Liqui Moly 1804 Radiator Cleaner is a 300ml non-abrasive additive designed to remove deposits from all cooling and heating systems.

Trusted by professionals and backed by over 760 positive reviews, this German-engineered solution treats up to 10 liters of cooling water, ensuring reliable engine performance and longevity.

## Description

Deposits that form in heating/radiator systems create a barrier to heat exchange and block thermostatic valves and regulation mechanisms. Too high temperatures cause the engine to run in energy-saving mode, which causes a high risk of wear and damage. The radiator cleaner reliably removes these dangerous deposits and allows the engine to run at the optimum temperature and with operational reliability.

## Questions & Answers

**Q: do you have to flush after ? 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.

### ⭐ 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.
