Nice video. I'm here in 2024 and am soon going to tackle the same job (coils too) on my XC90 V8 Sport. My Yukon was a lot more challenging than this looks to be (mostly the passenger side rear ones). Thanks for sharing!
Great video! Lots of useful information and tips. I own a 2005 XC90 V8, as well, and I've never tackled the plugs because I didn't know how to get to the rear plugs. Thank you for sharing!
Removal of the upper engine mount cross bar helped a ton for the rear cylinder bank. Doing the front bank first to get a feel for the process and then the rears was also super helpful. The video coverage was really thorough too, great job and thanks a ton!!
Finally! Not many maintenance videos for this engine. Most owners dont DIY i guess. On the other hand, my 3rd Gen 4Runner has multiple videos for almost every task, haha. Thanks!!!
Thank you for making these videos, I already used another video you made to replace my Volvo xc90 trunk/license plates lights (1 piece) and also did that on my own! Thanks David 👍
Anyone every done the timing cover? I have a leak on the support bearing for the passenger side axle (dripping down on it) and I suspect that is the cause given that others have reported it leaking. I have yet to find a good write up on it. Mine has 213K miles.
My decision is in. I chose a B6 XC90 Ultimate over the V8 R-Design and I am very happy with the 4 Cylinder so far. I get about 4 MPG more all around and the power is ridiculous. The last trip was 28.2 MPG I can get into the Ticket Zone quite fast and merging on the Interstate is seamless with that kind of power.
Well ... Unfortunately there are at least ten gounds that attach to the engine. If there is a stumble issue, I have seen plugs that were not installed all the way even though the owner said he torqued them down. Also, could be a bad coil which you could see what cylinder is acting up and switch coils with one that is not. That is about I can think of without looking at it directly myself. Good luck I hope you figure it out.
@@A_Renaissance_Man turns out i hadn't torque the plugs all the way down and needed coils. Everything has to be tight, if they are barely lose you will have an issue so far 2 weeks no CEL.. over 209k miles runs like new
@@palejo70 when looking at the engine from the grill looking toward the firewall, the plugs, from left to right are; 1357 on the front and 2468 on the back. Therefore, 2 & 4 are on the back on the pully/belt side.
No I did not do any valve cover or intake manifold work. I had a few problems with a (new) bad O2 sensor replacement and I just had the shop do all that work.
That sounds like a problem. My Volvos fire right up. There are two oil warnings. One is low oil LEVEL and the other is low oil pressure. The bad one, low pressure also has the oil can red light on the dash. Low oil level comes one when the level falls below 1/2 quart (1 liter) from full and is really an early warning and not a danger warning like the low pressure warning.
what material of spark plug do you recommend for cold weather on the s80 or weather doesnt matter? kinda confusing since theres copper, platinum, iridium and ruthenium
Thank you for asking. For spark plugs I have learned several valuable lessons with respect to Volvos and cars in general, especially Toyotas. I highly recommend you go to an official Volvo parts web site, there are always at least two sites that are up, and look up your car and buy a pack from there. They will be Ford or NGK depending on when your vehicle was manufactured. If you insist on aftermarket the the owner's manual should guide you to a specific brand and spark plug number. The Volvo web site is competitive on price but S&H charges typically make the cost about the same a buying locally. Please do not go for anything other than what is stated in the owners manual. Too many times shops will pull them when they figure out that the plugs are a part of some mysterious future problem that pops up. With the V8, be certain that the plugs were installed correctly as the shop I deal with says they have found loose plugs installed by customers or independent shops. P.S. U.S. dealers take turns selling parts out of Volvo's warehouse and you might notice that if you buy parts over time.
Ahh ok...well I just noticed mine was shaking for some reason and I just took it to Autozone for a test. It came back with 8 indicators, All engine related misfires. I just hope my coils aren't messed up but I will have to replace my spark plugs. I "hope" thats my only problem.
Well... I am a bit bias as I like V8 engines. For the Yamaha V8 found in these Volvos, I have had and know of no issues. The only work done was not related to the engine itself but rather the surrounding items; the AC compressor, one of the O2 sensors, the transaxile splines, and that is it. The engine starts and runs and the power is really fun to feel when you really need to accelerate. Good Luck with your shopping and purchase.
@@777skinner That's true.....As long as you are 100% sure it was built 2006 onward s.....could be "old stock" when it was new & therefore pre-modification....Mmm? Safer to check the VIN codes. (I wash my engine bay....2009, but built, I believe in 2008 but I don't go crazy....nice and gentle.🤗)
Great video, How many km or miles should change these spark plugs, I have the same problem car, Ohh the V8 engines sound awesome when you take the end muffler off, see my RUclips video👍
Well ... If you look in the owners manual, spark plug maintenance and type are not listed. I changed these since this was a used vehicle and I was going for a base line. Most of the other Volvos that I owned said 120,000 mi (193000 km) and when I changed them they were fine. If gas mileage stays the same and the engine does not throw a code then I usually let them go.

