I absolutely agree!

Yeah, whether or not it's casting flash or SCA drop out, I've always thought a coolant filter was a nice idea.

I remember him mentioning it once in a post as a good idea, but nothing more in-depth.

I dunno. You don't think he was beating around the bush a little?

Stewart

 

Beating around the bush, NO. He took a chain saw to the bush.

What do you think he would say about well water? At least it's not treated with clorine and/or flouride.

 

I found it. I'll keep looking to see if he talks about it more, but here's one of his posts regarding water pump failures.
--------------------------------------------------------------------------------------------------------------------------------

"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."
--------------------------------------------------------------------------------------------------------------------------------

Here's another post where he mentions using a coolant filter is a good idea, but not needed with an ELC coolant.

--------------------------------------------------------------------------------------------------------------------------------

"S....jake, you don't need a coolant filter with HD ELC. They are silicate-free. Just make sure you do a complete flush of the system.

Of course a coolant filter is always a good idea...in any cooling system."

Thanks Stewart. That's good stuff. Also answers in part what Izzy had in the jug. If you can see it, it just might be sand and not SCA drop-out if like Gooch says "Over time, silicates become insoluble and drop out of the coolant as microscopic abrasives". But even microsopic particles can be seen with the naked eye if in abundance. If you pile up enough microsopic particles you will be able to see them.

I can barely keep my eyes open. I'm headed for bed. I'll check this thread in the morning.

Good Night Stewart.

 

There's more stuff out there by Gooch, but mainly it's pointed, specific information (like whether or not the Ford Gold is considered an ELC...it's not) to rebut someone else's misinformation.


Me too. Off to bed.

Stewart

 

I wanted to highlight this tidbit of information regarding ELC's and their compatability with SCA charged coolants:

I don't think anyone here has ever been mistaken about this, but I have read posts on other forums where someone has told a user who had inadvertently mixed an ELC with a SCA charged coolant, that they needed to backflush their block immediately before the coolant became a goo or turned into a mud like substance.

Even on the bottle of my Chevron Delo ELC it says it's compatible with other coolants. The only drawback to mixing them is you lose the extended life aspect of the ELC, depending on how diluted the mixture is.

Stewart

 

So after all this info is Given,

What would be the best Coolant to use in a 2000 PSD that has the Green Coolant in it?
Most have switched to the Gold.

But the Big Question is, ELC or No ELC ...

That is the Question?

Best,
Russ

 

It depends on how long you want to go on the same coolant. The Gold is good for 100k. The ELC three times that or more. Comes down to personal choice and/or need.

 

ELC, hands down.

Stewart

 

Thanks again for more info. You teach me something about everytime I read one of your posts. That why I stalk you.

 

According to Gooch, because the Gold (G-05) is actually a hybrid coolant, containg the same silicates the green coolant does, it has the same particles that can eat the water pump seals. It also doesn't transfer heat as well as a HD ELC does.

So to me, a HD ELC is much better than the Gold. Plus it lasts longer than the Gold, so in the long run, it's a better performer at a cheaper cost.

Stewart

 

The more you post about ELC the better I feel about doing the injector cup R&R. Thanks.

 

You're welcome!

I was supposed to create this thread a year ago! That's when I talked to Gooch about it, making sure there wasn't any updated info he wanted me to include. I just put it off, then eventually forgot about it.

I've posted most of the information found in this thread, throughout various other threads, over the last few years here in the 7.3 forum and the Excursion forum. But Gooch's flush procedure and ELC information has never been compiled into one big thread. Plus, I got tired of links to Gooch's procedure at TDS being posted here. FTE needs their own "Gooch's Radiator Flush Procedure" thread, so people here can post a link to an FTE thread, instead of being directed to TDS.

That's why I'm trying to put all of Gooch's relevant ELC information here, so this thread will be the definitive source for members who ask about ELC's or radiator flushes.

I certainly believe it deserves "Sticky Status".

 

My guess would be;
NO!
Well water would be worse than tap water way too many dissolved minerals in it.
