I have access to Fleet Charged coolant cheap. Is this good for out trucks? I believe I read somewhere about after a certain year was supposed to run a certain type of coolant.
Anything with an engine build date prior to 2/2/99 (SN 940614) should not use the OAT or ELC coolants. Check the sticker on your valve cover for the engine build date to be on the safe side.
Injector cups are brass, right? Why would the ELC screw with them different than in the later trucks??
The link gooch gave me explaining it all no longer works Joe. Robin says it has something to do with the sealant applied to the injector cups. I don't know if the early cups themselves were different or just the sealant. Seems like there may have also been issues with gaskets or o-rings, I really don't remember. I do remember the recommendation came from International so I would trust they had a reason for making such claims.

I don't know what OAT or ELC coolants are. What kind of coolant is recommended in these trucks with build dates prior to 2/2/99?

Chris why trucks prior to date you mentioned? So it will be fine with anything newer. I did rotella in my 02 and about to do my 01.

OAT = organic acid technology
ELC = Extended life coolant
In simple terms these are typically the anti-freeze that are not green in color.

Thanks
That's the date International changed the sealants, gaskets, o-rings and whatever else inside the motor to be compatible with the new stuff. Anything built before the change should stick with the green coolant and monitor the SCA levels. (supplemental coolant additive)
Thanks Chris -- I haven't had to mess with my cups (LOL), so I didn't know there was a sealant involved. Makes sense. I was just curious. I heard RLC wasn't good in e99 trucks but never heard exactly why until now.

Not sure if this helps or not, but this is info posted by Gooch a few years back. When I last swapped PM's with Gooch last year, he said the info was still correct and current.
According to Gooch, the noted authority on ELC's, injector cups were one of the main changes making the use of ELC's ok in the engines.
Here is a direct quote from one of Gooch's posts:
"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.
BTW, if you need to check the build date of your engine, you can find it on the valve-cover tag (driver's side), or stamped on a machined surface on the underside of the engine, behind the oil filter and just ahead of the bell-housing cover. You may need to wire brush/clean it to read it."
I am running ELC OAT coolant in my E99. I read the info by Gooch months after the chngeover. My last UOA had trace amounts of coolant. I will be changing my injector cups and using the newer sealant when I do an injector upgrade. But only time will tell if is was the cup(s) that leaked or the oil cooler.
When I'm done I will have new injectors, cups, 910-16 valve springs, and hopefully new rocker arms and pushrods.
Use a low-silicate glycol that reads "Meeds Ford Specification ESE-M97B44-A", and be sure (very important) to add an appropriate diesel Supplemental Coolant Additive (SCA) in sufficient quantity.
That all will work for you, too. If going that route, be sure to read Gooch's quote in Stewart's post #12 above about what ASTM standards to use.
