How can I safely remove this?

Someone feel free to call BS on this as I'm not entirely sure, but I know that when I purchased my 2002 Sentra, the salesman told me that those pins are designed to melt quickly if there were to be an engine fire to have that piece drop and smother the flame. Not sure if this would be the same or not. I recall that back in the early 00's Honda was potentially having some problems with their cars catching on fire, so that may be why Nissan did that. Not sure if Toyota does that too or not.

See the attached for the Repair Manual information. I would use a flat screwdriver and stick it in one of the three notches under the center flange. Rotate the screwdriver to pry the clip out. You may need to pry at multiple notches.

Yes, that is what the underhood liner/insulation is for. I've removed them from cars for a period of time and don't notice any extra noise,or the paint getting damaged. Basically if you don't know the engine is on fire and the liner/insulation falls, it'll cause an eruption of smoke to tell you to alert you of whats going on and that you should get out ASAP. The same applies to todays vehicles too.

I was an auto engineer for 27 years and designed hood liners. Their only purpose is noise attenuation. They mainly absorb higher frequencies, like mechanically radiated noises from the engine.

For all those asking why you want to remove it... that's not the point! I wanted to remove mine to get at the washer spray nozzle (which still didn't work but that's another story).

So, here's how....

The liner clips are devious little buggers. Here's what the look like pulled out to give you an idea of what you're dealing with:


To pull them out, Narboza said to use a screwdriver and pry them out. I guess that would work but also break them. I have found a better method.

They look like this to start (with three tabs to hold the insulation in place):

If you try to pull the insulation off.. you'll just rip it or break the clip.

A better way is to bend the tabs back and then gently pull the insulation past.

This will make a slightly larger hole than original, but still not wreck it.

Now when you're ready to put the insulation back, bend the plastic tabs back and re-insert the clips. Just like before. Nothing broken - nothing replaced.

Hello all..

I registered just for this.. but honestly, it's probably about time I did, as I am a Sienna owner, so might as well :)

I'm in the same boat, as I was simply looking to check my washer nozzle and found I had to remove the heat shield. That's when I first came upon these horrendous clips. Before I attempted to remove them, I did a youtube search and found nothing. I even thought to take a video, but that idea didn't occur to me until I was in the midst of it and my phone wasn't nearby, alas.

Here's what I did. Hopefully it will help someone. I did pull the shield past the clips, which did cause them to slightly cut or expand the holes they came through. This is probably wrong, but that's what I did.
Now to get the clips out, I did this (saved me all but 2-3).. you'll notice that behind the 3 fan blade - like pieces, where the clip comes out the hole, there are 2 small pins, one on each side. These pins are attached to the retaining clips that are on the other side of the opening. What I did was use needle nose pliers and did my best to get both of those small pins out of the hole, where I could pinch them both with the pliers. This contracted the 'bars' that keep the clip in. Most times that enabled me to get the clip straight out. Other times, I was only able to get one pin or even if I got both, pulling on it only allowed one side / bar to come out. But even when I only got one side out, I was able to leverage it and get the whole clip out.



Could someone share where they bought new ones online, per chance? I'm also looking to grab a few for good measure..
God bless!

I am in the same boat. Windshield nozzle is missing its insides and I need to get in there to see if I can get it out and order a new one, or not. Still not sure, but at least I have an idea what is involved in getting the shield off. Thanks.

I will be checking Rock Auto on these items to see if they are available.

'05 Sienna here. I got it off, finally. Mine has the round pins and not the clover-leaf ones. Had to use brute force, but most of them came out without breaking. Wedge a small screwdriver underneath and then grab as close to the middle as you can with needlenose pliers and yank them out. I did it when engine was cold, but would probably be easier if it was hot and the plastic was a little more pliable. Pictures below of what then pins look like when you get them out.

After the insulation is off, you can pop out the old washer nozzles and replace with seems to be a fairly universal one and reattach the hose. Was $30 for a pair of them at local auto parts shop but I found them on Ebay/Amazon for as little as $7 or $8 bucks each. The Amazon page will also display plastic replacement pins if you need them in the People Also Purchased section of the page. But my insulation seems to stay up just fine with two less than what I started with.

So you are probably here because your windshield washer nozzle has lost its innards. I was able to get the 11 three winged clips off in about 10 minutes. It works best if the van is pretty warm so the clips won't break. Also if you do it in a darker area with a headlight (flashlight) on you can see the little tabs easier. I held the one of the 3 "wings" with the needle nose pliers and then reached in the with dental tool to push one tab in. Once you have one tab out of the hole a bit you reach around the other side and push the other tab in and the clip pops right out without damaging it. I only destroyed the first one when I was trying to figure out how they work. If you do destroy some the part number is 53326-08010. The dental tool also worked really well to push the tabs in on the windshield washer nozzle so I could release it and pop it out the top. The part number for the windshield washer nozzle is 85381-AE020. Good luck.
