Where are the coilpacks located in a 1998 Buick LeSabre? Images would be most appreciated.
Looks like the front U.S. driver's side, unless the engine is transverse-mounted. Google got me these:
The above picture is of a 2004 model, but placement will probably be the same across most model years. Another post found via Google seems to confirm this, if you presume "left side" to mean the left side of the vehicle and not the person working on it:
To locate ignition coil (IC): open hood, to left side of engine there are 3 IC's bolted to cylinder head; they have spark plug wires attached to them (6 wires between all 3 IC's).
