I usually use a long slot-tip screwdriver to get in there to unlatch the clips. Then I lightly lift on the front and use the screwdriver to pull the hanging hook part of the front clips away from the lower housing. Once the fronts are clear I hold it high enough to prevent accidental re-clipping of the fronts, then get the backs. If your air tube isn't old and hard, you should be able to tweak things enough to drag the filter out from the front. If your air tube is old and hard, then it'll probably crack and you'll need to get a new one. I don't know what hell Toyota was thinking when they stuffed that filter down there but somebody sure had their head up their rear end. Don't worry about your dignity (it cracks me up though) because at one point or another I'm sure all of us have determined changing air filters to be impossible on these things. Tim

    PS: After putting the new filter in, before latching ANY of the clips, use a flashlight and a long screwdriver to make sure none of the hanging clips ended up pinched between the upper and lower filter housings. Only then should you latch them. I usually use the screwdriver to latch 3 of the 4 clips.

    Re: Removing the Air Filter

    Thanks for the quick replies!

    Good to know I wasn't out in "left field" on this one! Looks like I'm going to get a mirror and light to see what I'm dealing with. I really couldn't see the two outside clips. I uncliped the two inside ones. I assume I'm dealing with 4 clips? What exactly will I gain by unfastening the two nuts from the bottom of the filter? I'm thinking nothing much?

    The K&N filters sound VERY appealing and will look into them. Any connections are welcomed. I thought my Fram filter that said "12000 miles between tuneups" sounded sweet! Not now!

    Yeah I don't what Toyota was thinking on this one, and really, not a word on the manual.

    Re: Removing the Air Filter

    There's 4 clips (at least there were originally). The clips are the only things you need to undo (no nuts). Like llama said, removing the air tube helps, but isn't necessary. The rest is just determination and anger motivation. For me, things like this only get done when I develop a certain degree of anger . When I get into that mode things get done quickly............but I also tend to bleed (or at least feel the results for a few minutes afterwards) .

    Re: Removing the Air Filter

    I do find removing the air tube a pain but useful.
    It is hard to get out and such, but you can take the wires connected loose fairly easily.
    This gives you an easier ability to seat the filter easier and without any damage while putting it in.

    The hardest part if you remove the Air tube is removing the air tube...

    This will allow you to see how dirty the box is and the ability to clean it if necessary..
    I do recommend doing this the first time anyhow beings you have not looked in there before and do not know a thing about it.

    Re: Removing the Air Filter

    If it runs rough after you are done either you cracked the air tube or one of the many vacuum hose connections in the vicinity has slipped off

    Re: Removing the Air Filter

    Running good! Feels like I'm finally making some progress on this!

    I wanted to respond on a couple of things above;
    The nuts I was referring to were these two. This is from looking up from the bottom. The nuts are on the inside of the air box.

    But then you have a nut on the outside of the box;

    So I just went with provided advice and got everything squared away. The forth and final clip I had to deal with was rather interesting. Pic is below.

    I never did get this one fastened and will just find a replacement C clip that I can rig on the front outside corner. I managed to get the air tubes reconnected with a lite layer of lite lub on the mating surfaces of the tube. Everything went on easy with this and should be easy to disconnect too, but will see.

    Thanks all!

    Re: Removing the Air Filter

    Hey y'all! I was just looking at the air filter for the first time and as I was trying to get it back in, there was a rubber seal that doesn't seem to fit around anything. I can't figure out exactly where it came from and I am worried about not putting it back in the right spot. It looks like it should go around the edge of the filter, but like I said, it is too big and won't fit right. Any thoughts?

    Re: Removing the Air Filter

    The only seal in this area is what comes formed into the filter. If you found something left over from before, it's likely off the old filter & I'd consider it junk. Tim

    Re: Removing the Air Filter

    thought i'd pass along some potentially good info that will probably save you at least some time and effort changing air filter. first time replacing air filter today and quickly understood why everyone says it's a pain. the clips get hung up getting the lid open, and hung up on the old filter and new filter and getting it back together. looking around my shop for help i grabbed two small mini bungees and hooked them over the clips (part that hooks down under lid) this kept the clips up and out of the way and i could concentrate on getting the box open and filters swapped out.

    still had to remove the air intake hose to get enough room. and the process is still a pain but getting the clips out of the way up front really helps.

    *additional tip* mini bungees need not be tight just enough to keep the clip hooks up out of the way. if the bungees are too loose - tie a knot or two into them and it'll be the right length

    also my wife has a thin wood dowel with a hook at the end to pull down our window blinds - this wood dowel was great at getting at the far right rear clip - releasing the clip / hooking the bungee / releasing bungee and re-clipping

    Cool Re: Removing the Air Filter

    wow.. this really kicked my butt!

    couple things I learned.

    1.Remove the air hose if you can! I tried doing this without removing and it was impossible... for me at least. DO NOT recommend. Mine was very stuck to the metal bits, but then I just rode around all day, got it nice and hot and pop! No problem getting both sides off and back on. I just removed the side closer to filter though.

    2. If you can swing it, BUY a K+N filter. Part is 33-2009 and cost me $60 at autozone. ya pricey, but if it keeps me from messing with the filter for a couple years... YES PLEASE. Also the K+N has a very low profile, so very easy to slip in. The one in there was double the height and a pain in the ass to get out.

    3. The hooks did snag on the back, i just overbent it a nudge and it stuck in place long enough to get to the filter in.

    4. find a friend with long skinny hands for the back clips... or a deft flathead screwdriver. they are a little goofy

    now if i can just get the darn windows to roll on the way down...

    Hope this helps!!

    Re: Removing the Air Filter

    User1 - those nuts you were looking at actually hold the base of the housing to the frame, taking them out would only have made your task harder.
    And for what its worth the 2 nuts on the bracket attach to rubber mounts that love to separate when you try to remove them.
    Those little rubber isolated mounts are NLA, so all the more reason to leave them alone
