NOTE: Iridium plugs *CAN* last up to 100,000 miles, but prolonged idling or oil consumption will wear them out faster! *In my opinion 80,000miles is a much safer time interval.* If you enjoyed the video, please give it a thumbs up 👍. Your support helps me create more content and is greatly appreciated . If you have any questions , comments , or suggestions for future videos, feel free to leave them below. I love hearing from you and look forward to your feedback !
@@QuangPham-hm7fm I wouldn't wait 'till 120K Miles, they could fail earlier than that depending on how the car was driven, especially if the car is driven in traffic frequently. Once the plugs wear out the catalytic converter will get damaged, so it's cheap insurance. Spark plugs don't cost a lot.
I'm at 90k miles. It sounds like you'd suggest I change the plugs now (better too early than wait until they go bad?). Is it critical to use OEM (Denso)?
Great video! Much better than some of the other videos on RU-vid. The torque specs is especially appreciated. Spark Plugs: 15 ftlbs Coilpacks: 7 ftlbs Oil Drain Plug: 25 ftlbs
Thank you so much for this information. I changed out my spark plugs this morning and it was SUPER EASY. I am sure this saved me TONS of money as well especially in this current inflated economy!!!! Thank you 🙏🏾
I'm shocked I haven't subbed to your channel. You are Definitely helpful 🤟🏻and I'm sure me and everyone else here appreciates you. Keep up the great work 🙏🏻.
If the spark plugs were recently changed at 100,000 miles and the coils resemble those in the video, they are likely in good condition. Spark plug coils generally do not require replacement as part of routine maintenance unless they are showing signs of wear such as cracks or corrosion, or if the engine is not running correctly.. Symptoms like rough idling, misfires, or an illuminated check engine light can indicate an ignition system problem. If there is ever an ignition problem, it should be fixed as soon as possible, to prevent engine damage. Spark plug coils typically do not need regular checks unless there are noticeable symptoms of engine performance issues, such as rough idling or misfires. Thanks for watching!
@@CleverFix thanks so much! Good to know. Saved $160 doing it myself and took little to no time thanks to you. Been about a year since I did it and have no issues whatsoever. Gotta love a Corolla.
@@618thrift Corolla is great! I changed my plugs a few thousand miles after this video, and it has been 2 years now. I didn't really notice any difference after changing them. Recently, It was running a little rough at idle, not perfectly steady, so I used a bottle of Redline Fuel System cleaner, and that fixed it. The engine runs like new again.
Thank you for such a great video! I loved how you laid out the exact tools needed at the beginning, and gave us the torque specifications! I bought one of those torque wrench adapters just like the one you are using, and I love it!
With the car off, there's no electricity flowing to those connectors, so it's ok. If your car has a remote starter you can disconnect the battery to make sure it can't start in case the button is pushed by mistake though. With even 1 plug disconnected it likely won't start though.
I would not wait 100k miles having in mind the cheap they are to change Same plugs Toyota in my country recommends change every 90000km ( abt 55000miles) After change the car engine is running much better ( personal opinion)
Thank you! Yes there are only four spark plugs. I have a separate video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pIhK3iIPQLk.html showing the best tools to use for removing the plugs, and there are links in the video description to all the tools.
This is what I just installed on my car: NGK LKAR7BIX-11S Iridium IX Spark Plug (93501 Iridium Ix), 4 Pack .. I don't think it's OEM exactly, because the plug didn't look 100% the same, but it's very close, and NGK is great. They're supposed to last 100K Miles, but 80K is a much better time to change them in my opinion, just to make sure. If they wear out, other things can get damaged like the catalytic converter.
I like the CVT, the old 4-speed didn't accelerate as nicely at all. This one is fast enough to merge on the highway easily, especially with the sport button on.
@@CleverFix the description doesn’t help to an extent as some 9/16” spark plug socket run short and other 14mm sockets are too thick to fit in the spark plug well. The brand you use would help, but it’s alright.
@@xricelover123 The socket I linked in the description should fit because it's intended for spark plugs. Don't just use any deep 14mm or 9/16, it has to be intended for spark plugs, which means they will have made sure the walls are thin. 14mm is technically the correct size, mine said 14mm OR 9/16 on the label, it's a local brand here from a store Princess Auto which you probably won't have in your area.
It likely that the wall of the socket is too thick, and doesn't fit between the plug and wall. It has to be a 9/16 spark plug socket, just any 9/16 socket will be too thick.
It's called a digital torque adapter. See some here: www.amazon.com/s?k=digital+torque+adapter&ref=nb_sb_noss_2 You can also buy the entire wrench with the digital read out built in, but they're more expensive, about double the price. I bought that for around $50 which is not too bad.
It's Dielectric Tune-up Grease, I added a link to it in the video description. It makes a water-tight seal, and ensures the rubber doesn't stick to the plug. I also use it on the battery terminals to prevent corrosion and it works great. Thanks for the question. 👍
Are you first owner? Probably the previous owner just installed a different kind, there are all sorts of plugs, it doesn't mean there's anything wrong. Not sure what you need help with.
Hi, I have an updated tool list here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pIhK3iIPQLk.html I made that video once I figured out an easier way to do it. There is a link for the extension there.
