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. ### ⭐⭐⭐⭐⭐ Impressive coolant!!! *by on Reviewed in the United States May 7, 2025* 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. ## Frequently Bought Together - PEAK DEX-Cool® Antifreeze + Coolant, Premium Engine Coolant with Antifreeze, Car Antifreeze Coolant Mixture for GM Vehicles, 1 Gallon - ACDelco GM Original Equipment PF46E Engine Oil Filter - Valvoline High Mileage with MaxLife Technology SAE 5W-30 Synthetic Blend Motor Oil 5 QT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/580769200-dex-cool-antifreeze-coolant-premium-engine-coolant-with-antifreeze-car](https://www.desertcart.co.za/products/580769200-dex-cool-antifreeze-coolant-premium-engine-coolant-with-antifreeze-car) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-04*
