Chevrolet 2011 Impala spark plug change 3.5L V6 AC Delco Iridium

[@paulc4807]

best instructional video for someone doing this on their own for the first time that ive watched. i checked atleast 6 others; some over double length in time but they werent as informative and exemplified as well as you did here.

[@Michaelsbackyardmarina]

Thank you and Thanks for watching

[@lmhicks1017]

I'm about to replace mine. I was mainly looking for a trick to get the backs so thank you. The only thing I would add is a small can of compressed air like for computers and blowing the dirt out of the spark plugs cases before removing them.

[@Colebiere]

Exactly

[@brettroper2651]

Very useful information, I also own a 2011 Impala and I’m going to replace all sensors in transmission and plugs very soon, Thanks again for the awesome content

[@Michaelsbackyardmarina]

Glad it helped

[@JanKowalski-pu2cy]

You're blessing for someone from EU, absolutely no clue for such techniques with this engines there. My parents both drive 3.5 and 3.9 GM engines. Thanks for help

[@Michaelsbackyardmarina]

Glad to help

[@TheTexican05]

NOT a fun job. Ratchet strap idea was brilliant. You're a saint for doing this AND filming it (which adds 1.5x to physical repair time). Excellent tutorial, much appreciated! 👏 🍻

[@Michaelsbackyardmarina]

Glad you enjoyed it!

[@roberthartford9171]

Great infe. Good advice on using OEM spark plugs. Plus using never seize and boot grease. I've watched a bunch of video's and no one else. mentioned it. Keep up the correct way in showing people that don't know how the right way. Job well done

[@Michaelsbackyardmarina]

Thank you for recognizing the doing it right part and thank you for watching

[@craigweis1675]

For a friend of mine. She has a 2007 w/ a 3.5-liter engine and 312,000 miles. Pulled a spark plug and it was gone, a huge gap~38"+ burned away tip and 'L' shaped wire. Way overdue. Runs like crap. Can't exceed 45 mph. [basically, the car is junk] but she's pregnant and has no money. Watching this to do this for her. At $9.97/plug I don't want to screw this up. Thanx. Merry Christmas.

[@Michaelsbackyardmarina]

That's a lot of miles and still running. I love my impala.

[@steveparlier7059]

Love the blanket tech tip 😂 I would definitely do the same man great video👍🏼😎

[@mattmgarza]

I assume 09 3.5 will be the same. Great video, thank you.

[@LM77va]

After removing the coil pack, is it necessary to ratchet the engine forward?

[@ronstickle4694]

This video is 2 years old and don't know if you will see this question.. So I am about to do this on my 06 Impala. The front plugs are easy to get to even if the wire rips off. But the wires don't want to come off easy and took some work. How do you deal with wires that will not come off easy? If they were to break off it would be a nightmare of work at cylinders 1 3 5

[@steviemaldonado2237]

Thats nice, I have an 05 3.5 Malibu I'm planning on putting new plugs in. I'm thinking I have to take out my air filter box and alternator to get a better view and room to put my fat hands in lol.

[@Michaelsbackyardmarina]

I have done that on other models as well.

[@ia4533]

I was doing backwards donuts now the car is louder and the gas mileage is like 5 miles per gallon when I am accelerating do you think that is because a spark plug came out while I was doing donuts?

[@mikeaitch62]

Just changed mine and its running kinda funky. Thinking I might of mixed the boot plugs up 😕 should of marked them like he did in the video 🤫 or maybe I ratchet strapped the motor to far up and broke something on the exhaust..

[@armadildo6468]

Im sorry this is old and not useful anymore but when you mark the spark plug wires mark also which terminal connection they came from. This keeps them from getting mixed up

[@stevenallen6245]

I have a 2011 impala and when I did my tune up I didn't even take those bolts off the mounts the only thing I did was take the coil pack off and got easy access to the back spark plugs but I guess every body has different ways of doing it 😅

[@dannysautorepair]

Great video thanks

[@Michaelsbackyardmarina]

Glad you liked it, thanks for watching

[@99jp99]

Are there any issues with loosening the dog mounts? Are there belts or anything else that require attention before or after loosening the mounts?

[@Michaelsbackyardmarina]

not that I have experienced

[@cspill99]

Just changed my spark plugs and the engine is now shaking and getting a squalling noise when I start the car(2006 Impala). Any suggestions? flashing engine light.

[@Michaelsbackyardmarina]

Well something was not done right, are all the plug wires going to the correct cylinder, where all the plugs gapped properly, are your wires in good condition. Something is fighting something here.

[@profitleads]

What are the cylinder number designations? Which are 1-3-5 and which are 2-4-6?

[@twig2123]

Rear: 1-3-5 Front: 2-4-6 Those are in order from Passenger-Center-Driver side order

[@richardcallahan8698]

If you lube the threads you must reduce installation torque. You do not want to stress the plug metal shell.

[@21FEEZY]

Thank's for the info! Where did you buy the pre gapped spark plugs? I also have an Impala.

[@Michaelsbackyardmarina]

off of amazon

[@thedirtybubble9613]

I have a 2010 Impala 3.5l with only 74k miles on it. I think I still have the original factory plugs in there. Would you recommend changing them soon? Motor runs fine but I have noticed my gas mileage gone down. Thanks.

