Zerex G05 Antifreeze/Coolant is proven to maximize engine life in newer Ford, Chrysler and Mercedes-Benz cars, light trucks and heavy-duty vehicles. Suitable for both gasoline and diesel engines, its original long-life chemistry is specially formulated with the highest quality virgin ethylene glycol and Hybrid Organic Acid Technology (HOAT). Zerex is made for your car and protects better than industry standards against corrosion, leaking, deposits as well as freezing and boiling – the four main causes of cooling system failure, which is the leading cause of engine breakdown. Our low-silicate, reduced pH, phosphate-free formula with Hybrid Organic Acid Technology (HOAT) protects all cooling system metals (including aluminum) from corrosion. It contains nitrites that protects diesel-engine cylinder liners from cavitation, while deposit control additives guard against hardwater deposits and scale. So radiators, water pumps and other metal cooling system parts stay clean and your antifreeze flows and functions properly. Whether you’re topping off your radiator or doing a complete system flush, trust Zerex G05 Antifreeze/Coolant. Made for your car. Made by Valvoline.

The model number item ZXG051 is the concentrated version of the coolant. The model number item ZXG05RU1 is the 50/50 mix version of the coolant. The 50/50 mix version has the Amazon ASIN number of B0033QQ4VW. **Q: Is the color of this coolant orange? One customer says great replacement for green coolant. I'm trying to find a coolant for my 2011 Ford Mustang 5.0** A: It's a gold color. I used it to replace the coolant in a 05 V6 mustang. Did you get a coolant leak? Seems a little early to be replacing coolant on a 2011. **Q: bmw** A: It does not list BMW on the bottle but I'm running it in mine **Q: My 2014 caravan calls for 10 yr 150,000 mile coolant oat technology-this coolant is hoat. are they comparable?** A: Zerex G05 Phosphate Free Antifreeze/Coolant 1 GA uses HOAT chemistry, which is not recommended for your application. We recommend Zerex DEX-COOL Organic Acid Technology Antifreeze/Coolant 1 GA for your 2014 Chrysler OAT application. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great service, delivered as promised *by S***M on 2 March 2023* Loved their follow up to make sure I was satisfied ### ⭐ Price *by K***R on 7 August 2024* Markup too high for the item sold ### ⭐⭐⭐⭐⭐ Review *by M***O on 4 August 2025* Great delivery and it worked perfectly ## Frequently Bought Together - Zerex G05 Phosphate Free Concentrate Antifreeze/Coolant 1 GA - BlueDevil Products 00203 Radiator Flush & Oil Degreaser - 1 Quart - Zerex G05 Phosphate Free 50/50 Ready-to-Use Antifreeze/Coolant 1 GA --- ## 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.vu/products/291225545-valvoline-zerex-g05-phosphate-free-concentrate-antifreeze-coolant-1-ga](https://www.desertcart.vu/products/291225545-valvoline-zerex-g05-phosphate-free-concentrate-antifreeze-coolant-1-ga) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
