Product Information
Full details
The Liqui Moly Radiator Cleaner Flush is designed for vehicle owners looking to maintain cooling system health and prevent engine overheating. It is an ideal solution for those noticing reduced heater efficiency or suspecting sludge buildup in their cooling circuits. The product excels at removing oil, lime, and greasy residues to ensure optimal heat exchange, though it should be noted that it is a preventative and corrective maintenance fluid, not a repair liquid for mechanical leaks or damaged radiator cores.

Will this product damage my radiator seals?
No, the formula is acid-free and alkali-free, making it safe for all rubber and plastic components.
Can I leave the cleaner in the system permanently?

How much cleaner do I need for my car?
One 300ml bottle is sufficient for cooling systems with a capacity of up to 10 liters.
Does this fix a leaking radiator?
No, this is a cleaning agent only; it does not contain stop-leak additives.
Is it safe for aluminum radiators?
Yes, the product is safe for use with all common cooling system materials, including aluminum.
How often should I use this?

Troubleshooting
Heater is still not blowing hot after flush
The heater core may be mechanically blocked; consider a professional reverse-flush of the heater core specifically.
Coolant level drops after flushing
This is likely due to trapped air pockets; bleed the cooling system according to your vehicle's manual to remove air.

Setup, Compatibility & Care
Before adding the cleaner, ensure the cooling system has enough fluid capacity to accommodate the 300ml additive. The product is compatible with all cooling system designs found in internal combustion engines. To use, add the contents to the radiator or expansion tank while the engine is warm but not scalding. After the cleaning cycle, it is imperative to drain the system completely and flush it with water until clear before refilling with your manufacturer-recommended antifreeze mixture. Always check that the system is free of any physical damage, such as split hoses or corroded radiator seams, before starting the flush, as this process cannot repair structural failures.
