My car had pink coolant before I used this. It doesn’t matter what the colour of the coolant is as long as you buy the one that is suitable for you car **Q: Does it suitable for 2011 bmw 318i - rrg sd 61 sgz** A: Sorry no, 2013 onwards only. **Q: Can I use this in a ford Smax?** A: Hi. It does say it mixes with any antifreeze but in my mechanical experience you’d be better off using genuine stuff unless you do a complete change of fluid with this make. I only say this as some don’t mix well and can cause issues further down the line ## Frequently Bought Together - CarPlan Demon Cool 34 fl Oz (1L) - Anti-Freeze & Coolant for All Cars - ITEQ Brake Fluid Liquid Tester Pen with 5 LED Indicators, Calibrated For DOT3 DOT4 Brake Fluid - ATD Tools 1106 Professional Antifreeze and Coolant Tester --- ## 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/171795508-carplan-demon-antifreeze-and-coolant-1-litre-pack-of-1](https://www.desertcart.jp/products/171795508-carplan-demon-antifreeze-and-coolant-1-litre-pack-of-1) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-16*
