ELC Coolant Change Over

[USAF-FD-NJ]

Changing over to an ELC. The work list for the weekend; flush cooling system, replace water pump, thermostat (203* from Dieselsite), upper water outlet, upper and lower hoses, all gaskets, fan clutch, and 8 gallons of Delo ELC coolant. I will also be using Fleetguards Restore and Restore Plus for the flush.

Anyone have any recommendations or would do anything different?

International says not to use ELC coolant in the 7.3 if it was made prior to '99. That conventional green coolant is the proper coolant.

Not to use or they started to say use of ELC is permitted when ELC was introduced? I have many that have changed over

I can't find the TSB but from gooch's flush procedures

*Tip* Due to International's compatibility tests, all pre-2/2/99 build engines (pre-SN 940614) should use a conventional coolant with the addition of SCA (or a pre-charged conventional coolant already charged with SCA). Most conventional coolants will be green, "low-silicate" and meet ASTM D4985. There are too many brands to list. They will require the addition of a supplemental coolant additive (SCA) at initial fill and maintenance of that SCA thereafter. Most pre-charged conventional coolants will be pink, purple, or blue and meet ASTM D6210. These coolants do not require an initial dose of SCA, but will require SCA maintenance thereafter. These are coolants like Peak Fleet Charge, Prestone Heavy Duty, Zerex Precharge, Shell Diesel Ready, Fleetguard Fleetcool, Fleetrite Fully Formulated, and so

The SCAs is what you need to be worried about. Use regular coolant and sca bottles or get coolant that is pre charged with it

If u were to do this i would remove the water jacket plugs in the block and flush the whole engine with distilled water to remove all the green. The reason guys use CAT coolant is because its pre charged with SCAs and other additives and combine that with a coolant filter and u have coolant that should last a long time. With out a coolant filter, no reason to spend the cash on cat coolant when u should be changing it out like regular coolant,

I have wondered what will happen when the conventional green coolant is no longer available. Around here Orielly's is the only place to get it. Napa, AZ, Advance, Auto Parts, none of them carry the green stuff.

So using a ELC could be used, but a master flush along with a filter everything should be good?
