HTML-код
- Опубликовано: 5 июл 2021
- 2015 Toyota Highlander spark plugs replacement. This was actually done in mid February 2021. This was done very carefully in order to make sure no electrical/plastic connections were broken or missed. That's why it took 4.5 hours over two days. Else it can be done in 2 hours in my opinion. Following are some technical details:
Model: 2015 Toyota Highlander AWD
Miles: 105000
Engine: 2GRFE
New Plugs: NGK Ruthenium
Old Plugs: DENSO Iridium
Gap: Not needed
Tools:
5/8 Spark Plug socket
5 mm Hex Bit
Long tipped pliers
10 mm socket
12 mm socket
Socket wrench; extension etc
Time required: 4.5 hours (very carefully; else it can be done in 2 hours perhaps)
Thanks.
I highly recommend it when you do a tune-up. Go ahead replace the valve cover gasket also.
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.
Thanks.
I am not a mechanic but developed some mechanical sense over some years. 😁✌️
Thanks for sharing this video. About to tackle this task myself. Great job on the explanation and the trial and errors. Thanks again brother.
Thank you. Just take your time. ✌️
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.
Thank you.
May be you are in CA. I would have changed my plugs earlier if it was easy.
@@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.
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!!!
Many thanks. I know what you mean and I made sure ahead of time that there was nothing around the intake. Accidents still happen. 😁
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. ✌️
@@whenopportunitycomes8718 your welcome but you did an excellent job so applaud your efforts. Keep up the great jobs.
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. 👍
LOL... you are just like me. Always get extra parts or bolts and nuts during reinstallation process.
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.
How many miles did your Highlander had when you change the spark plugs?
I forgot the exact mileage but it was around 101k.
Thanks for taking the learning hit and sharing. Toyota must hate their owners; I'm not looking forward to this.
Hehehe. Don't let it frustrate you. I analyzed a lot before starting the project. The correct tool - specially the hex bit was the key to less frustration. ✌️
Part numbers of the spark plugs?
Also, did you have any problems with the old plugs before changing to the new ones?
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.
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.
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.
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 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 changing 6 ignition coils is not a cheap proposition
@@condor5635 600 is not cheap but if your going to go through all this trouble then do it all at once.
@@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
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. 👍
i didnt see you check the plug gap. it may not be correct from the manufacturer.
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. 👍
I better changed it too.. no headaches for the next 5 years
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.
“Bro” I’m willing to bet the guy has alot more guts that you. A novice that was willing to learn and then proceed to tackle this difficult job.
