Great additive
(Washington) | September 10th, 2021
I added this to my 6.7 ltr Cummins. I pull a 27ft travel trailer all over this beautiful country, I was beginning to notice my Temps rising when going through the mountains and when going across hotter parts of the country. I added this coolant additive before my last trip, and going up through the Cascades here in Washington pulling my trailer, my engine stayed under 200°. Before adding my Temps hovered around 210°. Another great product, from a first class company

I can't believe that this stuff helps keep the temps lower! Will buy again if needed!
Product Works Well

My Duramax was running pretty warm when pulling a fully loaded toy hauler. I knew we needed to upgrade the cooling system on the old truck, but wanted to squeeze one more trip in before we upgraded radiator, water pump, etc. I ordered this and dropped it in and was really impressed. The truck was running about 10 degrees cooler without the camper and almost 30 degrees cooler with the camper. Ordering more today just as peace of mind with the new coolant system.
