2nd Gen spark plugs

Does anyone have a good thread for replacing spark plugs on my 2nd gen? (location under the hood, best plugs to use; etc) I'm trying to learn and change them by myself for the first time



TIA

Edit: For a 6 cyl....

Not sure what you have.

 

My personal recommendation is start with a stone cold engine, your truck could have Denso or NGK plugs in it, or both (yeah they did that at the Factory) my preference is go back with NGK iridiums, take your time, and if possible, get someone to help you that has done this before. Plugs can be broken ( the porcelain ) when installing use anti seize,and a torque wrench to tighten them down. having the right tools plan on two hours.
the maintenance schedule sayes stock plugs are good to 100000 Mi. In my Humble opinion, Thats marketing Hype, replace them at 60000 and see what a difference it makes in throttle response, and smooth operation.
Good Luck

 

@TACOVRD mine is the 4cyl 2.7L, do you know if the locations vary between 4 & 6 cyl?

 

@Lucifer1 im at ~ 78k, so im practically on the verge of needing them im assuming

 

Is this thread helpful?

I replace mine every 15k miles

 

^^Good info^^. Always change spark plugs on a cold engine.

 

You’re joking right?

 

Nope, I get them for like 30 bucks a set and it takes me like 45 mins to do. So I figure screw it.

I know full well they can last 4 times that. But meh

 

@Bowen_
I would say you are right on time
Again
Good Luck!

 

@NYCT52
This is a textbook example of OCD, In my opinion you need Counseling.

 

Indeed. You should see how often I clean my air filter

 

@NYCTaco52
What? So how many air filters per spark plug change ?

 

Got a friend that gets me OEM filters for cheap. Replaced every 5k

 

I'll also clarify that I dont drive my taco as often as others. This year alone I've only put about 3500 miles on it

 

Do not use iridium plugs. Iridium plugs burn hotter. The aluminum heads on these engines are already very heat sensative. All you would be doing is adding heat and not really gaining anything. Save your money and engine and stick with normal plugs

 

@Lucifer1 This is one of those debates for the ages. If I was at home, I'd screen grab and insert photos but alas, I'm not so link's will have to do. Since we dont know if OP has a 4 or 6 cyl, I included both. Neither of these manuals tell the mechanic to use anti-seize of any type when reinstalling spark plugs. Denso doesn't recommend using anti-seize when installing their spark plug either (http://densoautoparts.com/spark-plugs-original-u-groove.aspx#undefined), at the bottom they state that they have a 'Precision machined-rolled threads to resist seizing ...' and none of Denso's manuals request that anti-seize compound be used when installing. I was in the same boat as you, heard it from a guy who heard it from an old school mechanic whose mantra was Anti-Seize the plugs. Something may have changed in the way engine blocks are made or in the way spark plugs are made but from now on, I am no longer using anti-seize on my plugs when I change them every 30k. My '12 4.0 didnt have anti-seize when I removed them at 30k but I didnt think anything of it as I beaded on a small dab of anti-seize when I plopped in the new plugs. Long story short, I am no longer using the stuff. Are you wrong for using it? Debateable. If you were to use the stuff, use the copper based stuff high temp over the graphite based anti-seize. Copper handles the heat better. But like I said above, I wouldn't use it. http://densoautoparts.com/spark-plug-installation Additionally, using anti-seize will make it easier to over-torque your plugs, so if you do use it, reduce your torque value by ~20%. The denso installation linke that I included states that 'IF you do use lubrication IE Anti-seize, to reduce torque by 1/3' but it doesn't state that it is required and again that seems to be a catchall for all vehicles utilizing Denso for their plugs. For reference (1GR-FE: http://www.customtacos.com/tech.old...f/06toyrm/06toypdf/06rmsrc/rm2006ta/02000.pdf, 2TR-FE: http://www.customtacos.com/tech.old...f/06toyrm/06toypdf/06rmsrc/rm2006ta/02100.pdf )

Another post stating about not using Anti-Seize.

This is another one of those debates, I'm all for following and using the correct plugs for your engine. That being said, 4 cylinder = Iridium, 6 cylinder = Copper. Instead of restating, I'll just quote from a previous post in this thread:

Bottom line, changing the spark plugs isn't as bad or hard as you might believe. As long as you have the proper tools, IE Spark plug socket and wrench extentions, you should be good to go OP. Another good rule to follow, use a bit of electrical tape and tape your socket to your extention just in case your socket comes off your extention and sits in your spark plug well. You'd need some mechnical fingers or a magnet to fish your socket out. You'll do fine OP, follow the links on how to change your spark plugs that others have posted above, they have pictures. Torque your plugs to 13 ft lbs, do not over tighten.

So if you change your plugs every 15k, that’s every 5 years. Doesn’t sound unreasonable.

 

Not sure where you are located but... why not have a maintenance / mod party? Get the local guys together I am sure there are a few that have that experience. Learn, meet & greet and have fun in the process
