Radiator Stop Leak is a high-quality water-based sealant used to temporarily repair leaking cooling systems. Its fast-acting formulation efficiently seals radiators, heater cores, weeping head gaskets, hose joints, and Welsh plugs in vehicle engines, preventing serious engine damage caused by coolant leakage and overheating.

Application
Radiator Stop Leak is appropriate for all types of motorbikes, passenger cars, 4WDs, light and heavy-duty commercial vehicles, construction, mining, agriculture, and stationary engines.

Radiator Stop Leak is compatible with all materials, including aluminium, cast iron, copper, brass, plastics, and rubber hoses. One 375 mL bottle can treat between 6 and 12 litres. Radiator Stop Leak will not clog cooling system passageways and is compatible with antifreeze and anti-boil treatments.

Usage instructions are as follows:

• Remove the radiator cap

• Shake the bottle thoroughly before using

• Start the engine and run it for 2 minutes, with the heating turned on

• Add the items directly to the radiator

• Refill radiator and replace radiator cap

• Leave the engine and heater running for 5 minutes

• Please dispose of the bottle thoughtfully

Note:
Penrite Radiator Stop Leak is intended as a temporary remedy and does not eliminate the need for mechanical repairs. If leaks continue after use, malfunctioning parts may need to be replaced or repaired.
