Liqui Moly Radiator Cleaner

Liqui Moly Radiator Cleaner is a highly effective cleaning solution designed to remove harmful deposits from the cooling and heating system. Over time, oil residues, lime scale and sludge can accumulate, blocking heat exchangers, thermostats and control mechanisms. These restrictions cause elevated engine temperatures, increased fuel consumption and accelerated wear, with a significant risk of engine damage.

This formula safely dissolves oil- and lime-based deposits without the use of aggressive acids or alkalis, ensuring that the cooling system regains full flow, heat transfer efficiency and reliable operating temperatures.

Suitable for all coolant and heating systems in water-cooled engines. One 300 ml bottle treats up to 10 litres of coolant (1:33). Fully compatible with all standard coolant additives and antifreezes, except low-conductivity coolants.

Application

Add the contents directly to the cooling system.

Switch on the heater and allow the engine to run at operating temperature for 10–30 minutes, depending on contamination levels.

Once cleaning is complete:

1. Drain the coolant/cleaner mixture.
2. Thoroughly flush the system with clean water.
3. Refill with fresh coolant according to manufacturer instructions.

300 ml treats 10 litres of coolant.

Benefits:

• Disperses sludge
• Compatible with antifreeze
• Neutralises acids
• Chemical conversion of lime
• Neutral behavior on rubber and plastics
• Does not contain acids or alkali
