2005 Chrysler 300 2.7L V6 Spark Plugs and Plenum Gasket Replace

I want to share this video about changing spark plugs and plenum gaskets on a 2005 Chrysler 300 2.7L v6 engine. I forgot to mention that you should change or clean out the PCV valve because it is almost impossible to get to when the plenum is on. You might also want to double check the torque specs for your own piece of mind, I torqued mine to 7 1/2 ft lbs. Make sure you get the metal egr tube in the back on correctly without tearing the rubber washer, it's tricky. You might want to take the egr tube off from the other end at the exhaust manifold so you don't bend it.Thanks For Watching. Jeff

Hi I would like to thank you very much. This video helped me a lot step by step. It was my first time changing my spark plugs. I called a auto shop to see how much they'll change it for. They charge $380.53 at their auto shop. I only spent about $20 at autozone and some of my free time. Thank you once again for doing this step by step video.

[@leandragonzalez61]

This worked just great when I did my first spark plug and gasket replacements! Great tutorial keep more coming for Chrysler 300's!

[@tshabss]

imma do it this weekend ... I was about to pay $400.00 at the shop ... You're saving my pocket right now. Thank you for making this video.

[@jefferyk4115]

Your welcome. I would buy that foam piece that goes under the plenum before you get started though. Mine was pretty worn but I did not know that until it was off.

[@serial-glider8400]

YOU are the MAN....Thank you for the very informative video. GOD bless you sir.

[@monocancantoran6846]

Great video! Saved over $250 in labor....

[@arrow1down]

Make sure there is no air leaks at the plenum where the gaskets go. Do this by spraying carb cleaner around it and see if the engine will smooth out. If it does you might have misaligned the gasket or you don't have the plenum tightened correctly. Also make sure all the electrical connectors are back in the right place and connected. One more thing is you may have gotten a bad spark plug but that's rare.

[@jefferyk4115]

This is my video but I no longer have access to make changes. I wanted to share a bit more info which may be helpful, it comes from the repair manual. REMOVAL 2.7L Always remove the ignition coil assembly by grasping at the spark plug boot, turning the assembly 1/2 turn and pulling straight back in a steady motion. 1. Disconnect the negative battery cable. 2. Remove the intake manifold, (Refer to 9 - ENGINE/ MANIFOLDS/INTAKE MANIFOLD - REMOVAL). 3. Prior to removing the ignition coils, spray compressed air around the coil area and spark plug or contaminates from spark plug tube.. On 3.5L engines, it is necessary to loosen the screws by alternating back and forth. Do not lose the spacers under the coil when loosening the screws. 4. Remove the ignitions coil. 5. Remove the spark plug using a quality socket with a rubber or foam insert. 6. Inspect the spark plug condition. REMOVAL INTAKE MANIFOLD UPPER 1. Disconnect negative battery (1) cable. 2. Remove throttle body air inlet hose and air cleaner housing assembly (3) (Refer to 9 - ENGINE/AIR INTAKE SYSTEM/AIR CLEANER HOUSING - REMOVAL). 3. Disconnect electrical connectors from the following components: Manifold Absolute Pressure (MAP) Sensor Electronic Throttle Control Manifold Tuning Valve 4. Disconnect Vapor Purge hose, Brake Booster hose, Positive Crankcase Ventilation (PCV) hose. 5. Remove manifold support brackets (1). 6. Remove manifold attaching bolts. 7. Remove upper manifold (2). 8. Remove foam insulator (3). 9. Inspect manifold (2) (Refer to 9 - ENGINE/MANIFOLDS/ INTAKE MANIFOLD - INSPECTION).

[@kiejuanmills586]

Jeffery K pcv valve is located where..plz help

[@daweedr1649]

5:50 im on the floor laughing ....He is the definition of shade tree.

[@leadfoot97]

Thanks for video, I just did my tune up on my 07 dodge magnum v6. Oh boy I saved myself $200 :D

[@josecortes3073]

I did this process & it was very easy besides the bolts on the side, I ran into a problem with the weather that changes very quickly in Missouri! So i quickly put it back together & did a test run but of course since i did it quickly i might not had it shut right so it makes a sound of leaking air which i will wake up early tomorrow before work & redo it!

