Installing new coil packs.
2004 F150 XLT 4.6L 4wd (new style)
I replaced a bad coil pack the other day. When removing the origional one it made the typical "pop" as the spring and rubber boot released from the spark plug. When installing the new one (Standard Ignition #FD503)I couldn't get the COP to "snap" onto the plug. I pushed it down the best I could, screwed it in place, and plugged in the two wire connector.
With these new style coil-on-plugs, the spark plugs are 5" deep in the heads with no way to see or feel if the part is installed right.
So....How do you know if you've installed a Coil-On-Plug correctly?
The truck runs fine...
All comments are appreciated....
