## Overview

Liqui Moly 1804 Radiator Cleaner is a 300ml non-abrasive additive designed to remove harmful deposits from all cooling and heating systems. Its acid-neutralizing formula safely restores optimal heat exchange, preventing engine overheating and wear. One bottle treats up to 10 liters of coolant, making it an efficient choice for maintaining 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.
