Cooling systems in today’s vehicles can be sensitive and a dirty radiator means it can no longer do its job as well and causes the engine temperature to rise. This not only applies if the radiator is dirty from the outside, deposits inside the cooling circuit can also push the engine temperature into the red zone. LIQUI MOLY's Pro-Line Radiator Cleaner can provide a simple solution.  

The advanced cleaning product is simply added to the radiator and the heating is switched on. The engine is then run for between 10 and 30 minutes, depending on the degree of soiling. During this time, the active ingredients dissolve oily and calcified deposits inside the cooling circuit. These are then drained together with the coolant. The cooling system should then be thoroughly flushed with water and is then ready for the new coolant.

One litre of LIQUI MOLY's Pro-Line Radiator Cleaner is sufficient for 50 litres of coolant. This makes it particularly economical to use. It is very material-friendly and contains no acids or alkalis. A radiator cleaned in this way can be restored to its full performance. This helps the engine management system to maintain the temperature in the optimum range as well as providing additional reserves under heavy engine loads.

Another useful LIQUI MOLY chemical tool is the Pro-Line Radiator Stop Leak K. This easily seals hairline cracks and minor leaks in the radiator. It is simply added to the coolant, saving tedious refilling, radiator replacement and even engine damage due to insufficient coolant. It can also be used preventively. Its active ingredients circulate in the system and are immediately available if a leak occurs, preventing unexpected malfunction. Pro-Line Radiator Stop Leak K is also suitable for aluminium and plastic radiators as well as those with water filters. It has no undesirable side effects on the water pump and heating circuit and can be mixed with all conventional coolants. One can of 250 ml is sufficient for 40 litres of coolant.
