Its non-abrasive formula protects metal surfaces while removing deposits, helping maintain optimal cooling performance. Highly rated and trusted by automotive professionals, this lightweight cleaner is a must-have for proactive vehicle maintenance. ## Description From the manufacturer Description The work that radiators have to do nowadays is constantly growing. Downsizing and weight reduction mean that ever smaller and lighter coolant pumps have to discharge large quantities of heat, occurring in the full-load operation of the small motors. Active thermal management of the motors also leads to the pumps sometimes being switched off during vehicle use, which fosters the formation of slime and deposits in the cooling system. Impurities, wear and dirt in the cooling water circuit drive up the wear of the water pump. Also, the particles attack the shaft seal. But the cause of the problem is not resolved by replacing the water pump. It is only a matter of time before the dirt in the cooling water causes problems for the new pump, too. This is easy and affordable with the LIQUI MOLY radiator cleaner. It is simply added to the cooling water, the radiator is switched on and the motor left to run. The active ingredients then dissolve deposits, slime and dirt. After 10 to 30 minutes these are drained together with the old cooling water and the system is rinsed with water. Now it is clean and can once again deploy its full output. Also, the service life of the water pump is increased and problems with the cooling system are prevented. It is generally older vehicles in which the radiator is so heavily corroded that it has to be replaced. The damage is made worse by car owners that do not fill it with distilled water, but instead use tap water, and do not even use antifreeze. The consequence: Even more corrosion, even more impurities in the cooling water.

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 ### ⭐⭐⭐⭐⭐ Good product *by A***A on 16 May 2026* I used 2 bottles for my Subaru STI , but you have to clean it 2-3 times after it ### ⭐⭐⭐⭐⭐ As described *by F***Z on 12 December 2025* Works as expected ### ⭐⭐⭐⭐⭐ Recommended *by A***I on 8 February 2025* Good quality ## 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.be/products/253648060-2051-radiator-cleaner-300-ml](https://www.desertcart.be/products/253648060-2051-radiator-cleaner-300-ml) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-10*
