Thanks for these videos. I work on my own car's and video's like yours are very valuable tools!

[@VikingsGarage]

I appreciate that!! This is why I do them, if I’ve helped you save some money and learn something in the process, then my missing was accomplished!! 🤘🏻

[@richardmajewski3815]

After watching this video I was motivated to change these myself on my 2015 4Runner SR5. As long as I had the air intake system apart I also cleaned the sensor and the Throttle Body and replace the air intake filter. It took me a bit longer as I had to get a couple of specific tools and a magnetic spark plug socket with a long extension which had a total cost of around $50 and the cost of new spark plugs and PCV valve. There are more DIY projects in the future thanks to your channel. Thanks for sharing these tips with us.

[@wolfeadventures]

Just changed them on my 2011. Had 140k on them. Didn’t look too bad! Also only had to remove bracket holding heater core coolant lines, used zip tie to hold them out of the way. 4 and 6 took a few extensions and bit more time but very easy job. Only easier job is Corolla! Thanks VG. Your vids really help. Thank you.

[@peterkohler7259]

Thanks for the guide! There’s a story on KZbin of a guy with an 08 Tacoma (4-cylinder) who went 700k miles on the original spark plugs. He was on Toyota Jeff’s KZbin channel a year or two ago.

[@VikingsGarage]

Thanks for posting this, this was very helpful. I learned that I probably don't need to do mine just yet. According to the service records they were done shortly before I purchased with 79K, and I've put 65K on it myself since then. After seeing it here though, I'm very confident I can replace these myself without any issue.

[@jollytime0811]

Thanks man, followed your video along with a few others, and it was not bad at all. Changed the spark plugs and PCV valve. I did knock the air tube gasket into the engine when removing the secondary air injection pump. Fortunately, I found it but I recommend to anyone else to remove that gasket before removing that pump. I spent about 30 minutes looking for it, but everything else was a breeze!

[@VikingsGarage]

👏🏻

[@Aaron-gj2mo]

Thanks for great video. I use a short section of fuel line to install plugs. Push it in the end of the line. Holds it enough to start it and run it down all the way. Pops right off like wire boot.

[@VikingsGarage]

That is indeed a great tip!! 👍🏻

[@owenmiller9906]

Great video. I LOVE that include all the factory part numbers needed - super helpful! Note: Our 2011 Trail Edition with the 4.0L doesn't have the secondary air injection valves so the gaskets are not needed.

[@VikingsGarage]

That is correct! Thank you 🙏🏻

[@KendrasEdge757]

Yeah I believe the secondary air injection on the 4Runner 1GR-FE didn’t start until 2013. However, unless the gaskets are damaged, they’re not needed to be replaced when removing the valves for plugs or any other reason. Thankfully Toyota typically builds things correctly and knowing these have to be removed to replace plugs they made them out of metal and not some other material that would degrade from the heat and break upon first removal.

[@VikingsGarage]

💯 👏🏻 It was very well thought out.

[@michaelmcmullin1341]

[@MattBusman]

@@VikingsGarage thank you for your response! One more question… what type of gear lube and atf do you recommend? I don’t want to be a brand snob but I want my 4Runner to last a long time so getting the right brand is key for me.

[@VikingsGarage]

@MattBusman atf always Toyota’s WS . Not sure what you referring to “gear oil” ?

[@MattBusman]

@@VikingsGarage sorry it’s probably not the right thread, but I’m in the mood to change front and rear diff fluids-not sure if/when the previous owners did it. That’s what I mean when I say “gear lube”.

[@VikingsGarage]

@MattBusman oh I got you, no worries. If you want to do it the absolute best way: amzn.to/3vOcunw Otherwise any gear oil of 75w85 weight will do… often time I use amzn.to/3vTgZ03 That case should be more than enough for both front and rear differentials. Enjoy!! 👍🏻

[@Papolucho702]

Oil changes alone in most places in Vegas want $100+ Buy the oil, have a power wrench, do it yourself I did on Sunday morning, felt great lol Doing diff fluid today likely

[@VikingsGarage]

Totally brother, so much cheaper and most importantly , very rewarding! 💪🏻

[@KendrasEdge757]

Do you just replace your plugs / pcv valve at 90k on your 4Runners? Why 90k as opposed to 100k? Seen them failing around 100k?

[@VikingsGarage]

I’m a firm believer in preventive maintenance . Even at 100k they both still look good.

