Disintegrating plastic spark plug wire conduit! V70-XC70 2001

Hi All,

Has anyone had a good look under their spark plug wire cover at the split plastic conduit that protects spark plug wires from abrasion? While changing the spark plugs at 30k miles on my 2yrs old 2001 V70XC, it was all I could do to keep the conduit sheaths from crumbling to pieces while I popped the coil assemblies off.

I'm sure it's a pretty severe environment under the cover, but at 2 years, I would have expected whatever material Volvo chose to hold up a little better than that. This coming after some bad press with their disintegrating wiring harnesses in the 240.


The car is still under warranty - is this a warranty item, or do some wires actually have to short out and cause some drivability problems? I have some spools of various sizes of that split conduit, but I'd rather it not have to be my problem at this point...

Greg

Disintegrating plastic spark plug wire conduit! V70-XC70 2001

*%#$@!!! I hit 30K on my 01 last spring and noticed no deterioration. Can only imagine what I'll find under there when I next look. 59K+ now, so I'll look in the next week or so. I have no idea what Volvo will do about it, but it sounds like the stuff that nightmares are made of. Reminiscent of the problems that were documented with an early 960 a year or so ago. The owner wound up making his own replacements. I repeat. *%#$@!!!

This issue has been reported by others on various Volvo forums (Vspy, Edmunds). It affects S80 models as well. There is a service bulletin from Volvo to dealers advising them to replace the conduit with electrical tape wrapped around the wires.

A literal band aid V70-XC70 2001

Thank you. Now I know what to do, even if it hasn't happened yet. Seems a poor solution to the problem, but ask me again in twenty years. Have access to the best electrical tape on the planet. Wish I had been allowed by the Life Partner to keep the 245. Except when I'm going around corners or uphill....
