What does the 6.7 use for coolant? is it the Gold stuff they use in the 08 6.4, or is there something different?

I heard don't use what 6.4 uses. I'm not exactly sure what 6.7 uses though.

The 6.7L uses an all new coolant. It has never been used in any previous Powerstroke engine. It is an Organic Acid Technology. Ford will standardized on this coolant as it designs new engines. ( this coolant will eat or soften Nylon 66 or Silicone type seals and gaskets so it's not used in previous engines)
The previous Powerstroke coolants all contained some Nitrites. This coolant is Nitrite free. The test strips used on previous coolants usually were measuring that you had sufficient nitrites. On the 6.7L engine you want to make sure that you have NO nitrites. If somebody adds the wrong coolant to this engine, You need to flush and refill the coolant systems.
The 6.0 and 6.4 powerstroke engines used a VC-8 coolant revitalizer that boosted the Nitrites. The 6.7L uses a VC-12 coolant revitalizer that adds more carboxylates as the main corrosion inhibitor. Make sure you don't add the wrong revitalizer or you will need to flush and refill. So this coolant has a new test to test for enough carboxylates or corrosion inhibitors. You can add the VC-12 revitalizer twice in the coolants life ( 105,000 miles)

Just be aware, that you can't just "top off" your cooling system with any generic or universal coolant. The Ford Orange coolant is pretty new stuff and you are probably not going to find it at WalMart or Autozone. Don't add something that you don't know to be specifically compatible with it. Best bet would be safe and just add distilled water or Ionized water. Ford fills the coolant systems with Ionized water at the factory.
When you do your Check Coolant test. Remember there are two coolants systems, So you need to check each system. This coolant requires two test.. The typical test strip that checks for Nitrite and freeze point and an ALL NEW test that checks for corrosion inhibitors. Where you put a small amount of the coolant ( I think it was 5ml) into one of two vials ( depending on the coolant color) then insert another test strip.
So if you tech comes out and shows you a test strip to prove your coolant is good, Ask him where the other 3 test strips. ( should be a total of 4 test strips, two for each coolant system)

Gonna bump an old thread from the dead.
Hopefully painted horse can chime in.
I recently replaced a coolant hose to fit my intake and lost coolant from the secondary coolant system. I topped it off with the orange coolant that I bought from Ford. I didn't do the 50/50 mix with deionized water.
Will this harm my secondary coolant system? Should I flush and replace with 50/50? Leave it or flush till half way and fill the rest with deionized water?
Thanks

Yes the concentrate coolant only will harm the cooling system. Drain and mix 50/50 with distilled water asap.
