Liqui Moly Radiator flush/Cleaner 300 ml – Engine Cooling System Cleaner

Ensure your engine runs at optimum temperature and efficiency with Liqui Moly Radiator Cleaner. Over time, cooling and heating systems accumulate deposits such as lime scale, oil residues, and sludge, which block thermostats and disrupt heat exchange. This cleaner effectively removes these deposits, restoring reliable engine operation and preventing excessive wear or potential damage.

Safe for all water-cooled engines, it is fully compatible with conventional coolant additives and antifreeze (except “low conductivity” types) and is gentle on rubber and plastics. Each 300 ml bottle treats up to 10 liters of coolant, making maintenance simple and effective.

Key Benefits:

• Disperses sludge and oil residues
• Chemically converts lime deposits
• Safe for all conventional coolant systems
• Neutral effect on rubber and plastics
• Compatible with antifreeze (except low conductivity)

Application:

1. Add the full 300 ml content to the cooling system.
2. Start the heater and run the engine at operating temperature for 10–30 minutes, depending on contamination level.
3. Drain the coolant/cleaner mixture and flush the system thoroughly with water.
4. Refill the system with fresh coolant according to the vehicle manufacturer’s instructions.
