How to: Volvo T5 C30 S40 V50 C70 Spark Plug Replacement

- How to change the spark plugs on a Volvo 2.5L straight 5 cylinder turbo’d engine. This car I am working with here is a 2007 Volvo C30 T5, but this same engine was also used on the S40, V50, and C70 Volvo models, as well as some Ford models. A similar procedure can most likely be used on other Volvo models too. Typically worn spark plugs can cause poor performance, poor fuel economy, delayed throttle response, poor idling, flat spots along the rpm range, misfire, and poor emissions. Bosch has provided me with the parts in order to do the replacement and produce the video for everyone. #volvo #volvoc30 #volvot5

Tools/Supplies Needed:
-7mm socket
-8mm socket
-10mm socket
-16mm or 5/8” deep socket
-3/8” drive ratchet
-3/8” drive 3” extension
-T30 torx bit
-clean rag
-standard screwdriver
-dielectric grease
-new spark plugs
Procedure:
-open the hood
-loosen the two gear clamps on the boost pipe going over the engine using a 7mm socket
-before we get ready to remove the pipe, it’s a good idea to give it a quick wipe on the outside around the connection
-remove the two 10mm bolts which holds the boost pipe in place
-one will be on the back edge of the valve cover
-the other is located on the side of the block about the transmission
-disconnect the boost pipe on the one side
-the engine cover comes out in two pieces
-the larger cover needs to be disconnected first, it has 6 T30 torx bolts
-clean the heads of the fasteners first to remove any debris which may cause stripping
-lift the cover out
-to remove the other cover above the time belt, it has 2 T30 torx bolts
-lift the cover out
-now is a good time to inspect the timing belt for any damage, if damage is found then a replacement will be required
-using a vacuum cleaner and a brush, agitate the debris and vacuum up any loose debris
-using a stand screwdriver, disconnect each of the electrical connectors going to all the coil packs
-to remove the coils, each one has one 8mm bolt that needs to be removed
-vacuum again if needed
-twist and pull up on the coils at the same time
-using a 16mm or 5/8” deep socket with a 6” extension, remove the spark plugs
-if the spark plugs are seized, slightly loosen, tighten, slightly loosen, and tighten
-continue this until the spark plug is slowly removed, this will help break the threads free so you do not damage the threads in the head or break the spark plug
-before installing the new spark plugs, ensure they are the same length by comparing the new and old spark plugs
-considering these are iridium spark plugs, they do come pre-gapped from factory and aren’t typically recommended to be adjusted as you can damage the electrode
-install the spark plugs and torque to 22ft lbs.
-apply a small amount of dielectric grease to each of the top contacts on the spark plugs
-apply more dielectric grease to the coil pack plugs
-clean the sealing surface and then reinstall the coil packs
-install the 8mm bolts
-install the electrical connectors, then ensure all the wiring is seating correctly
-install the plastic cover over the timing belt
-install the larger engine cover and then the bolts
-reinstall the boost pipe

