Engine Coolant

[nolafishr]

My 93 is gonna need a drain, flush and refill and I was wondering what you guys recommend and use for these first gen cummins trucks.

Some say its not good but I run a 75/25 mix of plain old school green antifreeze and distilled water,the 98cents a gallon stuff from walmart.

Peak is the only company I know of making the "Original Green" stuff. I run that in everything at a 50/50 mix.
