Hey man, I just wanted to give you a huge THANK YOU for putting out this video. You saved me a lot of money and time with your detailed instructions. I didn't have a ratchet small enough to get to that back bolt, so I removed the plastic pieces around the cabin air filter and got the room I needed. Being completely inexperienced with car repair, I managed to replace the coil and plug that was misfiring and put it all back together in about 2 hours. Thanks again!
I can only find 2 fasteners and 1 bolt, where are the others hidden?
This worked perfectly on my 2005 sts! Thanks for sharing your wisdom!
I have a 2009 CTS with 3.6 direct injection. The car has 70,000 miles on it. It had code PO302. Number 2 cylinder misfire. I ordered a coil pack from Summit Racing. They had the cheapest price, it was 40.00. I went to Oriley auto parts to get some NGK Plugs. I also picked up intake manifold gaskets, thinking I had to remove the intake. Not the case with the 2009. You can get to the coil packs without touching the intake. The Intake is narrower than older models, so you can get to everything. I was inspecting the coil packs as I pulled them. One coil pack had a grey burn spot on it. It looked like spark was jumping from the coil pack. Sure enough, that was the problem. I replaced the plugs, and one new coil pack, cleared the codes. The car runs like a rocket. Look for burn spots on the coil packs.
Hello chris one question before you change the coil was your car hesitation on low rev? My cts is a 2008 help please
Yes, it was hesitating.
+Chris Westmoreland thanks bro im gonna change de coil today to my car and plugs
look at nighttime in the dark and you can see the arcing ,,also you can see on older spark plug wire cars too, they arc as well,,and will have a white powdery look to them good lookin out
Thank you for this info.. I will change the spark plugs on my CTS 2009 and check the coils. Xoxo
I just changed all 6 Coil packs and plugs, on on my 2008 CTS 3.6DI, didnt need to pull upper Plenum, sweet !!!! Had a #4 showing a Po304 code, so figured with 66K on it, might as well change everything, and save the other 5 coil packs for later should I need one. The plugs all looked pretty good, even brown color, and no oil fouling or carbon build up. I do run 93 religiously, as welll as Mobil 1 5w30, but only change oil about once a year as its Garage kept, and driven on weekends, and vacations we dont fly on. She My RedRocket
Did it clear the 304 code? I had the same code.
Thank you for great post. no one has mentioned to change the gaskets. Great job, I'm ready to try this weekend.
Being that I was a Mr.Goodwrench back in the 80's I would have put anti-seize on the spark plug threads. For the next guy that has to remove and replace the plugs!
He's prob using acdelco plugs if he knows what's good for em...but if they used Bosch plugs then they actually recommend not using anti seize...fucken germans
Things are different now. Have to be careful what you do with each manufacturer. I never put anti-seize on plugs when working for VW, Audi and Porsche. Plus you have to take into account the type of metal used. Aluminum heads might not be pure aluminum. There can be other alloys in there as well. Research research.
Tristan Rodriguez nah, educate yourself. Clearly you’re a back yard mechanic and don’t actually wrench professionally. If you do, I’m sure comebacks are dime a dozen. There specifications for a reason, and if you torque ANY spark plug to spec, besides triton fords, and change then on time, there should be no issue or need for antiseize. Even triton fords, if you follow procedure, can be removed with little to no issue.
The best play by play. Thanks!
Great video, much needed information-thanks for posting
I had a miss when I came to a stop or park...loss no power or any miss when driving.... I replaced the plugs n coils from A1 for 230$ did it myself...n poof all is well now.06' caddy sts
Great video, gives me confidence to do it myself, thanks
Great video! Saved me a lot of time and money.
Thanks for the video, I've been wandering is this something I could do myself after watching this video, I confident that I can
This one way but I prefer to pull off the entire intake much easier to install everything and just a few extra bolts and this way u can clean the intake and check gaskets area n clean up but u need to remove the wiper assembly
just caught a lack finna get with it thanks
Made my life a lot easlier
Were you able to do this yourself
Can you make a quick video of the camshaft position sensor connector. I need to know which color wires goes to my new connector for my camshaft position sensor. Thanks
I need help!! Lol. I think I got took to the wood shed 🤦♂️ is there any reason to mess with the lower intake manifold when doing a tune up on a 07 Cadillac CTS 3.6?
Does anyone know if you can remove the #3 coil pack on a 2006 SRX 3.6l without removing the intake manifold?
