Designed for both gasoline and diesel engines, it safeguards all cooling system metals, prevents leaks, and extends engine life with a 5-year/150,000 mile guarantee. Trusted by OEMs and backed by rigorous lab and fleet testing, this versatile concentrate adapts to extreme climates, making it the go-to choice for professional-grade engine care. ## Description Zerex from Valvoline is the #1 selling OEM-approved coolant brand. 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. Review: This is the Yellow concentrate formula, to me it's a better value than pre-diluted coolant options - After researching which Antifreeze Coolant would be best to fill a new aluminum radiator in a Dodge Ram 2500 with the Cummins Diesel, then searching around for a good deal, I found this Zerex G05 Antifreeze Coolant Concentrate 1 Gallon on sale so I ordered it and have been impressed with it so far. It has a 5 year/150,000 mile guarantee that protects against engine failure caused by freeze-ups or boil-overs. This is the Yellow concentrate formula and it is meant to be mixed with clean tap water or demineralized water (I recommend distilled water) at 50/50 ratio for temperatures -34 to 265F; 60/40 for -62 to 270F; and 70/30 for -84 to 267F. To me, concentrated versions like this are a much better value than pre-diluted coolant options are. This is yellow or gold antifreeze coolant that is G05 Phosphate free. It can be used in many, HD Diesels, Chryslers, Fords, and Mercedes Benz automobiles so it's pretty versatile. Review: Excellent choice! - Great coolant for my old 350 sbc engine. Also, price can't be beat by any other seller. I'll be purchasing Zerex G05 again. ## Features - Unsurpassed freeze protection and anti-boil performance outperforms industry standards - Hybrid organic acid technology fights rust, scale & corrosion while protecting all cooling system metals (including aluminum) - High-quality additives protect against leaks and won’t harm gaskets, hoses, plastics or original vehicle finish - Yellow concentrate formula should be mixed with clean tap water or demineralized water at 50/50 ratio for temperatures -34 to 265F; 60/40 for -62 to 270F; and 70/30 for -84 to 267F - 5 year/150,000 mile guarantee protects against engine failure caused by freeze-ups or boil-overs - Batch-tested in the lab, fleet-tested in the real world to help car and truck owners achieve optimal performance and maximize engine life. - Contains 30 – 50 ppm of denatonium benzoate as a bittering agent ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0033QNZZ0 | | Best Sellers Rank | #1,938 in Automotive (See Top 100 in Automotive) #16 in Antifreezes & Coolants | | Brand | Valvoline | | Customer Reviews | 4.8 4.8 out of 5 stars (2,059) 4.8 out of 5 stars | | Date First Available | January 11, 2010 | | Item Model Number | ZXG051 | | Item Weight | 9.62 pounds | | Manufacturer | Valvoline | | Manufacturer Part Number | ZXGO51 | | Model | G05 | | Product Dimensions | 7.38 x 3.83 x 12 inches | ## Images ![Zerex G05 Antifreeze Coolant Concentrate 1 Gallon - Image 1](https://m.media-amazon.com/images/I/81CydjTM+ML.jpg) ## Questions & Answers **Q: Is this a concentrated solution?** A: The listing for this item needs to be corrected. 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 ### ⭐⭐⭐⭐⭐ This is the Yellow concentrate formula, to me it's a better value than pre-diluted coolant options *by T***B on September 14, 2026* After researching which Antifreeze Coolant would be best to fill a new aluminum radiator in a Dodge Ram 2500 with the Cummins Diesel, then searching around for a good deal, I found this Zerex G05 Antifreeze Coolant Concentrate 1 Gallon on sale so I ordered it and have been impressed with it so far.
