For the 3.0 "Vulcan" engine, it can't be much easier since the coil is sitting on the very front of the engine.
It get's much tighter on the DOHC "Duratec" engine with the coilpack mounted on the backside. Some very good ideas can be used from the suggestions / information for changing sparkplugs on these engines - See "Related Questions" below for more about that.
Changing the coil:
Alternatively, label the wires, take a picture, or draw it out BEFORE disconnecting the wires.
Coil on a 3.0 Vulcan Engine
My grand parents have a Ford Taurus 1997 3.0L gl edition. It has a coil pack on the front head tranny end. If you have the same then mark your plug wires and pull them out of the coil pack. Usually you squeeze the plug wire (they have clips holding them to the coil pack) then they're 4 small bolts that hold the coil pack down. I think there 8mm bolts. You have to pull out the wire and clip going to the coil pack also. don't forget to unhook you ground from the battery before starting all this. So go in this order:
1. unhook ground
2. number wires
3. unplug coil pack wires
4. unplug spark plug wires
5. remove 4 bolts
coil pack should come off.
ps Usually cylinder 1 2 3 is on the back and 4 5 6 is on front, but as long as you know which wire go where it doesn't matter. if you're just removing the wires from the coil pack then you could call them a b c, just as long as the wire and the place on the coil pack are marked the same.
There is no longer an ignition "distributor" on today's engine.Electrical distribution is handled by the:Powertrain Control Module (PCM),camshaft position sensor (CPS)ignition coil that looks like a rectangular distributor. NOTE: 2000-2005 Duratec engines use Coil-on-Plug (COP) in lieu of a coilpackBy the way, there is also no longer an ignition control module - that job has been passed off to the PCM.The "How do you know which wire goes where on the ignition coil and spark plugs on a Taurus - Sable" question below introduces the basics of ignition distribution - hopefully it will help folks transition from the old arrangement to the new.
if it is a dohc engine then you may have to remove the intake manifold
The 2002 Ford Taurus V-6 engine ignition coil can be found on the firewall in the engine compartment. The coil is located on the drivers side of the firewall.

Ignition what? Switch? Coil?
Replace the ignition coil(s).
Replace it only if it becomes defective.
If "heater coil" is just another term for "Heater core", then yes, most all cars have them.See "Related Questions" below for tons of information about Taurus / Sable heater cores.
Every time it becomes defective.
A 1998 Ford Taurus uses the Electronic Distributorless Ignition System ( EDIS ) with a coil pack , so there is no distributor
there is a coil on each plug
pull the two bolts buy new or used ignition coil the replace the ignition coil is on th left side of motor right by the tbi
