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:

GM 3800 V6 Engine

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).

@Larry - Ah, I just noticed the stamp on the first pic. You're right. However, I imagine coil pack placement will likely be the same across most model years. I believe a friend of mine has a LeSabre of the vintage in question. Maybe I'll take a look under his hood if I get the chance soon. – Iszi Mar 18 '11 at 23:13
Thanks, so to replace those, just screw them off or should I have the mechanic do it? Seems easy enough, but not for sure. Please help?! – user267 Mar 19 '11 at 3:16
@robertlewis2001 - I suggest posting that as a separate question. Also, get a Chilton or Haynes manual for your vehicle. – Iszi Mar 19 '11 at 4:17
Yeah, for replacement procedure get a service manual or – Sean Reifschneider Mar 19 '11 at 12:35
