How to Replace Lexus IS250 Spark Plugs POV

A quick step by step guide on replacing spark plugs on a Lexus IS250.
Torque Specs:
Spark plugs 18ft/lb
Ignition Coils 7ft/lb
Intake Manifold 5mm Hex bolts 13ft/lb 10mm Nuts 12ft/lb

A lot of these IS250 (2nd gen) spark plug videos fail to mention there is a connector/harness that's usually clipped into the back of the intake manifold (really hard to see if not impossible - you have to go through removing all the bolts and other connectors first and lift the intake manifold before you see it). You have to unclip that harness to pull the intake manifold off. Failure to mention this sometimes causes people to yank off the intake manifold thinking it's "free," but they could be damaging that connector. FYI

I should make a video of that.

How much is to paid some one to do it? $300 bucks , changing the spark plugs on this car would take forever, I was thinking to buy one, after seeing this video, great video, NoW I'm not gonna buy A lexus IS 250 or 350 to much freaking time to do the job for just to change 6 spark plugs I give up !!!

[@lIlIlIlIlIIIlIllIIllIII]

@@tonydominguez2906 I think they'd charge something like $400-$500 because they can (mostly labor and they know it's going to be time consuming if you aren't used to all the little tricky things). If I had to do this job myself again it'd probably take me about 2 to 2.5 hours and $80 for spark plugs (assuming I have the proper hand tools and hand tools are all you need anyways). The first time around it took 4+ hours and I had to diagnose an engine code which was from ripping out that harness I mentioned. Cost an extra $30-$40 to get a new harness. Though, in $ terms, I still did it for cheaper than a mechanic would and learned more about the 2012 IS250. P.S. There's another tricky part involving the northmost bolt close to the firewall -- I really needed a U-joint type socket adapter thing to be able to get proper access on it. Not sure if this video was the one that mentions that cause I made this comment a while ago. Hope it helps

@@lIlIlIlIlIIIlIllIIllIIINoted, thanks for that info, Im honestly not sure if I have the balls to do it myself in the driveway. Lots of stuff to remember & put back. Any chance you know of some sort of write-up for this?

[@lIlIlIlIlIIIlIllIIllIII]

@@ph_mp4 Unfortunately I don't but most of the videos are pretty good. Just keep in mind what I mentioned about where you have to disconnect the harness after removing the bolt at the back. Which, by the way, is an annoying bolt and from my experience the hardest/most annoying bolt to remove. You might need a universal joint/adapter that gyrates in order to get it out.

Very informative! Thank you!

This is a great video, it is to much worked time spend just to change 6 spark plugs on a vehicle, I was thinking buy Me a Used lexus IS 250, 330,350 , after seeing this great video how to do it right I'm not gonna buy Lexus,and you have to do it again closed to 100,00 nope tu much work,how do you know if you take toyota dealer you paid them one arm and half of your leg, how do you really know if they really did it , like this guy is showing on his video, that why you have to do it yourself, but for me it is tu much work, I gave up and I'm not buying a lexus , I gonna stick with Old Camrys very simple to work It I'll I got one myself it is 2003 toyota Camry with only 65,000 miles on it , it only takes 15 minutes to change 4 spark plugs, if you know what you doing and it cost me 15 minutes of my time,,, great video thanks for sharing

[@FircxTM]

I stripped 2 out of the 3 allen screws in the intake manifold and tried multiple solutions to take them out, such as using an allen strip screw kit, vice grips, hammering the 9mm, and jb welding another screw to it. Is there any other recommendations you have besides the one mention in the video

[@angrymechanic5529]

At that point your only other option would be to drill out the head of the bolts and extract whats left after pulling out the intake manifold.

[@mikealizor1259]

Thanks for this video. Do you have video on knock sensor replacement on the 2007 is250 Lexus or its location. Your help will be appreciated.

[@joecox9958]

many thanks! very nice!

[@hotchoi6613]

Man toyota should be easy to work on what happened?? Lexus wants to make more money on service fees

[@robertmartinez167]

What year is the car

[@crazyprayingmantis5596]

If I unhook the wiring harness is it safe to manually open the butterfly in the throttle body to clean it?

[@zulqarnain401]

yes

[@draggoneperformancetv1198]

Well done

[@yansselllb123]

Do you have to change the manifold seal?

[@angrymechanic5529]

It would be a good idea to since you are there already but I have reused them without issues.

[@yansselllb123]

@@angrymechanic5529 thank you am doing it now as we speak, I think am going to reuse them for now

[@ashishpatel350]

Technically you are supposed to change them because they are crush seals but you can reuse them if you have an intake leak then you'll have to change them. Make sure you clean the matting surface and gaskets if you re use them.

[@vannarasong]

no wonder why the dealership want's $1k 🤣🤣

[@leonidas9969]

Kills me watching these videos doing everything by hand used to being flat rate at ford and just easier

[@EastCoastReefer]

Too much shaking. Unbearable to watch.

[@JonniArmani]

This is a intricate job level 8 on a 1-10

[@AtomicBlueJay]

That fucking bolt in the back is the worst design ever

[@blastmink1352]

should always wear gloves when working on a motor. plugs must be tighten to 13 lb ft or 20 Nm on a aluminum block but not random as you show

[@angrymechanic5529]

All torque specs in the description were taken from Alldata repair. You are right I do not advise the beginner to tighten the plugs without a torque wrench, I have been doing this for 15 years so I have a good feel. Gloves are good to have too 😀

[@libertyforall5764]

Sorry, but I wish you had a camera man because I can't stand the constant moving of the camera...but thanks for the video though.

[@fernandovasquez1912]

Thank you so much

[@jerryl10000]

how much did you charge for this job?

[@angrymechanic5529]

Book time is 2.9 hours, at our labor rate of $90/hr it would work out to $261 for labor.

[@SkettiOnTheBeat]

Where Are You Located ??

[@sandyasmr5105]

NGK SPARK PLUG IS THE BEST FOR THIS CAR MY FATHER HAS 20+ YEARS IN BEING W MECHANIC, JUST KNOW THAT THEY ARE AROUND 9-10$ EACH! BUT WORTH IT THEY LAST LONGER THEN THE CHEAP ONES PLUS YOU GET A BIT MORE POWER AS WELL

[@sadikhagar677]
