Hey y'all, just a quick tip when swapping out your spark plugs.

They say you should only change one spark plug at a time so you don't mix up which coil pack goes where, which is a good idea, but if you're like me...you probably want to just take them all off at once, so...to never confuse which coil pack goes where try labeling them, like this for example.

I just do one at a time. That way I know which one goes where.

 

I hear you there, I just prefer to lube everything all together, use the same socket to take everything off, etc etc...I just don't like having to swap my sockets every other minute. To each their own, thousand ways to skin a cat.

 

sure is different from many years ago.

 

In reference to what exactly?

 

what are all the letters for? in my day it was one plug one cyl, one wire. what IS a coil pack? as you tell iam straight OLD SCHOOL. really i depicted this type of ignition 20 years ago.

 

The letters are to reference orientation, R = Rear and F = Front of the vehicle. Not sure exactly the purpose of the coil pack, but apparently it is what connects the ignition wire to the spark plug.

 

I just took a paint marker, and marked the number of each cylinder on its corresponding coil.

 

Upon closer inspection when I took her apart, each coil wiring connector was actually labeled from the factory...who woulda thought? Derrrrr

 

The coil packs amplify the electric charge to the spark plug to a level that will ignite the fuel. This used to be done with just one coil and a distributor, but with computers separate coils for each cylinder give much better control, power, and mpgs.