You can find it here: amzn.to/2HCtrYx It's kind of a no brand, I've seen the box it comes with branded under different brands. There are other adapters like this also, this has worked very good for me, but be careful not to turn the plastic part around the metal part, it allows some spinning if forced and will break the wires, I opened mine to fix it, and I never spun the plastic part after that and it has been good. It's basically a metal 1/2" extension inside with some wires coming out of it that are connected to the plastic casing with the LCD.
We are using the 9/16 but it appears to not click onto the spark plugs. As if they are larger than the socket. If we try a larger socket, it does not fit into the tunnel. Any idea how to help?
You need a spark plug socket to click onto the socket and pull it out after loosening.. they tend to be magnetic or some have a rubber thingy inside to “grab” it. A regular 9/16 socket will just slide in and out over the spark plug..
Good way to break off the piece of platinum at the very top tip. They use a special metal so it stays that way those plugs will run 100,000 miles but don’t be testing them and checking them just leave them in and run them.
They're iridium, and they ran fine for thousands of miles after I re-installed them. Care must be taken to avoid placing pressure on the center electrode when checking gap,.. in the video, I am placing very gentle pressure.
I have started this job at least 5 times and failed every time lol. I have purchased at least 6 different sockets for the spark plug. The plugs I already had were not deep enough for the spark plug( the end of the plug would stick through the square end that the ratchet should attach into) I bought one long enough but it was too wide to fit into the spark plug well. I bought I thinner version but was hitting something down in the well and would not make it around the spark plug. It seems like I need a super thin (exterior diameter) socket to pull the plug out. Has anyone had this issue?!
Check the video description for a link to a thin wall socket. It has to be a "spark plug" socket, it should be labelled as specifically for spark plugs, otherwise it won't work. Yes I had this problem too when I first tried to use a normal socket.
Post a video with the sound. VERY unlikely spark plugs would have anything to do with an unusual sound. These plugs are good for 100,000 miles. How many miles you have?
@@CleverFix yes I did is fixed in fact it wasn't the spark plug it was actually the motor amount was making the noise and please let people know about four areas of the motor mountain mania replace if it starts making the noise
NGK 92274 is made with Ruthenium, supposed to be even better! But OEM Denso spark plug is very good quality too. See this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4GbUX52Ltu8.html
@@CleverFix I'm changing mine today with Denso from dealer but I'll keep this in mind and change them sometimes next year to see any improvements. So far your video on the CVT fluid (drain and fill) has done a remarkable job on my car. Shifts smoother and it runs pretty well when acceleration is needed. Although... I want to drain and fill with new fluid at some point. I've used 10 or about 13 quarts of CVT fluid. Thanks! And keep making awesome videos!
@@castilloabraham90 Awesome. Yes I noticed the improvement as well with just one change of about 2 quarts. With 10+ that's amazing.. I probably should've done more, I changed only 4 quarts since I bought the car because I didn't want to spend too much $$$, but you got me thinking now!
@@HassonyAl3raqi engineswork.com/best-spark-plugs/toyota-corolla.html 1.11mm I advise using a feeler gauge from Canadian Tire that is in inches!.. They're cheap. www.canadiantire.ca/en/pdp/mastercraft-26-leaf-feeler-gauge-3-in-0581649p.0581649.html which has markings in Inches!
DO NOT make the mistake I did and use a regular size 14mm socket ( I didn’t know) ended up getting stuck stripping the plug threads chipping the piston and messing up the wall of it, now I have to replace my entire motor!! 4 thousand dollars, Cause of a simple mistake. Thanks
Sorry to hear that , just wondering though how a regular 14mm socket fit inside the hole though?. Normally a 14mm regular socket will simply not fit in, it doesn't do any damage. The plug threads strip only if too much pressure is put on ... were you using a torque wrench? Also, check out www.car-part.com/ you can find a used motor for a fair price from a wrecker, 4000 sounds like too much to me.
@@CleverFix yeah it was a different sized 14mm, I’m not exactly sure how it got stuck, it got pushed down into the spark plug, had to break the destroy the old spark plug to get it out, when I put a new plug in it messed up the threads in it causing me to not be able to tighten the new plug all the way. Yeah the motor itself is 1700, but with labor and all other parts I’m in basically 4k
@@brendanbasden2442 How did the piston and wall get damaged though? The plug couldn't be installed, so that means engine can't start?.. A stripped plug thread is repairable and is much easier than a new engine.
@@CleverFix when I put the new plug on I wanted to see if it was all the way on or if the threads were messed up, so I started it, it then did something with the piston getting chipped. I have photos. My buddy originally was fixing the threads, but then found that
@@brendanbasden2442 Ok wow... I checked a more popular video, and this guy uses a normal socket: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rt020ue1wpI.html and still seems to work ok for him. Maybe when you were unscrewing the old plug, the engine was warm or hot?.. that may explain why the socket got stuck. I found some 2ZRFE engines for as low as $1000US on car-part.. also wreckers usually let go of prices.. My friend just gives them an offer, and a lot of times they take it.. so if they have listed $1700, they would very likely take an offer for $1500. Good luck fixing it.
