Need coolant help!

We are planning on heading out tomorrow and while checking my fluids I noticed that the coolant was getting very low.

I had a shop do a coolant flush for me a couple months back and the info they gave me was that they used 'Alliance OAT ELC 50/50' , a red coolant, to fill it; however I cant find much information when searching for the same product.

Can I top it off with a similar OAT 50/50 red coolant or does it need to be the exact same thing?

It seems that the 'Alliance OAT ELC 50/50' is a nitrite free coolant, so I wouldn't want to add a nitrite coolant if at all possible. Also, it does not have any SCA so don't add a pre-charged coolant. Do you have a coolant filter? If so, it should be a blank cartridge without a chemical charge.
I recently bought Final Charge Global from NAPA which is also nitrite free. If you can't find a dealer (follow the links to Alliance) then I would go to a NAPA store.

From what I can find the Final Charge Global is ethylene glycol based, but I cant seem to find out if the Alliance coolant is as well.

It seems like my best bet is going to be to call up some shops listed on the Alliance site to try and get my hands on the same stuff.

Couldn't find sds info on it but this link has a picture that shows it containing ethylene glycol.

Thanks so much, that image is essentially what I had been looking for! If I can't get my hands on the same coolant I can at least top off with something compatible then without worrying too much.

Go to your local Freightliner dealer (they are your Thomas dealer). They have it there. It is also competitively priced, so you will not be gouged. I get my anti-freeze at our Freightliner dealer.
