This depends on the rig and what the manufacturer required from Freightliner. Might help to know what rig and chassis you have.

Don't go by color as the formulations can be any color. Seeing as how Cummins is pretty much tied to Fleetguard, I would do a drain, flush, and install Fleetguard Compleat if you aren't sure. Some guys are using Final Charge

This old FMCA  thread fully explains which coolant the ISC engine calls for and how to clean, flush, and install new coolant.

You can't miss if you drain and refill with Final Charge pre-mix 50/50.  

Agree, this Peak coolant is pretty much accepted by all heavy duty diesel manufacturers.  I prefer the full strength rather than the pre-mix.  With the pre-mix you are paying for a half a gallon of water.

Please don't tell me you're using tap water in your cooling systems and flooded batteries.  As a mechanic of 50-plus years, I can tell you what contaminants in water do to them.  You will still have to buy distilled water which you have to pay for just the same.  My statement above is that you can't miss with 50/50 mix.

Well yes you can. The process/method described by Brett is one of the best guides I have seen on how to get a true 50/50 mix. That is the only way to take into consideration the water trapped in the system. Now if I am just topping up I use the mix.

In 2008 we bought a 2006 motor home with a Cat C7 engine that used coolant with SCA coolant. After draining, I used 48 gallons of distilled water to flush the whole system. I could get full strength Extended Life Coolant from Cat, now only 50/50 mix. Filled 1/2 capacity and the topped off with distilled water. I have driven 123,000+ mikes without any problems. I would change any SCA coolant to ELC.

oops, the original statement was  "You can't miss if you drain and refill with Final Charge pre-mix 50/50".

Of course I don't use tap water....and Wally World's distilled is much cheaper than Peak's.  With a little planning, mixing coolant is no problem.

I'm saving the environment by not having 2 plastic jugs.  I also think Peak can mix it better than I even though I have 55 years of experience as a mechanic.

Checking the links above, it's more cost-effective to get 50/50
