I guess I dont get it...Never had an issue with the green stuff. Throw a coolant filter in it preloaded with the SCA and never think about it again...
I guess I cant see spending that kind of money on coolant...

"Guys, the advantage to the ELC where our water pump is concerned, is the fact it is silicate-free (and phosphate, borate, amine, and nitrate-free too).
Conventional ("green") coolants, G-05 coolants (like Ford's Gold), and SCA additive, all have those things. Of particular concern is the silicate. Over time, silicates become insoluble and drop out of the coolant as microscopic abrasives. Silicate is a relative of silica, or sand. With that in mind, understand that the water pump on the 7.3L is not like other diesel water pumps. Instead it has a seal that is constantly exposed to the coolant. The abrasive silicates eventually find their way between the water pump's seal and shaft, causing failure. Some of the other components also form abrasives and scale. For example phosphate (found in most SCA's) actually forms an abrasive scale when mixed with H2O. Again, HD ELC's are free of silicates and other non-desirable abrasives.
Lots of things can cause your water pump to fail...belt tension, poor craftsmanship, a contaminated cooling system, etc., but your water pump probably would've lasted longer had you immediately dumped the factory coolant when it was new, and used an ELC from the start. Installing a coolant filter isn't a bad idea either.
Other advantages to the HD ELC are present in the form of better cavitation and corrosion protection, particularly as time wears on, when other lesser coolants like the G-05 Gold and conventional "green" coolants must be flushed. Better heat transfer, less maintenance, longer life, and proven heavy duty use that meet the most strict standards in the industry are others.
I've got 130K miles on my original pump...using a HD ELC from the start."
ELC is a better coolant, doing the job better, with zero silicate drop out.
While you have never had an issue with the green, ELC is actually better for L99 and up engines, without needing the same maintenance as the green.

I have driven all my PSD's to over 250k, one to almost 300k... In that time I have put two water pumps on... One on my wifes excursion and one on this 2001 and that was just because the motor was out...
It does no better job in cooling so I see no reason to spend the extra money...

Edit: Read yer post wrong.
I trust Gooch. It's a better coolant, it does the job better, and in the long run can save money, if money was a factor for anyone. It isn't for me. Just knowing I have the best stuff in my engine, the same stuff recommended by International, is good enough for me.

Let's see... Advantages of ELC: No testing, no messing with filters, no adding SCAs, no flushing every two years.... Flush green stuff twice and you spent more (time AND money) on it than you would've ELC.
Can't think of a single reason to run green (or gold even) over ELC.

Lets see...
I dont test, never have...
I dont flush, never have...
My filters come preloaded with the adittive...
I can think of a single reason to run the other... If I spring a leak, I can go to any ma and pa store and pick up some coolant... If I need to change something on the side of the road, I can go to anywhere and get good old works like oil green stuff...

uummmm... I wouldn't be leaving the green crud in there that long. Maybe it's just me. Or maybe it's that your blocks somehow have flushed themselves............... 
And if you have an issue where you HAVE to add coolant, you can add the "normal" coolant to ELC -- it just loses the ELC properties once you do. No biggie.

95psd... Never flushed, never changed, never added SCA... 250k when sold, running like a champ...
97psd... Never flushed, never changed, never added SCA...270k when sold, still running like a champ now with about 330k on it last I saw it...
99psd... drained once to replace water pump at 160k, never changed again, never drained again... errr running when traded at 280k...
01... Drained several times, changed several times, added SCA several times... 180k today, second water pump...
01 EX... 167k, Water pump replaced at 150k put the green right back in it... Add the SCA when I think about it... No issues...
I would worry more about the fuel going in then the coolant...

Again, to each his own, but I wouldn't run green more than two years. A friend of mine with a Ranger had the green stuff in his, after 4 years or so, it turned kind of a brownish black color. Ick....

But I'm finally running ELC.
