Mitsubishi Endeavor Spark Plug Change or Cleaning

This video was made to show to the viewer how I cleaned the right bank Spark Plugs on a Mitsubishi Endeavor with a 6G75 engine (V6 3.8L ci 3797cc MFI GAS SOHC).
The engine may be similar with:
2003-Present Mitsubishi Pajero (aka Montero / Shogun)
2005-2011 Mitsubishi Endeavor
2004-2009 Mitsubishi Galant
2005-2008 Mitsubishi 380
2006-2012 Mitsubishi Eclipse
I’m not a Mechanic, only a D.I.Y.’er, so sorry, I cannot answer any of your technical questions. But, ‘If you’ve seen one, then you can definitely do one …’ and the video will speak for itself.
Some scenes in the video were re-arranged to show or emphasize a procedure that I should have followed to make my job easier and faster. A word of caution!!! Some parts of the video are shaky and may cause dizziness to some people.

Thank you, help me fix same issue in my endeavor, the best tutorial to replace endeavor's spark plugs

[@bluenetmarketing]

This is a great video, but there is no way on God's green Earth that I am going to even touch this job.

[@nanolathe1193]

same. when i saw the tools needed i was already out

[@reapersofeden1]

​@@nanolathe1193what you mean you just need a socket wrenches and a pair of pillars and lots of liquor for the stress lol 😂

[@nanolathe1193]

i thought you just had to pop the hood, take off the cover to the engine block and your spark plugs are all right there. pretty crazy its this long of a process just for spark plugs but obviously things are different these days.

[@angryraven]

Just did this all step by step thank you so much!!!

[@ADUSEI6111]

Thank You very much for this, it really helped me out alot

[@NINrod_M]

Well...I’m getting a mechanic. Good video though. Thanks for making it.

[@johnd942]

In a word; excellent!

[@sonjah9273]

any video on replacing the thermostat?

[@torraplehcim5987]

Thanks, most helpful. Would like to hear from the one's responsible for such a design. So much work just to reach the back spark plugs. By the way, in my case the Plenum bolts are 12mm and not 10mm. A+

[@panchitoramirez9276]

Damn all that work for spark plugs I feel by for my nephew he just bought this same model of suv.

[@Jackthesmilingblack]

On a Mitsubishi Pajero iO, the stem that goes between the spark plug and the transformer, suffers an electrical short circuit at the base at around 100,000 to 120,000 km. Not a big deal to find and change. You can buy the stem separately, and remove the failed part from the transformer head. "use a 10mm socket and a 2-inch extension wrench." The usual USCS/metric mishmash. No wonder the Hubble telescope lens had to be replaced!

[@reggiej8403]

Great job, @Nunki Rider. Re the assembled 26 inch extension which you used to reach the driver side rear bolt, may I know the specific lengths of the extension bars that you used. Thanks.

[@nunkirider8738]

+Reggie J - Two 10 inches and one 6 inches - 3/8 extension bars connected in series.

[@reggiej8403]

@@nunkirider8738, thank you. Appreciate it.

[@demetriusharris2169]

ohh yea thanks you make it look so easy

[@xxcloudyxx4819]

Do you happen to know if this model has an Idle Air Control Valve?

[@grasshopper5353]

Is there another name for the throttle body "stay" I can't find replacement.

[@nunkirider8738]

@GrassHopper- It is a “bracket” that holds the throttle body in place on the Mitsu Endeavor. Only the junk yards like ‘U Pull R Parts’ sell this thing. OEM did not even bother to list the part number.

[@johnd942]

Some intelligent music too! :))

[@richardpolesnak6512]

sir, do you have a video or pdf file on installing a mitsibishi/endenvaor/ 2004/ part# 4455A044/ power steering cooler tube. thank for your time and info.

[@nunkirider8738]

@richard polesnak - Sorry I have no video of it, however, go to my channel and watch the video “Armor of Glory”. Read my reply to Den Kooper and hopefully you will see there what you need to know… thanks for watching my video…:)

[@kalacooper7096]

My coil packs keep going out plus the transmission hesitates a little bit when shifts.. do you think it's a transmission sensor problem that's overloading the coil packs?

[@kalacooper7096]

And the shift all the way to highest gear when I'm cruising at 35 mph.. please help.. thank you

[@osvaldocortazar1343]

great job¡¡¡¡ but and the other 3 sparks plugs ?

[@nunkirider8738]

+Osvaldo Cortazar - Thank you for watching the video. The other 3 spark plugs on the left side of the engine are very easy to access and the procedure is very similar if you watch this video from 6:03 to 9:19.

