Definitely nicer to work on than some of the V6's mounted sideways where you have to remove the intake to get at the back three plugs.

[@4DIYers]

Oh I agree. I had a Pontiac Bonneville 3.8L years ago, couldn't see the rear three plugs. And I remember the old Dodge Caravans having to go on a hoist to get the rear plugs.

Thank you for the Torque wrench specs very helpful

[@4DIYers]

Happy to help!

[@keelothedoberman]

Great video, thanks! If you have the factory supercharger the driver side one closest to the firewall is kind of a pain, you need to disconnect a few things to get in there. The other 5 are a breeze! Easiest plug job ive ever done. Thanks for the clear video!

[@4DIYers]

Thank you for the kind words and feedback!

[@charlesmcgehee3227]

Exactly the information I needed to brush up on. Well done video. Thanks. Sure is an easy engine to work on. AISIN has really made a beautiful V6 here.

[@4DIYers]

Thank you and happy to help :) I have plenty more tutorials on this truck too and more to come as well.

[@kazekagetilo]

Thank you bro. I changed them pretty good! Thanks to you. When I did it man. The rubber insert that goes inside the sparkplug socket got stuck with the sparkplug and it was a pain in the butt to get it out of there. At the end carefully I put my socket on my extension and hammer it down softly got it in there then unscrew the sparkplug remove the rubber insert and screw it back on the engine. It worked out pretty good. Just if it happened to anyone. Thanks again

[@4DIYers]

No problem and thank you for the feedback too! That's a common problem with those rubber inserts. A mechanic's claw can help with those.

[@stevanrose7439]

The new spark plug sockets have magnets 🧲 in them. If you don’t have one get one.

[@duanehallsr.6028]

If you take the rubber out of the socket, then loosen the plugs and use a piece of hose to finish unscrewing the plugs

[@urban__dictionary5225]

Great Video! My car started misfiring Wednesday afternoon and I about shit myself… se your video and it helped a ton! Got it running within 3 days! Used the same Bocsh plugs and worked out great

[@4DIYers]

Thank you and happy I was able to help!

[@edwinoliveras8221]

Very helpful video. Now I geel more confident so , soon I will be replacing the old spark plugs on my 2002 Tacoma. Thank you ! Your friend from Puerto Rico , Edwin Oliverss

[@4DIYers]

You're welcome! The plugs on these are fairly straight forward. If you do run into issues where they're hard to remove, I also have a video on that as well.

[@stevanrose7439]

This was easier then I was making it out to be. I was over thinking it. Although I have worked on cars and trucks for many years. This was the first of it’s kind. So I was making it out to be more than it is.

[@jamessilva1999]

I agree with previous comment. Exactly the information I needed! Along with all the key details. Thanks.

[@4DIYers]

Awesome to hear and thank you :)

Great video did my first tune up today 👍

[@4DIYers]

Thank you so much and glad I was able to help!

[@dcppcp]

Your videos are very well done and to the point. Thank you. I bought some Bosch Iridium plugs 9651 to install and the box says 27 ft-lbs for the torque spec which is more than double the factory spec of 13 ft-lb. Do I still use the factory spec of 13 ft-lbs?

[@dutchman7216]

Thankyou for sharing that. I'am going to give it a try.

[@MatthewWilson-w3m]

My 3.4 has a sticker to only use twin ground plugs . You used a single ground plug which Toyota does not recommend. Is there a difference in performance?

[@4DIYers]

There's a lot of people that make a big deal about this. I haven't noticed a difference, it's not a high performance engine.

Thanks for the video, very helpful

[@Snipervenomaz]

26 never change a spark plug in my life hopefully , I get it done right lol

[@4DIYers]

Best of luck! It's more intimidating than it actually is. I have a video for seized plugs if you run into any issues.

[@tonyrowe1455]

Its not too hard

[@robertstewart3964]

Never change when the motor is still HOT

[@potatopotato6066]

Thanks this looks similar to a 1st gen v6 tundra I'm gonna color coat the wires and sharpie the color on the respected ignition coil

[@jimmyp587]

This video was a great help!

[@zrivs]

thanks, install was a breeze especially since my after market intake doesnt take up nearly as much space

[@4DIYers]

No problem, happy to help! Do you notice much of a difference with the aftermarket intake?

[@zrivs]

im not sure, the 1st owner put it on before i bought the truck. @@4DIYers

[@Oscarthegreat290]

On my Toyota, you can’t reach plug number 6 (rear plug on driver side). There is a metal tube in front of it that looks to be a/c refrigerant. Any ideas?

[@lilianahenry4572]

Excellent, excellent video.

[@4DIYers]

Thank you :) I have plenty more Tacoma tutorials too if you're looking for anymore repairs.

[@buildingconsultants1854]

"No-seize" also lubes the threads.... no eating up those aluminum threads

exactly. no need to roll the dice on that stripping

[@kingcruzfishin]

Why do you remove the wires from the coil pack? Can you do it with out removing the wires?

[@MajDuty]

I was not able to get mine to torque even near the recommended 14 ft lbs. I'd get about to 6 ft lbs and it wouldn't torque any higher, but the wrench WAS still turning. Fearing I was going to strip it out and felt they were snug enough, I tightened them no more but I was perplexed by this. All of them were like this and I tried two different torque wrenches. Since they are not holding anything mechanically I reasoned 6 ft lbs was sufficient. We'll see!!!