[@UwwBlake]

Thank you for your help! Saved me $500!! (Needed to replace the EGR)

[@phoenixlights9843]

The best part was when the camera guy said "action" in the beginning of the video

[@jefferyk4115]

That was my Son. R.I.P Kris

[@edcas3882]

i have a misfire on 3, is going to be a task. I'm planning on changing sparkplugs and coils, thanks for the video

[@mattastic247]

Dad's wearin' some fresh kicks too.

[@rickyrodriguez9057]

There are two ring gaskets when buying the plenum gasket... i know one goes on the egr valve tube that connects to the plenum but what about the other ring where does that one go? If u can help I would really appreciate it sir thanks

[@donnagarcia9855]

Wish I never purchased this car! Chrysler you knew what you were doing, lining the pockets of all the dealers!!! NEVER AGAIN!

[@sagetheguru]

Whats the name of the tubing that is behind the plenum cover? Mine broke but idk the name of it

[@arrow1down]

I hear ya. My son and I did the job for under 25.00.

[@tcrouch51322]

Thank you so much hopefully this saves me $ 265 tomorrow.

[@javoncook2441]

Thanks. I used this along with another video to change out one of my fuel injectors.

[@arrow1down]

You remove the metal heat tube once you get all the bolts out of the plenum. Just take your time and wiggle it gently as to not destroy the rubber grommet on the end of it. The tricky part is putting it back in, that's where you really need to be more careful so you don't break the inside of the plenum where that tube will rest. If you have a second person to help you guide it in that will be a plus. As for tightening just bring them down until your comfortable but don't over tighten.

[@Kaibil66]

Great video, thanks for uploading it. Very helpful

[@bjohnsonutube]

Success! Changed them with no problems

[@froylanmiranda7362]

The best spark plugs for 07 Chrysler 300 2.7, thanks

[@mattastic247]

super helpful video. thanks for making it!

[@automobeats]

Thanx for the info , I was a little nervous at first but it's as simple as you explained . just one thing how do you remove the plastic piece with the hose attachment that sits under the cover on the far left corner ?

[@joycejoyce5998]

very nicely done.One thing is you should get a long handle ratchet.Never remove (spark plugs) or any other bolts how you removed that first spark plug.Just not a good idea because you can bust the old spark plugs ,which leaves chips of thew ceramic laying around the plug, when you remove that plug it all goes right into cyl and can cause major issues to rings,piston tops,cyl walls and even bust new plug tips up.Just never a smart move to hit ratchets that way, it can strip things also.Very nicely done otherwise!

[@joycejoyce5998]

oh yea better be changing that timing chain/guides/tensioner/water pump every 70-80k plus find a cam chain save kit to put on it in case cam tensioner goes out it wont snap your cam chain and bend valves, just a cam stop bracket but saved a few 2.7's I've serviced/repaired

[@stevelynn7302]

2:50 it’s backwards .. you want to start loosening your bolts evenly starting from the inside working your way to the outer bolts .if you start on the corner the corners lift which will crack your manifold . If you start in the center the corners are held tightly and once you loosen the corners it will lift evenly with no damage .

[@DeAndreGodsaves]

Thanks really helped me

[@jefferyk4115]

Your welcome. Could have been a little better here and there but it works.

[@bjohnsonutube]

Great! I will have this video on my side as I'm doing it believe me..thankful again

[@arrow1down]

Glad I could help. Hope it saved you some money.

[@luzpadilla1492]

How did you remove that one air hose in back

[@217thunder]

This Video was great. I have chanaged all of the plugs and still have a misfire. I did see that one of the plugs came out with oil on it. Is this because I need to change the spark plug gasgets or is this a faulty head gasget. With the coil having so much oil built up on it should i have replaced. Would this affect the idle.