[@lcatalla7292]

Hey VG, have ever have to deal with code P2443, secondary air injection (AIR) system switching valve stuck close bank 2. My dash showing CEL with accompanying TRAC off and blinking all terrain icon. Changed gas cap and its kept coming back. Thanks!

[@VikingsGarage]

It’s not a gas cap, you need to test that banks emission pump aka Air injection pump. It’s probably stuck closed. I’ve seen it quite a few times, moisture gets in there and creates friction in the valves shaft. Just replace it!

[@lcatalla7292]

@@VikingsGarage my research leds me to understand Secondary AIR bank 2 is the driver side..right? I might just have to replace the pump.

If spark plugs are to be replaced every 120K then how often should the coil packs be replaced?

Thank you!! You most likely need a radio

[@ryanramos1303]

Thanks for the video. I just followed it to change the spark plugs on my 2011 4Runner. On the driver's side bank, center cylinder there was oil on the spark plug and the spark plug tube. I believe the spark plug tube gasket needs replacement, but could it be something else? Is oil leaking into the spark plug tube an urgent repair or can it wait?

[@VikingsGarage]

It’s most definitely the deal that should be changed with the valve cover gasket. “Is it urgent?” Some what , Can you wait a bit more? That all depends on the amount of oil leaking. Too much oil there is definitely not a good thing. Props for getting it done. 👏🏻

[@slopemaster9770]

Thank you for another great DYI video, much appreciated. One question, what are your thoughts on using anti seize on the spark plug threads? I used to use it on my 97’ 6 cyl Tacoma.

[@VikingsGarage]

👍🏻 It won’t hurt to use it!

[@jeremychrist]

Thanks for the video great info! Any recommendations on a broken nut/bolt (secondary Air injection tube) that connects to the the exhaust manifold (driver’s side). I sheered the stud when taking one of the two nuts off. It was completely rusted.

[@VikingsGarage]

Don’t touch it and you’ll be fine, for now. Otherwise either manifold replacement or broken stud extraction 🤷🏼‍♂️

[@rayduffy6172]

Great video, I have a question, is the air compressor valve that you remove on each bank the Idle Air Valve ? How would you clean that valve if it needed to be cleaned ? Thanks, Ray

[@VikingsGarage]

You mean the emissions pump valve… you can scrub and vacuum i spouse. We never clean those things. 🤷🏼‍♂️

[@jarbink7262]

Thanks for the tips

[@VikingsGarage]

You’re very welcome!!

[@mkm44]

I noticed you don’t use anti-seize on the spark plugs, or the PVC, does Toyota not recommend that? Also, I was wondering what your thoughts are on catch cans. You’ve probably seen the inside of engines more than other people do they prevent sludge from building up.

[@VikingsGarage]

NO anti-seize Sir! PCV, already comes with a thin layer of it. Catch cans are good/needed on boosted vehicles not under normal circumstances. Sludge buildup is a result of poor maintenance and owners neglect. Change your oil when recommended and you will be fine.

[@Treetopflyer777]

I know you’ve mentioned it in a recent video, but what’s the mileage between replacing PCV valve? Thx!

[@VikingsGarage]

At the Same time as spark plugs, every 110k to 120k intervals.

Good guide. Hey I want to convert my 22 orp 4runner to dual zone auto climate control. I ordered the climate control unit. The harness plugs right in. Turn car on and it lights up and buttons work except the fan speed never turns on and I don’t see temp either. Any idea if it’s something in software with techstream or a reset procedure or learning ?

[@VikingsGarage]

Honestly I’m pretty sure that it’s a different wire harness and or air con box assembly. The Dual climate control cars have extra motors in the air con box assembly that models without it don’t have. Last time I looked into this, that was the conclusion. 🤷🏼‍♂️

[@big659]

I’m a new sub cuz I love your videos! I have a 4th Gen 4Runner, but they’re basically the same. Couple questions- does your engine want iridium plugs where mine want copper? Also, I seem to remember being told to use dielectric grease on the coils. Is that necessary? I didn’t see you do it. TIA

[@VikingsGarage]

it does use iridium plugs, they all use the same spark plug( part number in the description of the video). dielectric grease on the coils would only possibly help if you’re having water/moisture issues, there’s no need for that. let’s not overthink it. welcome to the Channel!!

[@240sxdriver]

Have you ever encountered a 5th Gen 4Runner with a brake pedal that went to the floor in stages? I have a 2019 and noticed it would bite and stop at mid travel, and then out of nowhere it would feel like a seal broke and I would start rolling forward until I pressed to the floor. Please help!