So very helpful. Wasn't sure I wanted to tackle this job on my S80 but I see it's doable. Thanks.
On an s80 independent garages are charging £900. I'm guessing it's more complicated on the s80??

13 Minutes!? You’re a magician. I think I’ll do it myself next time.
Yea ... More like 13 hours. The job took me half the day. Thanks for your nice comment.

Great walkthrough! Now I’m not intimidated by this job.
Good, because this can be very intimidating for the uninitiated.

Thank you for your comment. My playlist is for Volvos but it not exclusively for the V8 XC90. Thank you for watching.

Happy to have helped you.
These videos are made for you.
Awesome video, thanks. These really are great engines.
That was amazing!!! I've had so much trouble getting to plugs on rearward facing cylinder banks I had pretty much sworn off that engine placement!
I love the Yamaha V8. Awesome engine.
You got that right!
Thanks for the video, helped to get it done!
I've never been so happy to own a 5 cylinder volvo! 😀
Toyota 3.6L V6 is even worse than this V8.

I've owned a Mitsubishi 3ltr V6, so I do understand. 😀🇦🇺
@@A_Renaissance_Man Nissan Pathfinder V6 is a b1tch too!
If you use a magnet spark plug socket you wouldn't have to use two different sockets for the spark plug
THANK GOD, they replaced the upper mount with a SOLID mount instead of the ridiculous rubber one from older volvos.

Would you choose the T5 instead of the V8 now that you know how tight it is to work on the V8 ?
My decision is in.

Thank you!
TY, DID you have to change the valve cover gaskets yet. I'm test driving a 2010 on Sat. With 95k.and doing my research.
No I did not do any valve cover or intake manifold work. I had a few problems with a (new) bad O2 sensor replacement and I just had the shop do all that work.
thanks........but you didn't use any dielectric materials for the coil and the plug.
That is correct. The factory did not use them so neither did I although I am quite sure that is a good idea.
how many miles on your motor? any troubles?
do they come pre- gapped from the dealer?
Raymond Gomez yes they are pre gapped right out of the box.
What about replacing the coils? Is that only necessary if you are experiencing a misfire or something?
I only replace coils if they throw a code and test faulty. Otherwise it is a waste of money, IMO
What size is the spark plug socket? It says 5/8" but is that the size of the fitting or socket?
5/8" or 16mm socket will fit the spark plug. It is best to measure the new ones to make sure.
why do these volvos have rough starts with low oil pressure warnings ⚠️ ?
That sounds like a problem.
My Volvos fire right up.

denso iridium - the best quality
Where do you buy the Volvo sparks?
Ubon94 I bought mine from fcpeuro
all was check gap never assume
was the car shaking before u replaced the plugs?
No. This was Preventive Maintenance as the first 50,000 mile history was unknown.

So what ended up being the issue?
Im planning to buy 2006 with 180k miles. How reliable are they with v8 engine? Thanks

Timing chain cover leaks or valve cover leaks. Expensive time consuming job many gaskets to change. Suspension parts for volvo considered consumables

These Spark Plugs come Pre-Gapped
