Thanks for advice. my is 98 conversion van.
Finally took out 6 plugs (4 right side, and 2 left side rear), and trying to remove 2 more (left side front), but still can't figure out how to access these two.
Once done, will replace all of them.
Did you already try removing your frontwheels and going through the front wheel welds with your material? I know for certain this is the way to do it with 1997 cars. So i dont think there will be much difference with the 1998 cars, right?
-You need to raise the front part of your car with jackstands.
-Then remove the wheels. It is possible that there is still a rubber cover around the wheel wells, but that can easily be removed as well.
If you removed all the covers (there may also be some plastic covers that are attached to the car with plug ins, but they can be removed with the right tools. Or brute force...)
- Once that is done, you should be able to see the spark caps. Pull it free.
-after you removed the caps, you should be able to reach the spark plugs with a socket and an extension set.
I have completed to replace 8 plugs, and engineen runs fine now.
After I removed the engine cover, which was located at left side of front passenger seat, I could access plugs. But it needs very long and flexible arm, like a monky's...
... why else would they make a simple maintenance operation like changing spark plugs into an ordeal.
Can someone define the entry points for the driver's side front 3 plugs and the passenger side front plug?
I've looked at the wheel wells without removing the wheels ...
Addendum- I had to access the plugs through the cabin engine cover, under the hood and each wheel well.
Can anyone send a pic or URL showing the torque wrench they use?
How about the ratchet and socket too?
Addendum- ... The standard extension(s) with universal at the 5/8" plug socket work.
Is anyone using a special plug boot puller?
Addendum- ... I had one boot tear at the plug clip so now I'm shopping for replacement wires. I did, after the fact, find there is such a thing as a spark plug boot wrench. Wish I had trusted my intuition.
I spent more time removing the cabin engine cover than it usually takes me to change the 4 plugs on my Volvo.
I got the 1 far back driver side and 3 back passenger side done in the better part of a day.
I cannot imagine how I am supposed to get my hand in much less put pulling force on the remaining plug boots to remove them ... and then be able to PBBlaster the plugs to loosen them ... and fit a ratchet in there!!!
My hands are so big I couldn't get the passenger side 2nd from front started by hand because my fingers couldn't reach in far enough to hold AND turn the plug. I don't have catcher's mitts!
Inspecting and cleaning the spark plug hole is normal for me ... I just don't own the high tech flexible lighted scope to look into the hole ... much less the robotic attachment to clean anything.
