Highly rated with 4.5 stars from nearly 1,000 reviews, it’s the professional choice for maintaining radiator efficiency and prolonging engine life. ## Description Deposits that form in heating/radiator systems create a barrier to heat exchange and block thermostatic valves and regulation mechanisms.

Or can you just leave in?** A: You rinse the cooling system with water, flush it out, then refill **Q: Can this be used with aluium rad** A: Yes **Q: how large a radiator does this product clean?** A: It is based in total coolant volume. If your vehicle's coolant capacity is higher than the recommended maximum dilution quantity, you will need to purchase another. **Q: Is this a 10 minute flush or does it stay in longer?** A: Follow the instructions on the bottle. It is not recommended to drive with it in nor have multiple engine on/off cycles. Letting the car idle at least 10-15 minutes will not hurt the system, but do not be excessive. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good product for radiator cleaning and advance protection *by A***I on 28 August 2025* It cleans the radiator very well. I used full quantity and flushed with battery distilled water 3 times and radiator was cleaned completely. ### ⭐⭐⭐⭐⭐ Goodwell *by S***A on 8 July 2025* Why did you pick this product vs others?: Very nice product Jammu ### ⭐ Don't buy *by P***A on 22 February 2026* Never ever buy this . It's more dangerous than actual rust or debris. Even after 25 litres of distilled water flush after using this product still I'm getting foamy bubbles complete waste of time and efforts . If not cleared properly these bubbles with mix with coolant and do more damage to water pump. ## Frequently Bought Together - Liqui Moly Radiator Cleaner | 300 ml | Cooler additive | SKU: 2051 - Liqui Moly Pro-Line Engine Flush | 500 ml | Oil additive | SKU: 2037 - LIQUI MOLY Valve Clean | 150 ml | Petroladititive | SKU: 2001, Blue --- ## 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.com.kw/products/633521887-1804-radiator-cleaner-300-ml](https://www.desertcart.com.kw/products/633521887-1804-radiator-cleaner-300-ml) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-06-27*
