Impressive coolant!!!
I bought this gallon of concentrate to top off my coolant system after a minor hose repair. The chemical makeup of this brand, PEAK, has worked wonders for my 2005 H2. My engines temps have decreased after having added this coolant.I chose a 50/50 ratio and turned the gallon of concentrate into 2 gallons of mixed. The color is orange and has a consistency that is a bit thick/thicker than other brands I have used.PEAK has all sorts of variations of coolant for all manufacturers. I am glad I chose the concentrate that is specifically for GM vehicles. Price wise, it is a great value when compared to 50/50 ratios.

Good stuff.
Fair price on Peak 100% antifreeze. Purchased it to make the minimum required for free shipping. Otherwise, it is a couple bucks cheaper at the local auto parts store. Not an Amazon junkie - came to buy a not-locally-available CD.

Antifreeze is all made to specific specifications
Well you know it's antifreeze it has to be made to a certain standard to get the Dex Cool name so it's all pretty much the same thing if it says deck school on the bottle
