Product Info
The Nulon Radiator & Engine Block Stop Leak 500mL is a coolant additive that seals leaks in radiators, inlet manifolds, heater cores, gaskets and welch plugs without the need for expensive mechanical repairs. It is formulated with DuPont™ Kevlar® fibre and liquid resin, which mesh and plug a leak or crack before hardening into a strong, permanent watertight seal. The microfibre technology seeks out even small pinhole leaks and cracks up to 0.8mm in diameter or width, helping to prevent overheating and coolant loss.
Nulon Radiator & Engine Block Stop Leak is safe for use in plastic, aluminium, copper and steel radiators and heater cores, and is compatible with all glycol anti-freeze, anti-boil and water based coolants. It is poured directly into the radiator with no draining required, and one 500mL bottle treats most regular cooling systems up to 15 litres, with larger systems requiring additional bottles.
