Clarification

I've been reading up on ELC and e99s and I'm honestly confused. Some info says yes as long as your build date is after 2/98 and others say no. Mine is a 9/98, so can I run it w/o it eating up my injector cups?

As far as I know you can run ELC in anything.

First I've heard of this...

*Tip* International who made your engine, and who's engine your Ford cooling system was designed around, recommended a Heavy Duty Extended Life Coolant (HD ELC) for all 2/2/99-up built engines (SN 940614-up). These are generally red coolants with operation lives of 300K-750K miles/6-8 years, depending on brand. They are very robust and require no maintenance or additives. Popular brands include International's Fleetrite ELC, Shell Rotella ELC, CAT ELC, Chevron Delo ELC, Peak Final Charge, Prestone Heavy Duty ELC, Zerex Extreme Heavy Duty, etc.

*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 on.
Well I was apparently wrong on the date by a year lol Still confused tho.

I don't neither - which is why I was hoping some "ELC God" would bless us with his/her presence lol

Especially if the problem is in the injector cups, which don't have any o-rings to seal in the coolant.

lol I swear, the more I read, the more confused I get.

http://www.ford-trucks.com/forums/874045-final-verdict-or-still-unknown-elc-coolant-on-99-5-and-up.html

"Mostly it's the injector cups. International, who made the engine, found some compatibility issues with the older injector cup material, sensors, front cover, seals, gaskets, o-rings, and probably some other stuff when using coolants that contained organic acid technology (OAT). Coolants like ELC's (usually Red) and G-05 (usually Gold) will have these OAT's. Conventional coolants (usually Green) will not.

So International revised those components on all 2/2/99-up build engines (SN 940614-up), and began recommending and factory filling with HD ELC coolants mid-year 2000. Never looked back.

You could use HD ELC's in the older engines, but you run the risk of having to replace the cups and maybe some other stuff. I always try to recommend conventional coolant meeting ASTM D4985 with SCA or a pre-charged conventional coolant meeting ASTM D6210 for those. But it's your call, and some owners use the ELC in their older engine successfully. For the 2/2/99-up builds I would highly recommend upgrading to HD ELC.
I reckon it's really just a toss up - do I play it safe and stick w/ green and SCA or do I switch to ELC and risk damaging components but have a better coolant? hmmmmmm