[@bjohnsonutube]

Yes, I'm about to do this over the weekend and wanted to know how I would remove that metal tube that's behind the throttle body or does it just pull out...lastly in regards to torque specs. Do you know the specifics? Or should hand tightening and the one additional ratchet to snug em in do the job

[@Mr.AllAlone]

Thanks a bunch guy your video help me big time

[@jefferyk4115]

Your very welcome. Glad I could help.

[@c00cs1]

Very good video. Thanks!

[@jefferyk4115]

I know I could have done a few things differently to make it netter but many people get the point and it has saved them money. Thanks

[@duganfr]

Thx for the video! I have a 06 with a 3.5 that need changing, everything looks the same. Auto shop bastards want to charge me $570 bucks to do it!

[@thepenitent3633]

PERFECT tutorial

[@arrow1down]

Yes it will be the same. You can get the rubber boot off an old spark plug wire end.

[@bjohnsonutube]

This process should be the same on a Dodge Charger 2.7V6, correct? Also, where did you get the rubber attachment to pull out the spark plugs if the ratchet doesn't hold on to them?

[@messproductions1]

@4:35 there is a greyish pole part that has a black thing at the tip.. looks like something that goes with the etc electronic throttle control... what is that called

[@djiv1851]

What causes oil to build up on the top back end of the plenum? The part that curves into my throttle body is oily

[@arrow1down]

Yes. You can get them from eBay for just over 7 bucks.

[@brandonjohnson9261]

Last question, I promise do I absolutely have to replace the plenum gasket or is that optional

[@vdavis55]

THANK YOU SIR!!! This was very helpful! Do you have a video on how to replace the EGR sensor??

[@robertrichardson3371]

I changed the spark plugs, load coil, and fuel injector but still getting a misfire at the same location! What else could it be?

[@christopherschauer6446]

Magnets are awesome

[@katastrophequietus]

I’d like to know the purpose of that foam under the plenum. Mine was so bad that it was crumbling. not even foam anymore it was just mush like a grease.

[@MacDrizzie1]

Hey budd, im trying to remove the intake manifold and the throttle body on my dodge charger 07 2.7liter and it looks exactly like this engine here to the teeth. @ 1:36 in your video the metal tube coming out from the throttle body, how did you get it out of there cause I dont see any screws or anything it just goes in there. This problem is starting to discourage me. Any advice?

[@rayllamas2195]

Do u got to replace the intake rubber when u change your spark plugs

[@atxjax1]

Thanks for the video. How much more work is it to replace the lower intake manifold gaskets?

[@gabrielzepeda3610]

Jackson Cruz not much after youve taken off the top

[@B2L83]

throttle sensor been replaced but they say I gotta reprogram the new to the car .. How do I do that?

[@Kaztanya93]

i own a Chrysler 300 2007 touring 3.5 engine v6 my car is showing a 1004 code would this process fix the check engine light being on

[@richman7898]

Hi I am having problems with the gasket leaking. I just bought a brand new one looked under the hood and it was leaking. Now my car doesn't crank. It make a weird noise when I try.

[@cartdogg445]

My chech engine came on, the codr stated misfire from cylinder 3. I've changed my cylinder 3 ignition coil out and replaced spark plug. When i started car it seem like it got worst, this time it even started to make backfire noise.

[@gabrielzepeda3610]

CartDogg number three is under the intake manifold in the middle, it also might be the ignition coil connector

[@Toolaholic7]

I always put in what came in from the factory.I install Champions in Chryslers only.

[@saulluna5828]

Hey I just changed my spark plugs today following your video but once I started my car back on it shakes now .... Specially when I take off Would you happen to know why? thanks!

[@jefferyk4115]

+Saul Luna Make sure there are no leaks around the plenum gasket by spraying some carb cleaner around it. If the idle gets smooth you have a air leak and need to re tighten or remove and make sure they are seated correctly. If that is not it check all the wiring you removed when you did the job and make sure everything is in it's place.

