PEAK DEX-Cool® Antifreeze + Coolant, Premium Engine Coolant with Antifreeze, Car Antifreeze Coolant Mixture for GM Vehicles, 1 Gallon

Great price

I’ve been using this product in my car for the last 25 years. Yes, the bottles changed the label and changed, but the product is still been reliable for me. Never find my GM car and a little bit cheaper than that brands will put a smile on my face.

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.

Very happy with product.

Very good

Great price, was cheaper than the off market brands at my auto store, better quality cost less.

Antifreeze came in earlier than expected and worked great for our car.

Seems to let my truck keep its cool. I’ve used Peak in the past and it’s been of a good quality for keeping my vehicles happy overall. Pretty easy to mix especially if you happen to have an empty antifreeze jug and a measuring cup that you don’t want to use in the kitchen anymore. Or just go to the dollar store and get one that is at least 2 cups. 4 cups of concentrated coolant and 4 cups of distilled water into the empty container and give it a good shake then add 4 cups of distilled water to the container that was originally full then give it a good shaking! Now you have 2 gallons of 50/50 Dex-cool ready to go into your vehicle. 🚗You only need to add water if you purchase the concentrated coolant!IF YOU PURCHASE A 50/50 PRE-MIX DO NOT ADD WATER TO IT!! JUST POUR THE PRE-MIXED Coolant into your vehicle
