Plz start another thread for the blower issue, we'll see if that can be solved without buying anything you don't need!
BTW, access is pretty easy behind the glovebox & from underneath it. Check for power at the fan connector first - If power there, try 12v. direct to the fan to see if it works at all....
Then we'll give you more hints as needed!

|amc49||These coils very commonly crack, and, as you mentioned, water could have very easily gotten in crack to short coil...........|

I got the coil pack today and installed it and that did it. Running as well as it has in the 3 years or so that I've owned it. It does seem to be still leaking a little oil, as there was a little smoke after the test drive. Guess I'll be replacing a gasket soon.
Thank you for your help!
For the sake of those who may have a similar problem, a brief review:
Engine coolant was leaking and engine was overheating.
Ran the car hot too long and started running rough.
Replaced the water outlet housing - Corrected the coolant leak
Still running rough. Had engine light code checked. - Cylinder 4 Misfire.
replaced plugs (did not fix problem)
replaced wires (did not fix problem)
replaced coil pack - Bingo! Running smooth
Had I known how to troubleshoot the thing properly, I could have saved about $55.
Now on to my next problem - Blower not working...

OK, tried that. I did not get anything when I placed the end close to any metal on the engine. Just to double-check, I pulled one of the others. Before I could get it near the engine, I felt a little tingle in my fingers, so I assume that one was working...
I guess I'll replace the coil pack. Will let you know how it goes. Thanks (everyone) for your help so far.

|jetrinka||Yes that is correct. If there is any spark, holding the end of that spark plug wire close to a good ground on the engine will produce an arc that you can see.|

I did put an engine sealant into the crankcase a couple days ago. That may have cured any leaking of the gaskets.
Now, I'm not a huge fan of electricity, so let me make sure I understand what you are telling me.
I'm assuming you are saying that with the car running, pull the #4 wire off the spark plug end and place close to a metal part of the engine while holding with insulated pliers. Is that correct?

Is the car still using coolant?
If you can drive it 20 minutes without it overheating then the head and gasket are most likely intact luckily.
As far as testing the spark from the coil take the #4 spark plug wire out of its bore and using some insulated pliers, hold the end of it closely (but not touching) to a metal part of the engine (part of the block, a bolt head, etc. as long as its a good ground) and observe the spark as it arcs to the ground (if any spark is even there). It should be a bright blue color and make a loud snapping sound. If its an orange or yellow color, or no spark at all, and the plugs and wires are new, you likely have a bad coil. Zetec coils are known to crack. Perhaps some leaky coolant from that housing got on it and signed its death warrant.

OK, here's the latest. I managed to drive it to town to the local AutoZone. I had them run the diagnostics on the CEL. He told me it said "cylinder 4 misfire" (or something very similar). Recommended I try new plugs, and if that did not work, replace the wires. Well, I did both, but to no avail. He said after that I should consider replacing the coil pack.
Before I spend about $85 and an hour or two of labor on this, is this what you folks would recommend? Any other ideas? Is there any way to test the coil pack before I just blindly replace it (as it would seem my plugs and wires were probably OK to begin with...)
I'm thinking that whatever it is can't be too major if the car can make a 20 mile round trip without running hot. (Then again, maybe I'm an idiot for trying it...)
