It does a great job of keeping my KTM motorcycle running cooler in extreme heat. Hope that helps. **Q: will it make the car run cooler than with just water and anti freeze?** A: It should, it reduces the little bubbles in the coolant that reduce heat transfer, so it works with both coolant and straight water. Don't expect to fix other issues like bad radiator, water pump, thermostat, etc. **Q: Hi can i used on my model T 1926** A: It's no problem, will work on your Model T cooling system. I been using this product for 10 years. **Q: Dumb question. Can you add Distilled water if you want to?** A: Since your normal coolant solution should be antifreeze and distilled water, there is no issue. Just remember, that redline wetter doesn't take the place of all your antifreeze. You still need near a 50/50 antifreeze mix to protect your system from corrosion and freezing. ## Frequently Bought Together - Red Line 80205, Supercool Extreme Powersports Coolant, Safe for Track, Street, Off-Roa - 1/2 Gallon (64 Ounces) - Motul 104121 300V Factory Line 4T 10W-40 100% Synthetic Engine Oil 4 Liters Ester Core Technology Racing Motorcycle Motor Lubricant - K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Honda, Kawasaki, Triumph, Yamaha Motorcycles, KN-204-1 --- ## 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.hr/products/259213242-red-line-80205-engine-coolant-additive-supercool-with-waterwetter-0](https://www.desertcart.hr/products/259213242-red-line-80205-engine-coolant-additive-supercool-with-waterwetter-0) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-18*
