Description

Liqui-Moly Pro-Line Radiator Stop Leak K is a high-quality dispersion sealant formulated to permanently and reliably seal hairline cracks and small leaks within water-cooled engine systems. Designed to stabilise coolant pressure and prevent fluid loss, this treatment can eliminate the need for costly repairs and downtime. Compatible with aluminium radiators, antifreeze and conventional coolant additives, Pro-Line Radiator Stop Leak K circulates through the cooling system to seal problem areas without damaging the water pump, heater core or cooling components. It can also be used preventatively to reinforce system integrity before leaks develop.
