NULON R50 RADIATOR STOP LEAK 300ML AUST

Warning
Often when a cooling system has overheated and boiled, scale and sludge within the system is dislodged and can easily block the core of a radiator that was previously functioning satisfactorily. The sludge and scale can then quite easily cause a blockage in the radiator core when the engine is next operated. Always be aware of this possibility. If such a problem occurs the best course of action is to have the radiator professionally removed and cleaned.

Packaging:
300 ml bottle (12 bottles per carton)
Part No: R50

Caution
All cooling system faults should be thoroughly checked by a mechanic at the first available opportunity.

Application Rates:
Add 1 bottle for every 10 litres of water or part thereof. To protect cooling systems against corrosion and electrolysis use Nulon R45 Ultra Cool Concentrated Radiator Treatment or one of Nulon's Long Life Coolants.

Directions for Use:
Exercise caution when removing radiator caps.
Release pressure slowly to avoid scalding.

Note: If the cooling system is dirty or restricted, first clean with Nulon R40 Radiator Cleaner.

Nulon R50 is formulated with a base of fibre and fine metallic particles. R50 will not soften or harm seals and hoses. It has no effect on metals, including aluminium, and is safe to use in all radiators. R50 is compatible with all corrosion inhibitor and all other anti-freeze/anti-boil products.

Nulon Radiator Stop Leak is formulated to effectively seal leaks in radiator and heater cores, weeping cylinder head gaskets and to temporarily repair corroded welsh plugs.
