How to change spark plugs on a Lexus GS 300 | 2JZ-GE (IS 300, SC 300, Supra)

[@viffer94]

Just changed the plugs and wires on my SC300. Crazy that Lexus runs the wires in that heat soaked channel on top of the head and then of course covers everything up with the throttle body and plastic to make sure it all gets roasted in that engine oven. Almost guarantees you’ll have to change everything out every few years. Having said that it is a 30 year old car so the fact that it’s still running and in such good shape is a testament to the build quality. But some of the design choices leaves me scratching my head.

[@theautochap]

I agree! A few other things that come to my mind are the placement of the oil filter, having the brake booster and ABS module as an integrated unit resulting in a 2000 dollar repair bill if either goes out, and so on. Luckily the build quality does save the day! Thanks for watching! :)

This is an excellent video. This really helped me have the confidence to do plugs, coils, and valve cover gaskets. 2002 gs300 with 130k miles, these are great cars. Thank you!

Bro this is the best video I’ve found yet, you explain everything to a T like “changing spark plugs for dummies” vibe you gave. A+ in every aspect and thank you bro 🙏🏻 your a whole different breed of KZbin help videos 💯💪🏻

[@theautochap]

Thank you for the kind words and appreciation. I like to make my videos as detailed as possible so people who are hesitant/nervous to work on their cars can feel more confident and at the same time save a little bit of money! Again thank you for watching! :)

[@johnbrothers4083]

Wow. Great job detailing the process. Better than others I have seen over my 60 years as a backyard mechanic. Thanks

[@theautochap]

Appreciate the kind words. Thanks for watching!

Very good video and explained very well. I just replaced the 3 coil packs, spark plugs and spark plug wires on my 2000 GS 300. Plus replaced the valve cover gaskets . I got a misfire on several cylinders. The spark plugs looked really rough when pulled out. Car , engine just turned 267k . Did timing belt /WP a couple months ago. Goal is to hit 400k with it. I have owned it 6 yrs. Best car built in my opinion. Again appreciate your video it helped me on the coil packs. Learned something new with the waste spark system. Pretty smart technology from Japan. 👍

[@theautochap]

Glad you found the video helpful! That was exactly one of the reasons I wanted to do the plugs, I got a random misfire and knew the plugs were probably drenched in oil and gunk. That’s awesome that you hit 276k I definitely plan to keep mine until the wheels fall off. Thank you for watching! :)

[@pavelbuchnevich1229]

@@theautochap Valve cover gasket leaking may be why they were drenched in oil. Should've replaced the gaskets too since you've pretty much done 90% of the work already. Just needed to remove a few more bolts to get the valve covers off.

[@theautochap]

@@pavelbuchnevich1229 actually did that too, it’ll be one of my next videos. Thanks for watching! :)

[@alexfarid5144]

Great video , very informative . Why didn't you wash the engine cover and timing belt cover while you had it off ?

[@d4b4y4re4kid]

Please explain why my bolt holding the coil is not catching on the bolt hole it just spins snd doesnt tighten

[@enuff2weturpantie]

Great video helped me out alot my first time doing a big job like this. Can you put a radiator replacement video

[@theautochap]

Hello! I’m glad you found the video helpful. I’m actually replacing the radiator but as a part of a bigger series where I’m rebuilding the engine, here is the first video in which I remove the radiator. 2JZ-GE Rebuild Part 1: How to remove cylinder head | Lexus GS 300, IS 300, SC 300 kzbin.info/www/bejne/f4O4c6CXodKKrsk In the next few videos I will be reinstalling a new radiator. I know that’s not exactly what you were looking for but hopefully it helps!! Thanks for watching! :)

What’s the last hose called @ 2:34 minutes in , I took mine off & it cracked need to replace just can’t figure out the name

[@slumppshotgun4968]

did u ever find iut the answer to this, i had the same issue the hose came iff in 4 pieces lmao

[@petesmith9472]

I replaced the coil packs and plugs in my Lexus GS300. I just can’t remember having to remove the throttle body etc. how time flies!

[@gideonbernthal]

You said you were going to make a video of replacing the wiring connection to the coil packs. I need to do this. I can’t find it he video please link it ❤

[@the2jzchannel]

Nice video good info! I replaced my 2jz spark plugs wire with the same NGK! Drives wonderful!

[@theautochap]

That’s great to hear! It’s definitely a pain with the intake being on the top but well worth the effort. Thanks for watching! :)

[@the2jzchannel]

@@theautochap Yeah it is a pain removing the upper intake manifold. I was wondering if your planning on doing a GS door lock actuators replacement video, and possibility a Lower Ball Joints, Rear main seal, and maybe suspension shocks and springs replacement video as well? Your videos are very informative and helpful for all Lexus GS Community. Definitely I can see your channel growing with more helpful and useful video like these for all GS community.

[@theautochap]

Unfortunately I replaced the front LBJs and the door lock actuators just before I started this channel :( but I just finished rebuilding the entire rear suspension and got some great footage, that will cover replacing the shocks! I plan to do my front shocks in the future as well, so I’ll definitely have a video for that too. Regarding the rear main seal, I do plan to drop the tranny at some point in the future as my garage is just too small currently, but I will definitely make a video when I get around to doing that. I’m glad you find my videos helpful, I’m very happy to give back to the GS/Lexus community in whatever way I can :)

[@theautochap]

Also I replaced the LBJs and door lock actuators not too long ago so I remember what I did pretty well, if you do get around to replacing them and need any assistance, feel free to shoot me an email at [e-mail] and I’ll be glad to help :)

[@the2jzchannel]

@@theautochap sweet! Thanks great job! I'm looking forward to see those future videos.

[@mrsnifflesal4020]

I am going to be doing this on a 1JZ GE engine everything looks similar apart from some things are in definitely places. Also there are not so many vacuum lines and the air intake pipe is a lot different

[@elboss6078]

I'm trying to do the 2jz on my 93 GS but it's totally different than all other 2jz I see online.. nobody has info on my specific engine.. I did my sparkplugs & now my car shakes...😢

[@NwakpaSunday-oi1tf]

I want to know how the plug wire

[@abc1234567892226]

This vedieo help thx. It looks scary but it's simple. By the way I think you miss 2 hoses behind the intake or close to underneath

[@theautochap]

I didn’t miss any hoses. I didn’t have to remove all the hoses because I’m not completely removing the throttle body only inverting it to access the spark plugs.

[@Steven-vz2gu]

Are those denso spark plugs the same as oem spark plugs?

[@jonathansalgado2067]

Yes denso and ngk are up when cross referencing them at a auto parts store

[@the.ghost.behind.u]

Denso ARE the oem spark plugs. Most oem Toyota parts are made by Denso, the coilpacks, spark plugs n wires are all Denso OEM. Furthermore the 98-00 GS300 actually require Denso Twin Platinum spark plugs, not Iridiums.

[@mohammednurul9380]

1:00 how cold the engine need to be, can it be modertly cooled like, 1 hour after drive? or does it need to morining start up cool?

[@theautochap]

Hi Mohammed, ideally it would be best to leave it to cool down overnight, because the engine and also all its hoses are very hot and take a long time to cool down. Since you’ll be removing a lot of hoses and the throttle body itself there’s a risk of burns. If you are in a real hurry, you could wait 5-6 hours but you’d be doing so at your own risk.