[@brendanschroeder1862]

Did you change them while you’re engine was hot?

[@MajDuty]

@@brendanschroeder1862 not even warm

@@brendanschroeder1862 yeah, a 2000 Tacoma I purchased new

[@brendanschroeder1862]

@@MajDuty interesting. I’m gonna say maybe your torque wrench was off then. Since it was consistent spec for all them.

[@04tacomaguy1]

I can't get to cylinder 6 all these brackets and fuel line in the way I don't know if I put it back together wrong last time or what but it's so cramped

Thanks Bro!!💪🏼

[@ever2gut1]

Woah, how's the truck run? I know there is a sticker to use dual electrode plugs and the ones you took out are also dual. Wondering if the single electrode made any difference for you

[@4DIYers]

Runs fine. Some people get super critical about "what the engineer" recommends. Engineers make plenty of mistakes and people fail to realize this is an underpowered V6, it's not a high tech engine. It has a waste spark system, so each plug fires twice in the 4 stroke cycle. Using a single electrode will most likely have a lesser service life than compared to a dual electrode, therefore requiring a replacement sooner.

[@ever2gut1]

@@4DIYers I work with engineers so I totally agree. Some of them don't even own cars so it can be quite scary having them make decisions. Fair enough, shorter lifespan it is

[@MajDuty]

I just pulled mine. OEM, dual electrode, seemingly typical NGK - 233,675 miles! While I don't recommend this, it is some impressive date, I think

[@akorahmaniazar]

Well single prong I used and my engine ran pretty rough for a while then a misfire happened. Going back to the recommended double prong.

[@carlspackler9550]

Man, you can tell they salt the roads in your area.

Maybe you know better than me but I have 99 Toyota 4Runner 4x4 with 219000 miles on it and some guy wanted to trade it for a 96 Toyota Tacoma v6 3.4 engine 5 speed manual what do you think should I trade it ?

[@philfrancisco2708]

same truck same engine so if you need a truck go for it

[@potatohamlin5242]

it should be the same for all 5vzfes right

[@4DIYers]

Yes it should be very similar.

[@lowrangeoverland9013]

thanks 👍🏆💯

[@4DIYers]

No problem!

[@theschuntz]

Why did you disconnect the battery cable?

[@4DIYers]

I didn't disconnect it for the video. The truck wasn't being driven until it was ready for the road so I just disconnected it, sat for about 6 months.

[@Soycochodeguerrero]

You should disconnect the battery 🔋 other wise you’re going to get voltage on your brains 🧠 hahah

[@vadex_gaming7269]

aren’t you supposed to use dual electrode plugs?

[@4DIYers]

It’s not a race car.

[@scottpeterson4802]

Dual electrode is what is recommended on the engine. At least on the 2004 3.4L Tacoma.

[@eliotnavarro9212]

i thought the spark plugs had to have a double ground does this not matter?

[@4DIYers]

Some people are really picky about it. It's not a high performance engine. It uses a waste spark system, so if you're using copper plugs, it may wear them down a little quicker.

[@LotusJones]

The Toyota engineers are picky about it. That's why they put a big sticker on the engine. Many people have had rough idle and poor performance going another way. Others seem to do fine. Why take the chance?

[@jctfujvreyu3202]

Do you have to have a torque wrench

[@4DIYers]

No, I almost never use a torque wrench unless it's something critical like a sensor, bearings, and a wheel just to be safe. But I would recommend it if you're new to such a job. Once you become comfortable with the feel, then you can get away without using one.

[@Hever73]

SO HOW MANY SPARK PLUGS DOES A TACOMA 3.4 CYLINDER V6 HAVE?

[@philfrancisco2708]

6 plugs and 3 wires with 3 coil packs

[@davidtrevino5211]

I thought NGK plugs work better on Toyotas ?

[@4DIYers]

I haven’t had any issues with these. This is not a high performance engine.

[@LotusJones]

Your manual specifies NGK or Denso - dual electrode. Some have had problems with other makes and single electrode.

[@johnfitzpatrick4873]

Chee hoo, monologue voice is kinda hard. But thank you.

[@nordicpride9708]

Great video. German spark plugs in a Japanese engine 🤢

[@ciprianomateocastaneda380]

[@ervinsagaysay439]

Don’t follow the specs for tightening the coil pack bolts!!! In the video he says 69’ lbs. I snapped my bolts!!! It’s 6-9 not 69!!!

[@4DIYers]

I said 69 INCH POUNDS, not foot lbs. Listen to the instructions carefully.

[@M4Nathan007]

.044 gap btw

[@4DIYers]

Manufacturers do not recommend gapping platinum spark plugs.

[@noahlevor7652]

@@4DIYers I bought factory plugs from toyota, do you know if they are pre-gapped? Is the .044 the correct gap? It doesn't hurt to check them. Even though you don't need to gap them sometimes they get dropped in the parts store or in shipping and the part hanging over the electrode can get bent. Ask someone who works at a parts store...

[@jyoung2393]

The torque will change with your 12 inch extension, it's significantly less than what you set it at

[@4DIYers]

It doesn't and it's been proven many times. There is actually a video of this on KZbin using a torque wrench calibration tool.
