I'm about to change my oil again and I need to definitely know where to locate the coil so that I can disconnect it before the live re-start after the oil has been changed. This is from a previous post:

Yes, this is part of the oil change process. I’ve posted about this in the past. A mechanic should certainly do it to avoid possible liability in the event of engine damage in his shop – DIY as a precaution. The damage described, however, is extremely rare but the coil should be removed and the engine turned with the starter motor to bring up some pressure to reposition the tensioner before a live start.

Really???

Is that true? I've had my car for almost 8 years and never did that. I just do the oil change and then I'm on my way. I guess I've been lucky huh? Is everybody doing this procedure? Has anybody had damage from not doing it?

I've never heard of that but it can't hurt, to save time removing the cover over the coil etc, why not just pull the high tension lead from the center position of the distributor, same result and much easier.?

I usually pull the CPS sensor..no spark that way and it's easy to pull from the EZL.

If ya know where the distributer is, follow the center wire ( if it's that type ) if it has a block with the wires going straight to the spark plugs pull the wires ( in a clip ) that attach to the side of the block that goes to the spark plugs. That's the long, Short of it.
