THANK YOU for describing all the tools needed, and mentioning stuff like "threaded side down" for total newbs and those who forget what seems like super-obvious stuff (which is me on both counts).

[@KJs_Garage]

I really do the best I can to make my tutorials as detailed as possible, I'm glad it was helpful!!

[@dallasbeus2117]

The flexible socket adapter is important, I will use it for sparkplugs and other similar situations. Thanks for the video, God bless!

[@danstonge91]

Couple things missing from this video. First, I would apply dielectric grease to the spark plug boot/coil pack and second, I would apply dielectric grease to connector for coil pack so it makes it easier to remove next time. Also, I wouldn't drop the spark plug down the hole, that may affect the gap and may need to be regapped. Use a piece of fuel line or hose to get spark plug started by hand

[@wwmilanl]

Also I will sugest put some anti seize grease to the spark plug thread

[@isaiahborba8927]

How much to the boot and where

[@eliterry3785]

This video was the ticket. MAGNET is essential! 👍🏻 thank you!!

[@saeen6286]

I have some issues with dropping the plug. Can we use the plug boot to hold the plug , insert in the opening and give some initial turn until it's seated ? Next step will be removing the boot and tighten it to spec. OP: I like your video. Very detailed. 👍

[@Oregon-Ducks]

Don’t drop it in. Use a hose or the boot to seat it

im late but you can use a telescopic magnetic stick tool to drop the plugs, works great

[@doruapostolul3029]

Dropping the spark plug that's NOT good idea you can put it inside with the coil and turn until it's ok. I just checked my spark plugs at 71.000 km + and it's like new I was happy to see that.

[@willypedernales4213]

Dont't drop the sparkplug. Hold it with a plastic tubing or something to land them softly. The reason for this is to NOT to change the tip calibration of the sparkplug. otherwise, they need to be recibrated by hand.

[@MelodylaneLou]

Regapped? You can drop these on the floor not enough force to change the gap.

[@beeezybone]

I’ve changed my spark plug on 69k miles on my 2014 corolla and it was even more dirty than the 100k spark plug you changed. Any thoughts why?

[@KJs_Garage]

Quality of gas could be a factor, or your car might have an oil consumption issue? Disconnect the intake at the throttle body and look at how dirty it is. If there's excess oil there, you have a blow-by problem. If it's clean, then just make sure you're using high quality gasoline, and I don't mean 93 octane, I mean just a good brand. Also bear in mind that I run my car for 8 hours as a time, which is healthier for motors overall. If you only do short trips, you will see more wear on parts because it spends more time heating up to operating temperature, where the most damage is done to a motor

[@bigchainring1977]

@@KJs_Garage so you're saying the process of heating up and cooling down is what does the damage to the engine parts, not when it's running at temperature and at higher speed?

[@frederickneal4781]

You guys making these videos should use a piece of vacuum hose on the spark plug to guide it back in to greatly reduce the risk of cross threading.

[@KJs_Garage]

That's a great suggestion! I'm going to be doing another spark plug job here soon so I'll bear that in mind

[@daniellelocklear2979]

Does the BOSCH Double Iridium spark plugs work with the 2NZFE 1.3L engine ?

[@JuanLopez-gh1rb]

Are those Bosch irridium plugs have any driveability issues ? Are they run good in your Corolla

[@KJs_Garage]

230,000 miles and I've not run into any problems

[@brblum]

I'd recommend using the OEM Denso spark plugs. While others can work, this puts the odds more in your favor. Even my mechanic, when I told him I was changing the plugs on my Camry, told me that Toyotas can be picky and to only use the OEM Denso plugs specified in the owners manual.

[@JuanLopez-gh1rb]

@@brblum yea I bought some....they run great! So no issues with the Bosch iridium plugs....they only said to change them every 75k to get max performance out of the plugs ...they were 7.99$ a plug versus 21$ a plug...so they fit my budget just fine

[@KJs_Garage]

All I know is that I have a 2017 Corolla and all models and all trims from 2009 to 2019 with the 1.8 liter motor all use the same plugs

[@Turco949]

Always degrease and wipe the dirt/grime off around any opening that leads to engine, tranny, etc. Also, I would not drop the spark plug in like that if the drop is deep like that, if it lands off center, the impact could change the gap and even damage the plug.

