I was just going through some pics for the efan write up. Apparently, I was so excited to finally get this thing installed (started modding the fan back in March) I forgot to take any pics of the finished shroud/fan before I installed it. I guess I'm pulling it back out for a photo shoot ...
The shroud modifications may be pretty 4.2 specific. Not only are the V6 and V8 shrouds slightly different, the thickness of the stock clutch fan units are different as well. The write up may turn into more of a show-off thread

Fairlaner,
Thanks for the great write-up and pictures! I'm starting on the same project on my '97 and have a couple of questions.
1. Is the harmonic balancer/crank bolt a standard right-hand thread?
2. Does piston #1 really need to be on TDC? I think as long as the engine isn't rotated while disassembled it shouldn't make any difference. I plan to use the same method you used and mark the positions on the cam sensor.
I've done the same type of thing years ago when removing a distributer.
It is not absolutely necessary to put the crank at TDC.
The reason I did so was in case I inadvertently rotated the crank a little (after the CS was removed), I could put it back to the original position, prior the reinstalling the CS. I also did it so that if someone followed the write-up, their CS would look like the one in the pic.
Well, I just finished mine and so far it looks good. I don't see any coolant or oil leaks. Hope it stays that way.
Since mine is a '97 it had a couple of differences from your '99 but overall it was about the same job.
One thing I forgot to mark was the depth that the original crankshaft oil seal was installed in the timing cover. I was going to use a fine sharpie marker to make a line around the seal so I could install the new one to the same depth. But (typical of me) I forgot before tearing the old one out. Seems strange that there isn't a shoulder to press it up against. So I just eyeballed it when I installed the new one remembering that the seal was below the timing cover face on both sides.
Fairlane, thanks again for the write-up. It was very helpful.
Fantastic write-up and great pics of the work to be done! I have 2001 4.2L that has a coolant leak that looks like it is coming from the timing cover. I am going to tear everything down, just as you have shown and replace the gasket. The truck has 205,000 miles on it, so I think I will go ahead and replace the water pump, thermostat, and crank seal while I have everything apart. I don't usually try to "fix" things that aren't broke (could end up in a worse state) but, I don't want to have to disassemble everything a few months later if the water pump goes too.
Again, thanks for all the detail, it will save me a lot of headache and I feel a lot more confident about doing the job myself. I'm a 63 yeard old man that still likes to turn a wrench to save some money.
Well, I have ordered the replacement parts and also a cam sensor alignment tool and a harmonic balancer installation tool. I got a little scared when I saw the video on installing the balancer (link below). I figue I can sell the tools on ebay as "like new" when I'm done with the job. I will report on my success / failure when I'm done.
Having the right tools is always good ... something I seldom seem to have! If I'd watched that video prior to the repair, I think I would have gotten the balancer install tool. As it was, I don't recall having to exert any undo force to install the balancer. I did get a longer bolt to insure plenty of threads were in the crank when I pulled the balancer on.