[@Johnny-km3jl]

What would happen if I did this job without disconnecting the battery because now my car is idling high

[@leadfoot97]

Fyi I needed a screw driver to help pry off the connection n hoses n the erg tube on back. The tube on back use a flat head screwdriver n pull at same time with intake loose, comes off like butter.

[@k23luna7]

Great video well detail

[@arrow1down]

Sorry I took so long to write back but you remove it once the plenum is unbolted. Just wiggle the plenum while pulling and twisting on it but do it carefully.

[@sleepy19131]

It has a bar all across in the back does that have to come out as well

[@jefferyk4115]

I believe your talking about the heat tube. No that does not have to come off but just take your time to ease it out and put it back into the plenum. If you did not start the job yet I would recommend getting the new rubber grommet for that tube just in case, and a new foam gasket for under the plenum.

[@sleepy19131]

Its a metal bar ....and ok thank you im almost done taking out all the bolts n hoses

[@jefferyk4115]

Rafael Martinez Ok good luck. Just make sure you wiggle that metal tube out slowly.

[@froylanmiranda7362]

I would go ahead and replace everything under that intake manifold might as well it's all remover and also removing the window cowl easy pizzy up and easy for EGR valve, tube, PCV valve

How u take off the air tube

[@jefferyk4115]

Well MrGreg, you must not understand the meaning of reverse the process to put it back together. It's very simple.

[@conway329]

Help I have slight vibration now that i changed the spark plug

[@jhitt79]

There is no sequence to loosening the intake bolts. Only during tightening.

[@marcaineasunder]

Great video.big help.thanks.

[@mdfurkaan8974]

Hi bro,plz help me out, I have 2007 Chrysler300, 2.7L v6,It was over heated and its water pump was gone and water and oil was mixed became milky oil.I replaced the new water pump and checked everything is fine nothing damaged, only water pump was broken,the water pump is new now but it's not starting :-(more than Three times open head and reset the timing chain, but didn't start the engine,don't know what's wrong with it.!Plz help me out.!!!

[@jefferyk4115]

+Md Furkaan Your head gasket is most likely blown. Your going to have a real job on your hands at this time and if your not experienced enough your gonna have to take it in for the repairs. It's going to need to have the heads taken off and find out which side blew so you can get that head milled, (shaved down). You should replace all the hoses at this time wile it's all apart. Change the timing chain and check the gears, spark plugs, anti freeze and all the gaskets you will get when you buy the head gasket set. Change the oil and filter. When you first start the engine after your done it may smoke like hell for a little while because you will most likely have oil and anti freeze in your exhaust system.

[@mdfurkaan8974]

Thank you so very much man,I have beefing suffering,man I'm out of country now, next month I will fix then I will text you when I will start fixing, thanks once again man, Kind regards Ken.

How do those damn wire connectors on the throttle body work

[@glenngutshall5507]

I too am having trouble getting those off. I tried them with the red slider in both positions to no avail. I also put enough force on them that I was afraid they were going to break! What's the secret?

[@shawnpecan]

Slide the lock toward the harness and then press the release tab.

[@nypuno]

do you know where the pcv valve is? Thank you

[@jefferyk4115]

+Nathaniel Puno It's behind the plenum on the passenger side and it's hard to see or get to before you remove the plenum, but once you have it off you will see it easily.

[@froylanmiranda7362]

Way to torqued a little WD 40 works that way you don't damage cylinder head

[@MRJAMES-ks9we]

What happen to the sound?

[@sscorpionbblade]

Dang!!! Gotta love the fine industrial designers of Daimler Chrysler, they are some jinga enthusiasts, the design could/should have been better but we all know they do this to increase service labor costs, smh......

Where's the pcv valve on this car, please help

[@TheAceY2k]

On the back side of the intake. It's connected from valve cover to intake.

[@trr5291]

Its alot easier to change plugs on a 2.7 intrepid. They changed the intake.

[@sauljimenez9067]

Is it the same on a 3.5

[@jefferyk4115]

Should be. If your plenum looks the same and the air intake looks the same it should be fine.

[@XelNagaPrime]

Good job . Thx
