This is the Yellow concentrate formula, to me it's a better value than pre-diluted coolant options
After researching which Antifreeze Coolant would be best to fill a new aluminum radiator in a Dodge Ram 2500 with the Cummins Diesel, then searching around for a good deal, I found this Zerex G05 Antifreeze Coolant Concentrate 1 Gallon on sale so I ordered it and have been impressed with it so far. It has a 5 year/150,000 mile guarantee that protects against engine failure caused by freeze-ups or boil-overs. This is the Yellow concentrate formula and it is meant to be mixed with clean tap water or demineralized water (I recommend distilled water) at 50/50 ratio for temperatures -34 to 265F; 60/40 for -62 to 270F; and 70/30 for -84 to 267F. To me, concentrated versions like this are a much better value than pre-diluted coolant options are. This is yellow or gold antifreeze coolant that is G05 Phosphate free. It can be used in many, HD Diesels, Chryslers, Fords, and Mercedes Benz automobiles so it's pretty versatile.

Best Anti-Freeze on the Market!!
I've used Zerex G-05 in my F-250 Super Duty for the past 5 or 6 years. Buy it straight and make my own 50/50 mix with distilled water. Highly recommend it. Next time the Benz coolant is flushed, it will be filled with Zerex too.

Excellent choice!
Great coolant for my old 350 sbc engine. Also, price can't be beat by any other seller. I'll be purchasing Zerex G05 again.