[@osvaldocortazar1343]

Thank you.. Will try

[@allencastillo5887]

I did everything in the video but when I start the engine it doesn’t turn over and white smoke comes out of it ?? I also did loose quite a bit of coolant could that be the problem

[@nunkirider8738]

@ allen castillo - no coolant should be lost in this procedure, refill if the coolant level is low. Check the 2 coolant hose on the firewall side of the throttle body for its integrity. The white smoke that will bellows out the tail pipe on starting the engine is usually due to engine oil that leaked inside the spark plug well (which is usually due to a leaking spark plug well gasket) and when the spark plugs are removed, this drained into the combustion chamber and was burned but this smoke should go away after a few minutes of running the engine. May I ask if you removed the throttle body from the plenum or loosen its bolt or cleaned the throttle plate? Is there a check engine light in the dash? Recheck all your electrical and hose connections.

[@allencastillo5887]

I removed the hoses connected to the throttle body. And I also replaced the plenum gasket but did not remove the throttle body at all

[@allencastillo5887]

And I only removed the two bolts that were attached to the throttlebody

[@allencastillo5887]

I didn’t gap the sparks plugs but I’m thinking of taking the manifold apart again and redoing the spark plugs and checking the plenum gasket again.

[@howardsternssmicrophone9332]

This is utter insanity just to change some spark plugs. Why didn't they over engineer it even further so you have to take the whole engine out to change the spark plugs?

[@ВасилийИванов-я8п]

Спасибо друг! Привет из России! Очень информативно. Молодец🤝

[@nunkirider8738]

@ Василий Иванов - Спасибо, что уделили время просмотру видео, мой друг. Удачи и сил вам!

[@gdk229]

Why did Mitsubishi advice you not to gap the spark plugs?

[@nunkirider8738]

The reason... I don’t know. You can read this on the owner’s manual of 2004 Mits Endeavor on the vehicle care and maintenance section 7-28 and I’ll quote... “ Do not reuse them by cleaning or regapping. Change them at the mileage listed......”

[@Dragonborn__]

Probably because of the risk of damaging the electrode if improperly gapped. Also, if you're going to spend the time removing the intake manifold why not spend $30-$50 and just replace the spark plugs. I would advice cleaning and gapping old spark plugs.

[@HardMyD]

Got so many questions but where literally inside the engine bay to get the back bolts?

[@nunkirider8738]

+HardMyD - You can’t really see the rear stay bolts from the top of the engine bay. You have to literally reach in and palpate for it and unbolt it blindly. At 4:42 - 4:43 you can see my fingers pointing towards the firewall and then reaching down towards the back of the plenum. This is the approximate area where the passenger side stay bolt is located. You can see the mount of the passenger side stay bolt clearly at 6:15, it is behind the left most ignition coil while the driver side stay bolt mount is behind the right most ignition coil. 6:39 has a better view of the passenger side stay bolt mount while the driver stay bolt mount is only partially seen. The driver side stay bolt can be seen from below the engine bay and it is easier to remove it from there using a socket in a swivel and extension wrench.

[@HardMyD]

Thanks alot nice and clear, was wandering if you can tell me what type of power steering fluid i need too, I dont have the owners manual 😡

[@nunkirider8738]

The owners manual says 'Genuine Mitsubishi Power Steering Fluid' and has a capacity of 1.2 L (1.3 qt)

[@howardsternssmicrophone9332]

Cars of today are so poorly designed, and over engineered. They do that on purpose so you can't fix it yourself. The big car manufacturers cut a deal with the Mechanics to make cars next to impossible to work on unless you take them to a "professional". I could go on, and on...

[@markpunzalan7964]

Hahaha pahirap baklas lahat bago mabaklas sparkplug

[@howardsternssmicrophone9332]

THis angers me, not because I can't do it, but because you have to jump through so many hoops to change some spark plugs that sit on top of the engine. I hope whoever designed this vehicle moved on to something else in life, and was permanently banned from trying to design anything else.

[@isaiahtowers1865]

Yeah after my endeavor started having problems it’s so apparent that either the designers of the vehicle purposely made it impossible to do a simple fix on your car or they did not know what they were doing, even just replacing a headlight was the most difficult thing on the planet. This car WAS amazing, had it all summer in the Tetons driving all the time, as soon as one issue began the whole car decided it was over with. I hate whoever designed this vehicle, they even made it so that you can’t put the radio system back in after it’s removed, the clips won’t go back in.

[@thewonderfulworldofanonymo7650]

At least he was lucky he didn't have to remove a radiator, I had to rotate my motor forward enough in my Gran Prix to access the rear three plugs. lol.

[@codenebula4818]

Dude you are literally the most helpful person ever almost no one makes any videos for maintenance on the endeavor bigget life saver🙏🫶