About how much does this cost for a 2008 caddilac cts I have to find someone to do it and dont want to be taken advantage of. Also will this maybe solve why my car wants to die out when at a idle and when I'm going over 50mph? Also when going up small hills it putters as if it wants to die out and people have to go around me :( I changed my own air mass fuel sensor 4 months ago but I know I cant do this job :( Help! :(
I wrecked my 2011 STS 3.6 LLT so I went bought a 2008 CTS LY7 beautiful car with a blown engine...I was just gonna swap out the motor and transmission from the STS to the CTS.Will that work?
Gracias amigo ,God Bless you.
what is the right gap?
I did this and some of my spark plugs had oil on them. I put the new ones in along with the new coils anyways. Now my 2007 cadillac cts 3.6 L is idling roughly, pick up is slow, and it is eating up HELLA gas! Any ideas what may be the issue and how to fix?
Did you ever find out what the problem was with your car rough idling
Did you pull the upper Plenum? might be a vacuum leak, or if the wires electrical connection were brittle, maybe broke a wire, hate fooling with Electrical shit, Ughhhhh
What should the gap in the sparkplug be for autolite platnum plug ? On a 04 3.6L cts
Mine for 08 running factory 41-990 (?), I know the 990 is correct were gapped at .043.
I had an issue with cylinder 1 with the coil and to make sure I switched it out with cylinder 4, now the my srx won’t even start. I have a v6 motor and I also changed the spark plugs with a GAO of
.50 pre gapped. Help!
There is no tightening sequence on the intake bolts?
+Chris Westmoreland I was wondering the SAME thing?
Hey!! I was curious if you could tell me where the starter is on my 2005 cts?
+Jake Pepin drivers side...buried pretty good
Thank you.
Thanks guys
excellent video
AT LEAST YOU HAD ENOUGH LITE, WE COULD ACTUALLY SEE WHAT IT TOOK TO CHANGE THE PLUGS.
Could you please expand on the gaskets? Are they the head gaskets on the SRX?
What does car do if a coil is bad. Our Cadillac is feeling like a skip while driving. A thump feeling. Hard to explain.
Can you please tell me where the fuel pump/tank is located in a Cadillac CTS 3.6L 2007? My brother accidentally put diesel in it and we're trying to fix it.
Lexi Morgan Sorry that happened, is it full? From what I read, this fuel tank is kind of divided into two sections, with two fuel pumps. Cadillac says in the manual to drain the tank, they just siphon the fuel from where you put the fuel in, using a long hose.
But they say that even after getting the fuel out that way, on that side, there may be another 7 gallons in the other section of the fuel tank. Unfortunately I think the best way is to drop the fuel tank out of the car and get it out that way, 2nd best way is to dis-connect fuel hose/line somewhere, (fuel filter?) and somehow get the fuel pump to run, to make it pump out all the diesel.
May need to keep battery charged and not sure if diesel will do any damage to fuel pump. do not think so, but... best of luck.
Thank you so much for your speedy reply! We'll be taking your advice into consideration. He drove about 30feet after putting in diesel then that's when the car completely stopped. He put in 8 gallons of diesel (which he thought was gas at the time). We just had the car towed back to our home. Thank you again!
Hello my nieghbors 09 cadillac srx 3.6 had code for random misfire p0300,p0301,p0011,p0008 come up 3 ignitions on passenger side are not fireing I replace the plugs and all 6 c oilpacks and still has the same issue with the new 3 coil packs on passenger side not working what c ould be the problem pleas help I'm trying to help her out she has no money to put it in shop
2009 3.6di can be done without removing the intake plenum. Had to use a box wrench on # 3 cylinder coil. Other than that it was a breeze.
I did mine without taking out my intake manifold 🤣 and it was less time then this..
was it hard
is it the same on a cadillac sts
My cadillac doesn't have a spark 1986 I changed every thing please tell wat is the problem
Why are you taking the manifold off? The book says to, but we routinely change them with out removal, all 6 coils come right out with no problem.
About how long does this take to do in real time? I'd like to do this myself, but I have very little experience working on my car and my family is urging me to get quotes on labor cost from area mechanics.
What brand coil is good to use besides the expensive dealer acdelcos???
