Just wondering, should we be adding SCA to our cooling systems and testing, just like we do on our commercial vehicles? I got a pack of 50 test strips at FleetPride for $7 and a 1/2 gallon of treatment for $13. Much lower in price then I used to pay for Cummins Fleetguard.

Not to be stupid, but what is SCA?

Isn't the factory coolant that contains OAT that does the same thing?

"Supplemental Cooling Additives", they prevent cavitation and pitting of the cylinder walls. I will probably start treating mine, once I get around to testing it.

I would use a ELC pre mix and not worry about it.

switching from a PG or EG coolant to a ELC requires all of the pg or eg coolant be flushed well.

ELC's offer better heat transfer and boil protection, 300k+ mile life and require no sca recharge. They resist scaling better than a pg or eg, generally a better coolant all around. Where it sucks is freeze protection. It's not horrible, but it's not nearly as good as a PG.

That said i have g-05 in mine and have flushed it every oil change with new g-05.

I will swap to ELC one of these days.

edit;
I would like to add that adding sca's willy-nilly is a good way to get into trouble. I will take a photo of one of my books (a 2009 diesel tecnology book) and throw it up here, it will probably answer alot of the questions that are incoming. ELc's also offer longer water pump life.
I really don't know that it will matter, but afaik there is exactly 0 wear data out there for projected life or wear of the liners or any other friction surface, for that matter.

these are full sized images, your probably going to need to save them so you can zoom in on them.

HOAT coolant (what we got) doesn't need SCAs. If you do add any SCA to it, be prepared to drain a lot of mud out of your system. AS CRDMiller already posted, it has superior heat transfer and a higher boil temp thus, there isn't any cavitation in our engine. If you have drained the HOAT and replaced it with the green stuff, up to 3% SCA may be added, but it is of small value in such a low load, heavily recirculated circulated engine as we have.

I'm glad someone explained what an SCA was. I was thinking Society for Creative Achronisms...

Just so i am clear, we use g-05 coolant. That is what comes in our systems from the Assembly line. g-05, be it ford, chrysler, merc, or zerex, is all the same. G-05 is a PG coolant that is precharged with sca's for cavitation prevention.

g-05 is an acceptable coolant for wet lined diesel engines, if it is replaced frequently. It is not the best choice. a ELC would be the best choice.

Adding a SCA to g-05 is not harmful at all. Ford recommends the use of SCA's to it's "ford gold" (g-05) coolant for many f- series. Deere and Caterpillar also recommend the use of sca's in their g-05's for some applications. Point is it does not turn to snot. It is, however, so much easier to frequently replace g-05 in our situation that it is to attempt to maintain the sca.

Some info on g-05
http://www.whitfieldoil.com/www/docs/16 ... reeze.html
http://www.shamrockchicago.com/MSDSZerex-G-05Af.pdf

g-05 is an excellent coolant. BUT elc's are better!

Delo ELC, Rotella ELC, International's Fleetrite ELC, CAT ELC, Mobil 1 ELC
etc etc, are all excellent. The biggest advantage over g-05 is the long term stability, literally a life time fill for our crd's, if flushed properly.
Also it has better heat transfer over g-05. What it lacks is in freeze protection. 50-50 g-05 has a -34f protection and typical 50-50 elc's are -36.5F. You may say, hey no problem there, but think about it.

g-05 at it's highest recommended mixture protects down to -90F (70%)
ELC'S are usually around -60F at their max (60%)

I use g-05. There's noting wrong with it.
For the record duramax (isuzu), cummins and ford (international) light duty diesel engines used in 2500+ trucks, are all parent bore.

Earlier i said that i flushed my g-05 with new g-05 every oil change, this is true for the last 3 oil changes, because at 30k i flushed my coolant with go5, witch is clear-yellow, and the mopar g-05 is red, my coolant is somewhere in the yellow-orange zone, indicating to me that i need to continue to replace it.


g-05 is fine.
adding sca' to g-05 is ok, but i'd just flush it. And you better not do it without measuring the content.

Elc's ARE better.

One of these days when i feel like flushing with water, the viscous heater, and the heater core, i will use a elc.

Well, with 50 test strips that are going to expired in the spring, I will test the CRD's as well.

Interesting reading, written for the uninitiated. http://findarticles.com/p/articles/mi_q ... _n9453107/

My Cummins ISX came factory filled with ELC. I switched the CRD over to ELC a while back. ELC handles liner cavitation much better than the SCA style coolants.

I recently came across this stuff

http://www.evanscooling.com/coolants/

Little on the pricey side, but if it does what it says, then it will be the defacto choice for those that really want the best perfoming coolant available.
