1968 GT500 Spark Plug Wires Installation
« on: July 18, 2021, 06:03:02 PM »
I give up trying to figure out a way to get the spark plug wires back on the spark plugs without damaging them. Does anyone know how?

Could you be more specific as putting them on without damaging is not typically a problem. You push them on until you feel them  snap over the spark terminal. Taking them off can sometimes be a problem without damaging.

     If your having difficulty with the process of the boot slipping over the spark plug, spritz a little WD40 in the terminal boot and it will slip on easier, this also allowing one to better feel the terminal 'click' in place.     ;)

Actually you should use a silicone dielectric grease such as Motorcraft XG-3-A or equivalent.

1 have lots of patience
2 put lots of silicone dielectric grease on the ends of the wires
3 find someone with strong small hands

Good luck

      Yeah, but not everyone just happens to have such as frequently laying about as WD40 which will provide for the easing of spark plug boot and terminal installation just fine.      ;)

      Now, if this were for ones' off-road vehicle which you were planning to submerge underwater, well............I probably would work a little harder at protecting and sealing things up better!      :)

I use a set of 12" needle nose pliers to install plug wires on FE's in shock tower cars like yours. They can be handy during removal too. I use DC4 dielectric grease, it makes the boots not stick to the plug when you need to remove them a few years later.

I have a tube of clear, not sure if clear is still available?
