Much faster shipping than ordering from a local vendor, price is better as well. Not much to say as its coolant. ### ⭐⭐⭐⭐⭐ Solid product for you vehicle coolant needs *by B***. on 11 May 2026* Online purchase is more cost effective than getting it at the parts store. Additionally, not all locations have this available without ordering it. I bought this for its value and convenience of Amazon delivery. Were I live (Nashville area), it is a very fast delivery. It is good to have some coolant around if doing minor adjustments or maintenance where you loose some coolant and need to top up. Or if you are doing major work requiring a full refill, get the required amount ahead of your work. Ironically, it is the coolant supplied at the dealer (but costs more needless to say). I personally like the concentrate to mix up what I need and ratio mix. I've used this product for a number of years with no difference in vehicle cooling performance from OEM. ## Frequently Bought Together - Valvoline Zerex G40 Phosphate and Nitrite Free Concentrate Antifreeze/Coolant 1 GA - Mobil 1 FS European Car Formula Full Synthetic Motor Oil 0W-40, 5 Quart - Pentosin 1405116 CHF 11S Long-Life Synthetic Hydraulic Fluid for Audi, Bentley, BMW, Chrysler, Dodge, Jeep, Mercedes-Benz, Mini, Porsche, Saab, Volkswagen, Volvo, and More; 1 Liter --- ## 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.jp/products/631829391-g40-phosphate-and-nitrite-free-concentrate-antifreeze-coolant-1-ga](https://www.desertcart.jp/products/631829391-g40-phosphate-and-nitrite-free-concentrate-antifreeze-coolant-1-ga) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-24*
