Liqui Moly Pro-Line Radiator Stop Leak K radiator sealant

Pro-Line Radiator Stop Leak K is a dispersion that seals leaks in the cooling circuits of cars, trucks and buses. It seals hairline cracks and small leaks, and you can also use it preventively to avoid cooling system repairs. The solid particle dispersion is stabilised in a carrier liquid.

It is also suitable for aluminium and plastic radiators, and for cooling and heating systems with or without water filters. It is compatible with conventional coolants, antifreezes and coolant additives.

Usage

Shake before use. Add the contents to the cold cooling system and switch on the cabin heater. Then drive the vehicle for at least 10 minutes. 250 ml is enough for up to 40 l of coolant. Store free of frost.
