PEAK Fleet Charge SCA Precharged 50/50 Prediluted Antifreeze and Coolant for All Heavy Duty Engine Cooling Systems, 1 Gal.

I accidentally bought the 50/50 instead of concentrated. I did the research on this and the red with SCA that the highway trucking companies use. I use this in my 96 F150 with the 300 Inline 6. I pay attention to corrosion, acidity, / (pH) levels and also have the filter just like highway diesels have. I hate the green coolant and dont use it anymore. Not all coolant are the same and some perform better. I will be having to get a concentrated bottle to fix my mistake. The value here is better than truck stops. My experience has been it helps prevent corrosion better and makes seals, like in water pumps last longer, but you still have to maintain the pH correctly. And inside the radiator too.

Came exactly as pictured right to my door, no damages.

Great product and a good price I had to buy eight of these for my motorhome was just what I needed for a large Cummins diesel.
