I'm leaning over the engine of my 2012 highlander 2GRFE, watching this in order to avoid the task at hand😂. One tip: When removing the 3 plugs on #1,3,& 5, a 6" wobbly extension on your 5/8" s.p.socket helps to minimize the struggle with the harness. Cheers!
So just some recommendations,,,,, the removal of the coolant throttle body hoses were not needed. You would remove throttle body and replace the gasket upon installation the other gskt to replace are the intake orange surge tank rubber gskt. Wouldn’t recommend reusing, #2nd if you purchase oem iridium spark plugs you do not put any anti seize on threads. The metal on threads are special will not seize in bolt holes. And finally great job with everything else. I would also disconnect the battery. I worked at Lexus toyota 15 yrs just interjecting other suggestions if doing this job ,,,,,, but great job
Thanks for taking time to watch the video. I am not a professional but like to do things with proper info as much as possible. Appreciate all the valuable knowledge you just shared. ✌️
Very nice how you learned by doing the job. You systematically went through and assessed along the way. Great video! Not sure I'd have the patience or guts to do this on my own as I'm a total noob.
Nicely done. I have a 15 Highlander as well. Tranny fluid is first, then plugs. Tranny fluid is also a PIA. Scary though watching you with those open intake holes uncovered. I was cringing the whole time but you eventually put the towel over them -- sheeew. Anyway, very well done!!!
Good job. You just increased the life of your Hilander. Thanks for the tips. I replaced the spark plugs in my 2017 Hilander at 60 000 miles to comply with emissions regulations. I also change the engine oil every 5 000 miles because the 10 000- mile intervals have been destroying engines.
@@whenopportunitycomes8718 I hear you. The spark plugs in all the V6 Toyotas 2000 and newer are very difficult or tedious to replace and requires adequate tools. I will be replacing them at least every five years because I want to keep it for many years.
Except for not checking the spark plug gap, nice job. Never skip the gap. I just had to redue a spark plug job on my lexus because I ASSUMED the factory gap was correct. I should have known better, my bad.
There were pre-gapped and the tips looks very solid. That's why I didn't want to touch them. So far after 25k driving - never felt any difference in driving or gas mileage. However - it definitely doesn't hurt to check the gaps. 👍
After 167.590 thousands miles l replacement my toyota highlander spark plugs but in the end l still try tu found where 2 screws should belong l saves for the nest plugs replacement not choice Who whant to remove all back that are crazy thanks to the new toyota engineers
Two screws or bolts? It's hard to tell without looking. There are two 12mm bolts - one holds a bracket before the air intake plenum and another below the throttle body.
I have heard that when you buy these used,most of the time you should check the spark plugs and timing chain precisely because nobody likes to take apart this engine.
Makes sense. However - you can tell a lot looking at the exhaust fume and running performance. Other than that - there are some people who really don't take care of their vehicle at all.
@@MP33dave you have good eyes. 👍 I am not a mechanic but I try to do this kind of work by studying a bit and then paying lots of attention to details - so far the results have been good.
I don't have that info now but I can tell you this - I ordered them from rockauto.com. see whatever number they show for your exact model and trim - it's all good. 👍. No I did not have any problems at all but felt the sharpness after installing the new ones. After 100k it was due for that change anyway.
Thanks for this video. The thieving Toyota dealership quoted $600 to do this. How much did you pay for the new plugs please? I've gotta to this change myself as a point of principle. $600 is pure out and out highway robbery.
I would recommend changing the gaskets, ignition coils and spark plugs all in one shot. That way you can save the hassle of doing this again until the next 100,000 miles.
@@ssjrichovr9k33 - I have 240K one one Highlander (did this spark plug job on it) and 90K on another. Never changed an ignition coil before. They are pretty resilient I think
Thanks for your question. It was already gapped 0.043" and in some sites it said to gap 0.044 - so I did not do anything. I could have made things worse by trying to manually gap them. 👍
Why not replace the back coils also while you were back there replacing the plugs? I think they are like $40 each. They do fail and what a pain to have to pay a mechanic to replace one.
I would have but they were looking super good. Now that I know the process - it won't be that bad if I need to replace any. When that time comes I will change all the coils. 👍

LOL... you are just like me. Always get extra parts or bolts and nuts during reinstallation process.

How many miles did your Highlander had when you change the spark plugs?
I forgot the exact mileage but it was around 101k.
You need to cover the intake manifold open ports with a towel - if something falls in one of those ports - you're screwed.
@@MP33dave I did actually. Maybe the vid showed the final moments
@@whenopportunitycomes8718 True - you did but at first you had me really nervous lol
@@MP33dave you have good eyes. 👍 I am not a mechanic but I try to do this kind of work by studying a bit and then paying lots of attention to details - so far the results have been good.
Part numbers of the spark plugs?
Also, did you have any problems with the old plugs before changing to the new ones?

You should replace intake gasket
I did put new Air intake plenum gasket. Original one looked just perfect but I still decided to put a new one. 👍

Hello Tim. Thanks for watching. I think plugs were 75 and then I had to buy a set of tools. So the job was done for $94. ✌️

I better changed it too.. no headaches for the next 5 years
With 6 coils from the dealer costing $1,070 and afm coils an unacceptable substitute, there's no justification for changing coils preemptively.
Toyota is dumb for this design this was one of the hardest spark plug jobs I ever had to do, I gave up and took this to the mechanic
Totally agree.
The same as ford escape.
Bro you don’t know the names and size of what you doing
😂 but he figured it out. I like that he was not afraid, even though he had little experience. In his situation it turned out ok.
