What exactly is ELC ?

What exactly is ELC ? Is it Extended Life Coolant ? I`m using Preston with ELC in my truck after flushing last Aug. As long as it contains no silicate isn`t that what I should be after?

ELC does stand for Extended Life Coolant

Most use ELC as an acronym to also denote the coolant having a CAT EC-1 rating, which prestone does not.
ELC means only ext. life coolant.
You are after the ELCs that meet that CAT EC-1 rating.

What would be the difference in ELC`s That one would look for when deciding what Anti-freeze to use. The reason I ask is I keep reading that it`s difficult to find for some. But when I look in Wal-mart there`s several different brand names with ELC. Is there really a difference ?

ELC = Extended Life Coolant...now there are a lot of coolants that claim to be extended life. On this forum when people refer to ELC's they are talking about coolants meeting Cat EC-1, Cummins 14603 and/or Navistar B-2.

Cat ELC, Rotella ELC, Delo ELC, Primatech ELC, Zerex ELC etc etc are all popular brands.

The reason I`m asking is because last year I flushed, restored, and VC-9`d and in doing so I partially clogged my oil cooler. My deltas were 20+. Now I am doing the upgraded oil cooler, EGR delete, coolant filter, Turbo cleaning,Blue spring upgrade and the Turbo pluming upgrade. Finances prohibit me from doing another flush at this time. But shouldn`t I be alright for now since I did remove the silicate from the system with the previous flush? For now just watch the coolant filter for trash and re flush later when finances allow.

Yeah, don't chemical flush again, but I would do a couple distilled water flushes and re-fill with a better ELC coolant (not Prestone). I used Zerex Extended Life HD from NAPA, which has the CAT EC-1 rating.
