2005 Volvo S40 Spark Plugs
#1
![Default](/forum/images/icons/icon1.gif)
I'm brand new to the site, so please forgive me if this has been threaded somewhere else but how do I go about changing the spark plugs on a 2005 S40 2.4i? I've been searching all over the Internet for some sort of guide but these spark plugs seem IMPOSSIBLE to find.
Am I looking in the wrong place? I've been to plenty of sites that show the spark plugs for the pre-2005 S40s, but none for the 2005 2.4i?
Any help would be greatly appreciated, especially with pictures. I can change them, have the spark plugs on hand, if I could only find the darn things...

here's a "how to" regarding changing the plugs on an '05 T5. The process should be similar enough to get you taken care of.

Here is the how to on changing the spark plugs on the T5.
Tools:
1. T-30 Star Wrench
2. Flat & Phillips screwdriver or 7mm wrench
3. 10mm socket
4. 5/8" socket
1. Whether you have an aftermarket intake or OEM one, you'll have to loosen and remove a couple items to access the engine covers. In this case we are working with an aftermarket intake.
2. First disconnect the plug that connects to the MAF sensor.

3. Then you'll have to remove two small hoses at the back of the intake pipe.

The other hose is a vacuum hose

4. There are two bolts that have to be disconnected as well. This is where you'll need your 10mm socket to remove these.

5. Once those three connections have been disconnected then you'll have to remove the intake pipe and the back of the engine. Use your 7mm wrench or screw driver to remove the clamp.

6. Once that has been loosened, just use some force to remove the intake tube.
7. To access the spark plugs you'll need to remove the engine covers. Use your T-30 Star wrench to remove the bolts the hold down the engine cover. (You'll MOST likely have to remove the oil cap to remove the engine cover)

8. Once the engine covers have been removed now its time to use your 10mm socket to loosen the bolts that hold down the coil packs.

9. Use your flat head screw driver to place under the coilpack and push up. You'll hear a suction cup "pop" when the coilpack has been popped off.

11. Now when putting your new plugs in and tightening up the new plugs first hand tighten the plug.

Then you'll want to about quarter turn the plug to insure tightness

Notice the difference?
12. Once all plugs have been replaced its a matter of just reversing your steps.
13. Make sure all connections have been placed together.
14. There you have it, you have replaced you spark plugs.
Hope this helps you when you want to replace your spark plugs yourself

Just as a follow up, based on the pictures that you posted, I was able to get a general idea of what to do.
I did, however, run into a little bit of trouble. First, the engine cover was not coming off all the way. Since I simply wanted to ACCESS the spark plugs and know where they were, I kept working on the plug furthest to the left and after some time, was able to get the boot off. I replaced that one, put everything back together (I plan on finishing the rest of them on my next day off work) but when I turned the car on, it ran for about 5 seconds before dying.
Clearly, I did something wrong. I did my best to retrace my steps and make sure I plugged everything in back the way it was. Is it just a misfire? Do these symptoms sound familiar? The engine turns, starts normal but sputters and dies within seconds...