[@Michaelsbackyardmarina]

Well if you live in the midwest or cold climate you will see your milage drop 2-3 miles per gallon. The factory plugs are good for 100K miles.

[@thedirtybubble9613]

@@Michaelsbackyardmarina I live in the Florida panhandle and while yes it does get cool here it hardly ever gets below 25 F. I did notice my fuel mileage drop in the winter versus in the summer.

[@bradphillips7074]

Check EGR tube, they corrode in these models.

[@testtesting2868]

Doing my spark plugs tomorrow on my 2010 with 120k. Why didn't you replace the wires too? I am assuming they were original. I am doing both, since the effort is the same for those rear plugs AND wires.

[@Michaelsbackyardmarina]

I purchased them and still have them over 50,000 miles later. They were in excellent condition, so I didn't. Thanks for watching

[@moisesjasso7209]

I have a question I have a 2010 Chevy Impala LT on the spark plug diagram in front of the motor is it 135 or 246

[@Michaelsbackyardmarina]

Front is 246 left to right, rear 135 left to right

[@moisesjasso7209]

It's cuz my car is making a sound well it sounds like the muffler has a hole well not that bad but it's just doesn't sound how it should be it doesn't sound like that when it's a cold start once I drive the car and the temperature of the car goes to where it should be it starts sounding like the muffler has a hole but it doesn't sound that bad

[@tropicMTV]

are these good cars, i am about to buy

[@Michaelsbackyardmarina]

They are good cars. They do have a transmission issue with shift solenoids in the transmission. I have a video on how I fixed mine. 148,000 miles and still going

[@stockstnt8]

HeyHELP😊😊😊😊 CAN YOU LI K OTHER VIDEO ABOUT SHIFT SOLENOID, WIFE N DAUGHTER DRIVE THE IMPAALA ONLY 59K MILES BUT THEY SAY IT HESITATE S BUT OF COURSE I CANNOT GET IT TO HAPPENHESITATES

[@VelleyIndustrial]

This engine, a push rod v6 and has variable valve riming.

[@jordangray9522]

well done

[@Michaelsbackyardmarina]

Thank you

[@TheMo7trm]

My impala has 120k kms on the odometer, is it early to change them? And thanks for the video.

[@Michaelsbackyardmarina]

Do you hear the screeching noise of the chirper springs? Are your brakes not stopping as good as they once did? That's not many miles unless you do a bunch of city driving. You will have to investigate and discover the need for replacement for yourself. Too many factors to consider from afar. Pull a wheel and inspect your pads.

[@TheMo7trm]

@@Michaelsbackyardmarina to be honest I know how check because I don’t have much experience in cars, but I don’t drive a lot in the city, I only use the car to commute to work and there is no any sounds and the breaks are great.

[@TheMo7trm]

@@Michaelsbackyardmarina i take the highway to go to work its like 45 minutes drive

[@meak13]

Uhh... why are you ratchet strapping and rocking your engine... I've never have or ever had to do that the change the plugs... just lay on the manifold, take off the coil packs and reach back there. Plenty of room, Unbolting the front brackets just adds more work to your list... easy peasy.

[@JoseLopez-dp9bd]

TIA

[@richardvacanti9428]

Car manufacturers make things so difficult for something that should be easy

[@Michaelsbackyardmarina]

very true

[@meak13]

It is easy... this video actually makes it harder by taking off the front brackets and rocking the engine... that's all unnecessary.

[@davekauffman8727]

GM cars are a LOT easier to work on than the minivans, my '06 Rendezvous has me cussing a blue streak.

[@craigweis1675]

When the engine is ratcheted forward ... what about the exhaust? Is it going to be dislodged? I see a 'bellows-type flex joint coming off the exhaust manifold so I guess that provides enough wiggle room. The second question is why the water pump plyers? The gap in my first post I said gap 38" I meant it's way out there 3/8+ inches ... and burned away. I saw some non-iridium plugs for less money at $3.00 each and they were listed as nickel and for a 3.5 engine. This car not going to last another 50k miles. So might work. She is still pregnant and on reduced hours at work. Has even less money now. I'm helping a little bit with her rent ... I have been reduced to begging local parts houses for a donation of ONE spark plug. If I get between 1 to 6 then I'm in hog heaven. Most houses say they won't break a pac of 4 or 6. But I keep trying. What came out of my 4.7 Jeep was the original copper plugs at 136,000 miles and I R&R'ed those at $3.07 each from O'Reilly's. Pulled the part number directly from the Jeep sticker under the engine bonnet.

[@Michaelsbackyardmarina]

Wow that was a lot of information. Good luck and thanks for watching

[@davidhouston5783]

I have 325,000 on my 09 Impala guess the spark plugs are over due.

[@Michaelsbackyardmarina]

Could use some new ones, I still need to do the wires on mine but it still getting over 29 miles per gallon. Thanks for watching

[@teddyp5220]

Noooooo, poor demo

[@jodelacruz2680]

American junk . Too much work for spark plugs

[@Michaelsbackyardmarina]

Nope it's not much work at all. Thanks for watching
