I've got the top of the line Bosch spark plug wires. Is it required to do the plug routing as outlined in http://dodgeram.info/tsb/1998/18-48-98/18-48-98-v8.htm TSB 18-48-98

 

Yes. There was an issue with the wire routing on 96-99 V10s that resulted in crossfire that could lead to crankshaft bearing failures, so I would guess that if a service bulletin was issued you should heed it.

 

BTW, you should change your signature. You don't have a 5.3L. Its either a 5.2L or a 5.9L.

Honestly, I didn't notice a difference between spark plug wires routed or not routed. If you have high end wires (I have the Autolite Professionals myself), I don't know if it matters for 2000 and 2001 model years. That TSB is only for up to 1999.

The way I look at it is it won't hurt, and its free, just a little bit of time, so why not?

 

my wires have never been routed according to the tsb. never had a problem either. guess it couldn't hurt, but like the old saying goes, if it ain't broke, don't fix it! lol

 

that apply's to some things like if ur universal joint is going out use ducktape lol

 

i did the re-route along with new wires and it got rid of my rpm surge. i still had the surge the last time i replaced the wires so i'm pretty sure the re-route is what got rid of it. that tsb has a few symptoms that can be from improperly routed wires so it is worth taking the time to do IMO.

 

My wires are also routed the way they were from the factory, and I have no problems. The problem is worn or cheap azz wires. Mine happen to be at least 5 year old 7mm Standard Motor Products wires.

 

Still have OEM wires on my truck recently replaced the valve cover gaskets and had issues removing the factory wire holders so I removed them with pliers wreaking them in the process. My new wire holder is on zip tie on the passenger side no problems detected so far but....

Guess I'll thank the OP for supplying a new bookmark just in case.

 

I better go check my wire routing and make sure its exactly like the tsb says. It is easy and simple thing to do to insure you have no problems with it. It would be eliminating one more problem that could happen...

 

Who ever routed my wires was an idiot. There all wacky. I never got to rout my wires that day^. Started raining about the time i got my hands on the wires. So today its clear and sunny. Im ready to rerout the wires.

I have a question. Ive got a problem also. Cant route the freakin #1 plug wire! They dont mention it in the tsb. How do you guys have your #1 wire routed? Anybody got any pics or anything that can help me out here?