Can you do a starter on the cts please so i can put one one mine
Question. My '08 G6 GXP has 3.6L LY7. Same engine not DI. I've replaced spark plugs and coil packs but cyl #1 spark plug had some slight oil on it. The tube didn't have any oil build up really except for what may have dripped off the plug upon removal. Drove maybe 10k and checked plugs for improper wear. Now it's completely drenched dripping oil and causes misfire upon starting after sitting a couple days until it burns it all off. The other plugs are dry like normal. What could be the concern? Car has 160k miles, timing chain overhaul w/ revisions, and PVC system was replaced with revised GM parts. Only mods are a cold air intake and tb spacer. From the small amount of info available about this concern says plug tube seal is failing or valve cover or intake gasket failing. My first and worst assumption was bad piston rings and or valve seals. Any input would be appreciated! Thanks
Is the coil boot wet with oil at all? I would check the hole before taking the plug out to see if oil is just in the hole. If the hole is getting full of oil, I would just think that doing the valve cover and spark plug tube seals should take care of it. Best of luck.
Before I took the spark plug out, there has always been, since before I did tune up, a small amount of oil not enough to soak the boot on the coil. Only after I took the plug out, from the threads to the electrode was drenched. Literally dripping. This after parked for 2 days. Cleaned the plug and reinstalled. Misfires after sitting for a couple days. Driving it every day tho it doesn't misfires. If it's an internal concern then I would expect with 160k miles to burn some oil but not this excessively. Thanks
is it the same for 2005 CTS 3.6L
Yes
+Lida Rosas 2004-2007 CTS with the 3.6 are all the same.
The low profile 1/4 ratchet is available from Harbor Freight SKU 67993 and the low profile 13 mm is available from Pep Boys. I did not have to remove the wipers or the water channel.
I would like to know where you get a low profile 1/4 ratchet, the back bolt on the manifold is blocked by a water vent, I did find a low profile 13 mm. but still could not get to the bold! if you have a brand name of a ratchet, please forward.
@@DevJB The low profile 1/4 ratchet is available from Harbor Freight SKU 67993 and the low profile 13 mm is available from Pep Boys. I did not have to remove the wipers or the water channel.
@@DevJB Your welcome and Harbor Freight as another one the SKU is 67994. They did not have this one in stock at the local store. not sure if it will work, I have a 2007 CTS 3.6.
@@DevJB no problems with the paint, had a bad coil. the CRC 05319 Intake Valve Cleaner is the best.
Is this the same as Injector Coil Harnass?
2008 Cadillac CTS change spark plugs
Can you please put in the description which sockets we need? 8,10,13 and 17? You do not state it clearly anywhere in the video.
+Xenina California You will need a 13mm sweetie...
very helpful ,,,i need to replace a #five bank coil as engine light code says misfire there ,,,could you tell me where that specific coil is located on my 2005 3.6l v6 thx either way,,,very helpfull,,then next job is the round exhaust gaskets between catalytic and front pipes....do you usually have to cut those bolts out,,,or they do loosen? i dont have impact here,,jus me \\thx aginj
i replaced all 6 coils after i had a misfire on #3 after replcin #5 only ,,new iridium plugs an had exhaust mig welded two resonators in so dual exhaust straight back now too
Were you having a rough idle? Im having a rough idle an misfire on cylinder 5. Switched out the plug and put in a new coil...problem persists :(
after i switched out #5 , the enigne light stayed on but then the engine light on code read that #3 was misfiring,,,note,,,if I ran the AC it misfired so bad, you could hardly drive it,, in fact would not run AC till i fixed it,,, I bought all new coils for rockauto.com..like $40 a piece . new iridium plugs, air filter and exhaust was broke where it joined that dual inlet, dual outlet muffler in center ,,i had two smaller muffler mig welded in n have dual exhaust straight on back now. When i went to have it inspected it did not pass emissions because car needs to run without disconnecting battery which is what i did to reset engine light off,,,but i knew car was ok,, could tell by how it was runnin, so i have 200 miles with engine light off,,,and will try for sticker next week ,,should be good,, then need to fix passenger seat as does not move, ,despite all the work i had to do,, i still love the car, n hppy i bought it,,,needed like 700 in parts n my labor ,,but its the most option loaded CTS you can order , short of the corvette engined CTS V
good luck..i would go with all new coils ,,wish i them all first time, n new plugs n bet you are fine then
funny after i posted this,, and my engine light was off for 6 days and 250 miles ,,it came back on,,,i need my friend to check which code needs work,,,pain in the ass
Jay Kay
That totally sucks lol. Should make a video on it. Im really hopeing its not the ECM on my car that needs replacing.
can a coil pack be cleaned instead of being replaced
kirk Brown nope!
You don't need to take out the intake. For coil 🤣🤣. Poor macanic guy
This engine really scares me looks like the Northstar one
alll ways tell people that they have to check there gap