![How to Replace the PCV Diaphragm on a Volvo T5 [Money Saving Way]](/img/n.gif)
Excellent tutorial.
It took me a LOT longer than 9 minutes but I got the job done!
hehe. thank you!
After watching several videos, this is absolutely the best and most professional of them all. Great Job!
Thank you :)
The Spark Plug he uses is the Iridium Spark Plug part number fr7ni33. They're about 10 bucks each.
This is amazing! Worked perfectly on my gf's C70! Thank you for this video
Awesome to hear and thank you!
Just what I needed for the coil pack replacement on a V50 tomorrow😀
Excellent to hear :) I have plenty more Volvo tutorials too!
Thanks for the walkthrough. Great video highly recommend it for single moms who can't afford the mechanic!! I love that it says every tool size and the things to watch for like checking the belt..
No problem, always happy to help :) I have plenty more Volvo repair videos as well.
single moms who work on cars for the win
Spot on tutorial as always man, keep it up!
Thank you!
Thank you so much for this! Doing the job on my 09 c30 couldn't have been easier because of this video.
No problem and thank you for the feedback too!
Good tips. Easy to understand. Nice job.
Glad it was helpful and thank you :)
Outstanding and perfect. Thank you!
Thank you for the feedback! Will have more Volvo videos in the future too ;)
Thank you so much. so much informative!
No problem and thank you for the feedback :) I have plenty more Volvo tutorials as well.
Excellent video!
Thank you!
Thanks a lot looking to start a s60 engine rebuild 😁
No problem!
Whenever I have a stuck bolt I’m gonna use that method!
On the P1 5 cyl non-Turbos (i version) you need to remove the intake plenum. Make sure you get a set of gaskets (5 green o-rings) these crack frequently and cause the ecu to throw codes.
Good video as usual. I wish it was so easy to change the plugs on my Santa Fe.
Thank you! I haven't worked on a Santa Fe before, are they that bad??? I've working on early 2000 Dodge Caravans before, they needed to be on a hoist to access the rear 3 plugs.
They aren't terrible, just a pain in the ass. You have to remove a bunch of stuff and then remove the intake to get at the back three plugs. Just about any one of them I've worked on (including mine) has had the front plugs changed but the backs are usually the originals...no matter what the mileage is or what the last shop it was worked on in says. I kept them the plugs from the first Hyundai/Kia 2.7 V6 engine just to show people how bad they can get when they don't get changed.
Almost sounds like the 4cyl Ford Ranger with 8 spark plugs. You'd think being a regular maintenance item, it's made to be more accessible. Wow that is bad! Despite it being more work, there is definitely no reason to cheap at replacing the plugs. Just causes more problems in the future, not to mention the jeopardize fuel economy, performance, and reliability.
Do you know the sequence of the head by any chance? If it’s 1-5 left to right or right to left, thanks 🙏
Can i use an 3/8 + 3" extension with the 16mm for the sparkplugs?
Does these engines require thin wall spark plug socket? I did change the plugs of our 2013 Volvo S60 T5 (engine code B5254T12) today and the regular 5/8 socket made contact with the outer rim of the head which I suspect may interfere with the torque values.
What' is the spakplaks nmr from the Volvo xc70 24 turbo
So only 3 spark plugs and 3 ignition coils I thought this was a 5 cylinder what am I missing?
spark plug spec?
You should do the timing belt too!
Hey guys, do you recommend buying one 2009 on 2022?
Great video! I can't open the engine cover. The T30 screws are rusted and stuck there. Penetration oil doesn't help. What should I do in order not to slip it? Will a impact driver be better than a ratchet?
Maybe an impact driver, but you'll need to be extremely careful as you can risk cracking the cast aluminum cover. If you have a small sliding t handle, give it a smack with a hammer from the side and the shock may help it break loose.
Thanks
No problem, happy I could help!
what would you suggest first steps to do on misfire P0301, P0302 ? (c30 2008 v2 T5 automatic)
Check your plugs, that's where I'd start with first. If that passes, then move up to the boots and coils, they can be bench tested using a multimeter.
Do you have a video for removing the valve cover to replace the gasket and the tube seals? I've got oil leaking into 2/5 of my spark plug wells causing misfires.
Unfortunately I do not.
Question I found oil where my spark plugs are sitting and will need to change my valve cover gasket. Do you have a video explaining on how to do that?
Unfortunately I do not have a video for that replacement.
Awesome video! I’m about to do the same. Would you recommend replacing all the coils too? I’ve been restoring 2006 s40 t5 and I want to do it right. Vacuum lines are next.
Coils can last for a very long time and they can be checked using a multimeter.
@@4DIYers What if you have oil coming up out of the valve cover some an unknown area?? PCV system issue or anything else that I should know?? Any help much appreciated.. 2005 Volvo S40 non turbo. About to do the plugs tomorrow.
I got a 2.0 c30 , where can i find what spark plugs i need? cant seem to find info in the owners manual
Denso iridium tt20 are best. I've fitted them in my c30 2.0. Also you can find other brands just google them
Great video how long did it take you to do all this. Just wondering for a time frame
For someone that is new replacing spark plugs, no more than 3hrs. If you're experienced working on cars, then much less.
what reference number from bosch did you use?
Bosch Iridium Spark Plugs FR7NI33. Links to the parts can be found here www.boschautoparts.com/en/auto/spark-plugs/iridium-spark-plugs?partID=FR7NI33 and here www.amazon.com/Bosch-FR7NI33-Iridium-Spark-Plug/dp/B0068M5ICO
a little anti-seize on the plug threads may help ease any future plug removal
Not something I would recommend. Many spark plugs on today's market already have an "anti-seize" plating and manufacturers are against using an additional anti seize coating. When using an anti-seize coating, it can cause over torquing of the spark plug and also alter heat dissipation.
4DIYers actually did not know this. ...Learn something new every day. .thanks
No problem :)
How are the cylinders numbered on this engine brother?
I believe it's 1-2-3-4-5, starting from the timing belt cover.
What would you consider a "flat spot"?
A spot in the rpm range where the power cuts off or there's a lack of power. Years ago I had a Subaru where the plugs were so bad that I couldn't go over a certain rpm. Managed to make it home and swapped out the plugs right away.
@@4DIYers thank you!
My v50 engine doesn't look like this. I have a large plenum on top of the engine
Then you have the 2,4l non-turbo engine.
I need to do my timing belt
I think I will just pay someone...

22nm, not ft.lb of torque
22 Ft lbs is the correct value.
