Finally a channel for a Mitsubishi 3.0 engine.

You have the patience of an angel......I used to be a mechanic but threw my tools around after I completed my apprenticeship and quit....I admire your patience and dexterity. You are a champion !! i'd never attempt such a job just to replace the spark plugs. Mitsubishi should be ashamed of themselves for designing such an engine and not thinking of the poor mechanic.

I have a 2003 mitsubishi eclipse and I wish this dude was my mechanic..

I own a 03 Mitsubishi Eclipse GTS and was feeling cocky like I could do this by myself just to change the spark plugs. After watching this video I re-evaluated and decided to get the wires,a timing belt/water pump kit,the valve cover gasket set and the distributer cap aswell. Costs more money in parts but this hassle looks well worth doing it all at once 😂😂 thank you

First Off Great Video! I did a couple things differently though to make it easier on me. 1) the black support that runs from one side strut mount to the other just at the firewall 4 nuts and two bolts and it makes it sooo much easier to get those rear manifold bolts. 2) I just COULD NOT get the coolant hose off the throttle body so I just disconnected the throttle body from the manifold 4 bolts EASY! Thanks again for the video!!

this video was very helpful. because now I know if you have a 2002-2005 Mitsubishi Eclipse GT it is basically a royal pain in the ass to change the spark plugs. and in my case I also learned I need a new valve cover gasket. thank you lol

it'd suck to spending about 400 dollars on this ! So Diy for less than 200, make sure you have proper tools , metric. few adapters and extension. the worst will be the exhaust pipe . dont belive you need to undo any coolant hoses i didnt , also remove your motor support tower bar gives you more space , everything will only go bk on one way. i do suggest buying quality plugs an wires or oem. buy valve cover gasket kit just incase you find oil in the wells you can always return it unless you wanna do this job again by only wishing you bought it and rtv. i did this on mitsubishi gts v6 no room at all its a bit bigger . this set up here along with the mitsubishi gt are smaller and a bit more room to work . good job. and for ppl who are scared to do this review more and take photos .again it will only go bk on one way . there are no extra bolts when you started so ..lol , putting the plenum back on dont over torque or tighten it bc it will strip . take note on which way the intake gasket sits as well bc if put on backward guess your be doing it again and flipping it or again bc you now made a vacuum leak .buy new wires, dustributor and rotor. its worth it if your down there. if your arms are to big to reach the exhaust pipe in the back and the 4 bolts holding the plenum on you can do the back from underneath up. last tip get a good set long needle nose pliers all my plug wires but one broke off at the rubber grommets at the top so had to dig them out .air compressor blow the wells clean from the rubber pieces than add plugs. this motor set up is the devil , may the Lord be with you 😂😂

Not going to lie, your casual humor gave me a lot of confidence for this project, thank you!

Thank you so much! This helped me tremendously last night! Job complete!! I also changed out the valve cover gaskets while under there!! At first I needed help with plugging the wires into the distributor correctly, but soon noticed the numbers were on the cap. Just had to look up the cylinder order...

Hey FCAS, just wanted to upate you and let you know the job is complete!! The total work time having no clue until we watched your video was roughly two and a half hours between my Wife and I with 2 ratchets, extensions, 10mm, 12mm and 14mm on our 2004 Dodge Stratus R/T 3.0L 24V. We didn't take the whole top end off as we just were doing plugs, wires, and gaskets, we just unhooked everything except a like 8" long line running from the manifold to the engine and pivoted the manifold out of the way. Everything looks great, the car is running amazingly, and we learned the previous owner still had factory plugs in the back that were so burnt you couldn't even see the white (they were deep-amber burnt, not just soot) Thank you SO much for your video, you saved us a lot of headache and money!! To anyone about to dive into this project, LABEL YOUR BOLTS! They have numbers on them (4 and 7s are different as one is a tapping bolt, and the other is normal threaded, MIXING THESE UP WILL CROSSTHREAD THE HOLES!) and you're GOLDEN! It honestly LOOKS a lot worse than it actually is, it's not nearly as hard as we thought it'd be. My only other suggestion to everyone else is grab a valve cover gasket, and the gasket for the intake manifold, because they are only a few bucks and most of the time need to be ordered from a parts store, so just have them handy that way if you DO need them, you have them, and if you don't, well you'll need them eventually anyways.

Just did mine it was hard but once you have everything off going back was easy glad I bought the best of everything

Great step by step will help a lot with my 04 eclipse I have been putting the job off due to a lack of reference this will be great help thanks a lot!

One of the worst-designed engines I've ever worked on, but your video saved me a hell of a lot of hassle. Thanks!

Thanks, much better than the other videos where they only show changing the easy ones. Appreciate the info.

Great video , had no idea where the other 3 spark plugs were

I can only imagine how hard it was to do, because it was bloody frustrating to watch! Thanks for the 'vid'!

