coolant question
If i understand correctly using ELC in a e-99 isnt a good thing to do....If this is so, I use Rotella ELC in my 03, we are starting a build with a e-99 motor for the 03.. Can i still use the Rotella ELC????? I will be using all the external parts off the 03 motor...

I would double check to make sure the sealant on the cups is ELC compliant. Other than that I think you would be fine to run it.

You have to worry about any E99 seal, gasket, o-ring or retaining compound that will come in contact with the ELC.

Gooch's Coolant Flush Procedure and In-Depth Coolant Information - FTE
Here's the post from that thread regarding ELC in Early '99's.

Here's the post from that thread regarding ELC in Early '99's.
The following information from Gooch pertains to why ELC's are not recommended for use in early '99 7.3L PSD's.
-------------------------------------------------------------------------------------------------------------------------------
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.