[@TheEnd-vn9rb]

I am using a 9/16 deep well spark plug socket, and I cannot grip the spark plug. The socket just free spins as I try to get it to fall into the spark plug. Help!?

[@KJs_Garage]

Check the sockets you're using with the new spark plugs and ensure that they are long enough to reach. Then try different size sockets until one fits and you can pull them out

[@JirmaVerse]

I’m using denso iridium spark plugs that I purchased from the dealer. I’m assuming that different spark plug manufacturers use different sizes for their spark plugs. 9/16 didn’t work for me either. I’m using a 14 mm.

[@jidmoonh]

Either socket should work since they are very close in size - less than 1/64" difference. However, I found that some 9/16" can be less thin-walled than others, so the 14mm is preferred. Thicker-walled sockets will bind on the spark-plug-tube walls and resist going deeper and may even get stuck in the tube - this tube seems to have a slight taper. Not having a 14mm deep-socket, I ended up grinding off ~0.5mm from the outside wall of one of my 9/16" sockets, about 1/2" up from the bottom. It solved the issue, and saved me the long drive to town and back!!

[@ricowork]

All my other SUVs and small cars use 5/8 socket. Why does Corolla have to be 9/16?

[@LEFT4eV3r]

Can you tell me the what was the ratchet extension???

[@KJs_Garage]

They're called universal joints, or u-joints

[@thekaydonsouth]

Can use a wobble extension also

[@Drew1734]

I did this verbatim being extra careful when re threading the new plugs in, but My check engine light is now on. Has persisted through multiple ignition cycles. Any reason why this should happen? Is there some lubricant I am missing or something? Should I just try to reset the code and see if it comes back?

[@KJs_Garage]

Make sure that all of your plugs are properly connected, maybe disconnect and reconnect the battery, if the problem persists, take it to AutoZone or advance Auto or something and have the code read, and then proceed from there

[@ZPX945]

is the new plug pre gaped or do I need to check it and gap it self?

[@KJs_Garage]

Most plugs come pre-gapped already, but it's always good practice to double-check

[@fanofbama14]

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?!

you need to put that anti-seize grease on the threads of the new plugs so when you change them next time they will be easy to get out

[@saeen6286]

I depends, some manufacturers do not recommend to use anti seize. It might over tight the plugs.

[@rich6828]

@@saeen6286 agreed. You have to reduce torque by 10% or so. I have stripped out aluminum heads that way, torqueing it after applying anti-seize

"Drop the spark plug into the hole." The horror, the horror. Rather, insert the new spark plug into a piece of 1/4 inch fuel line and gently lower it into the spark plug hole. Next, rotate the fuel line with the attached spark plug clockwise to thread the plug into the hole. Or better yet, purchase a magnetic spark plug socket.

My socket us stuck inside

[@BBMetalKing]

Ahhhhh....So a 2009 Corolla takes a 9/16 socket and NOT a 5/8. My mistake. Good to know. I also recommend putting anti-seize lubricant on the spark plug threads AND to use di-electric grease on the ignition coil boot AND it doesn't hurt to put di-electric grease on the engine wire plug connector to the coil pack. OH...another thing....if you feel the need to torque your spark plugs, it is recommended to tighten to 11 foot-pounds WITH anti-seize lubricant.

[@charlieellis8777]

do you put the de electric grease in the wire plug or just around the outside

[@BBMetalKing]

@@charlieellis8777 I put di electric grease inside the wire plug. To do that, I use a Q-Tip.

So you don't use any dielectric grease?

It's a good idea. I totally recommend it. In the coil boot and on top of the pack connecting to the engine wire harness.

9/16? I've been using 5/8 for years! No wonder my shit won't fit!

Get a 14mm socket..... 9/16 is roughly 14.30mm. While yes you can make this work you also risk stripping a vital engine component. This is a japanese car lol and yes I'm being that guy, don't give a sh*t.