Thank you for doing the video, now I know how to replace the spark plugs and where the egr is located at.

Great video. Now it makes sense why the shops charge so much for spark plug replacement, what a horrendous design.

great camera work buddy. thanks, very helpful.

holy crap! just bought an 04 Sebring and there ain't no way I'm doing this myself.

1999 Galant GTZ owner here. Same engine. Argh this looks like a pain in the butt. I'll have this done in the shop. I also got a vacuum leak to fix on this one.

I finally did this job. Replaced the spark plugs, wires, and the valve cover gaskets. Started it up, and the car just sounds a lot different than it did before it. Idk if it's just because I replaced everything, or it's misfiring.

Thank you So Much....I have 2002 Mit.Galant Need The Kind Job...Really Appreciate

Awesome video thank you for taking your time n being thorough, it is much appreciated

first very helpful video I've seen !!!!

Awesome video! Please do more on eclipse's I have a 02 gt & would love to learn more about this car. Thanks

Great job! I was looking for a vidoe like this.

Prepare to say "FUCK!" a LOT!

this vid was amazing thank you very much.

Great detailed video. Awesome

Really easy job to do.....really similar/common procedure for almost ALL v6 front wheel drive vehicles. Alot of people are intimidated by this type of job, but it's actually simple. You CANT replace an electrical connector in the wrong location. You CANT replace hoses where they dont belong. All the bolts are of the same grade, you just gotta pay attention to the bolt length.........................Im watching this video to get an idea of what tools I need to pack up before I replace valve cover gaskets.

Thank you for the vid. Very helpful.

Im about to do all this. Dam thats alot off stuff

I love you man! This helped out alot lol

doing this soon, thank you!

Its hard to find videos about the eclipse, thanks for taking the time to put this together, super helpful! Wish me luck this weekend ! Although, from what I understand, for an Mitsubishi Eclipse cylinders 1,3,5 are in the front correct ? 2,4,6 are in the back? This video of the Chrysler shows it opposite

Hey the metal gasket on spark plugs are on backwards ( compared to the Bosch Double Platinum that I bought and they all ready have the gasket installed on them.)

And there I was all excited on changing my spark plugs on my 02 Spyder GT, but after watching this video I might just spend those $100 dollars on a tune up to a qualified mechanic. LOL

hey I have a 2003 eclipse with the same engine and after doing tune up I'm now having problems with the car starting can't figure out what it is exactly and am curious to figuring out what the problem is

Great Video. But, after watching this I will never own a V6. I have 01 eclipse, and I would rather pay some one $100 some dollars to do it for me. Its way to complex for average car enthusiast to do it by themselves. At the same time I am afraid, with so many thing to loosen, taking off, even a good mechanic can forget to put everything back on especially when they are on tight schedule. Damn!!!! Again hats off to you for showing and doing it. Thanks

Hey, thanks so much for this video production. I would like to know what kind of mileage you would say such motor would provide on a Pajero/Montero in an urban context. Could you? I would like very much to see a video of this quality covering the possible adjustments for the lowest consumption possible with engine like this on a Montero 2000 e.g.. Also, do you have any thoughts or knowledge on an engine like this running on HH2? Thank you.

Very good video. I've done the tune up job twice, and now I have Cylinder 1 misfiring trouble. Also, I appreciate any comments, experiences on the best way to replace valve gaskets. I maybe wrong, but my take is that I'd need to unbolt the water pump bolt that torques two pulleys, so the plastic covers on top of the belts come off, which sit on top of the valve covers...Anyone has performed this job?

if you still have this car could you show me the way the spark plug cables are wired? i looked up firing order diagrams but there are two different ones

wow this pretty much the only good video about this engine. .thanks I'm about to do that I wish you could show how to replace the cover gasket. .do I have to put like a seal bond ..or just the gasket itself. .thanks again

thank you so much. awesome job

Good video but, you should have filmed the gasket replacement

tengo un problema con los sensores TPS y VSS cono los puedo remplazar es un galant 2003 v6 3.0 24

I'm going to do this and then sell my '01 Eclipse GT. This car is a pain to work on for the few things I have fixed.

I have questions about the order I should put the spark plug wires on the distributor

Need to know how to replace intake manifold gasket

how many bolts in the back of the manifold on a gts eclipse

what spark plugs should I use

I got all the bolts out of the intake like your video shows. How hard is it to pull the intake after that. It still seems it is seized. Did you have to pry it off?

I have been dealing with this for about a year and a couple months now got to get it fixed does the egr sensor have to get changed when doing this job and is it as easy as you make it look

Wow, what a colossal pain in the ass... Thanks for the video though I think I will be referring back to it a lot.

I didn't see a valve cover gasket. Does the valve cover need a gasket?

