Thank you for Review: ＢMW116Iに使用。効果抜群。 Review: 普段はクーラー入れながら街乗りして電動ファン効果で85度を保ちますが、これを入れて時期的にエアコン多用しないのもありますが、ファンモーター回ってない状態で街乗り８５度きります。確かに変わります。あくまで個人的な意見ですが！ ## Features - Estimated usage amount: - Summer: Fresh water + water weater (~1 bottle) - May vary depending on usage conditions. - Winter: Fresh water + Water Wester, LLC about 30% of the total amount ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000CPI5ZK | | Amazon Bestseller | #376,034 in Automotive ( See Top 100 in Automotive ) #1,613 in Motor Oils | | Brand Name | Red Line | | Container Type | Bottle | | Customer Reviews | 4.6 4.6 out of 5 stars (3,004) | | Flash Point | 149 Degrees Celsius | | Global Trade Identification Number | 00083522802048 | | Included Components | Red Line (80204) Water Wet - Coolant Additive - 12oz Bottle | | Item Weight | 340 Grams | | Liquid Volume | 0.34 Liters | | Manufacturer | レッドライン | | Material | Aluminum | | Model Number | RED80204 | | Part Number | 80204 | | Recommended Uses For Product | home | | Specific Uses For Product | Temp | | UPC | 083522802048 172303062310 | | Upper Temperature Rating | 60 Degrees Celsius | ## Product Details - **Brand:** Red Line - **Item Weight:** 340 Grams - **Liquid Volume:** 0.34 Liters - **Material:** Aluminum - **Package Information:** Bottle ## Images ![Red Line 80204 Water Wester, 12 oz (355 ml) - Image 1](https://m.media-amazon.com/images/I/7180dmicFgL.jpg) ![Red Line 80204 Water Wester, 12 oz (355 ml) - Image 2](https://m.media-amazon.com/images/I/81T8hWwsTIL.jpg) ![Red Line 80204 Water Wester, 12 oz (355 ml) - Image 3](https://m.media-amazon.com/images/I/81TYvRGP8WL.jpg) ![Red Line 80204 Water Wester, 12 oz (355 ml) - Image 4](https://m.media-amazon.com/images/I/81ZNt4ApgiL.jpg) ![Red Line 80204 Water Wester, 12 oz (355 ml) - Image 5](https://m.media-amazon.com/images/I/91V59GKGFHL.jpg) ## Questions & Answers **Q: Compatible with hoat (orange) coolant?** A: Yes. With all coolents actually. **Q: How much will a 12 once bottle treat? I have a 5 gallon system and will be adding it to used coolant.** A: First of all I would flush & refill your coolant. I recommend Prestone 50/50 Extended Life even if your vehicle calls for Dex-Cool. Go to any place that does coolant flushes. Used coolant will not get the same results. In new coolant, the results will vary. Water Wetter will be pushed to it's limits but will still work in a 5 gallon system. The temperatures might not drop enough if stretched out that far in a large system to condone the price paid. If anything does work in this category though, it is either Water Wetter or Royal Purple's Purple Ice. **Q: Do I add this to the reservoir or the radiator?** A: Add it to the radiator, if you can. **Q: Can I use this with just distilled water in the winter without using antifreeze?** A: I have tested the water wetter at a ratio of 12 oz of to 116 oz of distilled water. i buried the gallon jug halfway deep in the snow and came out and checked the next morning early and the mix was still fluid. test this for yourself. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***ー on September 6, 2022* ＢMW116Iに使用。効果抜群。 ### ⭐⭐⭐⭐⭐ Review *by A***ー on April 21, 2020* 普段はクーラー入れながら街乗りして電動ファン効果で85度を保ちますが、これを入れて時期的にエアコン多用しないのもありますが、ファンモーター回ってない状態で街乗り８５度きります。確かに変わります。あくまで個人的な意見ですが！ ### ⭐⭐⭐⭐⭐ Review *by A***ー on May 24, 2020* 水温が下がったよ。 ## Frequently Bought Together - Red Line 80204 WaterWetter Super Coolant - 12 Ounce - PEAK 50/50 Prediluted Antifreeze and Coolant for All Engine Cooling Systems - BlueDevil Products 00203 Radiator Flush & Oil Degreaser - 1 Quart --- ## 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.sk/products/733386434-red-line-80204-water-wester-12-oz-355-ml](https://www.desertcart.sk/products/733386434-red-line-80204-water-wester-12-oz-355-ml) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-16*
