Emergency Cooling System Repair in a Bottle

Nothing ruins a weekend road trip quite like steam pouring from under the bonnet. Our 300ml Radiator Stop Leak is the emergency fix that'll get you back on the road when your cooling system decides to throw a wobbly.

Whether it's a weeping radiator, dodgy water pump seals, or a cracked cooling hose that's started letting you down, this clever solution works fast to seal the leak and buy you time to get to a proper repair. Perfect for the glove box, toolbox, or anywhere you need emergency backup.

Works With Any Cooling System

Designed for all combustion engines with closed water cooling systems, this isn't some one-trick pony. From your daily driver to the work ute, boat motor to farm machinery - if it's got a radiator and coolant, this product will sort it out.

The beauty is in its compatibility - mix it with any commercially available antifreeze without worrying about chemical reactions or damage to your cooling system. Just pour it in and let it do its thing.

Simple Application That Actually Works

No complicated procedures or special tools required. Just add the stop leak to your cooling fluid, fire up the engine, and make sure your heater valve is open so the product can circulate through the entire system. Once the leak stops, top up your coolant level and you're good to go.

One 300ml bottle is perfectly sized for cooling systems holding 5-10 litres of coolant - which covers most cars, utes, and light commercial vehicles on Aussie roads. For larger or smaller systems, simply adjust the dosage at 50ml per litre of cooling capacity.

Multiple Problem Solver

This isn't just for emergency roadside repairs. Use it preventively to seal minor leaks before they become major headaches, or to stop those annoying weeps that leave puddles under your vehicle overnight but aren't quite bad enough for a full rebuild yet.

Effective on cracked radiators, leaking heat exchangers, worn water pump seals, faulty heater valves, and even small splits in cooling hoses. It's like having a mobile radiator repair shop in your back pocket.