I changed my timing belt and crank sensor and I still don't have any fire what else can I check ???

my intake is stuck and won't come off and all the bolts are out need help asap

No se hablar inglés me gusta el video yo tengo un eclipse 2000 3.0l pare como este quisiera cambiar las bujillas ya que nunca se lo he cambiado

Great video

I’m doing this right now and it’s a pain in the ass I can’t get the middle egr screw with my pivot ratchet, it keeps sliding back

After I did all that to my eclipse..car won't start...I got spark and fuel..but cranks, but not starting

What was that noise you did when u pulled out the first spark plug wire 2:08

I can't get my damn valve cover of. NOTHING is connected to it. Do I have to take the timing cover off??

Asked for one coil two plugs wire transfer to cylinder each other

great job boss

Looking for an Honest answer how much does a job like this cost to do

Anyone on here familiar with the firing order and which plug goes to wish spot on the distributor? Every Diagram I can find is wrong.

And people wonder why I like my old beater.

So basically, disconnect battery cable. And remove everything connecting to the intake manifold. Vac hoses, electrical wires, ect. And to install just reverse it. If I were you I would replace the valve cover gaskets for good measure.

I have an 01 eclipse with a random misfire change spark plugs, wires, cap and some other stuff and still misfire idk what else to do. Any help. Thanks

oh man i didnt know it was difficult to do a tune up lol..... I need help with a Mitsubishi Eclipse 2001 3.0 V6 GT. I think it needs a torque converter solenoid but im not sure. Can you help?

ok so what's the wire diagram

Are you located anywhere near the tri state area ? I might just have to drop by with my eclipse for the spark plugs and some cash for you brother

I replaced the plugs and the value cover. Now I'm having smoke from the back of the block..help

I have a Chrysler sebring to , mine has the 2.5 l v6 engine in it. So im guessing theres not much difference between the 3.0 and the 2.5. besides maybe some power differences.

I just did this job on my 01 eclipse and after I put it back together the engine turns over and runs really rough. The exhaust just sounds really throaty, more throaty than before. At idle its under 1000 rpm and seems to want to turn off but it hangs in there. Any ideas on what it might be?

Wow, what a job. How much did all that cost your customer? Trying to decide if I want to tackle this in my daughters mits. Did you have to drain the coolant since you took off some of the upper hoses, or would those have drained back to the radiator? Lots of good info on your video, thanks.

whats the average price to change the thermostat on this engine?

selling a 2003 gts......needs tune up. why does Mitsubishi hate the drivers? the guy who put this together the way he did needs a tune up

By any chance do you have a video or can give any pointers on how to remove/replace the alternator for this motor? I have a 2003 Eclipse with the same motor and think the alternator is going bad. Constantly reading around 11.-11.6 volts but every now and then will jump to the 13.3-13.6 for a few seconds to minutes then back down to the 11 volt range. My battery is only a year old. Just started doing this the other day. So far I have been able to drive it but would like to fix this asap. thanks for any help

My question is how to replace the spark plug gaskets in the valve cover. Any suggestions? Thanks

what's the best plugs for this? or what plug did you used on this?

How much should this job cost to replace all spark plugs and replace both valve cover gaskets?

What is the thing you have in your hand at 6 min and 16 seconds

What is the firing order of the spark plugs?

So you drain coolant before starting the job?

I did this job today on my 01 Mitsubishi eclipse spider,Got it all back together and now it sounds like something is hitting somewhere.Any ideas what would be causing it ?? I pulled it back apart to check if the pistons were hitting the plugs and they had little dents on them ? I reinstalled the old ones and it is doing the same thing. It did not do it before. Any ideas ?????? I am stumped..

Hey, Pulled the intake manifold today. Couldn't have done it without your video. That back bracket bolt by the exhaust is a pita. Need a swivel ratchet to get it and still not easy. Since it's off I am going to replace the valve cover gasket too. Now that I can see the air intake it is filthy. Can I clean it with some throttle and intake cleaner? Thanks!

do i have to have the battery disconnected to change the spark plugs?

Did the spark plugs on my sebring 04 3.0 but wont stay on itll die back down

Galant and 6g72 should be keywords... thanks yo

why did i buy a 2001 Mitsubishi eclipse gt with the 3.0L v6 engine option on it my life sucks lol

also when replacing spark plugs do u need new wires as well

welp changing out the pluggs in my g3 eclipse today..cant wait nott!who designed that crap..dont get me wrong i love black betty but the makers hate drivers...n im guessing they never will have to change theirs ever

i have a 2000 eclipse gs and it starts and then dies after like 5 secs what do you think is causing this?

I have a 01 stratus R/T 3.0 there aint no way im doin that myself.

June88bug420 did you find out what Happened with your car?

What a pain! I think I'll let another mechanic touch my sebring...

You did all this work and installed Autolite spark plugs ?? NGK Iridiums are oem for this engine.
